3. CO/NXX Subcommittee Permanent p-ANI Guidelines
INC received the NANC Recommendation for Permanent pANI Administration and opened Issue 534 for development of permanent pANI Administration Guidelines
INC CO/NXX Subcommittee and ESIF-H Subcommittee (which includes NENA) have met on a continuing basis and have developed a draft of the Guidelines
INC believes it is on schedule to meet the goal of completing the Guidelines by March 9, 2007
INC and ESIF will request a meeting with the p-ANI IMG or contact the NANC if policy questions arise

4. CO/NXX Subcommittee Issue 322: Removal of Switch from Part 1
INC closed this Issue in 2002 to remove switch CLLI information from the NXX Code forms because:
The switching information is not needed since the purpose of the forms is to provide NANPA with information required to make assignments of NXX codes
The Months-to-Exhaust and Utilization level criteria for an NXX code assignment are rate center based
SPs may port numbers between switches within a rate center to balance resources, thus the switching information may be moot
Requiring switching information on the forms causes the industry to maintain synchronous data in more than one database that leads to inefficiencies, database discrepancies, and added costs for all involved

5. CO/NXX Subcommittee Issue 322: Removal of Switch from Part 1 (cont)
Of added significance, there are also national security concerns with switching information being on public websites, as identified in FCC NRIC VI Best Practices and NIIF NRRIC Issue 0237 regarding the NANPA website
The FCC rejected the associated NANPA Change Order as some state PUCs want the information from NANPA (including the NANPA website)
ATIS INC and NRRIC made a follow-up ex parte presentation to FCC staff in June 2005 (see presentation at
Following FCC staff advice, INC discussed with some state PUC staff the information available from other sources, with some at no cost.
While a significant number of state PUCs agreed with the removal of the switching information from the forms, a few still have not and INC does not understand why
Telcordia has offered a LERG Online demonstration to the NARUC State Coordinating Group and INC hopes this will resolve the state PUC concerns with the implementation of Issue 322

6. LNPA Subcommittee Issue 506: Update the TBPAG Appendix 2 per LNPA WG Request Regarding Unusable Blocks
Upon the request of the NANC LNPA WG, INC made changes to Thousands-Block Pooling Administration Guidelines (TBPAG) and Appendix 2 Thousands-Block Donation Form
The change was requested due to carriers donating contaminated blocks prior to completing IntraService Provider Ports (ISPs) on unavailable numbers
The changes require additional details be provided regarding contaminated block donations and direct the PA to reject donations of such blocks if the completion of ISPs is not confirmed
The new form requires the SP to certify the information provided is accurate
This issue has generated PA Change Order #51 and the proposed changes will not go into effect until after the PA Change Order is approved by the FCC

7. LNPA Subcommittee Issue 407: Treatment of Dedicated Codes for Single Customers in a Pooling Environment
In response to a NANC Action Item, INC revisited Issue 407
This issue allows a Service Provider to request a code for a dedicated customer directly from NANPA in a pooling area significantly increasing the efficiency of obtaining resources for large enterprise customers
In the past three years, an annual average of 135 dedicated code requests have been processed in pooling areas
Combined with the required safety valve process, any additional delay jeopardizes the retention of the customer
The type of customer able to utilize a full NXX generates significant revenues
This change would allow for dedicated codes to be assigned to large enterprise customers up to 14 calendar days sooner
The adoption of this change would positively impact the large enterprise customer while not negatively impacting the porting process or number resource optimization

8. LNPA Subcommittee Issue 515: Contamination Level of Abandoned Thousands-Blocks Issue 535: Block Contamination Information for Block Returns
Upon review of these two issues, INC determined that the PA needs NPAC ad hoc reports to prevent placing blocks with more than 10% contamination into the pool
A letter was submitted to the NAPM LLC to seek approval of the PA receiving NPAC ad hoc reports
