Facilitating Implementation of Next Generation 911 Services 
(NG911); Improving 911 Reliability

AGENCY: Federal Communications Commission.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: In this document, the Federal Communications Commission (the 
FCC or Commission) adopts rules to ensure that emerging Next Generation 
911 (NG911) networks are reliable and interoperable. NG911 is replacing 
legacy 911 technology across the country with internet Protocol (IP)-
based infrastructure that will support new 911 capabilities, including 
text, video, and data. However, for NG911 to be fully effective, NG911 
networks must be designed to safeguard the reliability of critical 
components and support the interoperability needed to seamlessly 
transfer 911 calls and data from one network to another. The rules 
require entities essential to delivering emergency calls in the NG911 
environment to implement common sense measures to safeguard the 
reliability of NG911 networks and reduce the risk of 911 outages, and 
require certain entities to report on their support for NG911 
interoperability. The rules also eliminate unnecessary and burdensome 
legacy rules to increase flexibility and encourage technical innovation 
to make NG911 services reliable, interoperable, and accessible to all.

DATES: 
    Effective date: Effective August 10, 2026.
    Compliance dates: Compliance will not be required for Sec. Sec.  
9.19(c)(1)(i) through (c)(3)(i) and 9.20(a)(1)(i), (a)(2)(i), and (b),

Synopsis

Introduction

    Today, we modernize the Commission's 911 reliability framework to 
reflect America's ongoing upgrade to modern high-speed 
telecommunications infrastructure. 911 Authorities are rapidly 
replacing legacy 911 systems and migrating to the Next Generation 911 
(NG911) ecosystem to gain access to advanced capabilities, enhanced 
resilience, greater interoperability, and improved accessibility.\1\ In 
this Second Report and Order (Order), we ensure the reliability of 
NG911 by leveraging the strengths of modern telecommunications 
networks, including high-capacity fiber, dynamic routing, automated 
monitoring, and real-time failover capabilities that do not exist in 
legacy systems.
---------------------------------------------------------------------------

    \1\ NG911 is an Internet Protocol (IP)-based system that enables 
emergency communications centers to receive, process, and analyze 
all types of 911 requests for emergency assistance; ensures 
interoperability; is secure; and meets certain other requirements. 
See 47 CFR 9.28.
---------------------------------------------------------------------------

    As the nation has embarked on the transition to NG911 over the last 
decade, the Commission has seen a corresponding increase in major, 
multi-state 911 service outages that have disrupted access to life-
saving emergency services for millions of Americans.\2\ Too often, 
these outages have occurred in parts of transitional NG911 systems 
outside the scope of the 911 reliability framework adopted in 2013,\3\ 
which does not address the increasingly complex array of call scenarios 
in the Internet Protocol (IP) call origination context we live in 
today. We believe that, in many of these instances, operators could 
have prevented or mitigated outages by implementing reliability 
measures appropriate for IP-based systems.\4\
---------------------------------------------------------------------------

    \2\ See, e.g., Facilitating Implementation of Next Generation 
911 Services (NG911), PS Docket Nos. 21-479 and 13-75, Further 
Notice of Proposed Rulemaking, 40 FCC Rcd 2668, 2676-77, para. 16 
(2025) (NG911 Reliability FNPRM).
    \3\ See Improving 911 Reliability; Reliability and Continuity of 
Communications Networks, Including Broadband Technologies, PS Docket 
Nos. 13-75 and 11-60, Report and Order, 28 FCC Rcd 17476 (2013) (911 
Reliability Order).

---------------------------------------------------------------------------

    Because the 2013 911 reliability framework cannot reliably support 
modern 911 call flows, we take the following actions to reduce the risk 
of future outages in transitional and end-state NG911 networks and to 
streamline and reduce the burdens of our approach:
     Covered 911 service providers. We update our definition of 
covered 911 service providers (CSPs) to identify categories of 
providers whose operations are essential to NG911 call delivery, whose 
failure could cause significant outages, and who therefore must meet 
enhanced reliability standards under the Commission's framework. Our 
updated CSP definition includes operators of Emergency Services IP 
networks (ESInets), Next Generation Core Services (NGCS) providers, and 
providers of real-time location services, major IP transport, IP 911 
traffic aggregation, and essential gateways for converting legacy and 
IP traffic.
     Reliability standards. We modernize and streamline the 911 
reliability benchmarks applicable to CSPs to reflect widely recognized 
best practices appropriate to IP-based 911 networks. These benchmarks 
incorporate well-established IP best practices in the areas of physical 
diversity, operational integrity, and network monitoring and reflect 
achievable standards identified by the Commission's Communications 
Security, Reliability, and Interoperability Council (CSRIC).\5\ We also 
make clear that CSPs can satisfy their reliability obligations by 
adopting reasonable alternative measures, including measures requested 
by state,

[[Page 42795]]

territorial, local, or tribal 911 Authorities.\6\
---------------------------------------------------------------------------

    \5\ CSRIC is a federal advisory committee that provides 
recommendations to the Commission on ways it can help ensure the 
security, reliability, and interoperability of communications 
systems. FCC, Communications Security, Reliability, and 
Interoperability Council, https://www.fcc.gov/about-fcc/advisory-committees/communications-security-reliability-and-interoperability-council-0 (last visited May 19, 2026).
    \6\ A 911 Authority is a ``State, territorial, regional, Tribal, 
or local governmental entity that operates or has administrative 
authority over all or any aspect of a communications network for the 
receipt of 911 traffic at NG911 Delivery Points and for the 
transmission of such traffic from that point to PSAPs.'' 47 CFR 
9.28. 911 Traffic is ``[t]ransmissions consisting of all 911 calls . 
. . and/or 911 text messages,'' as well as location information, 
callback numbers, and routing information sent with the call and/or 
text message. 47 CFR 9.28.
---------------------------------------------------------------------------

     Interoperability. To support the seamless transfer of 911 
calls and associated data across the NG911 ecosystem, we require NGCS 
and ESInet CSPs to report their recent actions to enable interstate 
NG911 interoperability, while seeking further comment on more detailed 
interoperability requirements. We also adopt a definition of 
``interoperability'' specific to NG911 to provide clarity for both CSPs 
and 911 Authorities as NG911 deployments progress.
     Certification Process. We eliminate the requirement that 
CSPs file annual compliance certifications and adopt a streamlined 
filing process for CSPs going forward. We provide for an 18-month 
transition period, after which CSPs will file initial reliability 
certifications in conformance with the new rules, which they will need 
to update only in the event of material changes. This will reduce 
unnecessary regulatory burdens on CSPs while focusing the certification 
process on essential information relevant to ensuring NG911 
reliability.
     Oversight. We allow 911 Authorities to access CSP 
certifications and reports subject to confidentiality safeguards, and 
we codify the process of the Public Safety and Homeland Security Bureau 
(PSHSB or the Bureau) for investigating and remediating noncompliance, 
providing transparency to service providers.\7\
---------------------------------------------------------------------------

    \7\ When outages do occur or are potentially imminent, the 
Commission imposes a distinct set of reporting, notification, and 
response requirements on various classes of service providers. See, 
e.g., 47 CFR 4.9(a)-(g), 4.11 (requiring cable, satellite, wireless, 
wireline, interconnected Voice over Internet Protocol (VoIP), and 
other providers to submit reports to the Commission if they 
experience significant outages on their networks), 4.9(h) (requiring 
these providers and CSPs to notify PSAPs that may be affected by 
significant outages), 4.17-4.18 (requiring certain providers to 
cooperate during disaster declarations and to submit status reports 
to the Commission). Nothing in this Order modifies those part 4 
rules; this Order strictly addresses the CSP reliability 
requirements in part 9 of the Commission's rules.
---------------------------------------------------------------------------

Background

The FCC's 911 Reliability Framework

    The Commission first required CSPs to improve the reliability and 
resiliency of 911 communications networks following an unanticipated 
and severe derecho storm in 2012. The storm struck the Midwest and Mid-
Atlantic regions of the United States, leaving millions of Americans 
without 911 service for up to several days.\8\ The Bureau conducted a 
comprehensive inquiry and found that the impacts to 911 service largely 
could have been mitigated or avoided had more providers adopted then-
current industry best practices for network reliability to protect 
their facilities.\9\
---------------------------------------------------------------------------

    \8\ FCC Public Safety and Homeland Security Bureau, Impact of 
the June 2012 Derecho on Communications Networks and Services: 
Report and Recommendations at 1 (2013) (Derecho Report), http://www.fcc.gov/document/derecho-report-and-recommendations. The effects 
were particularly severe in northern Virginia, where four PSAPs in 
the densely-populated National Capital Region lost service 
completely, and in West Virginia, where eleven PSAPs could not 
receive 911 calls for as long as twelve hours. Id. at 28-34.
    \9\ Id. at 1-2.
---------------------------------------------------------------------------

    1. In 2013, the Commission adopted rules requiring CSPs to 
implement these best practices and other sound engineering principles 
on their networks in order to prevent future 911 outages.\10\ At that 
time, most CSPs provided 911 functions and connectivity on the networks 
of Incumbent Local Exchange Carriers (ILECs) between legacy selective 
routers or location databases and PSAPs.\11\ The Commission defined 
CSPs to include entities that operate central offices directly serving 
PSAPs, as well as providers of 911, Enhanced 911 (E911), or NG911 
capabilities such as call routing, automatic location information 
(ALI), automatic number identification (ANI), or the functional 
equivalent of those capabilities.\12\ While recognizing the emergence 
of NG911, the Commission was not persuaded at that time ``that NG911 
technologies ha[d] evolved to the point that reliability certification 
rules should apply to entities beyond those that offer core services 
functionally equivalent to [legacy] 911 and E911 capabilities.'' \13\
---------------------------------------------------------------------------

    \10\ See 911 Reliability Order.
    \11\ 911 Reliability Order, 28 FCC Rcd at 17489, para. 37. A 
public safety answering point (PSAP) is ``[a]n answering point that 
has been designated to receive 911 calls and route them to emergency 
services personnel.'' 47 CFR 9.3.

    \13\ Id. at 17491, para. 42.
---------------------------------------------------------------------------

    The Commission required CSPs to annually certify their efforts to 
provide reliable 911 service with respect to circuit diversity, 
central-office backup power, and diverse network monitoring.\14\ 
Specifically, CSPs must make efforts to achieve the following goals:
---------------------------------------------------------------------------

    \14\ Id. at 17503-26, paras. 80-138.
---------------------------------------------------------------------------

     Circuit diversity: Eliminating all single points of 
failure in critical 911 circuits; tagging those circuits; and 
conducting diversity audits annually.\15\
---------------------------------------------------------------------------

    \15\ 47 CFR 9.19(c)(1).
---------------------------------------------------------------------------

     Central-office backup power: Provisioning central offices 
that serve PSAPs directly or that host selective routers with 
sufficient backup power to sustain full functionality in the event of 
power outages and testing and maintaining all backup power 
equipment.\16\
---------------------------------------------------------------------------

    \16\ Id. Sec.  9.19(c)(2).
---------------------------------------------------------------------------

     Network Monitoring: Implementing physically diverse 
network monitoring links and aggregation points where monitoring data 
are collected and conducting diversity audits of monitoring links and 
aggregation points annually.\17\
---------------------------------------------------------------------------

    \17\ Id. Sec.  9.19(c)(3).
---------------------------------------------------------------------------

    The Commission delegated oversight of the reliability rules and 
certification process to PSHSB. The Bureau established the 911 
Reliability Certification System (911RCS) to receive filings and 
certifications, and it was empowered to review certifications, revise 
certification forms and procedures, investigate noncompliance, and 
order remedial action.\18\
---------------------------------------------------------------------------

    \18\ Id. Sec.  0.392(j).
---------------------------------------------------------------------------

    Since adopting the reliability rules in 2013, the Commission has 
consistently observed that the rules would need to be updated to keep 
pace with the NG911 transition. For example, in a 2014 Policy Statement 
and Notice of Proposed Rulemaking on improving 911 governance, the 
Commission noted that it might need to update the rules to address 
changes in 911 technologies and the persistence of ``sunny day'' 911 
outages.\19\ And in 2015, the Commission reiterated its intent to 
consider ``whether [the rules] should be revised or expanded to cover 
new best practices or additional entities that provide NG911 
capabilities, or in light of our understanding about how NG911 networks 
may differ from legacy 911 service.'' \20\

(explaining further that providing CSPs with the flexibility to 
implement alternative measures was ``essential to support and 
encourage the transition to NG911,'' because the 2013 rules do not 
afford another option for most NG911 CSPs to demonstrate their 
reliability). See also 47 CFR 9.19(c)(1)(ii), 9.19(c)(2)(ii), 
9.19(c)(3)(ii) (If necessary, a CSP may certify that one or more of 
the reliability requirements does not apply to its network and 
provide a supporting explanation.).

---------------------------------------------------------------------------

[[Page 42796]]

    In July 2024, the Commission adopted a national NG911 transition 
framework that has accelerated the growth of the NG911 ecosystem.\21\ 
The new transition framework specifies a two-phased approach to guide 
the transition to NG911, in which 911 Authorities initiate each phase 
by submitting a valid request to originating service providers (OSPs) 
within the relevant jurisdiction, and OSPs must comply with NG911 
requirements for that phase within a defined period.\22\ In the NG911 
Transition Order, the Commission defined ``Next Generation 911'' to 
include interoperability, security, use of commonly accepted standards, 
and other criteria.\23\ It also noted the potential for NG911 to 
support improved reliability and interoperability and that some 
commenters had urged it to consider specific reliability and 
interoperability requirements.\24\ The Commission deferred 
consideration of reliability, interoperability, and accessibility \25\ 
proposals because at the time they were beyond the scope of the 
proceeding. The NG911 transition framework rules took effect in March 
2025,\26\ and since then, 911 Authorities have issued more than 190 
requests to begin Phase 1 service and one request for Phase 2 service. 
The requests cover parts or all of twenty-eight states and encompass 
more than 2,200 PSAPs.\27\

    2025 NG911 Reliability FNPRM. In March 2025, the Commission 
proposed to modernize the 911 reliability framework to better ensure 
the resiliency, reliability, interoperability, and accessibility of 
NG911 networks.\28\ In particular, the Commission proposed to expand 
the definition of covered 911 service providers so that IP-based 
providers and facilities that have emerged as essential to NG911 are 
subject to FCC reliability standards. The Commission proposed to 
clarify that it had already defined certain NG911 core services as CSPs 
under the 2013 reliability rules, because they provide NG911 
capabilities that are functionally equivalent to the call routing, 
automatic location information, and automatic number identification 
functions of covered legacy facilities.\29\

---------------------------------------------------------------------------

    The Commission proposed to update the three 911 reliability 
benchmarks (physical diversity, network monitoring, and backup power) 
that identify presumptively-reasonable measures to reflect sound, 
industry-standard network practices that support the reliability of 
modern NG911 networks.\30\ The proposed updated physical diversity 
benchmark included ensuring automatic rerouting capabilities, load 
balancing, and the geographic distribution of routing facilities, 
transport nodes, and node links sufficient to eliminate all single 
points of failure.\31\ The network monitoring proposal included 
monitoring critical NG911 facilities using geographically distributed 
automatic disruption detection and alarm mechanisms appropriate for IP 
systems.\32\ The Commission proposed to update the backup power 
benchmark by renaming it ``operational integrity'' and defining it to 
include providing location information server (LIS) and legacy network 
gateway (LNG) facilities with continuous power to maintain operations 
and the capability to automatically switch over to geographically 
diverse facilities.\33\ The Commission also proposed in the NG911 
Reliability FNPRM a new requirement for ESInets to be 
interoperable.\34\ Finally, the Commission proposed several reforms to 
its oversight of the CSP reliability certification process.\35\

---------------------------------------------------------------------------

Evolution of 911 Architecture

    Like telecommunications networks generally, 911 networks are 
evolving from Time-Division Multiplex (TDM)-based architectures to IP-
based architectures. As 911 Authorities transition to the NG911 
ecosystem, they must entirely replace the circuit-switched architecture 
of legacy 911 with IP-based technologies and applications that provide 
all of the same functions as the legacy 911 system, as well as new 
capabilities. In its end state, NG911 will facilitate interoperability 
and system resilience, improve connections between PSAPs, and support 
the transmission of text, photos, videos, and data to PSAPs by 
individuals seeking emergency assistance. Many 911 Authorities have 
made significant progress to implement the transition to NG911.\36\ As 
911 architectures evolve, the entities that support essential functions 
and control critical components and pathways on 911 networks also 
change. In considering the CSPs that must take reasonable measures to 
provide reliable 911 service, the Commission has monitored the changing 
roles and responsibilities of different entities within legacy, 
transitional, and NG911 network architectures.

NG911 expenditures in 2024 was $535,126,846.47. Id.
---------------------------------------------------------------------------

Legacy 911 Networks

    In 2013, when the Commission adopted the 911 Reliability Order, the 
legacy networks of incumbent wireline providers typically connected 
PSAPs to those seeking help, whether the call for assistance originated 
on a landline or a wireless phone.\37\ In these call flows, OSPs 
originate and transmit 911 calls placed by their customers, together 
with information about the callers' locations, to legacy 911 networks, 
where the calls are collected at an aggregation point called a 
selective router.\38\ The selective router identifies the appropriate 
PSAP to receive each call by accessing an internal routing table that 
compares the caller's location information to the service areas of 
local PSAPs. The routing table data are populated with the assistance 
of a Master Street Address Guide (MSAG), a database that stores all

[[Page 42797]]

valid physical addresses within each PSAP's service area, and an ANI/
ALI database that pairs provisioned phone numbers with MSAG addresses. 
After the selective router identifies the appropriate PSAP for each 
call, it determines the correct routing path for the call and transmits 
it, together with the caller's location and telephone number, to the 
central office serving the PSAP. Finally, the central office transmits 
the 911 call and associated caller information to the PSAP, typically 
along dedicated trunk lines. The PSAP validates the caller's location 
and callback number by querying ANI/ALI databases, and dispatches 
emergency services to the identified location.\39\

NG911 Networks

    As part of the broader IP transition, 911 Authorities are deploying 
new, IP-based NG911 networks to receive, process, and deliver 911 
traffic to PSAPs, and OSPs are changing how they transmit 911 traffic 
to those networks.\40\ At the core of NG911 networks are ESInets that 
receive and process 911 traffic from OSPs and forward that traffic to 
PSAPs. 911 traffic enters the ESInet at one or more points of 
interconnection (POIs). When 911 Authorities designate a POI under our 
NG911 transition framework, it is called an ``NG911 Delivery Point.''

    OSP IP infrastructure. To reach the POI, OSPs may connect directly 
in IP or convert their TDM legacy 911 voice traffic to an IP format 
using an LNG.\42\ In some cases, OSPs may contract with third parties 
providing high-capacity IP-based fiber networks to carry 911 traffic to

series of interconnected NG911 Core Services (NGCS) that collectively 
replace the caller location and routing functions of selective routers, 
ANI/ALI databases, and the MSAG in legacy 911 networks.\46\ These 
services typically include Location Validation Functions (LVFs), 
Emergency Call Routing Functions (ECRFs), and related technologies that 
enable the real-time provision of 911 caller location information to 
PSAPs (together, NGCS Location Facilities).\47\ The LVF is a server 
that validates civic location information against a Geographic 
Information System (GIS) database to deliver more dynamic and 
actionable information about a caller's location than legacy ALI/ANI 
databases can, and the ECRF is a database function that determines the 
appropriate destination PSAP by mapping the caller's validated location 
within the boundaries of emergency response zones.\48\ NGCS also 
include Emergency Services Routing Proxies (ESRPs), Policy Routing 
Functions (PRFs), and other technologies that enable the real-time 
routing, delivery, and transfer of 911 traffic to PSAPs along with 
callback information and other associated data (together, NGCS Routing 
Facilities).\49\ The ESRP is a routing engine that queries the ECRF and 
routes the traffic to the geographically appropriate PSAP in accordance 
with the PRF, which is the rule set that decides how traffic should be 
routed based on predetermined policies (e.g., priority levels, time of 
day, and load balancing).\50\

Transitional NG911 Networks

    While nationwide end-state NG911 remains the Commission's goal, it 
is necessary to recognize and accommodate intermediate architectures 
during the nationwide transition to NG911. The commonly-accepted 
transition path for NG911 envisions that NG911 will reach a mature 
``end state'' after all PSAPs have migrated from legacy E911 systems 
based on TDM circuit-switched telephony to all-IP systems that operate 
over ESInets and provide the full array of NGCS.\52\ Achieving end-
state NG911 will take time, and transitional NG911 networks need 
significant intermediate and transitional mechanisms in the interim. 
Transitional NG911 networks blend some legacy network components with 
IP-based infrastructure while the transition to end-state NG911 is 
still ongoing. Consequently, such deployments may retain selective 
routers, ANI/ALI, and other legacy elements as part of the call path 
even while implementing ESInets and NGCS. Transitional NG911 
deployments also typically include gateway facilities that translate 
911 traffic between TDM and IP formats as needed, including LNGs, 
emergency services gateways (ESGWs), legacy selective router gateways 
(LSRGs), and legacy PSAP gateways (LPGs).\53\

    In this Order, we modernize our 911 reliability framework for NG911 
networks.\54\ We seek to ensure that

[[Page 42798]]

entities essential to delivering emergency calls in the NG911 
environment implement common sense reliability measures to minimize 
risk of 911 outages, particularly catastrophic multi-state outages. To 
this end, we clarify and expand the CSP definition to identify which 
entities in the NG911 environment fall under the Commission's 911 
reliability framework; update the reliability standards to reflect the 
capabilities and architectures of IP networks; adopt a definition for 
interoperability specifically tailored to NG911; and improve oversight 
processes available to the Bureau and 911 Authorities. The purpose of 
these actions is to ensure the continued resiliency, reliability, 
interoperability, and accessibility of the NG911 ecosystem.
---------------------------------------------------------------------------

    \54\ In today's Order, ``NG911 networks'' refers to both 
transitional NG911 and end-state NG911 networks and ecosystems 
unless otherwise specified.
---------------------------------------------------------------------------

    Today's Order also eliminates the annual certification requirement 
for 911 reliability that the Commission imposed in 2013. Going forward, 
we establish a streamlined filing process in which CSPs will submit a 
one-time reliability certification subject to updates only in the event 
of material changes. This revised approach recalibrates our 911 
reliability framework to focus on critical aspects of the NG911 
transition while reducing regulatory burdens. The new certification 
process will allow CSPs to certify to reliability at the network level 
on a per-state basis and will no longer require submission of detailed 
site-based data for thousands of different facilities. These changes 
will substantially lighten the burden of previous compliance measures 
in place since 2013 and will enable providers to redirect those 
resources to implementing reliable networks for the transmission of 
NG911 traffic.\55\

Development of 911 Network Reliability Practices

    The required NG911 reliability practices we adopt today are based 
on two decades of investigations by the Commission into major network 
outages, studies and recommendations by federal advisory committees, 
rulemakings, and ongoing collaboration with industry stakeholders. For 
example, the Bureau found during its investigation into widespread 911 
outages caused by the 2012 derecho that several reliability measures 
available to NG911 networks--including IP routers with automatic fail-
over capability, diverse IP paths to PSAPs, interoperability between 
PSAPs, and diverse network monitoring--``likely could have 
significantly lessened the derecho's impact on emergency 
communications.'' \56\ In 2018, following its investigation into 
several major network outages, PSHSB identified increased monitoring of 
911 network components and faster failovers to redundant network 
equipment as key mitigating measures.\57\ And in 2020, following 
another series of major communications outages affecting 911, the 
Bureau encouraged CSPs to follow industry best practices for network 
reliability including circuit diversity and auditing, rerouting 
capabilities, and active network monitoring.\58\

    CSRIC regularly advises the Commission on ways to ensure the 
security, reliability, and interoperability of communications systems 
and to safeguard 911 service. In 2019, CSRIC VI provided 
recommendations to the Commission and to service providers concerning 
needed improvements to the reliability and resiliency of 911 systems 
during the transition to NG911.\59\ CSRIC based its report on 
information from a wide variety of sources, including industry subject 
matter experts, 911 Authorities, public safety groups, CSRIC best 
practices and other CSRIC efforts, industry documents related to NG911 
reliability, and FCC reports.\60\ CSRIC recommended, for example, that 
service providers monitor for events that could result in a loss of 
service; \61\ incorporate network monitoring tools on originating and 
transport networks specifically, to protect 911 traffic before it 
reaches the ESInet perimeter; \62\ and work with stakeholders to share 
monitoring information.\63\ CSRIC's updated best practices for NG911 
included: geographic separation of network redundancy facilities; 
configuring backup power at critical sites to auto-engage in the event 
of a failover; development of standards for network interconnections; 
securing transport over the public internet with authentication and 
confidentiality mechanisms such as digital signatures and Virtual 
Private Network (VPN) tunneling; logical diversity for NG911 signaling 
networks, confirmed with regular diversity audits; dedicated, geo-
diverse, and redundant IP connection points; geographically diverse 911 
location servers; functional redundancy and geographic diversity for 
critical network elements; physical and geographic redundancy for 
critical facilities links; diverse routing from OSPs to the ESInet; and 
redundant connectivity from the ESInet to PSAPs.\64\

911 systems are highly interconnected and that interoperability between 
call-taking and call processing components is critical.\66\ CSRIC

dependent on the degree of progress made by state and local 911 
authorities in transitioning their respective systems to mature or end-
state NG911 capability.\67\ CSRIC

identified interoperability challenges and indicators of successful

transition ranging from legacy state, through foundational, 
transitional, and intermediate states, culminating in the 
jurisdictional and nation-wide ``end state'' of NG9-1-1 service. Per 
TFOPA, ``End State'' refers to the state in which PSAPs have evolved 
to become emergency communications centers (ECCs) and are served by 
standards-based NG911 systems and/or elements and OSPs are providing 
SIP interfaces with location information during call setup, and 
ESInets are interconnected providing interoperability on a national 
basis, supported by established agreements, policies and procedures.

