ITU-T Recommendations

The Q.1238.x series of ITU-T Recommendations defines the Intelligent Network (IN) Application Protocol (INAP) for IN Capability Set 3 (IN CS-3), the INAP for IN CS-3 based upon IN CS-2 Q.1228 and Q.1224 specification (1997) and the general rules for INAP provided in Q.1208, and is consistent with the scope of IN CS-3 as defined in ITU-T Q.1231. Within the Q.123x series of Recommendations, the Q.1238.x series describes the protocol realizing the Q.1231 Distributed Functional Plane in a service and vendor implementation independent manner, as constrained by the capabilities of the embedded base of network technology. This provides the flexibility to allocate distributed functionality into multiple physical network configurations and to evolve IN from IN CS-3 to some future IN CS-N. This Recommendation belongs to Q.1238.x series of ITU-T Recommendations for IN Capability Set 3. It covers the CUSF-SCF interface including the description of the aspects of the CUSF and SCF Functional Entities which are relevant to this interface. This Recommendation includes an electronic attachment containing clause 13 ASN.1 definitions.
