Summary

This Recommendation gives guidance to Administrations, specifiers of SCCP applications and implementors on a number of specific issues related to the incorporation of SCCP in actual networks. These guidelines aim to provide a common understanding and hence to enhance the interoperability between networks and implementations. The aim is to give guidance only, it is not intended to extend, change, nor restrict the normative clauses in ITU-T Recs. Q.711 to Q.714. The following topics are covered in this Recommendation:

•            Compatibility issues: This Recommendation identifies changes between the different revisions of the SCCP Recommendations and discusses the effect on the interaction between implementations according to the different revisions. Where incompatibilities are unavoidable, engineering measures and evolution strategies are considered.

•            Addressing issues: The meaning of the different addressing parameters and options is explained. A procedure is provided so that an application specifier can derive the needs and requirements on the addressing in the underlying SCCP layer.

•            Networking issues: The possibilities of SCCP routing and management are explored to create particular network structures. Also networking issues pertaining to connectionless or connection oriented services are discussed. Architecture and interworking issues related to broadband SCCP enhancements are also covered.