The Need for Changes to the 911 Reliability Framework

    NG911 provides significant advantages over legacy 911 systems, 
including enhanced reliability, redundancy, interoperability, and 
accessibility. However, without robust design, NG911 networks can 
heighten the risk to the public of widespread outages due to their 
increased aggregation and consolidation of traffic. In contrast to 
legacy 911 networks, in which call origination, routing, and delivery 
occur locally and are managed by a small set of providers, the NG911 
ecosystem typically aggregates traffic from OSPs across broad 
geographic regions, transports this traffic over long distances, and 
relies on multiple operators. This aggregation makes the NG911 
ecosystem more capable and flexible but also larger and more complex 
than the legacy ecosystem, with higher traffic volumes carried over 
longer transport paths than in legacy networks. Additionally, as noted 
above, the transitional NG911 ecosystem depends on functional elements 
that translate 911 calls between TDM and IP formats--elements often 
located far from the point where calls originate or are handed off to 
ESInets and PSAPs. The risks posed by substandard implementation of 
this new network architecture are not theoretical, as evidenced by 
recent 911 outages attributable to vulnerabilities in heretofore 
unregulated network elements.\69\ As NG911 deployment accelerates, 
close coordination between industry, public safety entities, 911 
Authorities, and the Commission is essential to ensure against 
vulnerabilities that could undermine 911 reliability, resiliency, and 
accessibility.
---------------------------------------------------------------------------

    \69\ See, e.g., New York Public Service Commission (NYPSC) 
Comments at 2 (attesting to widespread 911 outages in New York 
originating in major transport networks that ``took significantly 
longer to identify and understand'' because the networks were not 
covered by the 911 reliability rules); NENA Comments at 1-2

the [ESInet]'' have been the cause for ``several states that have

Authorities, Inc. (CCOA) Comments at 2 (stating that unregulated 
``aggregators and operators of high-capacity transport facilities'' 
have been the source of recent vulnerabilities, which ``disrupts 
critical 911 functions and impacts multiple'' PSAPs); Colorado

---------------------------------------------------------------------------

    Alongside the broader IP transition, the emergence of NG911 has 
given rise to new classes of service providers that did not exist in 
legacy 911 networks but play essential roles in the NG911 ecosystem's 
call path. These new provider classes include third-party transport 
providers retained by OSPs to carry 911 traffic over high-capacity 
fiber networks; specialized entities that aggregate 911-only traffic 
for transport and delivery; and providers of IP-based signaling 
translation functions.\70\ NG911 network providers frequently engage 
third-party operators to manage servers and other critical facilities 
supporting 911 call routing and other key functions across multiple 
states and jurisdictions.\71\ Some of these new providers are not 
covered by the Commission's previous 911 reliability rules, despite 
their essential and expanding role in maintaining the continuity of 911 
service.\72\ Other NG911 capabilities fall within the category of 
``functional equivalents'' under the prior rules, yet, as we detail 
below, the record demonstrates that many new providers of these 
capabilities have not recognized that the prior rules apply to them. 
Moreover, the prior reliability rules are inherently static, such that 
tethering NG911 ``functional equivalents'' to the legacy environment 
does not allow the rules to scale effectively to accommodate the 
continued evolution of IP-based NG911 call-originating technologies and 
exchanges of information. Without clarifying the 911 reliability 
framework to expressly cover all critical NG911 providers and 
functions, the Commission cannot effectively address or mitigate the 
risks of significant outages on IP-based and NG911 networks.\73\

    As the Commission observed in the NG911 Reliability FNPRM, the 
landscape of 911 outage risk has evolved significantly since 2013. The 
FNPRM specifically cited examples of major 911 outages affecting 
millions of Americans in multiple states as 911 Authorities seek to 
transition from legacy 911 to NG911.\74\ Moreover, since the release of 
the FNPRM, additional 911 outages have occurred in Pennsylvania, 
Mississippi, Louisiana, Alabama, Wyoming, and Montana, highlighting 
continued vulnerabilities that can affect statewide and multi-state 
NG911 deployments.\75\ Some of these outages were triggered by single 
fiber cuts, which indicates that NG911 networks have not yet 
consistently implemented the geographically-distributed reliability 
measures we adopt in our Order today. Several failures originated in 
portions of the NG911 call flow located downstream of originating 
providers' owned-and-operated networks but upstream of ESInet and NGCS 
elements covered as ``functional equivalents'' under the 2013 
reliability rules.\76\ Failures in these

[[Page 42800]]

uncovered transport and aggregation segments can interrupt 911 service 
to dozens or hundreds of PSAPs, yet, to date, both the Commission and 
911 Authorities have lacked visibility into the reliability practices 
employed by providers operating in this segment.\77\ Without remedial 
action, these vulnerabilities could contribute to the continued 
occurrence of major ``sunny day'' 911 outages.\78\

the Commission's NG911 transition framework, OSPs also have the 
obligation to deliver 911 traffic to the NG911 delivery point, which 
is a logical demarcation dividing the responsibilities of OSPs and 
911 Authorities for the delivery of 911 traffic. See 47 CFR 9.29,

changes in 911 technologies and the persistence of ``sunny day'' 911 
outages).
---------------------------------------------------------------------------

    The framework we adopt today is narrowly tailored to strengthen 
NG911 networks while eliminating unnecessary regulatory burdens. By 
eliminating the requirement that CSPs file annual certifications and 
replacing it with a streamlined certification process, we maintain 
accountability while reducing the administrative burden on CSPs. We 
further align this streamlined regulatory oversight with the actual 
flow of 911 traffic in NG911 networks to ensure the rules remain 
appropriately limited to demonstrated areas of vulnerability. Our 
updated definition of ``covered 911 service provider'' focuses on those 
entities that play essential roles in routing, validating, or 
transporting 911 traffic in real time and whose failure would pose the 
most significant risk to service availability. Our updated reliability 
benchmarks address the principal vulnerabilities in NG911 architecture 
without imposing unnecessary or overly prescriptive requirements on 
CSPs. These benchmarks incorporate reliability measures recommended by 
CSRIC and recognized in the record as prevailing best practices, while 
also leveraging the inherent strengths of IP-based systems to adapt and 
self-heal in real time.\79\ The new framework will optimize NG911 to 
meet operational needs today and tomorrow and ensure that actionable 
location and call back information and other data reliably move from 
callers to PSAPs and enable PSAPs to dispatch emergency responders 
quickly and effectively.

reliability framework now, while the NG911 transition is still in a 
relatively formative phase, rather than waiting for further NG911 
deployments or full completion of the transition.\80\ We agree with 911 
Authorities, national public safety organizations, and some OSPs that 
an orderly transition to the NG911 ecosystem requires prompt updating 
of the definition of CSPs and the 911 reliability standards.\81\ We 
disagree with industry commenters who argue that such action is 
premature.\82\ We conclude that waiting until the transition is 
completed to see what problems remain to be addressed ignores 
demonstrated risks to 911 reliability and needlessly delays 
implementation of available solutions.\83\ The stakeholder community 
has already developed detailed and well-established technical 
architecture and commonly accepted standards for NG911 systems,\84\ and 
the reliability framework we adopt today is based on well-documented 
best practices for IP networks that can readily be implemented by CSPs 
as part of their network build-outs.

    Concurrently, many 911 Authorities have initiated the 
implementation of NG911 functional elements, made substantial 
investments in NG911 systems (spending over $500 million on NG911 
programs in 2024 alone),\85\ and submitted valid requests for NG911 
service covering a significant portion of the United States. These 
collective efforts demonstrate that the NG911 ecosystem has reached a 
level of maturity where uniform expectations for reliability are both 
feasible and necessary. These efforts have also provided us with ample 
guidance to modernize the reliability framework in a way that reflects 
current operational realities and keeps pace with the fast-moving 
technological evolution of the capabilities inherent in IP-based 
networks. Adopting an updated framework now ensures that NG911 networks 
will be designed according to reasonable reliability standards from the 
outset and avoids the need for inefficient and costly retrofits in the 
future.\86\ Early action also provides 911 Authorities with tools to 
engage in appropriate oversight of newly deployed NG911 services, 
enabling more effective planning and management of subsequent system 
performance and resiliency.\87\ We revise our oversight framework in a 
streamlined manner, ensuring transparency and accountability while 
minimizing burdens and protecting sensitive operational information. In 
addition, we are providing an 18-month transition period for 
implementation of the new framework to afford CSPs time to integrate 
the updated reliability benchmarks into their ongoing NG911 deployments 
and to refine their networks, operations, and reliability practices 
accordingly. These actions reaffirm our commitment to ensuring that 911 
remains dependable, resilient, and available when Americans need it 
most.

911 Reliability

Covered 911 Service Providers

    As proposed in the NG911 Reliability FNPRM, we update the 
definition of

[[Page 42801]]

``covered 911 service provider'' to accurately reflect the modern NG911 
ecosystem and ensure that providers of critical NG911 services design 
their networks to safeguard 911 traffic.\88\ We preserve the 
reliability requirements for legacy covered 911 services while more 
specifically defining the NG911 routing and location capabilities 
covered as part of this definition. We do this by clarifying that NGCS 
that provide NG911 location and routing capabilities are the 
``functional equivalent'' of legacy selective routing and ANI/ALI 
services. We also expand the covered 911 services definition to include 
transport and aggregation facilities carrying substantial 911 traffic 
from two or more OSPs as well as some other shared facilities. These 
actions ensure that the term ``covered 911 service provider'' 
encompasses entities providing 911, E911, or NG911 services for which a 
failure would impede the real-time routing, delivery, or transfer of 
911 traffic.\89\

---------------------------------------------------------------------------

    While the transition to NG911 is progressing alongside broader IP 
modernization, 911 Authorities and OSPs will continue for some time to 
rely on legacy selective routers and other TDM-based infrastructure for 
delivery of 911 calls to PSAPs.\90\ In transitional NG911 systems, 
these legacy 911 network elements (selective routers; ANI/ALI 
databases; and TDM 911 circuits between selective routers, ALI/ANI 
databases, and the last central office serving a PSAP) will be treated 
as covered 911 facilities as they were under the 2013 reliability 
rules.\91\ NGCS facilities and ESInet IP paths to PSAPs will also be 
covered 911 facilities, as will ESInet paths between NG911 delivery 
points and NGCS facilities. The definition of covered 911 services 
includes operation of NG911 and transitional elements serving two or 
more OSPs, such as LNGs, ESGWs, LSRGs, LISs, and LPGs.

and 25-208, Report and Order, FCC 26-19, 2026 WL 1016892 (Mar. 27, 
2026). The Commission's goal during this period is to encourage the 
development and deployment of advanced IP networks and services, 
including NG911, while ensuring seamless 911 connectivity. Id. at 
*25, para. 69. To that end, among other protections, the Commission 
requires carriers seeking to discontinue services supporting 
interconnection trunks or exchange of traffic to provide impacted 
911 Authorities, 911 service providers defined as an entity that 
provides 911, E911, or NG911 capabilities or the functional 
equivalent of those capabilities directly to a PSAP, and directly 
interconnecting local exchange service providers that support 
essential functions within 911 networks with advance notice and a 
point of contact with which to coordinate an orderly transition away 
from legacy facilities that support 911. Id. at *24-25, paras. 67, 
69 (``[W]e expect that carriers and service providers will engage in

    \91\ Appendix B provides three illustrative network diagrams 
that demonstrate the application of our updated 911 reliability 
framework for legacy and transitional environments as well as for 
more mature NG911 configurations. The diagrams include an overlay of 
the presumptive cost allocation between OSPs and 911. Historically, 
the Commission has found that OSPs should bear the costs associated 
with transmitting legacy 911 calls from their end users to the 
points where they hand off such calls to selective routers used to 
transmit those calls to appropriate PSAPs. NG911 Transition Order, 
39 FCC Rcd at 8202-03, para. 146 (citing Revision of the 
Commission's Rules to Ensure Compatibility with Enhanced 911 
Emergency Calling Systems; Request of King County, Washington, CC 
Docket No. 94-102, Order on Reconsideration, 17 FCC Rcd 14789 
(2002)). Under the Commission's NG911 transition framework, OSPs 
similarly are financially responsible for the costs of transmitting 
911 traffic from their end users to NG911 Delivery Points, in the 
absence of an alternative cost arrangement with the relevant 911 
Authority. Id. at 8201-06, paras. 145-153.
---------------------------------------------------------------------------

    In more mature NG911 systems, in which the selective router, legacy 
ANI/ALI facilities, and covered 911 TDM circuits connecting selective 
routers are no longer part of the call flow, the updated definition of 
covered 911 services includes ESInets, NGCS facilities, and ESInet IP 
covered 911 paths, as well as NGCS routing and location facilities such 
as the ESRP, PRF, ECRF, and LVF.\92\ Covered 911 services also include 
several multi-OSP services, including IP 911 traffic aggregation, major 
IP transport, and shared LIS and LNG facilities.\93\

    Technologically neutral regulation of 911 reliability. 
Historically, the Commission has allowed providers to use various 
proven technologies and approaches to comply with 911 reliability rules 
rather than prescribing specific solutions.\94\ We reaffirm this 
commitment to a technologically neutral approach for regulating covered 
911 providers in order to ``future-proof'' our framework, an approach 
that is strongly supported by commenters in this proceeding and will 
provide regulated entities compliance flexibility. Consistent with this 
principle, we define a CSP as any entity that provides covered 911 
services, which are 911, E911, or NG911 services for which a failure 
would impede the real-time routing, delivery, or transfer of 911 
traffic.\95\ This definition uses informative, non-normative 
examples,\96\ with reference to functional elements featured in current 
commonly accepted NG911 standards, in order to clearly delineate the 
types of services that are critical to 911 reliability today. Our 
technologically-neutral approach also serves to ensure that we do not 
``inadvertently stifle innovation, create misalignment with standards-
based implementations, or sweep in entities whose operations do not 
materially impact the delivery of emergency services.'' \97\ We believe 
that our approach is flexible enough to not only ensure clear 
compliance today but also to guide future compliance as technologies 
change.

    Preserving State and Local Government Flexibility. Today's action 
leaves in place the exemption for state and local governments operating 
their own facilities that would otherwise be covered 911 services. 
Thus, no PSAP, 911 Authority, or other governmental authority directly 
providing 911, E911, or NG911 capabilities is a CSP or is otherwise 
subject to these regulations.\98\ Further, we emphasize that we do not 
preclude states from adopting their own 911 reliability approaches that 
do not conflict with the Commission's goals in this proceeding, for 
example, by adopting reliability measures for smaller transport 
facilities than those we regulate today.\99\ In addition, for CSPs that 
directly serve 911 Authorities, today's framework leaves in place the 
ability to implement alternative reliability measures to mitigate the 
risk of failure in certain situations, taking

[[Page 42802]]

into account the level of service ordered by the PSAP or 911 
Authority.\100\
---------------------------------------------------------------------------

    \98\ We make non-substantive, clarifying edits to the language 
in section 9.19(a)(4)(ii) setting forth this exemption. The revised 
rule now specifies that 911 Authorities are exempt governmental 
authorities and that the 911 capabilities that are exempted include 
E911 and NG911 capabilities. Appendix A (Sec.  9.19(a)(4)(ii)(A)).

ordinances).''). See also id. at 17504, 17510, paras. 83, 98.
---------------------------------------------------------------------------

    Applicability to OSPs. The Commission requires OSPs--by which we 
generally mean entities that offer end users the ability to originate 
911 calls--to transmit such calls with appropriate location information 
to a PSAP, to a designated statewide default answering point, or to an 
appropriate local emergency authority.\101\ As part of the NG911 
transition framework, the Commission also requires OSPs to deliver all 
911 traffic to NG911 Delivery Points following the receipt of a valid 
request from a 911 Authority for Phase 1 or 2 service.\102\ This Order 
does not alter the scope or applicability of such OSP requirements, nor 
does it apply 911 CSP reliability requirements to OSPs. However, as 
discussed below, we revise the 911 reliability framework to address 
third-party transport and aggregation of 911 traffic from OSPs to NG911 
delivery points.
---------------------------------------------------------------------------

    \101\ We call the relevant provisions at sections 9.4, 9.8, 
9.10, 9.11, 9.14, and 9.18 the ``911 transmission rules'' in this 
Order. See 47 CFR 9.4 (requiring telecommunications providers to 
transmit all 911 calls to a PSAP, designated statewide default 
answering point, or appropriate local emergency authority; rule does 
not address transmission of location information); 47 CFR 9.8

    \102\ See 47 CFR 9.28 (defining OSPs); 47 CFR 9.29(a), (b) 
(NG911 delivery rules).
---------------------------------------------------------------------------

    The 911 transmission rules already in place are distinct from the 
measures to support 911 reliability that we adopt today. As an initial 
matter, the 911 transmission rules and the 911 reliability framework 
apply to two different classes of providers. The 911 transmission rules 
apply to telecommunications carriers and certain other providers that 
originate 911 traffic, i.e., OSPs. CSPs, on the other hand, provide 
911, E911, or NG911 capabilities that do not include call 
origination.\103\ Originators of 911 calls have been explicitly 
excluded from the 911 reliability framework where another service 
provider, typically a CSP, transmits the calls to a PSAP.\104\ We 
maintain this exemption while updating it to reflect the reality that, 
in NG911 networks, 911 traffic is delivered to 911 Authorities at their 
ESInet POI.\105\ However, to fulfill their transmission obligations 
under our rules, OSPs frequently contract with third parties to pick up 
911 traffic from their networks and transport it to 911 Authorities' 
911 networks.\106\ Under the framework adopted in this Order, some of 
these third parties--specifically major IP transport providers and IP 
911 traffic aggregators--will now be CSPs.

    Some commenters contend that extending the scope of the CSP 
requirements to entities that contract with OSPs creates a substantial 
new regulatory burden without a corresponding benefit to 911 
systems.\107\ We disagree. It is reasonable to assume that OSPs already 
consider, when selecting transport and aggregation vendors, whether 
those vendors have implemented reasonable reliability measures in order 
to support their 911 transmission obligations.\108\ Today, we add an 
additional level of assurance for OSPs if they select an entity 
providing major IP transport or IP 911 traffic aggregation services, 
because our new framework now requires these entities to implement 
basic resiliency and reliability measures. Since these new types of 
CSPs consolidate enough 911 traffic that an outage affecting them would 
severely impact the availability of 911 services to the public, 
ensuring that these entities implement basic reliability measures is a 
reasonable step. Additionally, extending reliability requirements to 
these new types of CSPs supports the ability of OSPs to fulfill their 
911 transmission obligations.

    For these reasons, we disagree with comments contending that our 
amendments to section 9.19 will duplicate obligations that OSPs already 
have under the 911 transmission rules and that the 911 transmission 
rules are sufficient to ensure reliability on the OSP side of the NG911 
call path.\109\ In reality, our updated reliability framework empowers 
the Commission to apply its 911 oversight authority preventatively to 
facilities instead of after an outage when transmission rule violations 
have already occurred. Moreover, as discussed in greater detail below, 
we have addressed these commenters' concerns by adjusting the proposed 
definitions of the newly-covered CSP facilities so that they apply 
exclusively to high-volume, third-party services provided to two or 
more OSPs and not to transmission capabilities that OSPs provide via 
their own networks. Far from imposing duplicative burdens on OSPs, our 
amendments to section 9.19 provide greater certainty for OSPs that 
contract with third-party CSPs to provide 911 transport or delivery 
services. OSPs will now be able to easily assess the reliability of 
these service providers based on their implementation of the 
Commission's requirement to provide reasonably reliable 911 services.

---------------------------------------------------------------------------

    NG911 cost allocation. In legacy 911 networks, ILECs operate most 
or all of the network infrastructure used to route and deliver 911 
calls to PSAPs under tariff or contractual agreement with

[[Page 42803]]

PSAPs and emergency authorities.\110\ When the Commission adopted the 
2013 reliability rules, these tariff and contractual arrangements were 
well-established, so the Commission did not address cost issues at that 
time. Instead, the Commission focused on enhancing the reliability of 
the 911 capabilities being provided through these relationships.\111\ 
When the Commission established its NG911 Transition framework in 2024, 
it found it necessary to expressly allocate NG911 costs between OSPs 
and 911 Authorities, because uncertainty and disagreements over the 
basic terms on which OSPs would begin to provide NG911 service were 
delaying the nationwide transition to NG911.\112\ Under the NG911 
Transition framework, OSPs are presumptively responsible for the costs 
of translating 911 traffic into SIP format and the costs of delivering 
911 traffic and associated routing and location information to the 
NG911 Delivery Points designated by 911 Authorities.\113\ In other 
words, OSPs are ``responsible for the costs of complying with their own 
911 service obligations,'' \114\ while 911 Authorities bear the costs 
incurred beyond NG911 Delivery points to process and transmit 911 
traffic to the appropriate PSAP.\115\ OSPs and 911 Authorities may, 
however, modify these default cost allocations by mutual 
agreement.\116\

    As the national transition to IP-based telecommunications has 
advanced and NG911 network architectures have evolved, the array of 
entities providing 911 capabilities has become more complex. The 
contractual arrangements through which NG911 service is provided have 
become more complex as well. For example, we identify today several new 
classes of IP-based CSPs that have become essential to the routing and 
delivery of 911 traffic in the NG911 environment. Among them are CSPs 
that provide processing and transport of 911 traffic from OSPs' 
networks to NG911 Delivery Points or ESInet POIs. These entities often 
have contractual relationships with OSPs rather than direct 
relationships with PSAPs or 911 Authorities. Several commenters 
question which entities should bear the costs of newly designated CSP 
services in the NG911 environment.\117\ We therefore clarify that 
nothing in this Order changes the default cost allocation the 
Commission adopted in the NG911 Transition Order. OSPs remain 
presumptively responsible for costs of delivery to the NG911 Delivery 
Point or other ESInet POI, regardless of whether they deliver traffic 
entirely over their own networks or hire third-party CSPs to provide 
intermediate transport and/or aggregation.\118\ 911 Authorities remain 
presumptively responsible for completing 911 calls after they are 
handed off at the NG911 Delivery Point and therefore bear the costs of 
ESInets, NGCS, and other NG911-related CSP services beyond that 
point.\119\ We emphasize, however, that the framework's division of

NG911 Functional Equivalents

    As proposed in the NG911 Reliability FNPRM, we define NG911 
location and routing capabilities that are part of NGCS as covered 911 
services because they are the functional equivalents of legacy 
selective routing and ANI/ALI services that were identified as covered 
services under the original CSP definition.\121\ The Commission adopted 
the ``functional equivalent'' language in 2013 to ensure that the CSP 
definition would be flexible enough to capture emerging NG911 entities 
while avoiding overbroad regulation.\122\ While this approach has been 
effective to a degree, the recent acceleration of the NG911 transition 
requires us to provide additional clarity to aid in compliance with 911 
reliability framework. NENA points out that some companies operating 
critical NG911 facilities have argued the ``functional equivalent'' 
language in the 2013 rules does not include their facilities, and so no 
specific reliability measures are required.\123\ CCOA also cites a 
service provider that has argued the original circuit diversity rules 
only apply to circuits from routing facilities in central offices and 
not to critical circuits elsewhere in the 911 call path.\124\
---------------------------------------------------------------------------

    \121\ 47 CFR 9.19(a)(4)(i)(A) (CSPs are entities that provide 
911 call routing or location information ``or the functional 
equivalent of those capabilities.'').

---------------------------------------------------------------------------

    To address these concerns, we reference specific NGCS location and 
routing functions to make the updated 911 reliability framework clearly 
applicable to critical NGCS services and facilities.\125\ We define 
NGCS location facilities as functional elements connected to an ESInet 
that enable the real-time provision of 911 caller location information 
to PSAPs, including but not limited to the LVF, the ECRF, and successor 
technologies. We define NGCS routing facilities as functional elements 
connected to an ESInet that enable the real-time routing, delivery, or 
transfer of 911 traffic to PSAPs along with callback information and 
other associated data, including but not limited to the ESRP, the PRF, 
and successor technologies.\126\ We emphasize that these listed NGCS 
elements are merely examples of transitional and future technologies 
performing routing and location functions, and are not intended to be 
exclusive.

at 1. But see NENA Comments at 5 (stating the PRF should be 
integrated with the ESRP and need not be listed). We include the PRF 
in light of the comment record reflecting variations in how NGCS 
systems are being deployed. Compare NENA Comments at 4, with iCERT 
Comments at 9 (disagreeing whether the LVF requires reliability in 
NGCS configurations); compare NENA Comments at 5-6, with iCERT 
Comments at 10 (disagreeing whether the MSAG Conversion Service, 
GeoCode Service, and Mapping Data Service functional elements 
require reliability in NGCS configurations).
---------------------------------------------------------------------------

    We provide these clarifications because NG911 systems process 
routing and location information differently than legacy 911 systems. 
For example, the caller location function in NG911 does not rely on 
legacy ANI/ALI databases or MSAGs \127\ to perform live-call location; 
instead, the LIS and LVF supply location data to other 911

[[Page 42804]]

functional elements through periodic updates typically.\128\ As iCERT 
explains, while the LIS is functionally equivalent to legacy ALI/ANI 
databases and the LVF is functionally equivalent to the MSAG, the LVF 
may perform live-call critical functions in NG911 of validating 
location addresses as a 911 call is made.\129\ As such, the prior rule 
does not perfectly correlate critical NG911 location and routing 
elements to their ``functionally equivalent'' legacy 911 service in 
every instance.\130\

    We agree with commenters that suggest we include LVF and similar 
location validation functional elements as examples of covered NGCS 
functional elements, but only when used in live-call processing.\131\ 
This modification addresses variation in how NGCS providers configure 
the LVF to interface with other functional elements.\132\ If an NGCS 
provider is using its location validation facilities for real-time 
location queries, those facilities are subject to our 911 reliability 
framework. If a NGCS provider has chosen to arrange its system so that 
its location validation facilities only periodically send information 
to a LIS or other NGCS element, then the LVF is being used more like 
the GIS, and thus there is no need to include it as a covered 911 
facility.
---------------------------------------------------------------------------

    \131\ See, e.g., NASNA Comments at 2 (urging the exclusion of 
GIS as an NGCS Location Facility due to its ``distance from the real 
time call flow'' and acknowledging that an LVF can replicate legacy 
ALI/ANI real time location functionality); iCERT Comments at 9 (LVF 
``utilize[s] GIS information and data that are critical to the real-
time routing and delivery of 911 calls within an NG911 
environment''); Intrado Comments at 15 (Capabilities should not be 
covered if they are ``outside the call flow and [are] not directly 
related to real-time call routing or transmission of caller location 
information.'').
    \132\ NENA Comments at 4; iCERT Comments at 9.
---------------------------------------------------------------------------

    In addition to the LVF, we include the ECRF as an example of 
covered live-call NGCS location facilities, and the ESRP and the PRF as 
examples of covered live-call NGCS routing facilities. While we provide 
these specific examples, we also retain the ``functional equivalent'' 
language from the prior rule to capture both transitional NG911 
elements and future technologies that may be developed to perform NGCS 
functions. As NASNA notes, including transitional routing and location 
functional elements as covered 911 facilities is important to ensure 
transitional 911 systems remain reliable.\133\ For example, IP 
selective routers and IP ALI databases are examples of transitional 
architecture that may perform basic IP routing and location functions 
at an ESInet before a 911 Authority has built and deployed full NGCS 
routing and location capabilities.\134\

    Some commenters question whether certain NGCS elements--such as 
MSAG Conversion Service, GeoCode Service, and Mapping Data Service--are 
needed for 911 live-call routing or location information.\135\ The 
functional definition we adopt today resolves the issue by including 
these functions only when the NGCS provider uses them for live-call 
routing or location information. We also agree with NENA and other 
commenters that recommend against including GIS as an example of 
covered NGCS Location Facilities. GIS is a ``a system for capturing, 
storing, displaying, analyzing, and managing data and associated 
attributes which are spatially referenced'' to map and visualize data 
such as the locations of streets and buildings.\136\ While GIS plays an 
important role in NG911, we exclude it because it is not used for the 
delivery of real-time 911 caller location information. Instead, GIS is 
a data resource that supplies information to a LIS or NGCS element only 
periodically so that those covered elements can perform the live caller 
location function.\137\

    Direct Service to 911 Authorities. As proposed in the NG911 
Reliability FNPRM, we require providers of NGCS covered 911 services to 
comply with the 911 reliability framework when providing such services 
directly, by contract or tariff, to a 911 Authority, whether via owned 
and operated facilities or leased or contracted facilities.\138\ While 
some commenters support extending reliability requirements for NGCS 
functional elements to services provided indirectly as well as directly 
to 911 Authorities, we are persuaded by commenters who argue that the 
Commission should avoid adopting overbroad regulations that could 
increase 911 Authorities' and PSAPs' costs.\139\ We agree with NASNA 
that CSP obligations should fall on the NGCS ``primary provider'' in a 
jurisdiction, instead of on every NGCS subcontractor.\140\ We also 
agree with APCO and other commenters that direct regulation of NGCS 
subcontractors is excessive and unnecessary, because the CSP providing 
direct service is best positioned to ensure reliability and because 
direct regulation of a CSP's third-party contractors could 
unnecessarily increase costs.\141\ We therefore decline to follow the 
suggestion of NENA and other commenters asking to directly cover any 
NGCS routing and location service subcontractor regardless of its 
relationship to 911 Authorities.\142\ However, as discussed in more 
detail below, we apply the 911 reliability framework independently to a 
narrow subset of critical NG911 facilities (ESInets and associated 
transitional gateways) that may be provided by the NGCS provider or its 
subcontractors.

    Administrative Lines. Some commenters advocate revisions to

[[Page 42805]]

remove administrative lines from the definition of essential facilities 
to be maintained by legacy CSPs.\145\ We decline to revise the legacy 
911 reliability definition at this time, because TDM-based 
administrative lines continue to be used in legacy PSAPs as a backup 
option during outages as well as for PSAP-to-PSAP calls.\146\ However, 
we anticipate that this requirement will become moot as legacy PSAPs 
replace TDM administrative lines with VoIP connectivity delivered by 
ESInets.\147\ Accordingly, we encourage 911 Authorities, PSAPs, CSPs, 
and OSPs to work together to quickly migrate and retire legacy TDM 
facilities consistent with the overall goals of the NG911 transition 
and the IP transition. As the NG911 transition progresses, the 
Commission may re-evaluate the continued importance of reliability 
requirements for legacy administrative lines.

ESInets and Legacy PSAP Gateways

    As proposed in the NG911 Reliability FNPRM, we designate the 
operation of ESInets, as covered 911 services subject to our 911 
reliability framework.\148\ The Commission has historically treated 
ESInet providers as CSPs to the extent they provide covered 911 
services.\149\ The Commission has also recognized that ESInet paths to 
PSAPs are ``critical 911 circuits'' under the 2013 rules.\150\ The 
NG911 Reliability FNPRM proposed to explicitly identify ESInet 
transport paths to PSAPs as covered facilities.\151\ We adopt this 
proposal in today's Order, affirming that operation of an ESInet is a 
covered 911 service. This recognizes the fact that ESInet operators 
typically manage critical NG911 circuits and paths needed to receive 
and process 911 calls from OSPs and transmit them to 911 
telecommunicators, forming the ``backbone'' of NG911.\152\ As a 
practical matter, identifying ESInet operators as CSPs is not a major 
rule change, because most current ESInet operators have already filed 
911 reliability certifications under the prior rules.

    Because of the central and critical role of transport performed by 
ESInets in the NG911 ecosystem, we classify all ESInet providers as 
CSPs regardless of whether they provide services directly or indirectly 
to a 911 Authority. As NENA notes, there may be instances where a 
regulation covering NGCS providers ``directly serving'' a 911 Authority 
may not capture corresponding ESInet providers, as the two entities 
might be separate with only one of the two having a contract with the 
911 Authority.\153\ To accommodate potential variation in state and 
local government NG911 deployments and ensure that all ESInets meet 
reliability standards, we include the operation of an ESInet as a 
covered 911 service whether the service is provided directly or 
indirectly to 911 Authorities.

transitional elements, which link NGCS and ESInet facilities to legacy 
PSAPs, permitting 911 Authorities to upgrade PSAPs to NG911 on a 
graduated basis as funding and resources become available.\155\ As with 
all of the CSP categories we adopt today, if an LPG is operated 
directly by the PSAP or 911 Authority instead of a private vendor, it 
is excluded from our covered 911 services definition and no 
certification is required.

