3INC Report to the NANC - September 25, 2003

VoIP Workshop• The INC Voice Over Internet Protocol (VoIP)

Workshop identified and discussed many different aspects of Public Switched Telephone Network (PSTN) numbering assumptions and assignment practices with respect to VoIP technology.

• It became evident that the widely disparate opinions would best be captured on a simple chart, with no conclusions being drawn.

• INC determined that there is no need to change INC guidelines until such time as regulatory decisions may provide direction, or if INC is requested by some entity such as the NANC to recommend such changes.

LNPA Workshop• In responding to the NANC action item, the INC has met with

the LNPA Working Group and NANPA, taking into consideration the concerns of state regulators.

• INC then identified three situations that may warrant additional Location Routing Numbers (LRNs):– When there are multiple tandems owned by different service

providers (SPs) in a single LATA, the requesting SP may obtain a new NXX in order to establish an LRN for each subtending point of interconnection (POI).

– Regulatory waivers granted to ILECs to carry local calls across a LATA boundary may exist. In such instances, SPs may be justified in establishing an additional LRN to properly route calls.

– A unique LRN is required for each NPAC region within a single LATA when a single switch serves multiple NPAC regions.

• The PA receives industry direction from the “Thousands-Block Pooling Administration Guidelines,” while SPs receive guidance for selecting LRNs from the “Location Routing Number Assignment Practices.”

• The issue is now in initial closure.

5INC Report to the NANC - September 25, 2003

CO/NXX Workshop INC has two issues on wireless grandfathered

codes and poses these questions to the NANC: First Issue

In Fall 2002, NANC and INC agreed that blocks donated to a pool from wireless grandfathered NXXs cannot be assigned to service providers (SPs) until regulatory authorities direct how to handle these unique numbering resources.

The United States Telecom Association (USTA) filed a petition with the FCC on September 8, 2003 urging the FCC to clarify and exempt from porting grandfathered NXX codes.

Should the telephone numbers (TNs) within these codes be exempt from porting?

6INC Report to the NANC - September 25, 2003

CO/NXX Workshop - continued Second Issue:

The California Commission allows wireless SPs who agree to make no further TN assignments from grandfathered NXXs to exempt the NXXs from the utilization calculation when the wireless SP applies for growth resources.

A proposal has come to INC to modify INC guidelines stating that wireless SPs that intend to donate blocks from these codes (when they become 10% or less contaminated) should be permitted to exclude this inventory now for purposes of calculating months-to-exhaust and utilization.

Does the California decision override the FCC rule on criteria for obtaining additional resources?

INC, before proceeding with work on these two issues, seeks feedback from the NANC today.
