ATIS-0100039 Network Reliability Steering Committee 2010-2012 Operational Report 07/01/2013 The Alliance for Telecommunications Industry Solutions’ (ATIS) Network Reliability Steering Committee (NRSC) addresses network reliability improvement opportunities of service providers and vendors, in a noncompetitive environment, and allows participants to develop standards, technical requirements, technical reports, bulletins, Best Practices, and reports on the health of the nation’s communications networks. The NRSC also coordinates industry improvements in network reliability through outage analysis. The mission statement of the NRSC is to improve network reliability by providing timely consensus-based technical and operational expert guidance to all segments of the public communications industry. The NRSC is deeply committed to intra-industry collaboration, which is essential in ensuring that the industry’s expertise is available to monitor and address critical trends in the reliability of our nation’s public communications networks. The NRSC addresses these critical trends by; 1) Identifying potential network reliability issues through an opportunity evaluation process; 2) Establishing teams to work specific reliability issues; 3) Conducting special studies to develop industry recommendations and/or Best Practices; 4) Providing industry feedback to the Federal Communications Commission Public Safety and Homeland Security Bureau (FCC PSHSB) on network reliability and on the FCC’s Network Outage Reporting System (NORS) and Disaster Information Reporting System (DIRS); and 5) Serving as a public educational resource on network outage trends and the industry’s ongoing efforts to resolve network reliability concerns. This Operational Report covers the period of 2010 through 2012.

2004 NRSC Annual Report 10/01/2005 This Annual Report reviews the health of the wireline telecommunications networks for the year 2004, as determined by statistical analysis of major outages reported by service providers to the FCC. This analysis is intended to advise the various stakeholders of the telecommunications industry on the network reliability results that were observed during the previous year from a very special perspective. While any individual company can analyze their own major outage events, only the NRSC brings the industry together in a non-competitive setting to objectively analyze the macro outage data for the United States wireline telecommunications industry, and when necessary, cooperatively bring to bear the industry’s resources when problems are identified. The statistical analysis techniques employed by the NRSC are objective methodologies that were developed and approved by the ANSI accredited ATIS Standards Group on Network Reliability and Performance. These techniques provide many benefits.

The past year was an extraordinary one, marked by dramatic events that have highlighted the criticality of the nation’s communications infrastructure. Telecommunications reliability was not only challenged by natural disasters, but also by the damage as a result of the September 11th terrorist attack. The industry’s cooperation and commitment to service and reliability enabled it to meet these challenges.