Commission to directly regulate the ESInets' underlying transport

While we decline to classify such underlying transport or MPLS 
providers as CSPs independently, we agree that ESInet providers should 
not be required to certify to the network architecture of IP paths 
beyond the information they can reasonably obtain in service level 
agreements.\158\ Accordingly, and as discussed further below, we adopt 
additional safeguards and certification processes to ensure that all 
CSPs, including ESInet operators, can certify to the Commission that 
they satisfy reasonable reliability based on measures that they 
themselves can implement.

Location Information Servers and Transitional Gateways

    In the NG911 Reliability FNPRM, the Commission proposed to include 
Location Information Servers (LISs) and Legacy Network Gateways (LNGs) 
in the definition of covered 911 services because these services are 
critical to the call path of 911 traffic.\159\ A LIS is an NG911 
functional element that allows OSPs to send caller location information 
to PSAPs for IP networks, replacing the legacy ALI/ANI database.\160\ 
An LNG converts TDM 911 traffic from OSPs to IP format before it 
reaches an NG911 ESInet, and as such it is critical to ensure 911 
reliability during the NG911 transition.\161\ Unlike LISs, LNGs are 
transitional facilities that will be phased out when the NG911 
transition is complete.

services to two or more OSPs.\162\ This modification addresses concerns 
raised by wireless industry commenters that operate LIS and LNG 
facilities for their own traffic only.\163\ We clarify that the 911 
reliability framework does not apply to OSPs that self-provision a LIS 
or LNG, to OSPs that contract with providers of aggregated LIS or LNG 
services, or to LIS/LNG providers that only serve a single OSP.\164\

---------------------------------------------------------------------------

    To provide additional clarity as to the 911 services addressed in 
our 911 reliability framework, we also include operators of emergency 
services gateways (ESGWs), which provide critical connectivity between 
IP paths and legacy trunks connecting to a selective router, and 
operators of legacy selective router gateways (LSRGs), which provide an 
interface between legacy selective routers and ESInets during the 
transition until IP facilities are installed to replace all TDM 
facilities in the 911 call path between the OSP and the ESInet.\165\ 
Similarly to the LNG and LIS, we limit coverage of transitional 
gateways on the OSP side of the call path to those that serve two or 
more OSPs. Therefore, OSPs that self-provision their own transitional 
gateways without offering service to other OSPs, while subject to the 
OSP 911 transmission rules, are not subject to the 911 reliability 
framework.

---------------------------------------------------------------------------

    We disagree with commenters who argue against including shared LIS 
and LNG facilities as covered 911 services, as they are unambiguous 
chokepoints in NG911 architecture, not subject to state and local 
governmental or Commission direct visibility and oversight under the 
2013 reliability rules, and can benefit from reasonable reliability 
measures. At the same time, we agree with commenters that it is not 
necessary to apply the full array of reliability obligations to LIS and 
LNG facilities that apply to other critical NG911 elements. Therefore, 
we are not imposing automatic rerouting or load balancing obligations 
on LIS, LNG, or similar transitional covered 911 facilities--which are 
IP path reliability standards--but only the operational integrity 
benchmarks which apply to server facilities and similar equipment. We 
also acknowledge that the LNG is a mixed TDM-IP transitional network 
element that may not always be able to provide automatic switchover to 
redundant facilities depending on behaviors of the ``sending 
carrier's'' facilities.\166\ We reiterate that CSPs may certify to the 
Commission that they are using alternative reliability measures based 
on technology or customer limitations. In addition, as will be the case 
with similar transitional mixed TDM-IP facilities like the LPG, we will 
not dictate to CSPs whether their LNGs, LSRGs, or ESGWs should satisfy 
IP reliability practices or legacy reliability practices; so long as 
they satisfy one or the other, we will deem the practices presumptively 
reasonable. We defer to CSPs to implement the most reasonable 
combination of practices under the circumstances, including practices 
that pick and choose from both categories as alternative measures.

---------------------------------------------------------------------------

    Finally, we agree with Intrado that ``the aim should be to 
eliminate these LNGs as quickly as possible by accelerating end-to-end 
NG911.'' \167\ The Commission is actively engaged in multiple 
proceedings to expedite the NG911 and IP transitions.\168\ We take this 
opportunity to encourage all CSPs, OSPs, and 911 Authorities to 
continue to work expeditiously and cooperatively to retire their legacy 
TDM-based facilities to upgrade and replace them with IP and NG911 
facilities as fast as possible. The NG911 and IP transitions are 
interdependent and necessitate stakeholders in the NG911 ecosystem to 
coordinate, including around ensuring the reliability of 911 for the

greater visibility into how the NG911 transition is working for state 
and local governments and for the Commission and will allow us to 
exercise better oversight into these transition processes, and to help 
resolve problems where they arise.

Major IP Transport Facilities and IP 911 Traffic Aggregation Facilities

    We categorize providers of both major IP transport facilities and 
911 IP aggregation facilities as CSPs, consistent with the Commission's 
proposals in the NG911 Reliability FNPRM.\169\ However, in response to 
the record, we have narrowed the scope of our definitions of major IP 
transport facilities and 911 IP traffic aggregation facilities to focus 
on large-scale transport and aggregation facilities that would have the 
most significant impact on 911 service in the event of an outage. For 
major IP transport facilities, we raise the capacity threshold of 
services that would be subject to the 911 reliability framework. 
Moreover, for both major IP transport and 911 IP aggregation, we 
include such providers within our definitions only if they provide 
services to two or more OSPs, excluding any 911 traffic originated on 
the provider's own network.

---------------------------------------------------------------------------

    In legacy 911, most OSPs deliver 911 calls directly to their local 
ILEC, which uses selective routers to receive and route the calls to 
the appropriate PSAP. When the Commission identified selective routers 
as critical 911 facilities in the 2013 911 Reliability Order, it 
recognized that selective routers perform not only the routing function 
but also aggregate 911 calls from multiple OSPs.\170\ In the NG911 
Reliability FNPRM, the Commission recognized that, in NG911 
architecture, the routing and aggregation functions previously 
performed by ILEC selective routers are performed by an entirely new 
set of routing and aggregation facilities. Moreover, many of these 
routing and aggregation facilities are provided by third parties who 
operate downstream from OSPs but upstream from the POIs where 911 
traffic is handed off to ESInets for routing to the appropriate 
PSAP.\171\ In the FNPRM, the Commission noted that these facilities 
were not subject to the Commission's 911 transmission rules or the 
then-current 911 reliability rules because providers of third-party 
transport and aggregation services did not meet the definition of 
either CSPs or OSPs.\172\ The Commission tentatively concluded that 
these providers had become sufficiently crucial to the provision of 
NG911 service that they should be

[[Page 42807]]

subject to the same reliability requirements as other providers of 
covered 911 services.\173\ The Commission also proposed to focus 
reliability requirements on major transport and aggregation providers 
and not to extend them to smaller providers whose facilities do not 
pose a risk of widespread 911 outages.\174\

recent significant 911 outages have resulted from failure of these 
facilities.\176\ To date, neither the Commission nor 911 Authorities 
have had sufficient visibility into or oversight of these critical 
NG911 market participants to ensure reliable 911 services.\177\ 
Designating the operators of these facilities as CSPs will ensure that 
the reliability practices of these critical providers in the 911 call 
path are visible to 911 Authorities and the Commission in the event 
that problems or call failures arise.\178\

    Our action also provides greater certainty for OSPs contracting 
with third-party CSPs to provide 911 transport or aggregation. OSPs 
express concern that they could face increased risk of liability for 
911 outages caused by failures of third-party NG911 transport providers 
and aggregators if such entities are not subject to FCC regulation and 
oversight.\179\ Today's 911 reliability framework extending FCC 
oversight to transport providers will allow OSPs to better vet their 
NG911 third-party CSPs based on the FCC's NG911 reliability benchmarks. 
Similarly, strengthening the reliability of third-party aggregation 
services benefits OSPs by providing additional assurances that entities 
responsible for aggregating their customers' 911 calls are taking 
measures to support reliability.\180\

    We disagree with commenters who contend that the 911 transmission 
rules applicable to OSPs are sufficient to ensure reliability of third-
party 911 transport and aggregation between OSPs and ESInets.\181\ 
While the 911 transmission rules, in conjunction with the NG911 
transition framework, hold OSPs responsible for delivering 911 calls 
originated on their networks to ESInets and PSAPs, they do not impose 
any specific reliability obligations on the third parties that many 
OSPs rely on to accomplish such delivery. Moreover, as the Commission 
recognized in the NG911 Reliability FNPRM, the reliability practices of 
these third parties may be invisible to OSPs until after an outage has 
occurred.\182\ By applying the 911 reliability framework to third-party 
providers, we enable 911 Authorities and the Commission to work 
collaboratively with industry and state and local governments to 
prevent these kinds of 911 outages before they happen.\183\ The 
Commission's goal, through the application of this 911 reliability 
framework to major IP transport and IP 911 traffic aggregation 
facilities, is to reduce the risk of multistate or multi-OSP 911 
outages such that there are fewer instances in which callers cannot 
reach their local PSAP in case of emergency.

---------------------------------------------------------------------------

    We also disagree with commenters who contend that extending our 911 
reliability framework to third-party providers will result in OSPs 
necessarily bearing unwarranted additional costs for NG911 
reliability.\184\ Under the NG911 transition framework, OSPs are 
presumptively responsible for the costs of 911 transport to NG911 
delivery points, whether they provide such transport directly or 
through a third-party provider. However, requiring third-party 
providers to take reliability measures gives OSPs more options, not 
fewer, for controlling such costs while reducing their outage 
risk.\185\ OSPs retain flexibility to use dedicated third-party CSP 
transport or aggregation services or to directly connect to ESInets. 
OSPs that choose to use third-party CSPs will have greater assurance 
that the CSPs are providing reliable dedicated service. OSPs also have 
cost-effective options to purchase geo-diverse cloud-based paths or VPN 
circuits over the public internet--neither of which is itself a covered 
911 service, but both of which, with suitable precautions, can help 
OSPs or CSPs to achieve 911 path diversity and ensure reliable 911 
traffic delivery. OSPs may also reduce costs by reaching agreements to 
use the same IP paths between ESInets and PSAPs to send originating 
customer 911 traffic upstream to reach the NGCS facilities.\186\

    Major IP transport facilities. In the NG911 Reliability FNPRM, the 
Commission proposed to apply reliability requirements to major 
transport facilities providers, defined as providers offering OC3 or 
higher capacity (155 Mbps), and to exclude smaller transport providers 
with capacity below this threshold. Some commenters argue that the 
proposed threshold for major IP transport is too low and could be 
costly when applied to rural areas, or even impossible to achieve in 
some cases.\187\ We agree with these commenters that compliance with 
the reliability requirements imposes some costs, and that IP transport 
providers serving small and rural areas may face a greater cost burden. 
To address these concerns, we are raising the threshold for IP major 
transport to focus on the largest transport facilities that pose the 
greatest risk of causing multistate or multi-OSP 911 outages.\188\

(asking if the OC capacity threshold should be updated with a Gbps 
equivalent).
---------------------------------------------------------------------------

    We define major IP transport facilities as dedicated SIP voice and 
text transport facilities meeting or exceeding Optical Carrier 48 
(OC48)/2.5 Gbps in capacity that collect and/or transmit IP 911 traffic 
mixed with non-911 traffic from two or more OSPs, and transport it over 
interstate dedicated SIP routes, for ultimate delivery to an NG911 
Delivery Point or equivalent ESInet point of interconnection. The 
threshold for major IP transport facilities includes any 2.5 Gbps 
equivalent or higher capacity transport facilities, whether

[[Page 42808]]

using OC, ethernet, or another technology. We clarify that this CSP 
definition of major IP transport capacity does not alter any existing 
Network Outage Reporting System obligations under part 4 of our 
rules.\189\
---------------------------------------------------------------------------

    \189\ See 47 CFR 4.7(d) (defining OC3 user minutes for 
determining NORS outage reporting threshold criteria). Under the 
NORS reporting requirements, cable communications providers, IXC or 
LEC tandem facilities providers, satellite operators, SS7 providers, 
wireless service providers, and wireline communications providers 
must submit electronically a notification to the Commission when the 
outage threshold criteria pertaining to each service have been met. 
See 47 CFR 4.9(a)-(g). While an entity defined as a CSP may be 
required to report in NORS, it would be by virtue of its status as 
one of the entities regulated under Sec.  4.9(a)-(g) and not because 
of its status as a CSP.
---------------------------------------------------------------------------

    Consistent with the NG911 Reliability FNPRM proposals and goals, we 
differentiate between major IP transport providers, which we designate 
as CSPs, and general internet transit providers, which we do not 
designate as CSPs.\190\ Major IP transport providers are those network 
operators that meet the OC48/2.5 Gbps threshold and offer dedicated SIP 
service that includes voice and/or text to two or more OSPs for 911 
traffic. General internet transit includes public internet, VPN, or 
cloud-based service products and their underlying transport networks 
that provide IP connectivity but do not offer dedicated voice or text 
service.\191\ For the reasons NENA explains, we anticipate that OSPs, 
CSP major IP transport providers, and other CSPs may use general 
internet paths as diverse pathways for transport of 911 traffic to 
ensure 911 reliability.\192\ We seek to encourage and not to foreclose 
use of these available paths to support diversity and redundancy in the 
NG911 ecosystem.\193\ Therefore, while we apply our 911 reliability 
framework to CSPs even if they choose to use general internet transit 
paths for redundancy or downstream transmission, we do not classify the 
internet transit providers or their underlying transport networks as 
CSPs, and we exclude them from the CSP regulatory framework. Such 
regulation is unnecessary and would be highly burdensome; in addition, 
no commenter has requested regulation of internet paths.

    We provide relief to some OSPs offering IP transport facilities 
that otherwise meet the OC48/2.5 Gbps threshold by further limiting the 
definition of major IP transport facilities to those transporting the 
911 traffic of two or more OSPs. To account for instances in which a 
major IP transport facility provides transport to another OSP on an 
incidental basis, we exclude 911 traffic originated on the provider's 
network in the determination of whether a particular facility is 
transporting the 911 traffic of two or more OSPs. Accordingly, an OSP 
that transports its own voice and text 911 traffic, plus the 911 
traffic of one other OSP, is not a provider of major IP transport 
facilities, regardless of whether it meets the increased threshold 
definition. We agree with NCTA that this change helps us achieve our 
goals of balanced regulation by requiring reliability best practices 
only for network facilities carrying substantial risk of multi-OSP 
outages.\194\ This change also avoids imposing undue burdens on OSPs 
that provide limited and incidental third-party transport 
services.\195\ To harmonize our 911 reliability framework and ensure 
consistency, we apply these same changes to the definition of IP 911 
traffic aggregation facilities, which must carry 911 traffic for two or 
more OSPs, not counting any 911 traffic originated on the facility 
provider's own network.

    We further exclude any dedicated SIP transport that is exclusively 
used to carry data traffic with no dedicated OSP voice or text to avoid 
capturing non-911 transport, as requested by NCTA and Intrado.\196\ We 
believe these exclusions narrow the proposal sufficiently to avoid 
unnecessary burdens.\197\ Accordingly, our definition of major IP 
transport facilities includes providers that comingle 911 traffic 
transport from two or more OSPs with general OSP voice traffic. We 
believe this revised definition reasonably ensures reliability of major 
NG911 traffic conduits to ESInets without overburdening industry. Our 
priority is the reliability of the largest interstate transport routes 
and facilities carrying 911 traffic from two or more OSPs, the failure 
of which poses the greatest risk to the transmission of 911 traffic for 
the public. Today's modifications accomplish this goal, while also 
creating regulatory certainty for business and avoiding undue burdens 
and costs for entities that provide IP transport but carry little or no 
dedicated 911 traffic.

    Our implementation of these exclusions, and raising of the IP 
transport capacity threshold, mitigate concerns raised by commenters 
that some IP transport providers may be unable to ascertain whether 
they carry 911 traffic.\198\ Because only large providers that serve 
two or more OSPs fall under the major IP transport definition, we 
believe it is reasonable to expect them to inquire as to whether or 
infer that they carry 911 traffic. Under the Commission's robocall 
mitigation and know-your-customer rules, voice service providers have 
an affirmative responsibility to know their upstream providers and the 
nature of the traffic they are receiving from those providers to ensure 
their networks or services are not being used to transmit illegal 
calls.\199\ The Commission's call blocking rules also require or permit 
providers to block calls under certain conditions, but place robust 
restrictions on blocking of 911 and other emergency calls.\200\ At 
most, the downstream providers of high-capacity, interstate long-haul 
dedicated

[[Page 42809]]

SIP transport must ask OSPs or upstream providers whether their traffic 
includes 911 traffic, or if the OSP has segregated out its 911 traffic 
prior to handoff. To the extent major IP transport providers are not 
already inquiring about this from their upstream customers, we believe 
it is a reasonable measure to reduce the risk of large-scale 911 
outages.

    IP 911 traffic aggregation facilities. The Commission proposed in 
the NG911 Reliability FNPRM to require third-party operators of IP-
based 911 aggregation facilities to implement reliability practices 
because a large percentage of 911 traffic passes through such 
facilities.\201\ The Commission stated in the FNPRM that IP 911 
aggregation facilities have become critical to the transmission of 911 
traffic,\202\ and that IP 911 aggregation services have already emerged 
as a significant market during the transition to NG911.\203\ The record 
confirms that IP 911 traffic aggregation is a critical NG911 function 
that should be covered by our 911 reliability framework.\204\ We 
therefore designate IP-based 911 aggregators as CSPs to ensure 
visibility and oversight into providers for which OSPs may not have 
substantial leverage or practical control, and for which the FCC and 
state and local governments lack visibility or oversight.

    We define IP 911 traffic aggregation facilities as IP-based 
facilities that collect and segregate 911 traffic from non-911 traffic 
for two or more OSPs, or that aggregate and transport 911-only traffic 
from two or more OSPs for ultimate delivery to NG911 delivery 
points.\205\ Unlike major IP transport facilities, for which we define 
a capacity threshold, we do not put such a threshold on IP-based 911 
aggregation facilities because, by definition, these facilities handle 
only 911 traffic. Any entity that collects and segregates IP 911 
traffic from non-IP 911 traffic on behalf of two or more OSPs must meet 
the reliability requirements because the aggregation of 911 traffic 
creates a heightened risk to 911 callers if there is an outage. We 
reiterate that an OSP hiring an IP 911 traffic aggregator is not a CSP, 
nor is an OSP providing 911 IP aggregation for its own traffic or that 
of its wholly-owned subsidiaries or operating companies.\206\ We also

    IP 911 traffic aggregators that lack visibility into the paths of 
their 911 traffic via underlying networks may certify to the 
reliability measures they are taking in the same way we have specified 
for ESInet operators.\208\ Specifically, IP 911 traffic aggregators may 
identify the underlying network providers they have retained to ensure 
path diversity, the visibility into network architecture those 
providers offer via service level agreements, and any additional multi-
homing, cloud-based, or VPN backup measures the IP 911 aggregator is 
using to ensure path diversity. As in the case of underlying network 
providers that support ESInet operations, underlying network providers 
that contract to carry the traffic of a 911 IP aggregator are not CSPs 
if they do not otherwise meet the CSP definition.\209\ However, we 
recognize that market arrangements are not identical across the NG911 
ecosystem, and we want to ensure our 911 reliability framework is 
flexible enough to adapt to changing conditions. Accordingly, in 
situations where OSPs segregate 911 traffic on their own network and 
send it to a third-party carrier for dedicated SIP transport, those 
third-party carriers would also be CSPs under the IP 911 traffic 
aggregator definition we adopt, provided they aggregate 911 traffic 
from two or more OSPs.\210\ We reiterate that, in such cases, the same 
minor effort we expect of major IP transport providers to inquire of 
their customers or upstream providers would apply to IP 911 traffic 
aggregators as well.\211\

Interstate Interconnecting ESInet Facilities

    We adopt the proposal from the NG911 Reliability FNPRM to designate 
operators of interstate interconnecting facilities between ESInets as 
covered 911 service providers.\212\ Interstate interconnecting ESInet 
facilities are interstate facilities that transport IP 911 traffic from 
an ESInet for ultimate delivery to another ESInet, including facilities 
designated for intermittent, contingent, or backup exchange of IP 911 
traffic between ESInets. We believe it is reasonable to treat 
interstate ESInet interconnection providers as CSPs in instances where 
911 Authorities elect to connect ESInets with one another across state 
lines. Connections between ESInets can provide important resiliency 
during natural disasters and other major emergencies,\213\ but only if 
those connections between ESInets are sufficiently reliable. We 
therefore designate the operation of interstate interconnecting ESInet 
facilities as a covered 911 service and subject the associated 
facilities supporting interconnection to IP path diversity 
requirements.\214\

Reliability Requirements

Reasonable Measures

    We adopt our proposal to make the new classes of IP-based CSPs 
identified above subject to 911 reliability requirements.\215\ This 
will require them to take reasonable measures to provide reliable 911 
service with respect to physical diversity, network monitoring, and 
operational integrity.\216\ The structure of our framework provides 
CSPs with regulatory clarity and enables them to implement consensus-
driven IP reliability best practices that marshal the flexible 
capabilities of IP architecture, such as automatic rerouting and 
geodiversity.\217\ In addition, our framework preserves flexibility 
such that CSPs may satisfy

[[Page 42810]]

the reliability requirement by performing each element of the 
reliability benchmarks or by adopting alternative measures in lieu of 
any specifically-delineated benchmark that are reasonably sufficient to 
mitigate the risk of failure. A CSP also may certify that one or more 
benchmarks are inapplicable to its network.
---------------------------------------------------------------------------

    \215\ Appendix A (Sec.  9.19(b)).
    \216\ The physical diversity and operational integrity 
benchmarks will only apply to specified classes of NG911 and IP 
CSPs. We expect our amendments to regulatory text will provide 
clarity for CSPs as to which benchmarks they must certify. 
Nevertheless, we will retain the option for CSPs to certify that a 
benchmark is not applicable to their services or facilities.
    \217\ See NG911 Transition Order, 39 FCC Rcd at 8221-22, para. 
185 & n.546 (``NG911 materially reduces the number of 911 outages by 
improving network availability and reliability as IP allows for 
greater redundancy. It provides greater geodiversity for PSAPs--no 
longer will there be a single point of failure at a selective 
router.'') (internal citation omitted).
---------------------------------------------------------------------------

    Expanding the reasonableness requirement to additional IP-based 
CSPs critical to NG911 fulfills the Commission's longstanding 
commitment to keep the 911 reliability framework current as the 
technology landscape evolves. The Commission has advised for years 
that, when appropriate, it would expand the rules ``to cover new best 
practices or additional entities that provide NG911 capabilities[.]'' 
\218\ We conclude that extending the reasonableness requirement to 
additional IP-based CSPs is a logical and timely step that aligns the 
updated 911 reliability framework with the NG911 networks increasingly 
in use and strengthens the overall integrity of the nation's 911 
system. We also conclude that it is reasonable for NG911 CSPs to 
protect network reliability by adhering to prevailing industry 
standards.\219\ Our benchmark framework provides a consistent basis for 
the Bureau to exercise its delegated authority to investigate and 
validate the reliability of 911 networks based on CSPs' certifications, 
and it enables the Bureau to monitor trends in these networks in order 
to identify and proactively mitigate potential risks to 911 
service.\220\

---------------------------------------------------------------------------

    Our approach also facilitates state, local, and tribal planning and 
control of 911 networks and implementation of NG911 in their 
jurisdictions. For example, in NG911 systems, a state 911 Authority may 
decide that paying for diverse IP transmission paths to remote or rural 
PSAPs is cost prohibitive, and that a preferred approach would be to 
implement NGCS policy routing functions that automatically reroute 
calls to available PSAPs when one PSAP goes offline.\221\ Even at this 
early stage of NG911 deployment, this NGCS policy routing technology 
has already worked to connect people to 911 during a natural disaster 
when the local PSAP's communication connections were disabled.\222\ We 
expect 911 Authorities to take advantage of these new capabilities as 
cost-effective reliability solutions, and we expect to find these 
capabilities to be reasonable alternatives in those circumstances--as 
the Commission has judged similar technologically reasonable 
alternatives in the past.\223\ Accordingly, our 911 reliability 
framework affords 911 Authorities flexibility to fashion such solutions 
as part of their contracts with CSPs and based on specific local 
conditions.\224\

with those commenters that suggest replacing our 911 reliability 
framework with a requirement for CSPs to stay compliant with 
reliability standards developed by external standards bodies, such as 
NENA and ATIS.\226\ Commenters advocating this view do not agree on 
which external standards the Commission should endorse, nor do they 
explain why those standards are preferable to the Commission's 
reliability framework, which draws heavily from cumulative 
recommendations made by CSRIC. We believe CSRIC is an ideal source of 
guidance because it is dedicated to NG911 reliability and other public 
safety communications issues, and its membership includes expert 
representatives from major service providers, industry trade groups, 
manufacturers, government agencies, public safety interest groups, and 
industry- and public safety-led standards bodies.\227\ CSRIC's work is 
collaborative and consensus-driven, and so the best practices it 
recommends generally involve aspects of service that most providers are 
already adopting consistently.\228\ Using the Commission's rulemaking 
process to periodically update reliability standards ensures 
transparency and affords CSPs the opportunity to help inform our 
actions. The Commission will continue to monitor the root causes of 911 
outages, the reliability practices that CSPs report that they have 
implemented, and CSRIC's future recommendations regarding 911 
reliability best practices, and will consider updating the 911 
reliability framework as necessary.

Benchmarks

Physical Diversity

    We update the physical diversity benchmark and several related 
definitions to reflect the prevailing mechanisms by which IP networks 
can and should provide reliable traffic delivery through physically 
diverse functional elements.\229\ Specifically, we require IP-based 
CSPs to certify, for all the IP covered 911 paths in their networks, 
whether they have implemented automatic rerouting and failover 
capabilities, load balancing, and geographically distributed routing 
facilities, transport nodes, and node

[[Page 42811]]

links sufficient to reasonably mitigate the risks of single points of 
failure. This is a modification of the benchmark proposed in the NG911 
Reliability FNPRM, which would have required CSPs to eliminate all 
single points of failure rather than mitigate them. CSPs meeting this 
new benchmark are required to mitigate these risks in both the physical 
and logical layers of 911 transport. CSPs may meet the benchmark 
through alternative measures if appropriate, or they may certify that 
the diversity benchmark is inapplicable to their networks. We also 
clarify that CSPs may secure dedicated diverse backup paths outside of 
their engineered networks, including MPLS transport, cloud-based path 
redundancy, or VPN services over the public internet, and implement 
logical diversity such as through multi-homing, to mitigate the risk of 
single points of failure.
---------------------------------------------------------------------------

    \229\ Appendix A (Sec.  9.19(c)(1)).
---------------------------------------------------------------------------

    Updates to the physical diversity benchmark. We find that updating 
the physical diversity benchmark is necessary to ensure that our 
reliability framework keeps pace with the technological realities of 
IP-based NG911 networks. These networks, when engineered properly, can 
achieve highly resilient call delivery, and requiring them to 
incorporate prevailing reliability practices ensures CSPs will 
implement these resiliency features consistently. Updating the 
benchmark also streamlines the reliability certification process for 
IP-based CSPs, because they will no longer need to provide detailed 
descriptions of their IP-based mitigation practices as ``alternative 
measures'' to an inapplicable legacy standard.\230\
---------------------------------------------------------------------------

    \230\ We are not persuaded by Lumen's concern that the benchmark 
might conflict with the reliability implementations of CSPs that 
already have ``fortif[ied] their networks.'' See Lumen Comments at 
7. These CSPs likely incorporated the prevailing measures we adopt 
today, or they may certify their configurations as alternative 
measures if appropriate.
---------------------------------------------------------------------------

    Mitigating single points of failure. Both legacy, circuit-switched 
911 networks and IP-based NG911 networks address the risks posed by 
single points of failure through physical diversity, but the strategies 
they use to do so are fundamentally different.\231\ Legacy 911 networks 
determine the circuits and switches that a call will traverse from its 
origin to its destination when the call is set up. This means that a 
problem in any network component along the planned route can cause the 
transmission to fail. Legacy networks minimize that risk by providing 
at least two independent sets of physically-separated circuits and 
switches, which eliminates the possibility that a failure of any single 
network element will disrupt the transmission.\232\ The legacy physical 
diversity benchmark reflects this strategy, as it requires CSPs to 
certify whether they have eliminated all single points of failure along 
their critical 911 circuits.\233\
---------------------------------------------------------------------------

    \231\ In general, ``physical diversity'' means that data between 
two points in a network can be transmitted over diverse routes that 
do not share any common physical segments, such as fiber-optic 
cables, conduits, or structures, so that a single failure at any 
point on one of those data paths, such as a power outage, equipment 
failure, or cable cut, would not cause both paths to fail and 
disrupt the transmission of data between those points. 47 CFR 
9.19(a)(8). See also NENA, NENA Knowledge Base, https://kb.nena.org/wiki/SIP (last visited May 19, 2026) (``Single Point of Failure is a 
failure of a hardware or software component or sub-system which 
causes a system to fail.'').
    \232\ See, e.g., 911 Reliability Order, 28 FCC Rcd at 17504, 
para. 83 (``Physical diversity, sometimes called route diversity, 
means that two circuits follow different routes separated by some 
physical distance so that a single failure such as a power outage, 
equipment failure, or cable cut will not result in both circuits 
failing.''); 47 CFR 9.19(a)(8) (defining physical diversity); NENA 
Comments at 23 (``When considering physical diversity, conventional 
wisdom within telecom has always been `two of everything at each of 
two sites.' '').
    \233\ 47 CFR 9.19(c)(1)(i).
---------------------------------------------------------------------------

    In contrast, NG911 and IP networks create physical diversity 
primarily by being capable of automatically and dynamically rerouting 
911 traffic throughout a web of alternate paths.\234\ The IP routers or 
nodes in the network decide where to forward packetized call data based 
on internal routing tables, connected by IP paths and node links.\235\ 
If a router or node detects a failure in the primary path, it 
automatically and instantly reroutes the call along a secondary path. 
This capability means that, ``[i]f there is any path between two points 
in an IP network, then the network will automatically find and use that 
path.'' \236\ Because NG911 networks can deliver traffic along numerous 
possible routes, physical separation of individual IP paths may not be 
essential in all locations to achieve reasonable network 
reliability.\237\ Instead, NG911 networks create resiliency by 
maintaining redundant routers or nodes and node links that 
automatically failover to redundant elements and paths. These networks 
typically space redundant elements widely in different geographic 
locations and different physical facilities to protect them from 
failing due to the same external event.\238\ These networks practice 
load balancing by dynamically distributing network traffic across 
multiple available databases or call processing facilities so that the 
network maintains continuity of service to prevent redundant elements 
from becoming overwhelmed even when traffic surges.\239\ The physical 
diversity benchmark we adopt today is broadly worded to reflect these 
prevailing approaches while remaining technology-neutral so as to 
provide legacy and NG911 CSPs a high degree of flexibility when 
choosing their implementation strategies.

