Selected CCS/SS7 GRs

Contact:

This proposed project will involve selected Common Channel Signaling (CCS)/Signaling System 7 (SS7)-related GRs from the following:

• GR-82, Signaling Transfer Point (STP) Generic Requirements
• GR-606, LSSGR: Common Channel Signaling, Section 6.5
• GR-1241, Supplemental Service Control Point (SCP) Generic Requirements
• GR-317, Switching System Generic Requirements for Call Control Using the Integrated Services Digital Network User Part (ISDNUP)
• GR-394, Switching System Generic Requirements for Interexchange Carrier Interconnection Using the Integrated Services Digital Network User Part (ISDNUP)
• GR-905, Common Channel Signaling Network Interface Specification (CCNIS) Supporting Network Interconnection, Message Transfer Part (MTP), and Integrated Services Digital Network User Part (ISDNUP)
• GR-1432, Common Channel Signaling Network Interface Specification (CCNIS) Supporting SCCP and TCAP.

In the area of CCS, Telcordia has developed and published proposed generic requirements to provide:

1. A description of specific functionality to support new capabilities
2. A broad set of requirements that specify network element and network systems CCS-related functions to support a broad range of capabilities
3. Interface specifications to support interconnection between Interconnecting CCS Networks (ICNs) or other network interconnection types [e.g., wireless, Voice over Internet Protocol (VoIP)].

As new capabilities, functions, and interconnection scenarios are identified, or as implementation issues arise with existing requirements, the need to consider modifying this set of requirements is expected to continue. The GRs will be updated to include specifics needed to support VoIP-originated calls over SS7 trunks. The use of new codepoints will be examined, and interconnection scenarios between the Public Switched Telephone Network (PSTN) and VoIP networks will be clearly described. Assumptions will be clearly defined to provide guidance to VoIP providers and equipment vendors.

Modifications to these GR documents are initiated in one of two ways. Technical input, either from a service/network provider, a supplier, or an internal Telcordia source, may lead to an open issue which, for its resolution, may necessitate new or modified generic requirements in one or more of the aforementioned documents.

As part of this project, Telcordia plans to publish new issues, as appropriate, of the aforementioned GR documents, in the fourth quarter of 2008. In addition, one or more Issues List Reports (ILRs) per document may also be published throughout the year, as appropriate, to document and solicit industry feedback on proposed issue resolutions and new open issues.

Interactions with funders may be via letters, telephone calls, conference calls, faxes, and electronic mail, and may also involve group meetings. Funders are also provided access to the CCS Generic Requirements Web site, which contains both Telcordia and publicly available industry information and documentation.

Pursuant to provisions of the Telecommunications Act of 1996, related to the development of industry-wide generic requirements, Telcordia invites all interested parties to participate in this GR project. If your company is interested in participating in this activity, please contact Telcordia. The resulting document(s) will only be available through the purchase of an Enterprise License. Such a license is included in the participation fee for this GR project.

To proceed with this project, it is expected that Telcordia will need at least two industry participants. While the project can proceed with fewer participants, deliverables may change as a result. The participating industry members will be apprised regularly of project status and any changes in deliverables.
