Summary

IN Capability Set 2 (IN CS-2) is the second standardized stage of the intelligent network as an architectural concept for the creation and provision of telecommunication services. This Recommendation provides the Intelligent Network (IN) Global Functional Plane (GFP) architecture for IN Capability Set 2 (IN CS-2). This Recommendation defines the IN GFP for IN CS-2 based on the general framework for IN GFP provided in Recommendation Q.1203 [2], consistent with the scope of IN CS-2 defined in Recommendation Q.1221 [3].

This Recommendation defines:

–           the IN GFP model for IN CS-2 in terms of a subset of the general IN GFP model;

–           identifications and definition of the 21 IN CS-2 Service Independent Building-blocks (SIBs), including the Basic Call Process (BCP) and the Basic Call Unrelated Process (BCUP) specialized SIB;

–           the use of global service logic in IN CS-2.

Companion Recommendations include the Q.120x- and Q.122x-Series of Recommendations.