---------------------------------------------------------------------------

    The specific capabilities we incorporate into the physical 
diversity benchmark--automatic rerouting and failover across 
geographically-distributed routing facilities, transport nodes, and 
node links, supported by load balancing--are well-recognized strategies 
that are synonymous with sound IP architecture. In its 2013 Derecho 
Report, the Bureau found that NG911 networks would likely have 
mitigated the 911 outages caused by the 2012 derecho due to the 
resiliency and redundancy these networks provide using IP routers with 
automatic fail-over; automatic rerouting; and diverse IP paths.\240\ 
When CSRIC updated its best practice recommendations for NG911 in 2019, 
it assumed that the design of transitional and end-state ESInets would 
ensure ``all network elements and transport facilities are deployed 
with redundancy.'' \241\ CSRIC explained that ``[t]ypically, network 
redundancy is achieved through the addition of alternate network paths, 
which are implemented through redundant standby network elements, 
routers and switches. When the primary path is unavailable, the 
alternate path

[[Page 42812]]

can be instantly deployed to ensure continuity of network services.''

    Our benchmark also reflects CSRIC's best practice recommendations 
for NG911 service providers. CSRIC recommends that service providers 
ensure the geographic separation of network redundancy facilities; 
dedicated, geo-diverse, and redundant IP connection points; functional 
redundancy and geographic diversity for critical network elements; 
physical and geographic redundancy for critical facilities links; 
diverse routing from OSPs to the ESInet; and redundant connectivity 
from the ESInet to PSAPs.\243\ It further recommends that service 
providers manage ``critical network elements and architecture that are 
essential for network connectivity and subscriber services considering 
. . . functional redundancy and geographical diversity''; ``ensure that 
networks built with redundancy are also built with geographic 
separation where feasible (e.g., avoid placing mated pairs in the same 
location and redundant logical facilities in the same physical path)''; 
use load balancing to ``ensure that the utilization on either node is 
less than half of each node's capacity so that if one node fails the 
other node will absorb the load''; and ``plac[e] and maintain[ ] 9-1-1 
. . . IP based networks over diverse interoffice transport facilities 
(e.g., geographically diverse facility routes), automatically invoked 
standby routing, diverse digital cross-connect system services, self-
healing fiber ring topologies, or any combination thereof.'' \244\

---------------------------------------------------------------------------

    Commenters identify other logical and physical diversity mitigation 
strategies, including the use of diverse MPLS transport, cloud-based 
services, or the public internet as automatically re-routed backup 
paths.\245\ Although the record demonstrates that these strategies can 
make NG911 more resilient, we decline to specify that any of them is a 
benchmark practice at this time.\246\ CSRIC has not identified these 
practices as necessary to all NG911 implementations, and we are 
concerned that requiring them could be overly prescriptive or cost 
prohibitive in some scenarios. NG911 networks vary substantially in 
size, geography, legacy configurations, and available commercial 
infrastructure, and the benefits of these measures may depend on 
technical and economic factors that differ across jurisdictions. 
Instead, we identify these approaches as permissible mitigation 
strategies and strongly encourage CSPs to adopt them where appropriate 
to enhance resiliency. This approach preserves flexibility for 
providers to tailor their reliability solutions to their own 
operational environments while ensuring that foundational NG911 
reliability standards remain clear, achievable, and technologically 
neutral.\247\
---------------------------------------------------------------------------

    \245\ See, e.g., NENA Comments at 9-11, 20; Brian Rosen Reply at 
5. Intrado suggests replacing the physical diversity benchmark 
entirely with a requirement for CSPs to secure backup paths via 
other providers' networks. See Intrado Comments at 21 (``[T]he 
standard could be to require a CCSP to procure a minimum number of 
diverse connections from different network providers with a minimum 
number of points of interconnection in geographically diverse 
locations.'').
    \246\ See, e.g., USTelecom Comments at 8 (``In many cases, 
modern networks inherently offer greater reliability, not because of 
any single element such as physical route diversity, but because of 
a combination of design strategies tailored to specific network 
environments and operational needs.'').
    \247\ Verizon Reply at 4 (``[C]ommenters broadly recognize the 
need for flexibility in applying any new `conformance' and 
`alternate measures' certification standards.'').
---------------------------------------------------------------------------

    We leave unchanged the physical diversity requirements for legacy 
CSPs, but take this opportunity to revise the requirements for brevity 
and clarity.\248\ Legacy CSPs may continue to satisfy the physical 
diversity benchmark by ensuring that all covered 911 circuits in their 
network are tagged and physically diverse such that no network or 
facility element constitutes a single point of failure and by 
conducting annual diversity audits. In addition, both legacy and IP 
CSPs retain the option to implement alternative measures to the 
benchmarks that mitigate the risks of a lack of physical diversity or 
to demonstrate that the physical diversity requirements do not apply to 
one or more covered portions of their networks.\249\
---------------------------------------------------------------------------

    \248\ See NG911 Reliability FNPRM, 40 FCC Rcd at 2693, para 62.
    \249\ We reject Lumen's claim that the benchmark imposes 
inescapable requirements on CSPs. See Lumen Comments at 6. While it 
reflects best practices that are feasible in typical NG911 
deployments and should be followed in most cases, CSPs may certify 
alternative measures if necessary.
---------------------------------------------------------------------------

    Definitions. To facilitate compliance with the physical diversity 
benchmark, we update the definition of ``physically diverse'' to 
incorporate the IP benchmark capabilities that we describe above, as 
well as to reference ``paths'' in addition to ``circuits,'' so that the 
definition accurately reflects common terminology for IP transport 
elements.\250\ We also adopt new definitions for the terms 
``geographically distributed'' and ``load balanced'' based on their 
meanings as described in the NG911 Reliability FNPRM and as previously 
recognized by the Commission.\251\ We find that adopting functional 
definitions of these terms will explain important technical concepts 
reflected in the physical diversity benchmark, provide guidance to CSPs 
seeking to implement the benchmark, and assist 911 Authorities and 
other stakeholders responsible for overseeing the provision of reliable 
911 service. Accordingly, we adopt the following definitions:

Furthermore, if two or more PSAPs share the same 911 service 
provider and rely on each other as a backup PSAP for rerouting of 
911 calls, the 911 service provider should consider assigning each 
PSAP to a different primary routing database.'')).
---------------------------------------------------------------------------

     Physically diverse. Circuits or paths are physically 
diverse if they provide more than one physical route between end points 
with no common points where a single failure at that point would cause 
both circuits or paths to fail. Circuits or paths that share a common 
segment such as a fiber-optic cable or circuit board are not physically 
diverse even if they are logically diverse for purposes of transmitting 
data. IP routers, transport nodes, and node links create physical 
diversity if these elements are redundant, geographically distributed, 
load balanced, and capable of automatic failover and rerouting to 
redundant elements sufficient to reasonably mitigate the risks of 
single points of failure.
     Geographically distributed. 911 network architecture is 
geographically distributed if 911 traffic can be delivered through more 
than one covered 911 circuit or path in different geographic locations 
in different physical facilities.
     Load balanced. 911 network architecture is load balanced

processing facilities to accommodate changes in traffic volume.
    The Commission asked in the NG911 Reliability FNPRM whether it 
should define geographic distribution more specifically to mean the 
housing of functional elements in different cities or states.\252\ We 
decline to further specifically define geographic distribution at this 
time. Any fixed standard for geographic distribution could prove too 
prescriptive or invalidate some existing IP network architectures. We 
also expect that national NG911 CSPs naturally will space their routing 
elements widely across different regions and that state and local 911 
Authorities will negotiate the placement of NG911 facilities within 
their jurisdictions to maximize reliability. We therefore find it 
unnecessary at this time to define geographic diversity with greater 
specificity than as proposed in the NG911 Reliability FNPRM.
---------------------------------------------------------------------------

    \252\ Compare, e.g., NENA Comments at 22 (routing elements 
should be distributed widely so that they are not affected by the 
same weather events), with Comtech Comments at 18 (``[G]eographic 
diversity is a continuum and is inherently more subjective (e.g., 
whether network elements are sufficiently far apart geographically . 
. . .'').
---------------------------------------------------------------------------

    The physical diversity benchmark applies to ``covered 911 circuits 
and paths.'' \253\ Accordingly, we update the definition of this term 
as well so that it includes the IP-based transport facilities we newly-
designate today as covered facilities. Specifically, we adopt the NG911 
Reliability FNPRM's proposal specifying that the IP paths covered by 
our 911 reliability framework include major IP transport paths, IP 911 
traffic aggregation paths, interstate interconnecting ESInet 
facilities, and IP traffic paths from NGCS facilities to PSAPs.\254\

    \256\ See 47 CFR 9.19(a)(5). The NG911 Reliability FNPRM 
proposed to include the ESInet and NGCS by reference to them as 
``functional equivalents'', but the definition we adopt today 
defines critical IP paths more explicitly by their location and 
function to provide regulatory clarity. See NG911 Reliability FNPRM,

---------------------------------------------------------------------------

    To avoid any ambiguities going forward, we remove language from the 
proposed IP covered 911 paths definition referencing ``central 
offices,'' and add language covering ``circuits,'' in order to respond 
to concerns from CCOA and NASNA.\257\ CCOA states that legacy providers 
of paths to PSAPs have argued that the 2013 circuit auditing and 
diversity benchmarks do not apply to them.\258\ NASNA adds that the 
Commission's proposed definition of critical 911 paths to PSAPs is 
inadequate to capture the full range of ESInet traffic.\259\ Updating 
this language is important both for current clarity where ILECs 
continue to route 911 traffic to PSAPs through legacy central offices 
and networks and for modernized and upgraded networks as legacy central 
offices are retired and replaced by IP-based paths.

---------------------------------------------------------------------------

    We decline to exclude intermediate paths in the chain of delivery 
from our definitions of covered IP paths, as this would allow providers 
to circumvent our reliability regime merely by handing off traffic to 
another entity.\260\ However, we reiterate that IP 911 traffic 
aggregators may make the same certifications as ESInet operators about 
which underlying transport providers or MLPS vendors they have service 
level agreements with, the extent to which those providers are sharing 
network data or delivering path diversity as promised, and any multi-
homing or other measures the IP 911 aggregators are implementing to 
ensure IP path diversity. The IP diversity benchmark we adopt today, 
which incorporates geo-diversity per the CSRIC best practices, provides 
robust reliability that should reduce the risk of 911 outages resulting 
from fiber cuts--and particularly instances where a fiber cut in a 
single location results in a 911 outage across an entire state or 
region. If the Commission receives reports that underlying transport 
providers are not reasonably cooperating to ensure 911 reliability, and 
that this lack of cooperation is resulting in 911 outages, we can 
revisit our CSP categories at that time.

4 (``[W]hen the combined traffic of multiple OSPs is not delivered 
directly but is instead delivered to a second aggregator in the call 
delivery path where it is aggregated with the second aggregator's 
combined traffic, the risk of an outage affecting the delivery of 
each OSP's traffic increases at least two-fold at the second 
aggregation point.'').
---------------------------------------------------------------------------

    The updated IP physical diversity benchmark and associated 
definitions have strong support from public safety commenters.\261\ 
CCOA, for example, believes the benchmark strengthens reliability by 
requiring CSPs to ``provide physical diversity'' that is ``necessary 
and critical to the foundation on which NG911 core services will 
operate.'' \262\ Commenters note the importance of adding a requirement 
for geographic diversity, because it protects 911 service against more 
causes of outages than simple physical diversity.\263\

[[Page 42814]]

Commenters also support retaining the physical diversity benchmark for 
legacy providers, which we do.\264\ We decline Lumen's suggestion to 
modify the benchmark for IP path diversity by identifying auditing and 
tagging as presumptively reasonable, because auditing and tagging are 
legacy TDM reliability practices that do not necessarily measure the 
inherently more-resilient geodiversity of IP networks.\265\ However, 
CSPs may certify to auditing and tagging their IP paths to ensure 
complete physical route diversity as an alternative measure. We also 
decline to adopt one commenter's suggestion to require legacy CSPs to 
produce new types of data during diversity audits of critical circuits 
and to require all OSPs to perform diversity audits as well.\266\ These 
changes would greatly expand the scope and burden of the diversity 
benchmark, and there is insufficient evidence in the record to suggest 
that such an expanded requirement would provide commensurate benefits.

---------------------------------------------------------------------------

    Support for the diversity benchmark from service providers is 
mixed, but several providers oppose the benchmark language proposed in 
the NG911 Reliability FNPRM in whole or in large part because it would 
have required IP physical diversity measures that ``eliminate all 
single points of failure.'' \267\ They argue that such a requirement 
would be cost prohibitive or infeasible, because NG911 networks reroute 
calls dynamically without preplanning or tracing call routes, and 
packetized call data may sometimes converge at single points without 
the provider being aware.\268\ We acknowledge that eliminating all 
single points of failure is not presently a design goal of typical 
NG911 deployments, and we have revised the IP physical diversity 
benchmark accordingly to require reasonably sufficient mitigation of 
single points of failure.
---------------------------------------------------------------------------

    \267\ See NG911 Reliability FNPRM, 40 FCC Rcd at 2729; see also, 
e.g., Motorola Comments at 7-8 (arguing that, if this language were 
corrected, the resulting benchmark ``would accomplish the FCC's goal 
of ensuring that `critical paths established by CSPs [are] 
geographically diverse, load-balanced, and capable of automatic 
failover to the backup element . . . and automatic reroutes to 
redundant paths in the transport layer in the event of path 
failure,' while recognizing the operational realities of NG911 
networks.''); iCERT Comments at 15 (expressing support if the

that calls may take within the network.'').
---------------------------------------------------------------------------

    In response to Intrado's concern that upstream or downstream 
providers could interfere with its performance of the benchmark, we 
clarify that a CSP's compliance depends solely on the CSP's 
configuration and operation of facilities under its control.\269\ We 
emphasize, however, that CSPs must take full responsibility for meeting 
the benchmarks, or implementing reasonable alternative measures, and 
that nonperformance with respect to facilities under the CSP's control 
cannot be justified by the practices or limitations of third parties. 
The 911 reliability framework, together with the Commission's NG911 
transition framework, synergistically afford providers and 911 
Authorities the flexibility and control they need to plan and deploy 
seamless NG911 connectivity. To use Intrado's hypothetical example, a 
NGCS CSP and 911 Authority that provide two entry points to an ESInet 
to support geographic diversity can require OSPs to deliver 911 traffic 
to both POIs in a format that is compatible with the CSP's network 
configuration.\270\
---------------------------------------------------------------------------

    \269\ See Intrado Comments at 16-17; id. at 21-22 (``[A]n NGCS 
provider can provide OSPs with an interconnection guide and 
recommendations for redundant connectivity, load balancing, and 
advance routing, but it cannot force the OSP to purchase or 
configure a particular architecture.''). See also Verizon Comments 
at 14 (suggesting the 911 Authorities' readiness could impact OSPs' 
performance).
    \270\ See Intrado Comments at 21; 47 CFR 9.32 (``A 911 Authority 
may designate one or more NG911 Delivery Points where [OSPs] must 
deliver 911 traffic to the ESInet[.]''); 47 CFR 9.29(a) (At Phase 1, 
OSPs must ``[d]eliver all 911 traffic . . . in the IP-based SIP 
format requested by the 911 Authority''). We remind providers that, 
if they cannot conform to a benchmark practice, they may implement 
reasonable alternative measures. Cf. Intrado Comments at 17-18.
---------------------------------------------------------------------------

    Other IP reliability measures. For clarity, the updated benchmark 
does identify several examples of diverse IP paths that CSPs may adopt, 
but it does not require that any specific one, or all, of them be 
implemented.\271\ Significant developments in network design and 
operational practices in recent years have allowed modern NG911 and IP 
networks to employ additional strategies to increase the reliability of 
call transmission.\272\ Providers may create additional geo-diverse 
redundancy beyond their own engineered paths by securing backup paths 
from third-party cloud- or internet-based solutions.\273\ These 
solutions typically connect into the CSP's network through secure, SIP-
capable interfaces that automatically activate if the CSP's primary 
path fails. The services then deliver 911 traffic through the cloud or 
over the public internet using a VPN for security. Third-party services 
may handle call delivery, or they may provide a routing solution and 
hand off 911 traffic to a non-failing portion of the CSP's network or 
to another CSP for delivery. CSPs also may arrange backup paths over 
the public internet without using third-party services.\274\ We note 
that using the public internet may expose 911 traffic to risks such as 
possible Denial of Service (DoS) and Telephony Denial of Service (TDoS) 
attacks, making enhanced security protections advisable. While we do 
not mandate such measures today, we encourage OSPs and CSPs relying on 
the public internet for backup purposes to implement common-sense 
security measures to protect the reliability of 911 traffic.\275\

---------------------------------------------------------------------------

    NG911 providers may also secure access to dedicated third-party 
high-capacity physical transport that is geographically diverse from 
their own facilities, such as MPLS networks that transport data between 
nodes based on short path labels, which avoids complex

[[Page 42815]]

lookups in routing tables.\276\ CSRIC notes the use of MPLS transport 
as an optional method to increase redundancy in ESInets but does not 
designate it a high-priority capability for all CSPs.\277\ We find that 
CSPs may use dedicated diverse private facilities such as MPLS, cloud-
based path redundancy, or VPN services over the public internet, or 
equally secure industry protocols as additional automatically re-routed 
backup paths.

network (VPN), or equally secure industry protocols) and where 
appropriate and supported by service level agreements.'').
---------------------------------------------------------------------------

    CSPs may also mitigate the risk of internal network failures by 
employing various forms of logical diversity.\278\ Logical diversity is 
the use of multiple, independent routing instructions or virtual paths 
through an IP network.\279\ Unlike physical and geographic diversity, 
which require network facilities to be separated by physical space, 
logical diversity can operate within shared infrastructure and relies 
on independent routing logic to bypass failures in a network's 
processes.\280\ Multi-homing is a form of logical diversity used in 
some NG911 networks.\281\ It involves connecting critical network 
elements to multiple independent upstream networks or service providers 
simultaneously. This configuration establishes multiple distinct 
routing paths at the network layer, but some underlying physical 
infrastructure may overlap. As a result, multi-homing enhances overall 
network reliability and resiliency against outages, congestion, or 
localized network disruptions. CSRIC recommends the use of logical 
diversity strategies like multi-homing in addition to physical 
diversity where feasible.\282\
---------------------------------------------------------------------------

    \278\ See, e.g., CSRIC VI WG 1 Report at 122 (``Network 
Operators . . . and Service Providers should, where feasible,

links.'').

---------------------------------------------------------------------------

Operational Integrity

    We adopt the NG911 Reliability FNPRM proposal to (1) update the 
``backup power'' benchmark so that it applies to IP-based CSPs that 
operate multi-OSP LNGs, multi-OSP LISs, or covered NGCS functional 
elements, and (2) change the benchmark name to ``operational 
integrity'' to better reflect the methods by which IP networks protect 
service continuity.\283\ We additionally specify that operators of 
covered LSRGs, ESGWs, and LPGs are subject to the benchmark, consistent 
with our determination in this Order that these elements are essential 
to transitional NG911 networks.\284\ IP CSPs meet the benchmark if 
their covered facilities have the capability to ensure continuity of 
services via an uninterruptible and continuous power supply and 
automated switchover to geographically diverse backup facilities and 
configurations sufficient to prevent service disruption. For legacy 
CSPs, the backup power requirements for central offices remain the same 
substantively, but we implement minor updates to improve readability. 
All legacy and IP CSPs also retain the option to achieve operational 
integrity through alternative measures.\285\
---------------------------------------------------------------------------

    \283\ Appendix A (Sec.  9.19(c)(2)).
    \284\ NG911 Reliability FNPRM, 40 FCC Rcd at 2696, paras. 69-70.
    \285\ 47 CFR 9.19(c)(2)(ii).
---------------------------------------------------------------------------

    Extending the operational integrity benchmark to CSP operators of 
covered LNGs, LISs, LSRGs, ESGWs, LPGs, and NGCS functional elements is 
appropriate because those facilities perform 911 call aggregation, 
routing, and delivery functions analogous to the functions performed at 
central offices in legacy 911 networks, to which the 2013 legacy backup 
power benchmark applies.\286\ These functions are essential to NG911 
connectivity, and their failure can disable the transmission of 911 
traffic across entire communities or even large areas of the 
country.\287\ However, we do not extend this benchmark to CSP providers 
of major IP transport facilities or IP 911 traffic aggregation 
facilities, for which geographically diverse failover capability may 
not be practical and supplying continuous backup power is likely to be 
inapplicable or unduly burdensome. While we find the operational 
integrity benchmark to be inapplicable to these CSP categories, we 
emphasize that they remain subject to the redundancy and geographic 
diversity elements of the physical diversity benchmark. In addition, we 
encourage all CSPs that have taken measures to supply continuous power 
and automatic switchover capability to their covered facilities to 
describe them in their reliability filings, which will enhance the 
Commission's understanding of the status of the NG911 ecosystem.
---------------------------------------------------------------------------

    \286\ See Intrado Comments at 22 (stating it is ``generally 
supportive'' of the proposed operational integrity benchmark, 
agreeing with the Commission's assessment that ``the backup power 
benchmark becomes less significant if the Commission extends the 
physical redundancy requirements to NGCS facilities and location 
services'').
    \287\ See 911 Reliability Order, 28 FCC Rcd at 17514, para. 106.
---------------------------------------------------------------------------

    Requiring continuous power and geographically diverse automatic 
failover capability for applicable CSPs is consistent with CSRIC 
recommendations. In 2019, CSRIC VI updated its best practices for 911 
service providers to recommend, for example, that service providers 
connect power loads at critical sites to on-site generators configured 
to auto[hyphen]engage in the event of commercial power outages.\288\ It 
also noted that service providers should deploy network elements in 
transitional and end-state NG911 networks with redundancy ``for quickly 
swapping network operations onto redundant infrastructure in the event 
of an error within a network element or transmission path'' and that 
automatic and instant failover should include ``redundant standby 
network elements, routers and switches . . . to ensure continuity of 
network services.'' \289\ CSRIC's latest best practices continue to 
reflect these recommendations.\290\ Adding these recommended and 
prevailing practices to the benchmark will help mitigate the

[[Page 42816]]

impact of power outages on NG911 service while streamlining the 
certification process for IP CSPs.

---------------------------------------------------------------------------

    Commenters are generally supportive of this proposal,\291\ although 
some request adjustments. COPUC suggests that we extend the durations 
for backup power at legacy central offices beyond 24-72 hours as 
required under the 2013 reliability rules, but we find that there is no 
CSRIC best practice or basis in the record to prescribe any longer 
duration.\292\ However, we strongly encourage CSPs operating central 
offices to secure additional power reserves from a variety of sources 
(on-site generators, mobile generators and generator delivery services, 
batteries, fuel reserves, etc.) to maximize their resiliency during 
lengthy commercial power outages. We also find it unnecessary to 
subject central offices that do not directly serve PSAPs to backup 
power standards, as one commenter suggested, because such intermediary 
offices likely can reroute 911 calls along physically diverse circuits 
or paths to reach the terminal central office that directly serves the 
PSAP.\293\ In response to NENA's concern that CSP backup power systems 
too often have failed when they were needed, we remind CSPs that, by 
certifying their compliance with the operational integrity benchmark, 
they represent to the Commission that they have properly installed any 
necessary backup power facilities and have conducted all necessary 
testing and maintenance to keep them operational.\294\ We also clarify 
that the benchmark applies only to the offices and network elements 
operated by the CSPs to which the benchmark applies and not to ingress 
or other facilities that are outside of the CSP's control.\295\

Network Monitoring

    As proposed in the NG911 Reliability FNPRM, we update the network 
monitoring benchmark to enable IP-based CSPs to demonstrate the 
reasonableness of their network monitoring measures using 
geographically distributed automatic disruption detection and alarm 
systems.\296\ To qualify, the systems must protect a CSP's IP covered 
facilities, as well as any IP routers, transport nodes, and node links 
it relies on to meet the physical diversity requirement for IP covered 
911 paths. Legacy CSPs may continue to demonstrate reasonable network 
monitoring by using physically diverse monitoring aggregation points, 
monitoring links, and Network Operations Centers (NOCs) and auditing 
the diversity of those facilities annually.\297\ All CSPs retain the 
option to certify that they have adopted alternative network monitoring 
measures or to claim that network monitoring requirements are 
inapplicable to their networks.\298\
---------------------------------------------------------------------------

    \296\ Appendix A (Sec.  9.19(c)(3)).
    \297\ We rename the definition ``aggregation point'' as 
``monitoring aggregation point'' to distinguish the points at which 
monitoring data is aggregated from the points in 911 networks at 
which 911 traffic itself is aggregated, such as selective routers 
and ESInet POIs. See Appendix A (Sec.  9.19(a)(1)).
    \298\ 47 CFR 9.19(c)(3)(ii).
---------------------------------------------------------------------------

    We adopt this modification because the 2013 network monitoring 
benchmark is too restrictive for IP-based CSPs. The Commission created 
the benchmark to respond to monitoring failures in the legacy networks 
of primary 911 service providers during the 2012 derecho and to 
implement CSRIC's recommended best practices for such providers at that 
time.\299\ The 2013 benchmark accordingly requires CSPs to protect 
their monitoring functions by physically separating monitoring 
facilities and the links connecting them to the NOCs where data are 
analyzed. As we have noted, however, IP networks typically do not rely 
on auditing physical wire separation along each individual IP path. IP-
based CSPs therefore have defaulted to certifying and describing their 
network monitoring practices as ``alternative measures'' in their 
filings. Providing a suitable monitoring benchmark for IP CSPs 
streamlines the certification process for providers, more effectively 
supports the reliability of NG911 networks, and improves the Bureau's 
ability to evaluate CSP reliability submissions.

133-134.
---------------------------------------------------------------------------

    We tailor this amended benchmark to reflect CSRIC's recommended 
practices for NG911 service providers and the prevailing architectures 
of modern NG911 networks. CSRIC recommends that NG911 service providers 
``be responsible for monitoring IP connections for transport and for 
capturing network traffic, generating alarms and producing other 
metrics for monitoring and troubleshooting outages within [ESInets], as 
well as those impacting the ability of an [ESInet] to deliver calls to 
the target PSAP.'' \300\ This means that service providers upstream 
from the ESInet should ``monitor for transport alarms associated with 
IP connections to the [ESInet]'' and that, after traffic reaches the 
ESInet POI, service providers should ``be able to detect when IP 
connectivity to the PSAP, or IP connectivity between the first routing 
element in the [ESInet] and other downstream network elements, is 
unavailable'' and ``monitor[ ] IP connections for transport alarms.'' 
\301\ IP networks commonly do this by transmitting ``heartbeat'' 
signals at regular intervals between peer devices that trigger failover 
alarms automatically if heartbeats are not answered.\302\

    Public safety commenters support this revised benchmark, which is 
substantively the same as proposed in the NG911 Reliability FNPRM.\303\ 
They agree that a network monitoring requirement for IP-based CSPs is 
necessary and state that the Commission's proposal reflects the need 
for CSPs to quickly identify and address service disruptions.\304\ 
Lumen acknowledges that the network monitoring requirement serves ``to 
facilitate as soon as possible a provider's response to, and 
notification to others

regarding, an outage potentially affecting completion of 911 calls,'' 
but it argues the NG911 Reliability FNPRM proposal is overly 
prescriptive and that CSPs already employ robust network monitoring to 
comply with their outage notification duties under part 4 of the 
Commission's rules.\305\ We do not believe the network monitoring 
benchmark is overly prescriptive, because it broadly describes 
functional capabilities--automatic disruption detection and alarming--
without specifying a particular architectural solution or product. It 
therefore is consistent with the Commission's technology-neutral 
approach to facilitating reliability in NG911 networks.\306\ We also 
disagree with the assertion that the revised monitoring benchmark is 
duplicative of the part 4 requirement to provide outage notification to 
PSAPs.\307\ The PSAP outage notification rules do not include minimum 
network monitoring standards, and, moreover, do not apply to the new 
classes of CSPs identified in this order. In any event, CSPs with 
monitoring solutions in place can certify them as compliant with the 
benchmark or as alternative measures if necessary.
---------------------------------------------------------------------------

    \303\ The draft rule in Appendix A to the NG911 Reliability 
FNPRM stated that the monitoring requirement would apply to IP CSPs' 
covered facilities. See NG911 Reliability FNPRM, 40 FCC Rcd at 2730. 
The Commission explained in the NG911 Reliability FNPRM that routing 
elements ``responsible for path diversity'' are critical facilities 
in the NG911 ecosystem that should be monitored. See id. at 2695-96, 
para. 68. We include IP routers, transport nodes, and node links 
used to meet the physical diversity requirement for covered 911 
circuits and paths in the benchmark we adopt today for clarity.

