Abstract: | ETSI technical committee TISPAN currently funds the development of TTCN-3 network integration test suites using TTCN-3. Specialist task forces (STF) have already been initiated to implement and validate abstract test suites focusing on, e.g., SIP/ISUP and SIP/ISDN interworking units. In this paper, we report on our implementation approach and experiences made in the STF on testing interworking between SIP and ISDN/ISUP. Special attention has been given to the reuse of know-how and of existing TTCN-3 code available due to the existing SIP conformance test suite and the TTCN-3 test framework developed by ETSI for IPv6. Validation has been done using the test laboratory of a telecom network provider. |
