Summary

This Recommendation contains the validation (conformance) test specification for ISUP'92 basic call control and signalling procedures. In contrast to Recommendation Q.784.1, where the approach is informal, this Recommendation presents an Abstract Test Suite (ATS), written in TTCN (Tree and Tabular Combined Notation). The main body of this Recommendation presents the requirements regarding the chosen test method, conventions used within the ATS, the test suite structure and the test purposes. Annexes A, B, C and D present the Protocol Implementation Conformance Statements (PICSs), the Protocol Implementation Extra Information for Testing (PIXIT), Protocol Conformance Test Report (PCTR) and the ATS for ISUP'92 basic call control procedures, Annex D being available on electronic media.
