scope:

The present document specifies the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma based on the Testsuite Structure and Testpurposes defined in TS 186 002-3 [1].

The TSS&TP have been developed to test the interworking between Session Initiation Protocol (SIP) and Bearer Independent Call Control Protocol (BICC) or ISDN User Part, Profiles C. The ATS is sometimes referred to in the present document as 'SIP-ISUP-Interworking ATS'.

The test notation used in the ATS is TTCN-3 (ES 201 873-1 [8]).

The following test specification- and design considerations can be found in the body of the present document:

• the overall test suite structure;

• the testing architecture;

• the test methods and port definitions;

• the test configurations;

 • the design principles, assumptions, and used interfaces to the TTCN3 tester (System Simulator);

• TTCN styles and conventions;

• the partial PIXIT proforma;

• the modules containing the TTCN-3 ATS.

Annex A provides the Partial Implementation Extra Information for Testing (IXIT) Proforma of the ATS.

Annex B provides the Testing and Test Control Notation (TTCN-3) part of the ATS.

NOTE: The current version of the document covers test purposes for SIP-I to ISUP and ISUP to SIP-I basic call and supplementary services only. ATS and PIXIT for ISDN-(ISUP)-SIP-I interworking defined in annex A of TS 186 002-3 [1] will be added in a later version of the present document.