Other Benchmarks

    Several commenters urge the Commission to add new reliability 
benchmarks addressing risks stemming from software failures, cyber 
attacks, and privacy breaches, and one initially endorsed the adoption 
of a ``five nines'' (99.999%) reliability standard. We agree that these 
are important considerations, but, at this time, we decline to adopt 
additional benchmarks beyond those proposed in the NG911 Reliability 
FNPRM.
    Software diversity. NENA initially requested that the Commission 
add a software reliability benchmark to combat the rise of software 
defects as ``the single most common cause of NG9-1-1 failure[.]'' \308\ 
It noted that, if components throughout a network are managed by the 
same software, then the software can act a single point of failure and 
disrupt service to an entire NG911 system.\309\ NENA later withdrew its 
request, however, and asked the Commission to investigate software 
errors comprehensively in a different forum.\310\ We agree that 
software failures have emerged as a cause of multi-state outages in 
recent years and that mitigating this threat is a priority.\311\ The 
Commission recently re-chartered CSRIC and tasked it with investigating 
measures that will reduce common causes of ``sunny day'' outages, which 
include internal network failures due to software errors.\312\ We defer 
consideration of this complex issue to a future proceeding, so we can 
develop a better record with contributions from all relevant 
stakeholders.

    Cybersecurity. Several commenters suggest adding a reliability 
benchmark focused on defending against cyber threats.\313\ Attempted 
cyberattacks against the nation's communications networks continue to 
be a major threat, and the Commission is taking steps to mitigate that 
threat through numerous rulemakings and enforcement actions.\314\ We 
will continue to advance the implementation of cybersecurity measures 
in communications networks. We encourage NG911 service providers, OSPs, 
and 911 Authorities to support the cybersecurity of their systems 
during the transition to NG911, and we refer them to recommendations 
and best practices put forward by the Task Force on Optimal PSAP 
Architecture (TFOPA) and CSRIC VII. Both TFOPA and CSRIC VII 
recommended adherence to the widely adopted approach to cyber defense 
detailed in the National Institute of Standards and Technology (NIST) 
Cybersecurity Framework (NCF).\315\ CSRIC VII also recommended that 911 
Authorities implement specific cybersecurity mitigation techniques, 
with, if necessary, the assistance of their NG911 vendors, including: 
continuous cyber monitoring, regular vulnerability assessments, minimum 
backups, a written cyber response plan, cyber-hygiene training, and 
other techniques.\316\ Finally, we encourage NG911 service providers, 
OSPs, and 911 Authorities to leverage resources made available by other 
federal agencies, most notably CISA, to foster and enhance 
cybersecurity and to consider incorporating cybersecurity measures in 
their service agreements.\317\

    Privacy protections. Public Knowledge supports our updated 
benchmarks, but it argues we should require CSPs to comply with 
consumer data privacy and other Customer Proprietary Network

identifies potential cyber breaches of customer data and carrier 
misconduct as risk vectors.\319\ These risks are serious, but they are 
outside the scope of issues addressed in the NG911 Reliability FNPRM.

making unwarranted disclosures of 911-related CPNI.\320\ Because these 
rules protect the

    ``Five Nines'' Reliability. The Commission asked in the NG911 
Reliability FNPRM whether it should incorporate a ``five nines'' metric 
into the 911 reliability framework, referring to a measure of 
reliability equal to 99.999% network availability, which allows only 
5.26 minutes of downtime in a year.\321\ NENA initially indicated its 
support and observed that five nines already is a service level 
requirement in many contracts between 911 Authorities and their NGCS 
vendors.\322\ However, NENA also indicated that NGCS providers often 
cannot achieve this standard; that determining a reliability metric 
across an NG911 network would require CSPs to share proprietary network 
information and to retain outside experts; and that there could be 
disagreements over which types of outages qualify as failures of 
reliability and how to calculate the metric.\323\ NENA later withdrew 
its support and now advises that a five nines requirement for CSPs 
``warrant[s] significant further investigation.'' \324\ We are 
persuaded by NENA's comments and by the overall lack of support in the 
record that it is premature to introduce a five nines requirement at 
this time. However, we strongly support the efforts of 911 Authorities 
to increase the reliability of their NG911 networks by negotiating 
rigorous service level agreements with NG911 CSPs, and we encourage 
other CSPs to adopt the five nines standard as an internal target to 
guide ongoing network performance improvements.

Interoperability

    Today, we adopt a definition of interoperability and require NGCS 
and ESInet CSPs to submit a one-time report describing the actions they 
have taken, and plan to take, to implement interoperability. These 
measures will support the ongoing work of 911 Authorities and their 
industry partners as they strive toward implementing seamlessly 
interoperable NG911 systems. It is essential that NG911 networks enable 
the seamless transfer of 911 calls and data. The ability to reliably 
share, transfer, and validate location data is not just a feature of 
NG9-1-1; it is its foundation.\325\ That is why the Commission defined 
NG911 as a system that ensures interoperability and supports the 
sharing of information related to 911 requests for emergency assistance 
among emergency communications centers and emergency response 
providers.\326\ Interoperable NG911 systems strengthen the resiliency 
and reliability of NG911 services not just during natural disasters, 
outages, and large-scale events,\327\ but also in the provision of 
mutual aid and ensuring fast and efficient handling of 911 calls and 
data.\328\ Interoperability between NG911 systems and providers is a 
key component of the ``end state'' envisioned by TFOPA when it defined 
the stages of the transition to NG911 service.\329\

states of transition ranged from today's legacy state, through 
foundational, transitional, and intermediate states, culminating in 
the jurisdictional and nation-wide ``end states'' of NG911 service. 
Per TFOPA, ``End State'' refers to the state in which PSAPs have 
evolved to become ECCs and are served by standards-based NG911 
systems and/or elements and OSPs are providing SIP interfaces with 
location information during call setup, and ESInets are 
interconnected providing interoperability on a national basis, 
supported by established agreements, policies and procedures.
---------------------------------------------------------------------------

    Based on the record, we find that it is premature to adopt 
substantive interoperability standards and testing requirements at this 
time. In the accompanying Second Further Notice, we seek comment on 
additional proposals to promote greater interoperability across NG911 
systems.

Interoperability Definition

    Defining interoperability is necessary to precisely identify the 
specific operational issues that we intend to address in this 
proceeding. The definition we adopt today is one that envisions a NG911 
ecosystem where 911 Authorities can seamlessly receive, process, and 
share emergency requests across different jurisdictions, technologies, 
devices, and systems. In the NG911 Reliability FNPRM, the Commission 
sought comment on whether a definition of ``interoperability'' was 
needed in order to clarify the obligations of NG911 service 
providers.\330\ Specifically, the Commission sought comment on whether 
the definition of ``interoperability'' from the Spectrum Auction 
Reauthorization Act of 2023 (H.R. 3656) \331\ would help to define the 
scope of any future interoperability requirements.\332\
---------------------------------------------------------------------------

    \330\ NG911 Reliability FNPRM, 40 FCC Rcd at 2699, para. 80.
    \331\ H.R. 3565 defines the term ``interoperability'' as the 
capability of emergency communications centers to receive 9-1-1 
requests for emergency assistance and information and data related 
to such requests, such as location information and callback numbers 
from a person initiating the request, then process and share the 9-
1-1 requests for emergency assistance and information and data 
related to such requests with other emergency communications centers 
and emergency response providers without the need for proprietary 
interfaces and regardless of jurisdiction, equipment, device, 
software, service provider, or other relevant factors.

    Commenters generally support adopting an interoperability 
definition that tracks language in proposed legislation, with minor 
variations. APCO states that ``the public safety community has 
developed a definition of interoperability that reflects its 
operational needs and that has been incorporated into legislative 
proposals,'' and urges the Commission to adopt this definition.\333\ 
ATIS urges the Commission to adopt a formal definition of 
``interoperability'' in the context of NG911.\334\ NENA advocates using 
the definition included in H.R. 1784--Next Generation 9-1-1 Act of 
2023,\335\ while T-Mobile proposes a definition that is

[[Page 42819]]

similar to the two proposed legislative definitions.\336\

---------------------------------------------------------------------------

    Given the relatively slight differences between the various 
proposed definitions, we adopt the following definition that aligns 
with the consensus reflected in H.R. 3565 and is designed to promote 
interoperability and discourage proprietary features:
    The technical and operational capability of NG911 service providers 
to exchange 911 voice, text, data, and multimedia between 
jurisdictions, PSAPs, ECCs, and other service providers, in real time 
without the need for proprietary interfaces and regardless of 
jurisdiction, equipment, device, software, service provider, or other 
relevant factors.\337\
---------------------------------------------------------------------------

    \337\ Appendix A (Sec.  9.19(a)(19)).
---------------------------------------------------------------------------

    This definition, while substantially similar to the H.R. 3565 
definition, is intended to encompass the entire call flow from 
initiation through resolution while remaining technologically neutral. 
Technological neutrality is important to ensure this definition remains 
relevant as the technological capabilities of NG911 expand and evolve. 
We also add ``NG911 service providers'' to the definition of 
interoperability in acknowledgement of the technical limitations of 
legacy 911 systems and to signal our intent to apply interoperability 
requirements only to NG911 systems.

One-Time Reporting Requirement

    We require NGCS and ESInet providers, which have a direct role in 
enabling interoperability as defined in this Order, to submit a one-
time report to the Commission describing the specific actions they have 
taken, as well as their plans for future actions, to enable NG911 
interoperability consistent with that definition.\338\ We allow 18 
months to submit this report to provide CSPs adequate time to assess 
their interoperability capabilities, document existing interoperability 
arrangements, and prepare accurate reports.\339\ This reporting 
requirement is intended to encourage these entities to prioritize and 
accelerate their interoperability efforts, while providing the 
Commission with a greater understanding of the overall progress of 
interoperability across the entire NG911 ecosystem. We believe these 
reports will promote continued focus on interoperability issues as part 
of the NG911 transition and will provide us with important information 
on whether any additional interoperability requirements are needed to 
advance the transition.\340\
---------------------------------------------------------------------------

    \338\ See Appendix A (Sec.  9.20(b)).
    \339\ Entities that begin providing covered 911 services after 
the interoperability reporting deadline must submit a one-time

---------------------------------------------------------------------------

    Commenters note that facilities interconnecting ESInets are only 
one type of facility needed to ensure interoperability for interstate 
911 live call transfers across multiple touchpoints in NG911 systems 
(e.g., ESInet to ESInet, NGCS to NGCS, PSAP to PSAP).\341\ We agree 
that achieving full interstate NG911 interoperability will require more 
than ESInet-to-ESInet interoperability alone. Nevertheless, given that 
this is the first time the Commission has adopted 911 interoperability 
measures, and in order to maximize public interest benefit impact with 
the least amount of regulatory burden, we are limiting the 
applicability of the reporting requirement to NGCS and ESInet 
providers. These entities supply critical call routing and transfer 
services that enable the connection between an NG911 call initiator and 
an NG911 PSAP. We believe focusing on these providers is not only a 
significant step forward towards increased interstate interoperability; 
we also anticipate that this step will incentivize the further 
development of interoperability solutions in other aspects of the NG911 
ecosystem, including local and intrastate interoperability.\342\

Interoperability Benchmarks and Testing

    Benchmarks. We decline, in this Order, to mandate specific 
interoperability benchmarks or testing requirements. In the NG911 
Reliability FNPRM, we proposed to require that CSPs certify whether 
their interstate interconnecting ESInet facilities achieve 
interoperability for exchanged 911 traffic sufficiently to enable 
complete interstate transfers between ESInets or certify to alternative 
measures.\343\ However, there was considerable disagreement in the 
record with regards to the need for, efficacy of, and scope of our 
proposed interoperability certification requirements.\344\ Commenters 
generally agree that interoperability is critical to the success of 
NG911 but disagree on the timing of regulatory action and whether 
industry-led standards development could supplant the need for 
Commission action. Industry commenters and standards bodies argue that 
the Commission should either delay establishing a requirement pending 
further study or defer establishing a requirement altogether and allow 
interoperability solutions to evolve as a natural result of market 
forces.\345\ Public safety commenters urge the Commission to act now as 
delay will only embed existing incompatibilities.\346\
---------------------------------------------------------------------------

    \343\ NG911 Reliability FNPRM, 40 FCC Rcd at 2697, para. 72. We 
proposed requiring CSPs to certify whether their NGCS and/or ESInet 
facilities use conformance-tested equipment and whether they have 
tested their interstate interoperability capabilities. We further 
proposed allowing CSP to certify in the alternative: (1) whether it 
(or its ESInet facility operator) has taken alternative measures to 
ensure interoperability between ESInets in multiple states and 
between providers; (2) whether it believes that one or more of the 
requirements of this paragraph are not applicable to its facilities; 
and (3) to additional questions about the non-conforming facilities

    Collectively, the record reflects that 911 Authorities and CSPs 
have begun to take steps to enable interoperability between NG911 
systems, but that this work is still in its very early stages.\347\ 
Demonstrated interoperability sufficient to permit policy routing and 
seamless transfer of NG911 traffic across jurisdictional boundaries is 
still the exception rather than the norm, and capabilities to enable 
cross-jurisdictional dispatch are even more rare.\348\ Given that this 
subject remains unsettled, we decline to adopt interoperability 
standards at this time.

    Given the lack of foundation in the record that would be needed to 
establish a meaningful testing regime, we find it neither prudent nor 
productive to impose testing or associated certification requirements 
at this time. However, in order to facilitate reporting and inform 
future work on NG911 interoperability, we adopt definitions of 
``interoperability standards testing'' and ``interoperability 
conformance testing.'' In the companion Second Further Notice, we seek 
comment on further steps to promote interoperability, including 
empowering our state partners to develop mechanisms enabling them to 
craft the level of interoperability that they believe appropriate to 
their state.\353\

Oversight

    As proposed in the in the NG911 Reliability FNPRM, we adopt 
targeted updates to strengthen the oversight of 911 reliability and 
interoperability by the Commission and by 911 Authorities while 
lessening compliance burdens on CSPs.\354\ First, we replace annual 
reliability certifications with a one-time initial certification and a 
continuing obligation to update that certification following any 
material change. We also direct the Bureau to streamline the form that 
CSPs will use to submit their reliability certifications and to update 
it to reflect the changes to the 911 reliability framework we adopt 
today. Second, we grant state, territorial, and tribal 911 Authorities 
access to CSPs' reliability certifications and interoperability 
reports, conditioned on their adherence to robust confidentiality 
safeguards. And third, to provide transparency to CSPs, we codify the 
administrative process the Bureau will follow in the event it becomes 
necessary to remediate a CSP's noncompliance with its 911 reliability 
obligations. We decline to adopt several oversight proposals from the 
FNPRM, including the creation of a new portal for consumer complaints 
and a petition process for 911 Authorities, because we find them to be 
unwarranted at this time.

---------------------------------------------------------------------------

Reliability Certification Process

    We update the reliability certification process to ensure continued 
CSP accountability while reducing regulatory burdens. First, we 
eliminate the requirement for CSPs to file reliability certifications 
annually. We conclude that annual filing is not an effective means of 
obtaining timely and actionable information regarding network 
reliability and that it results in needless annual reporting burdens 
for CSPs when there may be no material changes to their networks or 
reliability practices from year to year. Going forward, CSPs will only 
be required to submit an initial compliance certification and to update 
it in the event of a material change to the information covered by the 
certification.
    Second, we eliminate the requirement for certifications to 
separately document reliability practices with respect to each 
individual PSAP served by the CSP. While this level of detail may have 
been appropriate for ensuring reliable connectivity between legacy 
selective routers and TDM-based PSAPs, IP-based CSPs typically 
implement reliability measures at the network or service-platform 
level. For example, where an ESInet provider incorporates physical 
diversity and enables dynamic rerouting of calls among multiple PSAPs, 
requiring reliability certifications on a per-PSAP level yields little 
unique information while imposing significant administrative burdens. 
We therefore allow CSPs to file consolidated certifications for their 
facilities at the network level, provided that facilities serving 
multiple states are identified on a per-state basis to facilitate 
evaluation by 911 Authorities.
    Third, the updated certification process provides relief for IP-
based CSPs that previously certified to common IP reliability practices 
as ``alternative measures,'' which required them to include narrative 
explanations and justifications in their certifications. These measures 
are now specifically identified as best practices that meet the 
reliability benchmarks of the updated rules. Accordingly, CSPs may 
certify to their use without the need for lengthy narrative 
explanations or other burdensome filing requirements.
    Going forward, under the updated certification process we adopt 
today, CSPs will submit a one-time certification addressing the three 
elements of reliability (physical diversity, operational integrity, and 
network monitoring) and, thereafter, file updated certifications only 
on an as-needed basis. To provide time for compliance with the new 
reliability benchmarks, CSPs will not need to file the initial 
certification until 18 months after a public notice announcing a 
compliance date.\355\ CSPs must also update their certifications within 
90 days of discovery of any material change to their ownership 
structure, networks, facilities, operations, or reliability practices 
that renders the prior certification inaccurate or incomplete. This 
approach minimizes the burden on providers while ensuring that the 
Commission has the benefit of an accurate, up-to-date record of the 
reliability practices that are protecting 911 connectivity.\356\ We 
emphasize that the purpose of the certification requirement is to 
ensure that the Commission and relevant 911 Authorities have accurate 
and current information regarding CSP reliability practices. Therefore, 
CSPs are responsible for exercising reasonable judgment in determining 
whether a change is material and ensuring that their certifications are 
complete, accurate, and up to date at all times.\357\
---------------------------------------------------------------------------

    \355\ Entities that begin providing covered 911 services after 
that initial certification compliance date must submit an initial 
reliability certification when they begin providing services.
    \356\ See NENA Comments at 19 (encouraging the Commission to 
``simplify reporting requirements'' while maintaining ``a complete 
picture of what happened, and any corrective actions to be taken'').
    \357\ As under the previous rules, certifications must be signed 
by an official under penalty of perjury as to the accuracy of their 
contents. See Appendix A (Sec.  9.19(a)(2)).
---------------------------------------------------------------------------

    We agree with USTelecom that ``material changes'' should exclude 
changes remedied within 90 days of discovery and pro forma ownership 
changes, and that carriers should exercise reasonable judgment about 
when an update is required.\358\ We also agree with USTelecom that 
frequent updates for network improvements would be burdensome to CSPs 
and not helpful for oversight,\359\ and we therefore exclude 
improvements for less

[[Page 42821]]

than 50 percent of a CSP's covered 911 services, circuits, and paths. 
This will eliminate excessive filings while preserving reasonable 
awareness of major network reliability improvements. CSPs are free to 
file more frequent updates for lower threshold improvements, either on 
their own or upon agreement with a 911 Authority, including targeted 
updates for improvements limited to specific states or regions.

    We also require CSPs covered by the updated rules that have not 
previously filed a reliability certification to file an attestation 
identifying themselves as covered 911 service providers.\360\ 
Attestations will be due six months after the Bureau issues a public 
notice announcing the commencement of the 18-month transition period 
for coming into compliance with the updated reliability rules. The 
attestations will enable the Commission and 911 Authorities to identify 
the scope and number of CSPs participating in the NG911 ecosystem 
before CSPs submit their initial reliability certifications.

    Consistent with the NG911 Reliability FNPRM, we direct the Bureau

revisions to the 911 reliability framework and to make general 
improvements to the form.\361\ We delegate authority to the Bureau to 
make such changes to the form as are needed to streamline the process 
for providers and to collect data in formats that will allow Bureau 
staff to easily sort and analyze it.\362\ We also direct the Bureau to 
implement streamlined filing requirements by revising the instructions 
to facilitate certifications consistent with today's framework, and 
with the goal of reducing compliance burdens on regulated entities.

    Reporting 911 call volume. At this time, we do not require CSPs to 
report the volume of 911 call traffic that their non-conforming 
facilities handle.\363\ The Commission proposed this addition in 
response to previous comments from state government entities in other 
proceedings.\364\ While information regarding CSPs' 911 call volumes 
could be beneficial to enable the Bureau to better identify and address 
areas that are exposed to outsized risk of major disruptions to 911 
service,\365\ the record shows that collecting this data may be 
technologically infeasible for some CSPs at this time or would require 
significant cooperation from vendors and PSAPs.\366\
---------------------------------------------------------------------------

    Certification regarding leased facilities. Several industry 
commenters urge the Commission to limit NG911 CSPs' certification 
responsibility to the network elements they operate themselves and to 
exclude the transport paths and functional elements they lease from 
third parties. These commenters claim that their third-party providers 
have too much market power and refuse to share information with them 
about their networks' path diversity.\367\ APCO, on the other hand, 
argues that CSPs ``must be accountable for the actions of their third-
party contractors, including the measures those parties take to 
maintain reliability,'' and NENA supports this view.\368\

that a 911 Authority's NGCS vendor should be responsible for

---------------------------------------------------------------------------

    The Commission's longstanding practice has been to require CSPs 
that lease transport or other facilities to certify how they meet their 
reliability obligation through their leased facilities.\369\ We see no 
basis to change this practice. Our updated designation of key NG911 
service providers as CSPs in today's Order will provide additional 
transparency with respect to their reliability practices. We expect 
OSPs, CSPs, 911 Authorities, and their vendors to collaborate as needed 
to facilitate compliance with our 911 reliability framework and to 
support a strong, resilient, and interoperable NG911 ecosystem. With 
respect to certification, CSPs that lease or otherwise rely on third-
party facilities should certify to network practices within their 
control and may cite to representations provided by third parties in 
service level agreements. In cases where a CSP cannot obtain necessary 
information from a third party it uses to provide NG911 service, the 
CSP should describe in its certification the efforts it made to obtain 
the information and why those efforts were unsuccessful. The Commission 
will take these circumstances into consideration when evaluating the 
sufficiency of the CSP's certification.\370\
---------------------------------------------------------------------------

Rcd at 8657, para. 17 (``[T]he contracting out of certain functions 
. . . does not absolve individual [CSPs] of their respective 
obligations for reliable 911 service.''). See also 47 U.S.C. 217 
(``[T]he act, omission, or failure of any officer, agent, or other 
person acting for or employed by any common carrier or user, acting 
within the scope of his employment, shall in every case be also 
deemed to be the act, omission, or failure of such carrier or user 
as well as that of the person.'').
    \370\ Because each CSP will certify the reliability of its own 
facilities and any subcontracted or leased facilities it uses to 
provide 911 service, we find that there is no cause for CSPs to 
submit a ``chain-of-responsibility matrix'' on behalf of their 
subcontractors, as two commenters proposed. See CCOA Comments at 4; 
Lumen Reply at 7-8.
---------------------------------------------------------------------------

    Other changes to the certification process. We do not find 
sufficient support in the record to change the certification process in 
other ways that some commenters suggest.\371\ Home Telephone, for 
example, advocates requiring ESInet operators to prove their financial, 
technical, and managerial resources and receive advance certification 
from the Commission before they may provide services to 911 
Authorities.\372\ We decline to take this step because 911 Authorities 
have the ability to require such disclosures when soliciting bids from 
potential ESInet providers, and, as Lumen observes, ``the record 
contains no allegations[] of ESInet providers [being] chronically 
unprepared to provide service

[[Page 42822]]

successfully.'' \373\ We also see no need, at this time, to require 
CSPs to submit to periodic third-party testing and audits to confirm 
the accuracy of their reliability certifications.\374\ While we 
encourage CSPs to perform periodic testing and auditing, and while 911 
Authorities have discretion to include testing and auditing provisions 
in their contracts with CSPs, requiring such measures by rule could 
greatly increase the cost of compliance and we prefer to permit 
flexibility for any testing and auditing measures that support accurate 
reliability certifications.

---------------------------------------------------------------------------

    Simplifying regulatory language. We adopt minor amendments to the 
regulatory text implementing our 911 reliability framework to improve 
clarity and thereby reduce compliance burdens on covered entities.\375\ 
Specifically, we consolidate the certification and other filing 
requirements that formerly appeared across former Sec. Sec.  9.19(c)(1) 
through 9.19(c)((3) and move them to a new Sec.  9.20, entitled 
``Reliability and Interoperability Certifications; Cessation Notices.'' 
This change simplifies Sec.  9.19, which now relates solely to CSPs' 
substantive obligations to provide reliable 911 services. Section 9.20 
now addresses procedural matters associated with the reliability 
requirement, including certifications, confidentiality, record 
retention, cessation notices, and remedial actions. We also have made 
non-substantive, streamlining changes to certain regulatory language, 
including to the record retention subparagraphs under former Sec.  
9.19(d)(3), as proposed.\376\

911 Authority Access to Certifications and Reports

    We adopt, with some modifications, the Commission's proposal to 
ensure that 911 Authorities can access CSP reliability certifications 
and interoperability reports.\377\ The Commission has long recognized 
that 911 Authorities should have access to CSPs' submissions to inform 
their planning and oversight of the 911 networks serving their 
jurisdictions. When the Commission adopted the 2013 reliability rules, 
it recognized that PSAPs and 911 Authorities ``have a strong interest 
in obtaining relevant information about the reliability and resiliency 
of their 911 service'' and might need additional information ``to 
prompt [CSPs] to make specific reliability improvements in their 
networks.'' \378\ The Commission did not mandate disclosure to PSAPs or 
911 Authorities at that time ``[i]n light of the wide variety of 
circumstances involved in how PSAPs nationwide purchase 911 service,'' 
but it admonished CSPs to ``respond promptly'' to disclosure requests 
and to ``enter into discussions concerning the content of the 
provider's 911 circuit auditing certification.'' \379\ The Commission 
concluded ``that PSAPs should have access to the details of circuit-
auditing certifications, as long as the sensitive and proprietary 
nature of the information can be maintained.'' \380\

circuit routes to the PSAP.'').
    \380\ Id. at 17533, para. 158.
---------------------------------------------------------------------------

    The record in this proceeding indicates that disclosure of CSP 
reliability certifications and interoperability reports is more 
critical today than in 2013, because the NG911 ecosystem now involves a 
wider array of providers, traffic aggregators, and subcontracted 
facilities that may not have direct relationships with the PSAPs and 
911 Authorities whose 911 traffic they process and carry. The 
increasingly diffuse nature of the NG911 ecosystem makes it more 
difficult for 911 Authorities to fully assess the reliability and 
interoperability of their 911 services without access to provider 
network information, especially from distant CSPs that provide NG911 
capabilities on the OSP side of the NG911 ecosystem.\381\

---------------------------------------------------------------------------

    Public safety and industry commenters broadly agree that 911 
Authorities should be entitled to access CSP submissions, subject to 
confidentiality protections.\382\ Commenters note that ``[t]he 911 
community is currently lacking access in this area and [that] having 
access to information about covered service providers' certifications 
would be extremely useful. Knowledge of the points of vulnerability in 
the 911 network serving a state or an individual PSAP will help state 
and local 911 officials better plan for and mitigate the risks of 
outages and disruptions.'' \383\ CCOA agrees that ``[f]or their advance 
operational planning, 911 Authorities must be able to rely on the CSP's 
identification of where critical 911 circuits are diverse and where 
they are not.'' \384\ Lumen notes that the Commission's proposal is 
``undergirded by appropriate safeguards and already-existing 
processes'' and is cabined appropriately to government entities ``with 
a need-to-know basis.'' \385\

    Given the strong and consistent responses of most commenters, we 
are not persuaded by Verizon's dissenting view that 911 Authorities do 
not want or need access to 911RCS filings.\386\ Nor do we agree that 
CSPs should be permitted to redact descriptions of their alternative 
measures and other ``specific technical details,'' as one commenter 
suggests.\387\ That is precisely the type of information 911 
Authorities need to identify potential single points of failure and 
other vulnerabilities, and we believe the confidentiality and redaction 
protections we adopt today are sufficient to avoid unnecessary 
disclosures of network information. As one provider puts it: ``As we 
evolve our 911 system into the NG911 environment[,] . . . local PSAPs 
lose visibility into the reliability of many of the elements required 
for the functioning of the system. Importantly[,] our local PSAPs and 
even our State 911 Authorities lose visibility in the

[[Page 42823]]

operations of national NG911 ESInet aggregators as well as national 
transport providers.'' \388\ In this more complex environment, we find 
that voluntary disclosure is no longer sufficient to ensure that 911 
Authorities consistently receive all of the information they need to 
safeguard the reliability of the 911 systems they oversee.\389\
---------------------------------------------------------------------------

    \386\ Verizon Comments at 16 (``To date there has been very 
little demand by state and local government 911 authorities for 
wireline 911 providers' annual certifications[.]''). Verizon's 
observation, if true, could be due to 911 Authorities' focus in 
recent years on transitioning away from legacy wireline 911 services 
to NG911. These efforts underscore the need for 911 Authorities to 
have access to the certifications of IP-based CSPs.

