NANC Number Conservation Ad Hoc Charge (per 2/21 NANC)

1. NANC Number Conservation Ad Hoc Charge (per 2/21 NANC) • Should an IMG be commissioned? • If yes, Scope of assignment • Time & Budget

2. Ad Hoc Call Participants-March 12, 2001 • Ed Gould, Penn Pfautz, Mark Lancaster - AT&T • Phil McClelland - Office of Consumer Advocate Pennsylvania • Barbara Meisenheimer - Missouri Office of Public Counsel • Dan Kearney - Michigan Public Service Commission • Trent Boaldin - OPASTCO • Jim Goldstein - Nextel • Brenda Stevens - CRTCT • Brian Baldwin - Telcordia • Greg Pattenaude - NY PSC • Beth O'Donnell - NCTA • Peter Guggina, Karen Mulberry, Steve Engelman - WorldCom • Keith McIntosh -Canadian Wireless Telecommunications Association • Beth Kistner ALTS • Norm Epstein - Verizon • Bill Adair - SBC • Cathie Capita - Voicestream • Wendy Potts - Bell Canada • Eleanor Willis-Camara - Winstar • Switzon Wigfall - North Carolina Utilities Commission • Larry Krevor - Nextel • Natalie Billingsley - NASUCA • Nancy Brockway New Hampshire PUC • Rose Travers - USTA • Hoke Knox - Sprint • Dawn Lawrence - XO Communications

3. Suggested Goal of Work • Determine Lifetime of NANP considering use of optimization techniques. Determine costs of implementation of prioritized techniques. • Selection of best Number Plan Expansion technique. Determine costs of implementation. • Comparison of Above to assess best direction.

4. Ad Hoc Meeting ResultsMarch 12, 2001 • Group considered the charge • Agreed to the need for additional NANP optimization activities and Number Plan expansion studies • Many favored a new IMG to better tie together the final goal, many didn’t have a preference versus assignment of Number Optimization work to NRO.

5. Proposal • Charter New IMG with two major activities: • Evaluate Number Optimization techniques • Use List from February NANC meeting • Evaluate NANP expansion • Compare and Develop Direction • Focus first on analysis of optimization options • Follow with review of the INC NANP expansion report adding additional information, such as cost analysis • Maybe some time period with overlap of work

6. Proposed Approach for Optimization • Develop model(s) that will address what drives Number Plan exhaust • Develop Baseline Number Plan Exhaust Date • Identify impacts of Additional beneficial methods • Determine preferred alternatives • Evaluate costs

7. Optimization Data Analysis • Develop a set of analyses to be performed on NRUF data to • Understand utilization/consumption at each resource level (NPAs, CO Codes, TNs) • Estimate the effect of each conservation alternative (start with February NANC list)

8. Number Optimization Timeline and Costs • Two months to develop initial analyses • Two month iteration with data • Two months for final analysis • Need NANPA to perform analysis on disaggregated data. Could be NANPA costs for data analysis.

9. NANP Expansion Evaluation • Review INC assumptions, conclusions • Consider Network and End User costs • Assess Expansion in relation to Number Optimization options • Begin work after INC report is available • No identifiable costs but could have if Consultants required for End User cost determination. • Timeline not identified but likely 6 months after INC completion
