Network Change:
Network Access Services
Description of Type of Changes Planned: /
In order to standardize this service offering across the SBC13-State footprint, SBC Midwest Region 5 State will outsource its CNAM Access service to the SNET Diversified Group (SNET DG). This change will become effective March 28, 2006 with a CNARG (Calling Name Access Routing Guide) update. Customers should be prepared to make all relevant translation changes necessary to re-direct their CNAM traffic (Native and Ported) to SNET DG, effective, March 28, 2006. Customers will notice billing/invoice format changes as a part of this transition. Companies that administer CNAM data will continue to use the same administrative system and the same methods used today (discussed below).
Description of Reasonably Foreseeable Impact of the Planned Changes: /
Data migration will be supported by updates to the CNARG, effective March 28, 2006 and by updates to NPAC effective 03/28/2006. Companies that store ported numbers in these databases will need to update the Number Portability Administration Center (NPAC) routing information for their CNAM records. Companies that need to make changes to their NPAC information must also coordinate the changes with Arkansas, Kansas, Missouri, Oklahoma, Texas, California, Nevada, Connecticut as appropriate, so that the substitution tables in the Local Service Management System (LSMS) are also updated. Account Managers for these companies will begin making contact for this coordination in January 2006. Participation in this coordination effort is important so that there is no loss of query access to ported number information.
Billed Number Group (BNG) Coordinators and Network Administrators:
Please make note of the following changes that will occur in the CNARG:
·  New alias to query CNAM data for SBC Midwest Region 5 State is: 243-250-005
·  The point codes that will return responses to queries against the CNAM IDs for this data, are: 243-002-010 and 243-002-011.