    \389\ We acknowledge that some 911 Authorities may already

---------------------------------------------------------------------------

    Separately, we conclude that providing 911 Authorities with access 
to CSP reliability and interoperability filings will amplify the 
Commission's ability to address potential risks to NG911 service and 
possible violations of the Commission's 911 reliability framework.\390\ 
Although the Commission is ultimately responsible for enforcement of 
its framework, 911 Authorities have a shared interest in protecting the 
reliability of NG911 networks, and we believe their oversight will 
complement our own. 911 Authorities are better positioned than the 
Commission, in some cases, to identify compliance issues, because they 
are customers of NG911 services and regularly coordinate with CSPs 
regarding service problems. Enabling 911 Authorities to report concerns 
to the Bureau therefore will improve the Commission's oversight while 
conserving Bureau resources and freeing staff to focus their attention 
on critical risks that could result in multistate and multi-OSP outages 
or hamper interstate interoperability.
---------------------------------------------------------------------------

    \390\ See, e.g., NYSPSC Comments at 2 (``[T]he availability of 
this information will also better position state and local 911 
authorities to offer more substantive and effective recommendations 
to the FCC in future NG911 proceedings.''); see also Washington 
Utilities and Transportation Commission Comments, PS Docket No. 14-
193 at 8 (filed March 17, 2015) (``Access to such information by 
state officials would greatly assist in understanding and tracking 
marketplace developments affecting 911 service delivery within the 
scope of their jurisdictions. State access could also greatly assist 
officials during times of emergency . . . in understanding and 
interacting with such entities as events unfold.'').
---------------------------------------------------------------------------

    Confidentiality protections. As proposed in the NG911 Reliability 
FNPRM, we retain the presumption of confidentiality for proprietary 
information in reliability certifications, and we require 911 
Authorities seeking access to CSP reliability certifications and 
interoperability reports to comply with the same confidentiality 
safeguards that protect NORS outage reports when state agencies are 
given access to them.\391\ The Commission allows state, territorial, 
and tribal agencies to access NORS reports on a need-to-know basis, 
conditioned on their agreement to robust confidentiality 
protections.\392\ The NORS protections are set forth in their entirety 
through the codified provisions in Sec.  4.2 of part 4 of the 
Commission's rules and the guidance, instructions, and forms the Bureau 
has published on the Commission's website.\393\
---------------------------------------------------------------------------

    \391\ See NG911 Reliability FNPRM, 40 FCC Rcd at 2708, para. 
101; 47 CFR 9.19(d)(2)(i), (ii) (confidentiality of 911RCS 
certifications).

Disruptions to Communications, PS Docket No. 15-80, Second Report 
and Order, 36 FCC Rcd 6136, 6137, para. 3 (2021) (NORS Information 
Sharing Order). See also id. at 6143-97, paras. 22-128 (summarizing 
confidentiality protections).
    \393\ See 47 CFR 4.2; FCC, Outage Information Sharing, https://www.fcc.gov/outage-information-sharing (last visited May 19, 2026)

Certification Form''). See also NORS Information Sharing Order, 36 
FCC Rcd at 6143-97, paras. 22-128 (explaining the NORS access rules 
and procedures).
---------------------------------------------------------------------------

    We find that the NORS data protections are an appropriate and 
effective model for safeguarding reliability certifications and 
interoperability reports. The NORS framework reflects a mature, field-
tested set of safeguards that already balances state and tribal 
agencies' need for operationally meaningful network information with 
the imperative to protect service providers' proprietary data. Aligning 
the confidentiality obligations for NORS reports and reliability 
certifications and interoperability reports likewise reduces 
administrative uncertainty for both agencies and providers, promotes 
consistent treatment of sensitive reliability information across 
Commission programs, and preserves strong incentives for CSPs to 
participate fully and candidly in the certification process.
    Accordingly, we permit CSPs to condition their production of 
reliability certifications and interoperability reports to 911 
Authorities on their execution of confidentiality agreements with terms 
that are not more restrictive than those set forth in Sec.  4.2 and the 
Bureau's supplemental guidance.\394\ We also clarify that only 
statewide, territorial, and tribal 911 Authorities may request copies 
of CSPs' certifications and reports. While we recognize that allowing 
local or regional 911 Authorities to access CSP certifications and 
reports could also be beneficial in some instances--particularly in 
home rule states where such entities have responsibilities for NG911 
planning and deployment decisions--we find that extending access to 
potentially hundreds of government entities would impose undue burdens 
on CSPs and could result in an unwarranted proliferation of their 
sensitive and proprietary information.\395\ Moreover, states have the 
option of using centralized emergency services planning or regulatory 
bodies to issue the requests and then coordinating with local agencies 
and sharing information when necessary, consistent with Sec.  4.2. This 
approach also aligns with our determination to permit filing 911 
reliability certifications at the level of a given state or territory, 
rather than on the previous PSAP-by-PSAP level.

the Commission ``reinforce that access to these certifications would 
be limited to `911 Authorities' and not `state and local 
governments' writ large'').
---------------------------------------------------------------------------

    We further clarify that certain of the NORS procedures for 
accessing information may not apply in every circumstance in the 911 
reliability context. For example, rules governing agencies' account 
access to the NORS database will not apply unless and until the Bureau 
establishes a pathway for direct 911 Authority access to any new 
reliability database. Instructions pertaining to agency submissions to 
the Bureau also will not apply, because our framework implements a 
process carried out through the cooperation of CSPs and 911 
Authorities. We believe that CSPs and 911 Authorities, working together 
in good faith, will be able to adapt the NORS procedures to their 
specific circumstances straightforwardly, altering them by mutual 
agreement as necessary. And consistent with the NORS framework, the 
Bureau may use its delegated authority to terminate a 911 Authority's 
right of access to CSP certifications for a period of time, among other 
measures, if the 911 Authority violates its confidentiality 
obligations.\396\
---------------------------------------------------------------------------

    \396\ See 47 CFR 4.2(e); 47 CFR 0.392(j).
---------------------------------------------------------------------------

    Access procedures. State, territorial, and tribal 911 Authorities 
may obtain copies of filings submitted by the CSPs that provide them 
with covered services or that operate covered 911 circuits or paths 
located within their jurisdictions. A 911 Authority may request copies 
from CSPs directly, in which case the CSP must comply within 14 days, 
provided the 911 Authority signs a confidentiality agreement that is 
consistent with the confidentiality

[[Page 42824]]

protections for reports filed in NORS.\397\ CSPs may omit or redact 
information relating to portions of their networks or facilities that 
do not provide covered services to, and are not located in, the 
requesting 911 Authority's jurisdiction. CSPs' obligation to produce 
certifications and reports to 911 Authorities will commence following 
the announced deadline for submitting such certifications and reports.
---------------------------------------------------------------------------

    \397\ See 47 CFR 4.2.
---------------------------------------------------------------------------

    We also authorize state, territorial, and tribal 911 Authorities to 
obtain certifications and reports filed in 911RCS from the Bureau.\398\ 
We direct the Bureau to provide instructions, updated as necessary, to 
911 Authorities regarding access to such filings.\399\ To conserve 
Commission resources, we allow 911 Authorities to obtain certifications 
from the Bureau only after attempting to obtain them directly from 
CSPs, and we will not require Bureau staff to redact CSP filings. For 
the same reason, we reject requests from several commenters that the 
Commission should make itself the only source from which 911 
Authorities can obtain CSP certifications.\400\

Remediation Process

    In the NG911 Reliability FNPRM, the Commission proposed to codify 
the remediation process by which the Bureau addresses apparent 
deficiencies in CSP reliability certifications.\401\ Although the 
Bureau already has delegated authority to conduct remediation, the 
Commission suggested that adopting codified procedures would make the 
remediation process more transparent and predictable.\402\

    \402\ Id.
---------------------------------------------------------------------------

    We find that codification of our remediation procedures will 
increase awareness of how the Bureau determines violations of Sec.  
9.19(b) and of providers' ability to contest such findings. No 
commenters oppose codification, and COPUC strongly supports the 
proposed procedures.\403\ COPUC also proposes that the codified 
procedures provide for 911 Authorities to receive copies of all Bureau 
remediation notices provided to CSPs in their jurisdictions \404\ We 
agree with COPUC's proposal and include it in the codified procedures.

    When the Bureau identifies apparent noncompliance with the 
requirement for CSPs to provide reliable 911 service, it ordinarily 
will try to work with the provider and other interested stakeholders 
(e.g., affected PSAPs) to address any shortcomings.\405\ The Bureau 
also may order the provider to take remedial action.\406\ We codify the 
following remediation procedures that the Bureau and CSPs will follow 
in such cases: \407\

---------------------------------------------------------------------------

     Notice. If a CSP's certification or other information 
indicates that it may not have taken reasonable measures as required by 
Sec.  9.19(b), the Bureau may issue and electronically serve on the CSP 
a notice describing its apparent deficiencies and any remedial actions 
the Bureau proposes. The notice may include requests for relevant 
documents and information.
     Response. The CSP must provide any requested documents and 
information to the Bureau within 30 days. It may also submit a written 
response to the notice.
     Order. At any point after the 30th day following its 
service of the notice, the Bureau may issue and serve on the CSP an 
order setting forth its findings and specifying the remedial actions 
the CSP must take. The order also may set deadlines for the required 
actions and identify information the CSP must submit to demonstrate its 
compliance with the order.
     Notice to 911 Authorities. The CSP must deliver a copy of 
the Bureau's order promptly to the 911 Authority for each jurisdiction 
in which its reliability measures were found deficient or in which it 
was directed to take remedial actions.\408\
---------------------------------------------------------------------------

    \408\ See Appendix A (Sec.  9.20(g)); COPUC Comments at 12 
(``The 911 Authority is in the best position to monitor the activity 
of the CSP to ensure that it is complying with the Bureau's order, 
but only if it knows that such an order exists.'').
---------------------------------------------------------------------------

    This process accurately reflects current practice, and it falls 
within the broad scope of the authority the Commission already has 
delegated to the Bureau.\409\ We also clarify that the newly-codified 
process described above applies solely to the remediation of violations 
of Sec.  9.19(b) by the Bureau and does not limit the Bureau's general 
administrative authority over the 911 reliability framework or 
constrain the Bureau's ability to take other enforcement or oversight 
actions pursuant to its delegated authority. Nor does the remediation 
process constrain the Commission's broader adjudication or enforcement 
authorities, including its statutory powers to enforce its orders and 
to assess forfeitures, whether on referral from the Bureau or 
otherwise.\410\

Other Issues

    Consumer portal and petition process. In the NG911 Reliability 
FNPRM, the Commission sought comment on establishing a new consumer 
portal dedicated to 911-related outage reports and a new petition 
process for 911 Authorities to allege CSP violations of the 911 
reliability framework and interoperability measures.\411\ The 
Commission suggested these mechanisms as potential complements to the 
existing avenues through which consumers and 911 Authorities already 
may report 911 reliability issues to the Bureau's attention.\412\ On 
review of the record, however, we decline to adopt these proposals.

---------------------------------------------------------------------------

    Comments are mixed in favor of and against establishing a new 
petitions process or a dedicated consumer portal. Supporters argue that 
a new petition process would encourage frank exchanges between 911 
Authorities and CSPs and that a new consumer portal would increase 
transparency and enhance communication between the Commission and the 
public.\413\ However, a number of commenters, including Verizon, 
Intrado, and CTIA, believe that a petition process would be

[[Page 42825]]

more likely to spoil coordination and cooperation among stakeholders 
and undermine the ability of Bureau staff to have candid and 
constructive discussions with providers.\414\ They also contend that 
the new complaint mechanisms would be duplicative of existing avenues 
through which concerns about 911 service and CSP compliance can be 
raised, including the Public Safety Support Center (for PSAPs and 911 
Authorities), the Consumer Inquiries and Complaints Center (for 
individual consumers), and the Commission's general petition 
process.\415\ CTIA argues that the new mechanisms therefore would 
impose substantial costs without significant countervailing public 
benefits.\416\

---------------------------------------------------------------------------

    We are persuaded that consumers and 911 Authorities can provide 
significant value by identifying localized reliability concerns and 
assisting the Commission's oversight of NG911 networks, but we conclude 
that these benefits can be fully achieved through the Commission's 
existing reporting avenues and informal referral processes. Rather than 
create new procedural mechanisms, which the record shows could impose 
unnecessary burdens, we will continue to rely on these established 
channels to facilitate communication, surface potential violations, and 
support cooperative engagement between the Bureau, CSPs, 911 
Authorities, and the public. To ensure that our existing channels are 
used to their greatest benefit, we instruct the Bureau to consider 
undertaking targeted outreach and engagement efforts to raise awareness 
of these avenues and to encourage 911 Authorities and consumers to use 
them to refer concerns relating to the reliability of covered 911 
services.
    Cessation notices. We do not adopt the Commission's proposal to 
require CSPs to notify 911 Authorities, at the same time they notify 
the Commission, when they cease providing covered 911 services.\417\ 
Under the previous 911 reliability rules, CSPs must file a notification 
with the Commission under penalty of perjury no later than 60 days 
after their cessation of service.\418\ The cessation notifications to 
the Commission become due ``only when a [CSP] completely ceases 
providing covered 911 services'' and not whenever it ceases to provide 
service to a particular PSAP or jurisdiction.\419\ Accordingly, only 
the last jurisdiction where a CSP retires its last covered 911 service 
or facility would receive the notice. We therefore find that the 
limited potential benefit to 911 Authorities from receiving the 
notifications would not outweigh the additional burden on all CSPs to 
maintain awareness of a new notification requirement. We note as well 
that no commenters responded to this proposal in the record.

    PSAP Outage Notifications. Finally, we note that Sec.  4.9(h) of 
the rules incorporates section 9.19's definition of ``covered 911 
service provider'' in defining the providers that must notify 911 
special facilities about certain outages. We decline at this time to 
extend the section 4.9(h) reporting obligation to those entities that 
are newly designated as CSPs by this Order.\420\ Several commenters 
contend that requiring newly-designated CSPs to provide outage 
notifications to PSAPs is unnecessary or possibly counterproductive, as 
it could lead to duplicative notifications to PSAPs.\421\ It is also 
unclear from the record whether it is technically feasible for 
operators of multi-OSP LISs and LNGs, major IP transport facilities, 
and IP 911 traffic aggregation facilities to notify 911 special 
facilities about outages that potentially affect them as our rules 
require. Because the current record is mixed and does not contain a 
thorough discussion of these issues, we agree with commenters that 
further consideration is warranted and therefore do not require these 
operators to report at this juncture.\422\ We note that cable, 
satellite, wireless, legacy wireline, interconnected VoIP, as well as 
covered 911 service providers (as previously defined), continue to have 
a non-delegable duty to provide notification to 911 special facilities 
under our rules, and that reliance upon a third party to contribute to 
911 call processing does not relieve the provider of that duty.\423\

Compliance Timelines

    We establish an 18-month transition period for phasing in our new 
911 reliability framework and interoperability measures. We find that 
this transition period is justified to avoid excessive costs, allow 
operational flexibility, and provide time for stakeholders to gain 
experience with implementing reliability measures and interoperability 
arrangements in NG911 networks as deployments continue to mature.\424\ 
The 18-month period will commence when the Bureau issues a public 
notice announcing approval by the Office of Management and Budget (OMB) 
of the information collection requirements adopted in this Order. Newly 
designated CSPs will have six months from the public notice date to 
file an attestation with the Commission identifying themselves as 
CSPs.\425\ All IP-based CSPs will have 18 months from the public notice 
date to come into compliance with the updated reliability benchmarks 
for physical diversity, operational integrity, and network monitoring, 
or to implement alternative measures. CSPs covered by the 2013 rules 
will continue to be subject to the reliability benchmarks established 
under those rules. CSPs that have previously filed annual 
certifications under the 2013 rules will not be required to file 
additional annual certifications during the transition period. All CSPs 
will file their initial reliability certifications and interoperability 
reports pursuant to the updated rules 18 months from the public notice 
date.\426\

Legal Authority

    We find our approach this Order to strengthen the reliability and 
interoperability of NG911 falls squarely within the legal authority 
that Congress has delegated to the Commission. Congress has enacted 
numerous provisions in the Communications Act of 1934, as amended (the 
Act), and other 911-related statutes ``that, taken together, establish 
an overarching federal interest in ensuring the effectiveness of the 
911 system.'' \427\ The Commission has been granted broad authority, 
for example, to ``promot[e] safety of life and property through the use 
of wire and radio communications,'' \428\ including through use of the 
nation's 911 system.\429\ The Commission's public safety interest is 
among its most important responsibilities, and it informs the 
Commission's exercise of its other statutory authority pursuant to 
Congress's other directives. The D.C. Circuit consistently has affirmed 
the Commission's duty to consider public safety under the 
Communications Act and to impose obligations to protect public safety 
in the public interest.\430\ Beyond this general mandate, section 
251(e)(3) of the Communications Act makes the Commission responsible 
for establishing 911 as the universal emergency telephone number for 
both wireline and wireless telephone service,\431\ demonstrating 
Congress's intent to grant the Commission broad authority for 
``ensuring that 911 service is available throughout the country.'' 
\432\ In a subsequent statute, Congress found that ``for the sake of 
our Nation's homeland security and public safety, a universal emergency 
telephone number (911) that is enhanced with the most modern and state-
of-the-art telecommunications capabilities possible should be available 
to all citizens in all regions of the Nation.'' \433\

the use of wire and radio communications' '' (quoting 47 U.S.C. 151; 
emphasis omitted)); U.S. Cellular Corp. v. FCC, 254 F.3d 78, 85

    Moreover, to the extent that covered 911 service providers are 
common carriers, section 201(b) of the Communications Act requires them 
to adopt ``practices'' that are ``just and reasonable'' and authorizes 
the Commission to ``prescribe such rules and regulations as may be 
necessary in the public interest'' to enforce that requirement.\434\ 
The Commission also may require carriers ``to provide [themselves] with 
adequate facilities for the expeditious and efficient performance of 
[their] service[s]'' when ``reasonably required in the interest of 
public convenience and necessity.'' \435\ The Commission consistently 
has relied on these authorities to regulate the provision of 911 
service, including when it adopted the 2013 reliability rules.\436\ 
Similar provisions empower the Commission to regulate the adequacy of 
the services provided by wireless and interconnected VoIP 
providers.\437\ Based on the record, we find that the 911 reliability 
and interoperability practices and facilities addressed in this Order 
are just and reasonable, serve the public interest, and are required 
for public convenience and necessity.

(VoIP providers).
---------------------------------------------------------------------------

    We also conclude that this Order falls within the Commission's 
broad authority under the Twenty-First Century Communications and Video 
Accessibility Act (CVAA) to regulate the provision of NG911 services 
specifically.\438\ Congress enacted the CVAA to ensure that people with 
disabilities have ``equal access to emergency services . . . as a part 
of the migration to a national [IP]-enabled emergency network[.]'' 
\439\ To further that goal, Congress required the FCC to establish an 
Emergency Access Advisory Committee (EAAC) to recommend ``the most 
effective and efficient technologies and methods'' by which to achieve 
the CVAA's purpose, and Congress provided the Commission ``the 
authority to promulgate regulations to implement the recommendations 
proposed by the [EAAC].'' \440\ Congress also authorized the Commission 
to promulgate ``any other regulations, technical standards, protocols, 
and procedures as are necessary to achieve reliable, interoperable 
communication that ensures access by individuals with disabilities to 
an [IP]-enabled emergency network, where achievable and technically 
feasible.'' \441\ Ensuring the reliability and interoperability of the 
nation's NG911 network therefore is one of the Commission's key 
mandates under the CVAA.

    Our approach comports with the CVAA's mandate because it enhances 
the reliability and interoperability of the nation's NG911 network--the 
IP-enabled emergency network addressed in the CVAA--and is achievable 
and technically feasible. We (1) identify which services and facilities 
are the most critical to modern NG911 networks; (2) establish 
reasonable reliability standards for the providers of these services 
and facilities based on prevailing best practices; (3) require CSPs to 
take reasonable measures to

[[Page 42827]]

enable interoperability between ESInets and NGCS facilities; and (4) 
improve oversight processes. These changes are designed to reduce NG911 
service outages, thereby increasing access to IP-based 911 services for 
people with disabilities, including multimedia capabilities that cannot 
be supported on legacy TDM-based networks.\442\ Indeed, one of EAAC's 
recommendations to the Commission was to ensure an ``[a]ccessible NG9-
1-1 Network'' that could ``support features, functions and capabilities 
. . . to enable individuals with disabilities to make multimedia NG9-1-
1 emergency calls.'' \443\ These advanced 911 features currently are 
the least likely to be supported by existing interoperability measures, 
and users of these services therefore stand to benefit most from the 
911 reliability framework and interoperability measures we adopt 
today.\444\ The EAAC also recommended that the FCC promote 
interoperability by allowing NG911 providers ``to identify the formats 
for their environment[s]'' and to ``convert these formats where their 
environments interface with other environments[.]'' \445\ That is the 
approach we have taken--requiring providers to use reasonable efforts 
to enable interoperability, while affording them flexibility to 
determine the formats in which they will do so.

    As the Commission has recognized consistently in prior rulemakings, 
the Commission's regulatory authority under the CVAA is not limited to 
services that are used exclusively by people with disabilities.\446\ 
Nor does the CVAA ``requir[e] the FCC to ensure that any rules we adopt 
confer zero benefits on consumers outside the disability community[.]'' 
\447\ Rather, we adhere to and advance the CVAA's mandate precisely 
because they promote NG911 reliability equally between people with and 
without disabilities on a platform-neutral basis. Moreover, the EAAC 
concluded that people with disabilities may depend on the same voice 
services as those without disabilities in emergency situations,\448\ or 
they may rely on a caretaker or other persons using such services.\449\ 
We believe we should broadly cover different types of service providers 
to ensure that persons with disabilities have full and equal access to 
emergency services when they are needed.

survey ``overwhelmingly want to be able to call PSAPs using the same 
technologies they use daily and know how to use reliably (just as 
all other citizens can).'' Id. at 19 (``Users need to use familiar 
technologies and methods, such as text/audio/video communication, 
when calling in an emergency and therefore both want and need to be

    \449\ See also Bounce-Back Order, 28 FCC Rcd at 7598, para. 120 
(``In emergency situations, persons with disabilities may need to

---------------------------------------------------------------------------

    We also find that our approach to improve the reliability 
certification process is authorized under section 218 of the Act, which 
allows the Commission to ``inquire into the management of the business 
of all carriers'' and to obtain from them ``full and complete 
information necessary to enable the Commission to perform the duties 
and carry out the objects for which it was created.'' \450\ 
Furthermore, section 4(n) of the Act states that ``[f]or the purpose of 
obtaining maximum effectiveness from the use of radio and wire 
communications in connection with safety of life and property,'' the 
Commission ``shall investigate and study all phases of the problem and 
the best methods of obtaining the cooperation and coordination of these 
systems.'' \451\ The Commission previously has relied on section 4(n) 
in similar contexts, for example, as providing authority to require 
interconnected VoIP providers to report outages and to require 
emergency alerting plans to allow the Commission and other stakeholders 
to review and identify gaps in emergency alerting architecture and to 
take measures to address these shortcomings.\452\ The Commission also 
has authority under the NET 911 Act to ``compile . . . information 
concerning 9-1-1 and enhanced 9-1-1 elements, for the purpose of 
assisting IP-enabled voice service providers in complying with this 
section.'' \453\ Thus, we conclude that, as part of a cooperative 
governance structure for 911, ``the Commission is authorized to gather 
and disseminate information from carriers and other regulatees for the 
purpose of ensuring effective public safety communications,'' including 
by allowing 911 Authorities to access CSP reliability certifications to 
assist with oversight.\454\

    Together, the foregoing statutes confirm the Commission's authority 
and responsibility to establish and maintain a comprehensive and 
effective 911 system.\455\ They give the Commission broad authority to 
ensure that the 911 system is available and accessible and functions 
effectively to process and deliver 911 calls and texts from all people 
in need of aid using any type of service; authorize the Commission to 
adopt the framework and measures herein; and represent the repeated 
endorsement by Congress of the Commission's ability to act in this 
context.\456\ The Commission previously concluded that ``[i]n light of 
these express statutory responsibilities, regulation of additional 
capabilities related to reliable 911 service, both today and in an 
NG911 environment, would be well within Commission's . . . statutory

different technologies.\458\ The Commission sought comment on this 
legal framework in the NG911 Reliability FNPRM,\459\ and no commenter 
argues that the proposed NG911 reliability framework exceeds the 
Commission's statutory authority.

