This Recommendation contains the validation (conformance) test specification for ISUP'97 basic call control and signalling procedures defined in ITU-T Recommendation Q.764 [4]. In contrast to ITU-TRecommendation4.784.1 [12], where the approach is informal, this Recommendation presents an abstract test suite (ATS) for ISUP'97 basic call, written in TTCN (tree and tabular combined notation), see [9]. While the tests in Recornmendation Q.784.1 also cover the ISUP as defined in CCITT Recommendation Q.767 [5], this Recommendation applies only to exchanges having implemented the ISUP'97 protocol specification. It is applicable for validation testing of all types of exchanges as defined in the ISuP'97 protocol specification. Note that the compatibility tests are covered by Recommendation Q.784.1.
