§ 12.1   Purpose.

   top

   The  rules in this part include requirements that will help ensure the
   resiliency,  redundancy  and  reliability  of  communications systems,
   particularly 911 and E911 networks and/or systems.

§ 12.2   Backup power.

   top

   Local  exchange  carriers (LECs), including incumbent LECS (ILECs) and
   competitive  LECs  (CLECs), and commercial mobile radio service (CMRS)
   providers must have an emergency backup power source for all assets that are
   normally powered from local AC commercial power, including those inside
   central offices, cell sites, remote switches and digital loop carrier system
   remote terminals. LECs and CMRS providers should maintain emergency back-up
   power for a minimum of 24 hours for assets inside central offices and eight
   hours for cell sites, remote switches and digital loop carrier system remote
   terminals that are normally powered from local AC commercial power. LECs
   that meet the definition of a Class B company as set forth in §32.11(b)(2)
   of the Commission's rules and non-nationwide CMRS providers with no more
   than 500,000 subscribers are exempt from this rule.

   Effective Date Note:   At  72 FR 37673 , July 11, 2007, §12.2 was added,

   top

   The following entities must analyze their 911 and E911 networks and/or
   systems and provide a detailed report to the Commission on the redundancy,
   resiliency, and reliability of those networks and/or systems: Local exchange
   carriers (LECs), including incumbent LECs (ILECS) and competitive LECs
   (CLECs); commercial mobile radio service providers required to comply with
   the  wireless  911  rules  set  forth  in  §20.18 of this chapter; and
   interconnected Voice over Internet Protocol (VoIP) service providers. LECs
   that meet the definition of a Class B company set forth in §32.11(b)(2) of
   this chapter, non-nationwide commercial mobile radio service providers with
   no more than 500,000 subscribers at the end of 2001, and interconnected VoIP
   service  providers  with  annual  revenues below the revenue threshold
   established pursuant to §32.11 of this chapter are exempt from this rule.

   (a) The Public Safety and Homeland Security Bureau (PSHSB) has the delegated
   authority to implement and activate a process through which these reports
   will be submitted, including the authority to establish the specific data
   that  will  be  required. Where relevant, these reports should include
   descriptions of the steps the service providers intend to take to ensure
   diversity and dependability in their 911 and E911 networks and/or systems,
   including any plans they have to migrate those networks and/or systems to a
   next generation Internet Protocol-based E911 platform.

   (b) These reports are due 120 days from the date that the Commission or its
   staff announces activation of the 911 network and system reporting process.

   (c) Reports filed under this Part will be presumed to be confidential. These
   reports will be shared with The National Emergency Number Association, The
   Association of Public Safety Communications Officials, and The National
   Association of State 9–1–1 Administrators only pursuant to a protective
   order. PSHSB has the delegated authority to issue such protective orders.
   All other access to these reports must be sought pursuant to procedures set
   forth  in 47 CFR 0.461. Notice of any requests for inspection of these
   reports will be provided to the filers of the reports pursuant to 47 CFR
   0.461(d)(3).

   Effective Date Note:   At  72 FR 37673 , July 11, 2007, §12.3 was added. This
   section contains information collection and recordkeeping requirements and
   will not become effective until approval has been given by the Office of
   Management and Budget.