    The Commission historically has shared authority over the 911 
system with state, local, and tribal governments, which exercise their 
oversight through various types of agencies, such as public safety 
agencies and, in some cases, state public utility commissions 
(PUCs).\460\ These agencies play critical roles in ensuring that 911 is 
available when needed, including by ``establishing and designating 
PSAPs or appropriate default answering points, purchasing customer 
premises equipment, retaining and training PSAP personnel, purchasing 
911 network services, and implementing a cost recovery mechanism to 
fund all of the foregoing.'' \461\ Congress recognized the important 
role that states and localities can play in ensuring reliable 911 
service when it directed the Commission to ``encourage and support 
efforts by States'' in this area.\462\ We reaffirm the Commission's 
policy to support efforts by states and localities to deploy 
comprehensive end-to-end emergency communications infrastructure and 
programs, including seamless, ubiquitous, and reliable 911 
service.\463\

---------------------------------------------------------------------------

    We find that our approach strikes an appropriate balance between 
federal guidance and state and local autonomy. As discussed above, we 
do not alter state jurisdiction over 911 or directly affect intrastate 
facilities. We continue to specifically exempt PSAPs and other 
governmental entities from 911 reliability obligations, and they 
empower 911 Authorities by ensuring them access to the reliability 
certifications of CSPs in their states. We also focus on interstate 
facilities within multistate 911 networks that no individual state can 
regulate effectively. Specifically, the new CSP classes we identify 
operate facilities that often extend across state boundaries.\464\ 
Similarly, the ESInet interoperability requirement we adopt applies to 
interstate communications. Consistent with past practice, we intend to 
partner with state, local, and tribal 911 Authorities while respecting 
their unique interest in the delivery of 911 service to their 
communities.
---------------------------------------------------------------------------

    \464\ For example, 911 traffic aggregation facilities, multi-OSP 
LISs and multi-OSP LNGs collect 911 traffic from multiple OSPs that 
may be located in different states and process and transport the 
traffic for ultimate delivery to ESInets POIs in various states 
across the country.
---------------------------------------------------------------------------

    Commenters generally agree with our analysis and characterize our 
approach as an appropriate exercise of federal authority over 911 
systems that also respects the power of state, local, and tribal 911 
Authorities to oversee the 911 network infrastructure within their 
jurisdictions. Colorado's PUC, for example, believes our approach is 
consistent with the Commission's historic approach of ``set[ting] a 
baseline for 911 networks and call delivery and the states add[ing] to 
this through statute, regulation, and service level agreements in order 
to address their own particular needs.'' \465\ NASNA similarly states 
that the Commission's role includes protecting the integrity of NG911 
systems by requiring CSPs to supply all critical elements of NG911 
systems to best practice standards, while 911 Authorities' role is ``to 
define their procurement requirements and their system elements.'' 
\466\ APCO agrees, noting that the new reliability rules are not 
intended to alter states' jurisdiction over 911 or directly affect 
their intrastate facilities.\467\

    \467\ APCO Reply at 11-12. NTCA and the RLEC Parties claim that 
the Commission previously characterized NG911 calls as purely 
``intrastate'' in nature. See NTCA and the RLEC Parties Comments at 
3 (citing NG911 Transition Order, 39 FCC Rcd at 8212-13, para. 165). 
In reality, the Commission was describing its federal/state cost 
allocation rules, which ``treat the costs of transmitting these 
[911] calls as jurisdictionally intrastate'' when the caller and 
call recipient are located in the same jurisdiction. NG911 
Transition Order, 39 FCC Rcd at 8212-13, para. 165 & n. 492 (citing 
47 CFR parts 32, 36, 61, 65, and 69). The Commission has long 
recognized ``that the technologies and commercial relationships that 
form the foundation of the 911 system are transitioning [to NG911] 
and, as a result, becoming increasingly interstate in nature.'' 2014 
911 Reliability NPRM, 29 FCC Rcd at 14208, para. 2. See also APCO 
Reply at 11-12 (``In an NG9-1-1 environment, calls and associated 
data can, and often must, cross state boundaries. The artificial 
division between `interstate' and `intrastate' interoperability has 
no practical basis in the NG9-1-1 ecosystem . . . given the 
inherently interconnected and borderless nature of NG9-1-1 
traffic.'').
---------------------------------------------------------------------------

    Another commenter, while ``recogniz[ing] the need for clear rules 
that promote the reliability of interconnections . . . for reliable 
routing of emergency 911 calls,'' seeks clarification about the scope 
of state and local oversight of 911 reliability.\468\ We clarify that 
the Commission has sole authority to enforce the 911 reliability 
requirements for CSPs codified in part 9 of the Commission's rules. 
Through the Bureau, the Commission determines whether CSP 
certifications are timely and accurate and whether CSPs' network 
implementations comply with the reliability benchmarks or otherwise are 
reasonable alternative measures. We recognize, however, that 911 
Authorities have a shared interest in ensuring the delivery of reliable 
911 service to their constituents. Accordingly, we encourage 911 
Authorities to make the Commission aware of any potential violations of 
the Commission's 911 reliability framework in their jurisdictions, and 
as discussed above, we allow them access to CSPs' reliability 
certifications to aid in that effort.
---------------------------------------------------------------------------

    \468\ NTCA and the RLEC Parties Comments at 3-4.
---------------------------------------------------------------------------

    We further clarify that 911 Authorities may independently require 
NG911 operators in their jurisdictions to provide services or to meet 
performance standards that differ from those described in this 
Order.\469\ In such cases, the Commission will deem a CSP to be 
compliant with the part 9 rules if it truthfully certifies to 
implementing alternative measures that were mandated or approved by its 
911 Authority. It then would fall to the 911 Authority to oversee the 
CSP's performance and to enforce its local requirements via its 
contractual rights or through its laws or regulations. To illustrate, 
Colorado regulates providers

[[Page 42829]]

of ``basic emergency service'' to governing bodies and PSAPs within the 
state, which is defined to include the aggregation and transportation 
of 911 calls.\470\ These providers are overseen in part by the Colorado 
Public Utilities Commission, and they must comply with reliability 
standards that overlap with--but are not identical to--the Commission's 
reliability framework in Sec.  9.19.\471\ The Commission will accept, 
for example, a reliability certification from a Colorado CSP explaining 
that it has implemented alternative measures in lieu of a Commission 
benchmark because the measures were approved by the Colorado Public 
Utilities Commission as part of the provider's required biennial 
improvement plan.\472\ Because our framework accommodates state 
decision-making, there should be no conflict between how the Commission 
and state and local authorities regulate 911 reliability or carry out 
their respective oversight roles and therefore no cause for 
preemption.\473\
---------------------------------------------------------------------------

    \469\ For example, 911 Authorities commonly require five nines 
reliability in their service level agreements with NGCS providers.
    \470\ See 4 Colo. Code Regs. Sec.  723-2-2131; Colo. Rev. Stat. 
Sec.  40-15-201(2); 4 Colo. Code Regs. Sec.  723-2:2130(b).
    \471\ See, e.g., 4 Colo. Code Regs. Sec.  723-2:2143 (requiring 
basic emergency services providers to ``take reasonable measures to 
provide reliable BES including circuit diversity, central-office 
backup power, and diverse network monitoring'' as well as other 
measures).
    \472\ See 4 Colo. Code Regs. Sec.  723-2:2143(b).
    \473\ In the NG911 Transition Order, the Commission similarly 
affirmed the right of 911 Authorities to adopt provisions concerning 
the implementation of NG911 that differ from the Commission's 
framework. See NG911 Transition Order, 39 FCC Rcd at 8140, para 7 
(``[W]e recognize and do not preempt the long-standing authority of 
state and local government over the provision of 911 service. Thus, 
911 Authorities at the state, local, and Tribal level remain free to 
establish alternative provisions within their jurisdictions for the 
implementation of NG911, definition of demarcation points, and 
allocation and recovery of costs.''); id. at 8212-13, para. 165 
(``There can be no preemption where there is no conflict or 
inconsistency between federal and state requirements.'').
---------------------------------------------------------------------------

Benefit and Cost Analysis

    Benefits. The benefits of today's item exceed the costs. This Order 
will lead to improvements in coordination between 911 Authorities and 
CSPs, promote IP reliability best practices and system 
interoperability, enhance state and local government oversight, prevent 
delays in the NG911 transition, and reduce 911 call failures and 
outages. The elimination of annual certification requirements removes 
the costs of unnecessary and excessive filings which would serve little 
value towards realizing these benefits. The Commission has previously 
found that improving 911 reliability produces significant benefits for 
the protection of public safety and is consistent with the Commission's 
statutory charge to promote the safety of life and property through the 
use of wire and radio communications.\474\ We also find that improving 
911 reliability will advance national security objectives, as 911 
outages leave first responders, including police, fire, and EMS 
agencies blind to unfolding threats, such as a terrorist attack.\475\ 
Although sparse in quantitative estimates, the record in this 
proceeding supports our conclusion that the benefits of updated NG911 
reliability framework and interoperability measures include empowering 
state and local governments to manage their NG911 deployments,\476\ 
providing 911 Authorities with visibility and oversight into the entire 
NG911 ecosystem,\477\ and mitigating or preventing large-scale 911 
outages.\478\ Countervailing claims about risk of NG911 transition 
delay have been resolved by our modifications to the proposed 
interoperability benchmark, and replacing the proposed annual 
interoperability certification with a simplified one-time report.\479\ 
While it is difficult to quantify these benefits, we find that the 
benefits of improved NG911 reliability, including the prevention of 911 
outages, would create sizable benefits to the public safety; indeed, 
even if these measures result in the saving of only a single life per 
year, doing so would result in benefits that far exceed the modest 
costs of our approach.\480\ We therefore conclude that the benefits of 
our actions exceed their costs.

note that the value of reducing the mortality risk is approximately 
$14.2 million per life saved, using a methodology developed by the 
U.S. Department of Transportation (DOT) that the Commission has 
relied on in past orders. See U.S. Department of Transportation,

    Costs. Today's item will impose approximately $3 million annually 
and $2.1 million in one-time costs on private businesses.\481\ We note 
that the estimated one-time and annual costs will phase in over the 
next four years after adoption of the Order during the NG911 
transition, as NG911 networks gradually replace legacy TDM 911 
networks.\482\ Most of today's rule changes will impose little or no 
costs. The ESInet and NGCS CSP categories are clarifications or minor 
modifications of the rules adopted in the 2013 911 Reliability 
Order.\483\ The rule updates adding CSP definitions for major IP 
transport facilities operators, IP 911 traffic aggregation facilities 
operators, LIS operators, and transitional gateway operators represent 
minimal changes to keep pace with technology evolution and ensure 
realization of the benefits of the NG911 Transition Order.\484\ Today's 
modifications to substantially reduce the number of entities included 
in the NG911 Reliability FNPRM's proposed covered 911 service classes 
of major IP transport, LIS operators, and transitional gateway 
operators further ensure costs will be minimal. In addition, the IP 
path diversity and IP monitoring benchmarks we adopt today are largely 
codifications of the rule interpretations adopted in the 2015 911 
Reliability Recon. Order.\485\ Furthermore, both of those benchmarks 
and the operational integrity benchmark also codify CSRIC's 
recommendations of NG911 reliability tools that were already available 
or not overly burdensome to implement based on consideration of impacts 
on operations and capital budgets, labor costs, and service downtimes 
for upgrades.\486\ The addition of a one-time

[[Page 42830]]

interoperability report represents a minor update to account for 
rapidly moving technology.\487\ Today's clarifications and 
modifications to the NG911 Reliability FNPRM's proposed IP diversity 
benchmark will further reduce estimated costs. We are also preserving 
flexibility for CSPs to implement alternate reliability practices based 
on engineering decisions in the field, and in a way that best suits 
local needs. The limited measures of this Order will therefore protect 
public safety and national security objectives in a way that is 
tailored to avoid any significant burdens.

    We estimate that the rules adopted in this Order will affect a 
limited number of CSPs. This limited impact reflects the fact that many 
CSPs have already implemented the types of reasonable safeguards 
codified in this Order.\488\ Specifically, we estimate that: (1) the IP 
physical diversity requirements will only require new reliability 
measures from approximately 15 entities total among operators of major 
IP transport facilities, IP 911 traffic aggregation facilities, and 
ESInet facilities; (2) the operational integrity requirement will only 
require new measures for approximately 25 entities; (3) the IP network 
monitoring requirement only require new measures for approximately 25 
entities; (4) the interoperability reporting requirement applicable to 
ESInet facilities and NGCS operators will only require new measures for 
approximately 25 entities; (5) the one-time upfront labor cost 
obligations will apply to approximately 25 entities; and (6) the 
certification requirement will apply to approximately 100 CSP entities.

---------------------------------------------------------------------------

    IP Physical Diversity. We estimate a reduction in the Commission's 
initial estimate of IP diversity costs based on three considerations. 
First, since we have narrowed the major IP transport CSP category, only 
the largest national wireline transport providers' long-haul dedicated 
SIP facilities are likely to be subject to new reliability 
requirements. Second, because our revised IP-based physical diversity 
standards and streamlined certification rules do not require annual 
audits and tagging for each IP path to ``eliminate'' single points of 
failure, we reduce the previously proposed costs in the NG911 
Reliability FNPRM.\489\ Third, information submitted by NGCS or ESInet 
operators under the 2013 rules indicates that most operators already 
implement the level of physical diversity contemplated by the rule. 
According to Commission staff data, nine out of ten ESInet or NGCS 
providers that have filed in 911RCS already submit physical diversity 
reports for their paths to PSAPs, and many already use IP path 
diversity practices substantially similar to the IP 911 reliability 
framework we adopt today.\490\ Accordingly, we estimate approximately 
15 entities will need to obtain new transport facilities under the IP 
physical diversity requirements, reduced from the original 25 entities, 
and at lower costs than originally estimated.\491\
---------------------------------------------------------------------------

    \489\ ESInet operators, major IP transport facilities operators, 
and 911 IP aggregation facilities operators will certify to having 
implemented IP reliability best practices sufficient to ``mitigate'' 
the risks of single points of failure. For example, Motorola's 
description of how it connects its geographically diverse NGCS 
facilities ``to the PSAP via an ESInet'' using multiple 
geographically diverse MPLS circuits with dynamic routing, and using 
``both MPLS and SD-WAN technologies'' to ensure ``efficient delivery 
and enhanced fault tolerance'' satisfies today's IP diversity 
benchmark. Motorola Comments at 7. See also NG911 Reliability FNPRM, 
40 FCC Rcd at 2720, para. 131 (estimating an annual IP diversity 
cost of $2.4 million).

    \491\ We estimate 15 affected entities, including 10 total 
entities in the major IP transport and 911 IP aggregation 
categories, and 5 ESInet operators.
---------------------------------------------------------------------------

    Up-front costs for meeting the IP path-diversity requirement 
involve deploying geographically redundant, load-balancing routers 
capable of automatic re-routing, a cost the Commission estimated as 
approximately $40,000 per CSP.\492\ Assuming 15 entities will need to 
acquire new redundant routers to meet the proposed IP path diversity 
benchmark, the resulting one-time cost would be approximately 
$600,000.\493\ For annual costs, to the extent 15 entities must also 
purchase redundant IP transport to ensure path diversity, we estimate a 
per-entity annual transport cost of $120,000 per CSP, resulting in 
annual diversity costs of $1.8 million.\494\
---------------------------------------------------------------------------

    \492\ See NG911 Reliability FNPRM, 40 FCC Rcd at 2719, para. 
129.
    \493\ $40,000 x 15 entities = $600,000.
    \494\ See NG911 Reliability FNPRM, 40 FCC Rcd at 2719-20, para. 
130 (additional monthly cost of $3,000 IP transport to connect to 
third-party networks and $7,000 dedicated long-haul transport or SIP 
trunking). We estimate the annual IP transport costs = ($3,000 + 
$7,000) per month x 12 months x 15 entities = $1.8 million per year.
---------------------------------------------------------------------------

    Some commenters raise objections to the IP diversity cost estimates 
in the NG911 Reliability FNPRM. The modifications and clarifications we 
adopt today to the IP path diversity benchmark, the IP path diversity 
certification, as well as our reducing the number of major IP transport 
facility CSPs by raising the threshold to OC48 or 2.5 Gbps, excluding 
internet transit and TDM transport, and exempting transport providers' 
own originated 911 traffic as counting towards serving ``two or more'' 
OSPs, have resolved objections that these IP path diversity benchmark 
is too costly.\495\ Specifically, we believe Lumen's estimate of $10 
million in costs for two LATAs is overtaken by the multiple 
substantially reduced regulatory changes from the original proposals 
that we adopt today.\496\ Given our broad reductions in burdens, we 
find Lumen's study does not accurately reflect the costs of our 
approach, despite a lack of clarity in which services Lumen was 
including in its study.\497\ Similarly, we believe that Intrado's 
estimate of $75 million in labor costs, including ``$250,000 per year 
on audit staff for 2 full-time employees'' for all CSPs, is overtaken 
by our substantial reductions in regulatory burdens for certifications 
and interoperability, as well our changes to clarify that the IP path 
diversity benchmark does not require annual audits.\498\

    We also disagree with arguments that today's diversity benchmark 
will significantly increase costs for OSPs.\499\ We disagree with 
Verizon that CSP reliability measures would necessarily force more OSPs 
to perform services in-house.\500\ Even when taking into account any 
increased costs of enhanced reliability measures, there are significant 
cost efficiencies and economies of scale in using shared transport 
facilities.\501\ We further believe that ordinary market pressures will 
also keep OSP costs low, as we do not prevent OSPs from declining to 
hire CSPs and instead obtaining their own cloud-based, VPN, or similar 
public internet transport to send their 911 traffic to in-state NG911 
delivery

[[Page 42831]]

points.\502\ Because OSPs retain the ability to choose how to comply 
with their 911 transmission obligations, either by using a CSP, 
providing their own transport, or identifying non-CSP transport, we 
decline to clarify that reliability obligations are not the cost 
responsibility of OSPs. We see no clear evidence that the updates to 
the 911 reliability framework would necessarily increase the costs of 
non-CSP shared transport options.

    Operational Integrity. The NG911 Reliability FNPRM estimated that 
meeting this benchmark would require investments in servers, UPS 
devices, and collocation space. The Commission estimated the cost of 
servers at approximately $5,000 each, high-end UPS devices at 
approximately $3,000 per unit, and any necessary diverse secondary 
server collocation full-rack space at approximately $700 per 
month.\503\ Assuming that 25 entities would newly undertake these 
reasonable reliability measures, we estimate total one-time costs of 
$200,000 and recurring annual costs of $210,000.\504\ Today's 
clarification that operators of LNGs or other mixed TDM-IP transitional 
facilities may implement either legacy backup power or IP operational 
integrity measures as appropriate (or alternative measures) resolves 
commenter concerns about IP operational integrity costs.\505\

    IP Network Monitoring. The NG911 Reliability FNPRM proposed 
adopting an IP network monitoring capability requirement and sought 
comment on the associated costs. The Commission estimated that most IP 
CSPs already meet this requirement and therefore would incur little to 
no additional compliance burden. We continue to estimate that IP 
network monitoring capability would involve one-time costs of $200,000 
and recurring annual costs of $260,000, as originally proposed.\506\ We 
disagree that the IP monitoring benchmark is costly due to the ``spider 
web-like nature of IP traffic.'' \507\ We are not requiring direct 
monitoring of entire IP traffic paths, only of a CSP's specified 
facilities along those paths--nodes, node links, and routers--as well 
as processing facilities like LIS, NCGS cores, etc.

$260,000 per year).
    \507\ Intrado Comments at 29.
---------------------------------------------------------------------------

    Interoperability. The Commission proposed requiring CSPs to acquire 
interoperability capability and report annually on their efforts to 
become interoperable and sought comment on the associated cost 
estimates. The Commission's analysis assumed approximately 25 such 
entities nationwide and that each would incur both one-time 
implementation costs and ongoing annual costs because of this 
requirement. However, in the Order, we decline to adopt an 
interoperability benchmark, and we reduce the annual reporting 
requirement to a one-time report. We estimate only minimal costs for 
NGCS and ESInet CSPs to submit this report describing their 
interoperability actions and plans. Today's modifications substantially 
reduce the burden of the Commission's proposed interoperability 
benchmark and our change from an annual interoperability certification 
to a one-time report resolve commenter concerns that this rule could be 
more costly.\508\ We nevertheless conservatively estimate one-time 
costs of $200,000 per entity and recurring annual costs of 
approximately $260,000 per entity under this revised rule.
---------------------------------------------------------------------------

    \508\ See Intrado Comments at 28-30.
---------------------------------------------------------------------------

    One-time Labor Costs--Software, Engineering, and Installation. As 
proposed in the NG911 Reliability FNPRM, we estimate that 25 entities 
are likely to spend 160 labor-hours in each of three areas--software, 
engineering, and installation--to meet the new IP benchmarks. No party 
disputed these labor estimates, and in consideration of the other rule 
modifications described in this section, we conclude these estimates 
are accurate. Applying these hour estimates to 25 entities results in a 
total one-time labor cost of $875,568.\509\
---------------------------------------------------------------------------

    \509\ NG911 Reliability FNPRM, 40 FCC Rcd at 2721-22, paras. 
135-36. We estimate 25 entities incur 160 hours of labor in each of 
three categories: $92.44 per hour for software developers, $79.68 
per hour for network engineers, and $36.78 per hour for 
telecommunications equipment installers. This results in a total 
cost of $875,568.
---------------------------------------------------------------------------

    Attestations, Certifications, and Reporting. The attestation and 
streamlined certification requirements adopted here are not unduly 
burdensome. As clarified above, ESInet operators, major IP transport 
facilities operators, and IP 911 traffic aggregation facilities 
operators will certify only to having implemented IP network 
reliability best practices at a level sufficient to mitigate the risks 
associated with single points of failure, rather than to a burdensome 
and labor-intensive annual auditing and tagging exercise. We estimate 
no new incremental costs associated with the initial one-time filings 
applicable to CSPs under the 2013 rules, and only minimal costs for new 
IP CSPs to submit an initial attestation. Furthermore, CSPs will no 
longer file certifications annually, and we estimate only minimal 
annual costs from routine internal compliance inquiries and 
determinations of whether a material change update is needed. 
Accordingly, we apply the unit estimate of $48,156 per CSP per year, 
which represents the costs of the requirement adopted in 2013. We 
further assume that the rules adopted in this Order result in no more 
than 10% incremental cost and multiply it by the projected total 100 
CSPs that will remain upon completion of the NG911 transition, 
resulting in a total average annual cost of approximately 
$481,560.\510\
---------------------------------------------------------------------------

    \510\ $48,156 x 10% x 100 entities = $481,560.
---------------------------------------------------------------------------

    We disagree with claims that the number of certification filers 
could be higher than 100 in a post-NG911 transition environment.\511\ 
Commenters do not substantiate this claim, and the evidence available 
to the Commission indicates that the number of specialized NG911 
providers subject to today's rules remains small and may be 
consolidating further. Entities such as Sinch, Bandwidth, AT&T, Lumen, 
Comtech, and Intrado are increasingly providing multiple NG911 CSP 
functions, including NGCS, ESInet, IP 911 aggregation, major IP 
transport, and shared LIS service.\512\ Similarly, the total number of 
RLECs or small providers that no longer provide covered 911 services 
has increased since the NG911 Reliability FNPRM.\513\ This

[[Page 42832]]

confirms the Commission's expectations that the NG911 transition would 
reduce the regulatory burden on RLECs and small entities.\514\ Finally, 
today's modifications increasing the capacity threshold to OC48 or 2.5 
Gbps for major IP transport facilities, excluding a providers' own 
originated 911 traffic from the ``two or more'' OSP threshold for major 
IP transport, clarifying the exclusion of internet transit and TDM 
transport from the major IP transport CSP category, and specifying that 
only shared LIS and LNG operators are CSPs further undermines the 
argument that the total number of filers will be high.

---------------------------------------------------------------------------

Deregulatory Agenda

    Today, we eliminate an excessive and burdensome annual filing 
requirement which imposes costs on private businesses without 
commensurate benefits. Our new approach to certification requires a 
one-time submission, to be updated only when a CSP undergoes a material 
change in its network or reliability practices. In addition, we end the 
practice of 911 reliability certifications requiring thousands of lines 
of site-based data that describe each PSAP circuit and central office 
hosting facility, and instead require only the common-sense approach of 
state-level reporting. These measures will significantly cut red tape 
and eliminate wasteful regulatory burdens on industry, unleashing 
prosperity and freeing up resources that should be devoted to 
completing the NG911 transition as rapidly as possible.
    Furthermore, the NG911 transition will dramatically decrease the 
burdens on industry of 911 reliability generally. The ongoing migration 
away from legacy 911 networks to NG911 networks means dozens of small 
RLECs will no longer be providing covered 911 services, such as 
operating selective routers or ALI/ANI databases from the local central 
office.\515\ These RLECs will, in many instances, no longer be subject 
to our 911 reliability framework after the migration to NG911. In 
addition, the retirement of legacy TDM 911 circuits and their 
replacement with IP paths will eliminate the need for costly and time-
consuming TDM reliability practices of annual circuit auditing and 
tagging. Today's Order will ensure that these regulatory reductions 
from the NG911 transition will proceed unimpeded.

---------------------------------------------------------------------------

    We also adopt the NG911 Reliability FNPRM proposal to consolidate, 
simplify, and streamline certain rules codified at Part 9, Subpart H of 
our regulations.\516\ Specifically, today we achieve the following 
regulatory reductions: the previous Sec. Sec.  9.19(c)(1) through (3) 
contained 25 subparts and 871 words. Today's amendments reduce 
Sec. Sec.  9.19(c)(1) through (3) to 10 subparts and 486 words. In 
addition, the recordkeeping requirements at previous rule 9.19(d)(3) 
totaled 251 words, and today we reduce it to 107 words at Sec.  
9.20(e). We direct the Bureau to ensure these filing burdens are 
reduced. Collectively, all of these reductions will make our rules 
easier ``for the average person or business to understand,'' reduce 
compliance costs, and ``reduce the risk of costs of non-compliance.''

contain new or substantively modified information collection 
requirements subject to the Paperwork Reduction Act of 1995 (PRA), 
Public Law 104-13. It will be submitted to the Office of Management and 
Budget (OMB) for review under section 3507(d) of the PRA. OMB, the 
general public, and other Federal agencies will be invited to comment 
on the new or modified information collection requirements contained in 
this proceeding. In addition, we note that pursuant to the Small 
Business Paperwork Relief Act of 2002, Public Law 107-198, see 44 
U.S.C. 3506(c)(4), we previously sought specific comment on how the 
Commission might further reduce the information collection burden for 
small business concerns with fewer than 25 employees. In this Second 
Report and Order, we have assessed the effects of these 911 reliability 
framework and interoperability measures will promote the safety of life 
and property, advance national security objectives, and empower state 
and local governments to manage their NG911 deployments, and that these 
benefits outweigh the costs that might be imposed in connection with 
these regulatory requirements that apply to businesses, including those 
with fewer than 25 employees.

Final Regulatory Flexibility Analysis

    As required by the Regulatory Flexibility Act of 1980, as amended 
(RFA), the Federal Communications Commission (Commission) incorporated 
an Initial Regulatory Flexibility Analysis (IRFA) in the Facilitating 
Implementation of Next Generation 911 Services (NG911); Improving 911 
Reliability Further Notice of Proposed Rulemaking (NG911 Reliability 
FNPRM) released in March 2025. The Commission sought written public 
comment on the proposals in the NG911 Reliability FNPRM, including 
comment on the IRFA. No comments were filed addressing the IRFA. This 
Final Regulatory Flexibility Analysis (FRFA) conforms to the RFA and it 
(or summaries of it) will be published in the Federal Register.

A. Need for, and Objectives of, the Rules

    In the Second Report and Order, the Commission adopts rules to 
ensure the resiliency, reliability, and interoperability of NG911 
networks and ecosystems. With the transition to NG911, dedicated 911 
networks are evolving from Time Division Multiplexing (TDM)-based 
architectures to internet Protocol (IP)-based architectures, which will 
provide 911 Authorities with significant new capabilities to respond to 
those in need of emergency assistance and to improve system resilience 
in comparison to legacy 911. However, for NG911 to be fully effective 
and accessible, it is essential that NG911 networks are designed to 
ensure the reliability of critical components and applications and 
interoperability to enable seamless transfer of 911 calls and data. The 
Commission's 2013 reliability rules were primarily designed for legacy 
911 networks and can no longer provide adequate protection for 
increasingly complex NG911 call traffic. In addition, over the last 
decade there has been an increasing number of major, multi-state 911 
service outages in parts of NG911 systems that are outside the scope of 
the Commission's 2013 911 reliability rules. Many of these outages 
likely could have been prevented or mitigated had operators implemented 
reliability and interoperability measures appropriate for modern, IP-
based systems.
    The rules are needed because the ongoing NG911 transition 
represents a significant change in 911 network architecture that will 
substantially alter the class of entities that are providing critical 
911 services, requiring an update to which entities are covered 911 
service providers (CSPs) under the Commission's 911 reliability rules. 
In legacy 911 systems, a single entity such as the local Incumbent 
Local Exchange Carrier (ILEC) or Rural Local Exchange Carrier (RLEC) 
handles most critical 911 functions for the PSAPs in its service areas, 
including routing to PSAPs, maintaining caller location information 
databases, and providing call delivery via trunk lines. In contrast, 
NG911 systems perform these critical functions through a variety of 
service providers, including Emergency Services IP Network (ESInet) 
operators, Next Generation Core Services (NGCS) providers, and various 
third-party platforms providing services to 911 originating service 
providers (OSPs). As the NG911 transition progresses, many smaller 
RLECs who are CSPs under the 2013 rules will stop providing these 
critical 911 functions to state and local government and retire their 
legacy 911 facilities, as larger NG911 service providers start 
performing the functions previously performed by these smaller 
entities.
    In the Second Report and Order, the Commission takes targeted 
actions to ensure the resiliency, reliability, and interoperability of 
the NG911 ecosystem and its components. First, the Second Report and 
Order designates additional categories of CSPs, the entities whose 
operations are essential to NG911 call delivery, and specifies that the 
operation of ESInets and certain NG911 routing and location core 
services (NGCS) are covered 911 services. Second, the Second Report and 
Order updates the benchmark measures CSPs may implement to 
presumptively satisfy their obligation to provide reliable 911

[[Page 42836]]

service with best practices appropriate to IP, and makes clear that 
CSPs can satisfy their reliability obligations if they adopt 
alternative measures requested by their state, local, territorial, or 
tribal 911 Authority. Third, the Second Report and Order requires CSPs 
to report their actions and plans to enable NG911 interoperability. The 
Second Report and Order revises the oversight mechanisms for compliance 
with the 911 reliability rules to minimize burdens on regulated 
entities, including by eliminating annual certifications and requiring 
only one-time certifications with periodic updates following material 
changes, along with an initial one-time filing that it is providing CSP 
services. In addition, the Second Report and Order gives 911 
Authorities access to CSPs' reliability and interoperability reports, 
and codifies the Public Safety and Homeland Security Bureau's 
(Bureau's) process for investigating and remediating non-compliance.
    The updated requirements in the Second Report and Order provide the 
needed transparency to state and local governments and guidance to 
those who operate NG911 infrastructure. The Commission believes the new 
rules will facilitate a more effective and reliable 911 system 
resulting in a national 911 service that is more accessible, reliable, 
and interoperable, increasing the lifesaving benefits for the public.

B. Summary of Significant Issues Raised by Public Comments in Response 
to the IRFA

    Commenters Intrado and Verizon raised issues regarding the impact 
of the rules on small entities, although not in direct response to the 
IRFA. Commenters suggest that the number of certification filers could 
be higher than 100 in a post-NG911 transition environment, and could 
include smaller entities. In the Second Report and Order, the 
Commission found these claims were not substantiated, and that the 
evidence indicates that the number of specialized NG911 providers 
subject to the Second Report and Order remains small and may be 
consolidating further. Similarly, the total number of RLECs or small 
providers who have stopped filing annual 911 reliability certifications 
has increased since the NG911 Reliability FNPRM, confirming the 
Commission's expectations that the NG911 transition would reduce the 
regulatory burden on RLECs and small entities.
    Commenters also claimed that the rules could burden smaller 
providers if they are required to hire third parties for 911 call 
transport or processing that are subject to reliability requirements. 
Because the costs of today's item are minimal, we conclude that any 
costs passed on from CSPs to their OSP customers will be small. In 
addition, the Second Report and Order preserves the ability of smaller 
OSPs to elect not to use CSPs to deliver 911 traffic to ESInets under 
the NG911 framework under our rules.

C. Response to Comments by the Chief Counsel for the Small Business 
Administration Office of Advocacy

    Pursuant to the Small Business Jobs Act of 2010, which amended the 
RFA, the Commission is required to respond to any comments filed by the 
Chief Counsel for the Small Business Administration (SBA) Office of 
Advocacy, and also provide a detailed statement of any change made to 
the proposed rules as a result of those comments. The Chief Counsel did 
not file any comments in response to the proposed rules in this 
proceeding.

