20、1 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 186 009-2 1. The TSS the testing architecture; the test methods and port definitions

21、; 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)

22、Proforma of the ATS. Annex B provides the Testing and Test Control Notation (TTCN-3) part of the ATS. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
