4. 3/15/2005NOWG March 2005 NANC Report4 PA Change Order Recommendation Change Order # 38 dated January 14, 2005 This change order contains several PAS users suggestions to enhance the productivity of PAS. The seven (7) proposed enhancements to PAS contain ideas suggested by PAS users. They range from the user being able to re-set their password (without having the PA do it) to a disclaimer that a preferred block might not be available by the time the application is processed to adding Part 3 and Part 4 reminder notifications to PAS. This is a change in the scope of programming for PAS and as such the NOWG recommends that this change order be approved so that the industry will benefit from being able to enhance the usability of PAS for the SP.

5. 3/15/2005NOWG March 2005 NANC Report5 PA Change Order Recommendation Change Order # 39 dated February 18, 2005 This change order proposes that PAS be modified to provide two Part 4 reports, similar to the Part 4 reports that carriers can presently obtain from the NAS. Currently there is no Thousands-Block Part 4 Report in PAS for either assignments needing Part 4s or those Part 4s that have already been submitted. The PA submitted Change Order #25 (Thousands-Block Part 4 Report) previously to establish some kind of Part 4 report in PAS. The PA also submitted Change Order #34 (SP Enhancement – Modify Part 1A Report) after a service provider sent in a suggestion to add a column to the Part 1A report that would have the Part 3 effective date in it. Change order 34 was an attempt to establish some sort of Part 4 report. After reviewing both change orders, the NOWG did not recommend approval for either #25 or #34, but did recommend that the PA submit another change order containing the NOWG recommendations from #25 & #34. The PA has taken the NOWG recommendations on both previous change orders and has incorporated those recommendations into the current change order (#39). After reviewing this change order, the NOWG recommends that this change order be approved.

7. 3/15/2005NOWG March 2005 NANC Report7 NeuStar Board of Director Additions On January 28, 2005, NeuStar notified the Wireline Competition Bureau, Federal Communications Commission via Letter, regarding the addition of two (2) new members to the NeuStar Board of Directors. Chairman Atkinson directed the NOWG to consider this request on behalf of the NANC the same day. The NOWG has been tasked with providing feedback to the NANC of any perceived issues regarding the contents of this notification. The NOWG considered this request and asked NeuStar questions as to the additional BOD members qualifications for Neutrality and Independence. NeuStar responded that the new Board members were consistent with the NeuStar Safe Harbor Order, and that they are not employed by any of the entities appearing on the FCCs list of Telecommunications services, they also reiterated that the Board members have signed the appropriate NeuStar neutrality compliance certifications, certifying their adherence to the NeuStar Code of Conduct. The majority of the NOWG did not identify any perceived issues.

The NARUC and the INC sent notices via their distribution channels. All parties sent reminder e-mails. The response due date was March 4th, and because of continued interest in participation and the fact survey's are still being submitted, the cut-off date has been extended until March 31st. We are in the process of gathering the results, creating a matrix of respondents and tallying the ratings and comments.