D. Description and Estimate of the Number of Small Entities to Which 
the Rules Will Apply

    The RFA directs agencies to provide a description of, and where 
feasible, an estimate of the number of small entities that may be 
affected by the adopted rules. The RFA generally defines the term 
``small entity'' as having the same meaning as the terms ``small 
business,'' ``small organization,'' and ``small governmental 
jurisdiction.'' In addition, the term ``small business'' has the same 
meaning as the term ``small business concern'' under the Small Business 
Act. A ``small business concern'' is one which: (1) is independently 
owned and operated; (2) is not dominant in its field of operation; and 
(3) satisfies any additional criteria established by the SBA. The SBA 
establishes small business size standards that agencies are required to 
use when promulgating regulations relating to small businesses; 
agencies may establish alternative size standards for use in such 
programs, but must consult and obtain approval from SBA before doing 
so.
    Our actions, over time, may affect small entities that are not 
easily categorized at present. We therefore describe three broad groups 
of small entities that could be directly affected by our actions. In 
general, a small business is an independent business having fewer than 
500 employees. These types of small businesses represent 99.9% of all 
businesses in the United States, which translates to 34.75 million 
businesses. Next, ``small organizations'' are not-for-profit 
enterprises that are independently owned and operated and are not 
dominant in their field. While we do not have data regarding the number 
of non-profits that meet that criteria, over 99 percent of nonprofits 
have fewer than 500 employees. Finally, ``small governmental 
jurisdictions'' are defined as cities, counties, towns, townships, 
villages, school districts, or special districts with populations of 
less than fifty thousand. Based on the 2022 U.S. Census of Governments 
data, we estimate that at least 48,724 out of 90,835 local government 
jurisdictions have a population of less than 50,000.
    The rules adopted in the Second Report and Order will apply to 
small entities in the industries identified in the chart below by their 
six-digit North American Industry Classification System (NAICS) codes 
and corresponding SBA size standard. Where available, we also provide 
additional information regarding the number of potentially affected 
entities in the identified industries below.

E. Description of Economic Impact and Projected Reporting, 
Recordkeeping and Other Compliance Requirements for Small Entities

    The RFA directs agencies to describe the economic impact of adopted 
rules on small entities, as well as projected reporting, recordkeeping 
and other compliance requirements, including an estimate of the classes 
of small entities which will be subject to the requirement and the type 
of professional skills necessary for preparation of the report or 
record.
    The Second Report and Order may affect the reporting, 
recordkeeping, and/or other compliance requirements for small and other 
entities that provide 911 services. As explained in Section A of this 
FRFA, the Commission anticipates that the NG911 transition will 
eliminate the burdens on most small entities subject to the 2013 911 
reliability rules, since most small entities designated as CSPs under 
those rules will likely cease providing the services of a CSP. 
Furthermore, eliminating annual certifications and replacing them with 
one-time and periodic certifications will further reduce burdens on all 
entities. Specifically, under the new streamlined certification 
process, CSPs will only be required to submit an initial compliance 
certification in 18 months and to update it in the event of a material 
change to the information covered by the certification. Also, CSPs will 
not be required to separately document reliability practices with 
respect to each individual PSAP served by the CSP, and instead may file 
consolidated certifications for their facilities at the network level 
on a per-state basis. CSPs covered by the updated rules that have not 
previously filed a reliability certification will also file an 
attestation in six months identifying themselves as covered 911 service 
providers. Finally, NGCS and ESInet CSPs will only file a one-time 
interoperability report, instead of the proposed interoperability 
certification to meeting benchmarks. The Commission believes that the 
rules in the Second Report and Order will ultimately not subject these 
small entities to increased burdens, and will not impose compliance 
obligations that require small entities to hire professionals. The 
Commission also anticipates the new requirements in the Second Report 
and Order will generally apply to larger entities.
    In the Second Report and Order, the Commission maintains the 
structure of its 911 reliability framework, which requires all CSPs 
(including those providing NG911 services) to take reasonable measures 
to ensure reliability, and allows the presumptive demonstration of 
``reasonableness'' by meeting certain ``best practice'' benchmarks 
codified in the rules and reported in a certification filing. The 
Commission preserves the flexibility for all CSPs to use ``alternative 
measures'' instead of the benchmarks, and to certify to why those 
alternative measures are reasonable. More specifically, the Commission 
updates the categories of CSPs to include entities performing 
substantial 911 traffic aggregation, transport, and processing 
functions in the NG911 environment. The Commission also updates the 
best

[[Page 42838]]

practice benchmarks applicable to IP and NG911 facilities and adds a 
``reasonable interoperability'' requirement for certain CSPs. Finally, 
the Second Report and Order directs the Bureau to simplify and 
streamline the certification reporting process for CSPs, and to ensure 
911 Authorities have access to the CSP certifications to increase state 
and local government oversight.

F. Discussion of Steps Taken To Minimize the Significant Economic 
Impact on Small Entities, and Significant Alternatives Considered

    The RFA requires an agency to provide ``a description of the steps 
the agency has taken to minimize the significant economic impact on 
small entities . . . including a statement of the factual, policy, and 
legal reasons for selecting the alternative adopted in the final rule 
and why each one of the other significant alternatives to the rule 
considered by the agency which affect the impact on small entities was 
rejected.''
    The Commission believes that the limited measures taken with this 
Second Report and Order will protect public safety and national 
security objectives in a way that is tailored to avoid any significant 
burdens on small entities. Most of the rule changes were carefully 
considered to impose little or no costs on state and local governments 
or industry, including small entities. The ESInet and NGCS CSP 
categories are clarifications or minor modifications of the 2013 rules, 
and the rule updates adding CSP definitions for major IP transport 
facilities operators, 911 IP aggregation facilities operators, LIS 
operators, and LNG operators represent minimal changes to keep pace 
with technology evolution and ensure realization of the benefits of the 
NG911 Transition Order. The IP path diversity and IP monitoring 
benchmarks adopted in the Second Report and Order are largely 
codifications of the rule interpretations adopted in the 2015 911 
Reliability Recon. Order. Furthermore, both of those benchmarks and the 
operational integrity benchmark codify CSRIC's recommendations of NG911 
reliability tools that were already available or not overly burdensome 
to implement based on consideration of impacts on operations and 
capital budgets, labor costs, and service downtimes for upgrades. 
Generally, the Commission believes that the addition of the 
interoperability report requirement represents a minor update to 
account for rapidly moving technology.
    In addition, the Commission takes specific steps to minimize the 
impacts of the rules on small entities. The Second Report and Order 
substantially reduces the number of entities included in the NG911 
Reliability FNPRM's proposed covered 911 service classes of major IP 
transport, IP 911 traffic aggregation, LIS operators, and LNG operators 
to minimize costs on industry, including small business entities. The 
Second Report and Order also narrows the major IP transport CSP 
category to only the largest national wireline transport providers' 
long-haul dedicated SIP facilities. The Commission excludes LIS and LNG 
operators as falling within the regulation unless they provide third-
party services to more than one OSP, and further clarifies that OSPs 
are not subject to the CSP regulations for provisioning their own NG911 
services for their own traffic, or for hiring a CSP.
    The Commission's clarifications and modifications to the NG911 
Reliability FNPRM's proposed IP diversity benchmark and the elimination 
of a specific interoperability benchmark will further reduce estimated 
costs, including on small entities. The Commission believes that the 
revised IP-based physical diversity standard and clarified 
certification rules remove any need for annual audits and tagging to 
``eliminate'' single points of failure for each IP path, so we 
substantially reduce the estimated compliance labor costs for major IP 
transport providers, 911 IP aggregators, and ESInet operators. ESInet 
operators, major IP transport facilities operators, and 911 IP 
aggregation facilities operators will certify only to having 
implemented IP reliability best practices sufficient to ``mitigate'' 
the risks of single points of failure, further reducing potential 
impacts on small entities. The Second Report and Order also eliminates 
the requirement that CSPs file annual compliance certifications and 
adopts a streamlined filing process in which CSPs will submit a one-
time reliability certification subject to updates only in the event of 
material changes. In addition, the Second Report and Order provides for 
an 18-month transition period before CSPs must file initial reliability 
certifications in conformance with the new rules, and during which CSPs 
will not be required to comply with the new reliability benchmarks. 
These steps will minimize the regulatory impacts on all CSPs including 
small entities.
    The Commission preserves flexibility for all CSPs to implement 
alternative reliability practices based on engineering decisions in the 
field, and in a way that best suits local needs--including alternative 
measures agreed upon between a CSP and a 911 Authority. The Commission 
also limits the NGCS CSPs to those that that provide 911 routing and 
caller location services directly by contract to 911 Authorities, 
preserving flexibility for state and local governments in their service 
contracts with NGCS providers, and preserving local decision-making on 
whether state or local governments will enter agreements with NGCS 
providers. Accordingly, state and local governments will not be 
constrained by federal regulations that would automatically impose 
costs on any private entity that does business with state and local 
government, which could impose undue burdens on the smallest local 
government entities such as PSAPs. By preserving flexibility in state 
and local government NG911 deployments, the Commission ensures that 
related cost decisions involving small government entities will be made 
at the state and local level, not by the Commission.
    The Second Report and Order also eliminates annual filing 
requirements, replacing them with a one-time certification that only 
must be updated periodically after a material change, plus a one-time 
filing to confirm CSP status. The Second Report and Order further 
directs the Bureau to streamline the certification form by allowing 
CSPs to report their compliance on a statewide basis, rather than the 
prior process where CSPs had to list each facility separately.

6. Revise and republish Sec.  9.19 to read as follows:


Sec.  9.19  Provision of reliable 911 service.

    (a) Definitions. Terms in this section and Sec.  9.20 have the 
meanings set forth in Sec. Sec.  9.3 and 9.28 and as follows:
    (1) Monitoring aggregation point. A point at which network 
monitoring data for a 911 service area is collected and routed to a 
network operations center (NOC) or other location for monitoring and 
analyzing network status and performance.
    (2) Certification. An attestation by a certifying official, under 
penalty of perjury, that a covered 911 service provider:
    (i) Has satisfied the obligations of paragraph (c) of this section 
and Sec.  9.20(a);
    (ii) Has adequate internal controls to bring material information 
regarding network architecture, operations, and maintenance to the 
certifying official's attention; and
    (iii) Has made the certifying official aware of all material 
information reasonably necessary to complete the certification.
    (3) Certifying official. A corporate officer of a covered 911 
service provider with supervisory and budgetary authority over network 
operations in all relevant service areas.
    (4) Covered 911 service provider. (i) Any entity that provides 
covered 911 services, which are 911, E911, or NG911 services for which 
a failure would impede the real-time routing, delivery, or transfer of 
911 traffic. Covered 911 services include:
    (A) The provision of 911, E911, or NG911 capabilities such as call 
routing, automatic location information (ALI), automatic number 
identification (ANI), or the functional equivalent of those 
capabilities, directly to a public safety answering point (PSAP), 
statewide

[[Page 42840]]

default answering point, or appropriate local emergency authority as 
defined in Sec.  9.3.
    (B) The operation of one or more central offices that directly 
serve a PSAP. For purposes of this section, a central office directly 
serves a PSAP if it hosts a selective router or ALI/ANI database, 
provides equivalent NG911 capabilities, or is the last service-provider 
facility through which a 911 trunk or administrative line passes before 
connecting to a PSAP.
    (C) The provision of Next Generation Core Services (NGCS) 
facilities, including NGCS location facilities or NGCS routing 
facilities, directly by contract or tariffed service to any 911 
Authority, whether via owned and operated facilities or leased or 
contracted facilities.
    (D) The operation of an ESInet or legacy PSAP gateway (LPG).
    (E) The operation of a Location Information Server (LIS) or 
equivalent IP 911 location database that provides service to two or 
more originating service providers (OSPs).
    (F) The operation of a Legacy Network Gateway (LNG), a legacy 
selective router gateway (LSRG), or an emergency services gateway 
(ESGW) used for IP conversion of 911 traffic, that provides service to 
two or more OSPs.
    (G) The operation of a major IP transport facility.
    (H) The operation of an IP 911 traffic aggregation facility.
    (I) The operation of interstate interconnecting ESInet facilities.
    (J) For purposes of the requirement in Sec.  4.9(h) of this chapter 
to notify 911 special facilities about outages that potentially affect 
them, only entities described in paragraphs (a)(4)(i)(A) through (D) of 
this section are ``covered 911 service providers.''
    (ii) The term ``covered 911 service provider'' shall not include 
any entity that:
    (A) Constitutes a PSAP, 911 Authority, or other governmental 
authority to the extent that it provides 911, E911, or NG911 
capabilities; or
    (B) Offers the capability to originate 911 calls where another 
service provider delivers those calls and associated number or location 
information to the appropriate 911 Authority.
    (5) Covered 911 circuits and paths--(i) Legacy covered 911 
circuits. 911 facilities that originate at a selective router and 
terminate in the central office that serves the PSAP(s) to which the 
selective router delivers 911 calls, including all equipment in the 
serving central office necessary for the delivery of 911 calls to the 
PSAP. Legacy covered 911 circuits also include ALI and ANI facilities 
that originate at the ALI or ANI database and terminate in the central 
office that serves the PSAP(s) to which the ALI or ANI databases 
deliver 911 caller information, including all equipment in the serving 
central office necessary for the delivery of such information to the 
PSAP(s). In NG911 transitional architecture, circuits connected to 
LSRGs, ESGWs, or LPGs are also legacy covered 911 circuits.
    (ii) IP covered 911 paths. Paths carrying IP communications that:
    (A) Originate at an NG911 Delivery Point or equivalent ESInet point 
of interconnection and terminate at the last routing facility before 
the NG911 PSAP or the legacy PSAP gateway, including all equipment 
associated with a covered 911 service necessary for the delivery of 911 
traffic to the PSAP, such as any trunks, circuits, or paths to and from 
NGCS facilities and the ESInet transmission network necessary for 
routing and caller location information to the PSAP(s), and any 
intermediate paths in the chains of delivery;
    (B) Transport 911 traffic via major IP transport facilities for 
ultimate delivery at an NG911 Delivery Point or equivalent ESInet point 
of interconnection, including any intermediate paths in the chain of 
delivery; or
    (C) Transport 911 traffic via IP 911 traffic aggregation facilities 
for ultimate delivery at an NG911 Delivery Point or equivalent ESInet 
point of interconnection, including any interconnecting paths between 
ESInets, and including any intermediate paths in the chain of delivery.
    (6) Diversity audit. A periodic analysis of the geographic routing 
of network components to determine whether they are physically diverse. 
Diversity audits may be performed through manual or automated means, or 
through a review of paper or electronic records, as long as they 
reflect whether covered 911 circuits and paths are physically diverse.
    (7) Monitoring links. Facilities that collect and transmit network 
monitoring data to a NOC or other location for monitoring and analyzing 
network status and performance.
    (8) Physically diverse. Circuits or paths are physically diverse if 
they provide more than one physical route between end points with no 
common points where a single failure at that point would cause both 
circuits or paths to fail. Circuits or paths that share a common 
segment such as a fiber-optic cable or circuit board are not physically 
diverse even if they are logically diverse for purposes of transmitting 
data. IP routers, transport nodes, and node links create physical 
diversity if these elements are redundant, geographically distributed, 
load balanced, and capable of automatic failover and rerouting to 
redundant elements sufficient to reasonably mitigate the risks of 
single points of failure.
    (9) Tagging. An inventory management process whereby legacy covered 
911 circuits are labeled in circuit inventory databases to make it less 
likely that circuit rearrangements will compromise diversity. A covered 
911 service provider may use any system it wishes to tag legacy covered 
911 circuits so long as it tracks whether those facilities are 
physically diverse and identifies changes that would compromise such 
diversity.
    (10) Geographically distributed. 911 network architecture is 
geographically distributed if 911 traffic can be delivered through more 
than one covered 911 facility in different geographic locations in 
different physical facilities.
    (11) Load balanced. 911 network architecture is load balanced if 
call volume is dynamically distributed among multiple active databases 
or call processing facilities to accommodate changes in traffic volume.
    (12) Major IP transport facility. Dedicated SIP facilities that 
include voice and text transport meeting or exceeding Optical Carrier 
48 (OC48)/2.5 Gbps in capacity that collect and/or transmit IP 911 
traffic mixed with non-911 traffic, originated from two or more OSPs 
and transported over interstate routes, for ultimate transport and 
delivery to an NG911 Delivery Point or equivalent ESInet point of 
interconnection. Any 911 traffic originated on the facility provider's 
network is not considered for purposes of determining whether a 
provider is serving two or more OSPs.
    (13) IP 911 traffic aggregation facility. Facilities that collect 
and segregate IP 911 traffic from non-911 traffic for two or more OSPs, 
or transport such 911-only traffic for ultimate delivery to an NG911 
Delivery Point or equivalent ESInet point of interconnection. Any 911 
traffic originated on the facility provider's network is not considered 
for purposes of determining whether a provider is serving two or more 
OSPs.
    (14) NGCS location facilities. NG911 IP facilities connected to an 
ESInet that enable the real-time provision of 911 caller location 
information to the PSAPs, including but not limited to the Emergency 
Call Routing Function (ECRF), the Location Validation Function (LVF), 
and successor technologies.

[[Page 42841]]

    (15) NGCS routing facilities. NG911 IP facilities connected to an 
ESInet that enable the real-time routing, delivery, or transfer of 911 
traffic to PSAPs along with callback information and other associated 
data, including but not limited to the Emergency Services Routing Proxy 
(ESRP), the Policy Routing Function (PRF), and successor technologies.
    (16) Interstate interconnecting ESInet facilities. Interstate 
facilities that transport IP 911 traffic from an ESInet for ultimate 
delivery to another ESInet, including facilities designated for 
intermittent, contingent, or backup exchange of IP 911 traffic between 
ESInets.
    (17) Interoperability standards testing. Testing of covered 911 
services and covered 911 circuits and paths to determine whether an 
NG911 interoperability solution conforms to a relevant commonly 
accepted standard.
    (18) Interoperability conformance testing. Testing conducted 
between two or more NG911 covered 911 service providers in different 
states that validate the interoperable exchange of information.
    (19) Interoperability. The technical and operational capability of 
NG911 systems, networks, and services to exchange 911 voice, text, 
data, and multimedia between jurisdictions, PSAPs, and service 
providers, in real time without the need for proprietary interfaces and 
regardless of jurisdiction, equipment, device, software, service 
provider, or other relevant factors.
    (b) Provision of reliable 911 service. All covered 911 service 
providers shall take reasonable measures to provide reliable 911 
service that ensures physical diversity, operational integrity, and 
network monitoring for their covered 911 facilities. Performance of the 
elements of the certification set forth in paragraphs (c)(1) through 
(3) of this section shall be deemed to satisfy the requirements of this 
paragraph (b). If a covered 911 service provider cannot certify that it 
has performed a given element, the Commission may determine that such 
provider nevertheless satisfies the requirements of this paragraph (b) 
based upon a showing that it is taking alternative measures with 
respect to that element that are reasonably sufficient to mitigate the 
risk of failure, or that one or more certification elements are not 
applicable to its network.
    (c) 911 reliability benchmarks--(1) Physical diversity. A covered 
911 service provider shall certify that all IP covered 911 paths and 
legacy covered 911 circuits in its network are physically diverse as 
defined in paragraph (a)(8) of this section.
    (i) For IP covered 911 paths, covered 911 service providers may 
satisfy this physical diversity benchmark by implementing automatic 
rerouting capabilities, load balancing, and geographically-distributed 
routing facilities, transport nodes, and node links sufficient to 
reasonably mitigate the risks of single points of failure. Covered 911 
service providers may use dedicated diverse private facilities such as 
MPLS, cloud-based path redundancy, or VPN services over the public 
internet or equally secure industry protocols as automatically re-
routed paths.
    (ii) For legacy covered 911 circuits, covered 911 service providers 
may satisfy this physical diversity benchmark by conducting yearly 
diversity audits and certifying that all of the legacy covered 911 
circuits in its network are tagged and are physically diverse such that 
no network or facility element constitutes a single point of failure.
    (2) Operational integrity. A covered 911 service provider shall 
certify whether its central offices hosting selective routers, ALI/ANI, 
or functioning as the last central office serving a PSAP, or its LNG, 
LIS, LSRG, ESGW, LPG, or NGCS functional elements covered by paragraph 
(a)(4)(i) of this section in its network achieve operational integrity. 
Transitional elements for TDM-IP conversion, such as the LSRG or LPG, 
may certify to either paragraph (c)(2)(i) or (ii) of this section, in 
the latter case with 24 hours of backup power.
    (i) LNGs, LISs, LSRGs, ESGWs, LPGs, and NGCS facilities covered by 
paragraph (a)(4)(i) of this section achieve operational integrity if 
they have the capability to ensure continuity of services via an 
uninterruptible and continuous power supply and automatic switchover to 
geographically diverse backup facilities sufficient to prevent service 
disruption.
    (ii) For central offices hosting selective routers, ALI/ANI, or 
functioning as the last central office serving a PSAP, covered 911 
service providers satisfy this operational integrity benchmark by 
implementing backup power facilities for covered legacy 911 central 
office facilities for at least 24 hours at full office load if the 
central office directly serves a PSAP, or, for at least 72 hours at 
full office load if the central office hosts a selective router, 
including all equipment design, proper installation, necessary testing, 
and equipment maintenance to ensure the automatic and independent 
function of backup power facilities.
    (3) Network monitoring. A covered 911 service provider shall 
certify whether it uses physically diverse monitoring to detect outages 
and disruptions in its covered facilities.
    (i) Using geographically distributed automatic disruption detection 
and alarm systems to monitor IP covered facilities, including the IP 
routers, transport nodes, and node links used to make covered 911 
circuits and paths physically diverse, constitutes physically diverse 
monitoring.
    (ii) For non-IP covered facilities, maintaining and annually 
auditing physically diverse monitoring aggregation points, monitoring 
links, and NOCs constitutes physically diverse monitoring.
    (d) Compliance date. For covered 911 service providers described at 
paragraphs (a)(4)(i)(E) through (I) of this section, compliance with 
the reliability requirement at paragraph (b) of this section will not 
be required until 18 months from the date of issuance of a Public 
Notice announcing a compliance date for those paragraphs. For all 
covered 911 service providers, compliance with the benchmarks at 
paragraphs (c)(1)(i), (c)(2)(i), and (c)(3)(i) of this section will not 
be required until 18 months from the date of issuance of a Public 
Notice announcing a compliance date for those paragraphs.

7. Add Sec.  9.20 to read as follows:


Sec.  9.20  911 Reliability certifications; interoperability reporting; 
cessation notifications.

    (a) 911 reliability filings--(1) Attestation. (i) Within six months 
of a Public Notice announcing a compliance date for this paragraph 
(a)(1) and filing guidelines, any covered 911 service provider that has 
not previously filed a reliability certification shall submit to the 
Commission an attestation identifying itself as a covered 911 service 
provider. Attestations will not be deemed confidential.
    (ii) Any new covered 911 service provider that begins service for 
the first time after the date in paragraph (a)(1)(i) of this section 
shall submit an attestation when it begins service.
    (2) Certification--(i) Initial certification. Within 18 months of a 
Public Notice announcing a compliance date for this paragraph (a)(2) 
and filing guidelines, a certifying official of each covered 911 
service provider shall submit a certification to the Commission that 
addresses the elements of reliability listed in Sec.  9.19(c)(1) 
through (3).
    (ii) Updates covering material changes. A covered 911 service 
provider must exercise reasonable judgement in determining whether 
there is a material

[[Page 42842]]

change to its ownership structure, networks, facilities, operations, or 
reliability practices that renders its previous certification no longer 
accurate and file an updated certification within 90 days of discovery 
of such a material change, unless:
    (A) The cause of the change is remedied within the applicable 
update period;
    (B) The change reflects incremental conformance with the 
reliability elements in Sec.  9.19(c)(1) through (3), rather than 
reliance on alternative measures, for less than 50 percent of its 
covered 911 services, circuits, and paths; or
    (C) The change to a covered 911 service provider's ownership 
structure is pro forma in nature.
    (iii) Non-conforming facilities and services. If a covered 911 
service provider does not conform with the elements of reliability 
listed in Sec.  9.19(c)(1) through (3), it must include in its 
certification with respect to each of its non-conforming covered 911 
circuits or paths and covered 911 services whether:
    (A) The covered 911 service provider has taken alternative measures 
to mitigate the risks of lack of physical diversity, operational 
integrity, or network monitoring; or
    (B) The physical diversity, operational integrity, or network 
monitoring benchmark is not applicable to the covered 911 service 
provider.
    (iv) Covered 911 service providers are required to answer 
additional questions about covered 911 circuits and paths and covered 
911 services as directed by the Public Safety and Homeland Security 
Bureau.
    (b) 911 interoperability reports. (1) Each NGCS and ESInet covered 
911 service provider defined in Sec.  9.19(a)(4)(i)(C) or (D) shall 
submit a one-time report to the Commission describing its specific 
actions and plans to enable NG911 interoperability consistent with 
Sec.  9.19(a)(19) within 18 months of a Public Notice announcing a 
compliance date for this paragraph and filing guidelines.
    (2) NGCS and ESInet covered 911 service providers defined in Sec.  
9.19(a)(4)(i)(C) or (D) are required to answer additional questions 
about covered 911 circuits and paths and covered 911 services as 
directed by the Public Safety and Homeland Security Bureau.
    (c) Confidential treatment of certifications and reports. (1) The 
fact of filing or not filing 911 reliability certifications and 911 
interoperability reports shall not be treated as confidential.
    (2) Information submitted with such certifications and reports 
shall be presumed confidential to the extent that it consists of non-
public descriptions of networks or facilities, compliance plans, or 
additional information requested by the Bureau with respect to a 
certification.
    (d) 911 Authority access to certifications and reports. (1) 
Following the compliance date for initial certifications and reports, a 
statewide, territorial, or tribal 911 Authority may request that 
covered 911 service providers produce copies of their 911 reliability 
certifications and interoperability reports to the extent they pertain 
to covered 911 services or covered 911 circuits and paths located 
within or providing services to the 911 Authority's jurisdiction.
    (2) Covered 911 service providers must provide the requested 
certifications or reports within 14 days of a request. Covered 911 
service providers may omit or redact information relating to portions 
of their networks or facilities that are not located within and do not 
provide service to the requesting 911 Authority's jurisdiction. Covered 
911 service providers may condition the granting of such requests on 
the 911 Authority's execution of a confidentiality agreement under 
terms not more restrictive than those set forth in Sec.  4.2 of this 
chapter and in related guidance, instructions, and forms published by 
the Commission.
    (3) To the extent the Public Safety and Homeland Security Bureau 
provides statewide, territorial, or tribal 911 Authorities with, or 
grants them access to, 911 reliability certifications and 
interoperability reports, it shall do so in accordance with relevant 
confidentiality terms and conditions pursuant to which it provides 
access to NORS data under Sec.  4.2 of this chapter and related 
guidance, instructions, and forms published by the Commission.
    (e) Record retention. A covered 911 service provider shall retain 
records supporting its responses in 911 reliability certifications and 
interoperability reports for two years from the date of filing, and 
shall make such records available to the Commission upon request. To 
the extent that a covered 911 service provider maintains records in 
electronic format, records supporting such a certification or report 
shall be maintained and supplied in an electronic format. Such records 
shall include, at a minimum, any audit records, internal reports 
concerning reliability and interoperability compliance, records of 
action to achieve reliability and interoperability compliance, and 
testing and maintenance of reliability and interoperability measures 
and technology.
    (f) Covered service cessation notices. Covered 911 service 
providers that cease covered operations under Sec.  9.19 must notify 
the Commission by filing a notification under penalty of perjury no 
later than 60 days after the cessation of service.
    (g) Remedial action orders and procedures. When acting pursuant to 
authority delegated under Sec.  0.392(j) of this chapter to order 
remedial actions, the Chief of the Public Safety and Homeland Security 
Bureau (Bureau Chief) will carry out restricted non-public proceedings 
with parties regulated under this subpart as follows:
    (1) Notice. If certifications or other information available to the 
Commission indicate that a covered 911 service provider may not be 
taking reasonable measures to provide reliable 911 service, the Bureau 
Chief may issue and electronically serve upon the covered 911 service 
provider a notice that describes any apparent deficiencies and proposes 
remedial actions. The notice may include requests for relevant 
documents and information.
    (2) Response. A covered 911 service provider may submit a written 
response to a notice within 30 days of service of such notice and shall 
provide any requested documents and information by such date. Service 
shall be made as directed by the Bureau.
    (3) Order. At any time after the 30th day following service of a 
notice, the Bureau Chief may issue and serve upon the covered 911 
service provider an order setting forth its findings as to such 
deficiencies and specifying the actions that the covered 911 service 
provider is required to take to mitigate the deficiencies. The order 
may specify deadlines by which the covered 911 service provider must 
complete the required actions and may identify information that the 
provider must submit to demonstrate its compliance with the order.

[[Page 42843]]

    (4) Notice to 911 Authorities. The covered 911 service provider 
shall deliver a copy of the order promptly to the 911 Authority for 
each jurisdiction in which its actions have been found deficient or in 
which it has been directed to take remediating actions.
    (h) Compliance date. This section may contain information 
collection and recordkeeping requirements that require review by the 
Office of Management and Budget. Compliance with new information 
collection and recordkeeping requirements will not be required until 
this paragraph (h) is removed or contains a compliance date.
