Error Reduction for DPC entries in new ported and pooled records

Origination Date :01/08/2008



Business Need:

Qwest has found that some Service Providers do not populate the Vertical Services (CNAM/LIDB/CLASS/ISVM) Destination Point Code entries correctly on ported and pooled records.  This creates a three-part problem:

1.) a large volume of Message Transfer Part (MTP) routing errors in participating networks,

2.) the need for trouble reports and the necessary manual work to follow up on the trouble reports, and

3.) the need for Modify broadcasts to get the ported and pooled records corrected.

Besides the impact on Service Providers that have to deal with the routing data errors, consumers are impacted when their SS7-based services do not operate correctly.  Because the current Service Provider’s Final GTT values override the vertical service point codes used on the NPAC’s ported and pooled records, for numbers served within its network, the current Service Provider may not be aware of the problem unless contacted by another provider.

This change order improves the accuracy of all DPC values on new ported and pooled records.

Final Resolution:

Backward Compatible:  YES

The proposed change modifies the NPAC, by maintaining a table of “valid” Vertical Service Destination Point Codes for each SPID (hereafter called “VST” or Vertical Service Table).  The VST allows the NPAC to implement a business rule to detect a port request with one or more incorrect Destination Point Codes.
