CharterCharter

The purpose of the Packet Switching Best Practices Subcommittee is to provide recommendations for the FCC and to the telecommunications industry that, when implemented, will assure optimal reliability of public telecommunications networks. The duties of the Subcommittee will be to gather the data and information necessary to prepare studies, reports, and recommendations for assuring optimal packet switched network reliability within the parameters set forth in the NRIC V Charter. The Subcommittee will also monitor future developments to ensure that network reliability is not at risk.

Building on the work of NRIC IV, as appropriate, the Subcommittee will continue to develop best practices recommendations and refine or modify, as appropriate, best practices recommendations. The Subcommittee will evaluate and report on the extent to which telecommunications common carriers and equipment suppliers are using best practices recommendations and applicable ANSI Committee T-1 standards, and identify ways to increase the use of best practices and relevant Committee T-1 standards by telecommunications service providers and equipment suppliers.

The Subcommittee’s scope includes packet switching-based wireless network services.

Survey OverviewSurvey Overview

• Subcommittee Charter shaped the Survey Objectives:

a) evaluate and report on the extent to which telecommunications common carriers and equipment suppliers are using Best Practices recommendations, and

b) identify ways to increase the use of Best Practices

• In addition to Implementation, other factors were measured:

– Cost of Implementing the Best Practice

– Effectiveness of the Best Practice

– Risk of Not Implementing the Best Practice

• Detailed Analysis Report for each Best Practice

Best PracticesBest Practices

• Words from the First Council

“ Not every recommendation will be appropriate for every company in every circumstance, but taken as a whole, the Council expects that these findings and recommendations will sustain and continuously improve network reliability. ”

• Previous Councils identified Best Practices, already in use by individual companies, for consideration by the rest of the industry.

• Best Practices are . . . not requirements or standards

Additional Survey Response AnalysesAdditional Survey Response Analyses

• Survey Response Analysis conducted on “Keywords”

- Essential Services, Security, Power, Fire, Procedures, etc.

• Understand the “why’s” for lowest scoring Best Practices (e.g., least implemented)

• Look for insights from relationships among Implementation, Effectiveness, Cost, and Risk

• Glean insights into how to promote better implementation of Best Practices

““Monitor Developments”Monitor Developments”• Developments

– September 11, 2001 Terrorist Attacks New Best Practices being considered – capture learning Include “Emergency Preparedness” and “Disaster Recovery” for

association as keywords Provide tutorials to various government entities on Best Practices
