Subject:
10 Digit Global Title Translation (GTT) Service
Bell Canada announces the planned introduction of a service to
provide 10 Digit Global Title Translations for portable NPA NXX’s to service
providers. On receipt of a CMS (specifically Automatic Call Back, Automatic Recall and
Screen List Editing) or CNAM (Calling Name database) query containing a subscriber number,
the service provides, where supported, a Destination Point Code and optionally, a
Subsystem Number that can be used to route queries to a network switch or CNAM database
serving the subscriber. The service is expected to be offered by IIIQ98.
The destination point code and subsystem number for final GTT or the destination point
code for intermediate GTT identifying the service provider’s switches/databases will
be dependent on the correct entry of ported number data via the NPAC SMS and the correct
exchange of non-ported number data via the established Industry process.
CMS and CNAM database queries will be dependent on these capabilities being supported
by the switches and databases addressed. These capabilities, while dependent on
10 Digit
Global Title Translations, are external to the 10 Digit Global Title Translation service.
Compatibility Impact:
None expected.
Documentation:
The interfaces are described in technical specifications prepared by the Technical
Interface Subworking Group of the CRTC Interconnection Steering Committee (CISC). The
draft technical specifications as agreed to by the CISC TI SWG are titled
"Network-to-Network Technical Interface for Local Interconnection - Calling Name
Identification Presentation and Restriction" and "Network-to-Network Technical
Interface for Local Interconnection - Call Management Features". The interface
provided by Stentor's 10 Digit Global Title Translation service is described in the CISC
specifications. The TI SWG generates updated versions of the interface specification. It
is the responsibility of all parties to ensure they are using the most up-to-date version
of the specification.
The CISC specifications referenced above are available as MSWord documents
"TICO118.doc " Stentor CMS specification Version 1.1 and
"TICO119.doc" Stentor Calling Name Specification Version 0.3 from the CRTC Web
