Test development and test automation for the PacketStar® PSAX product

This paper addresses the requirement for an unambiguous, reproducible and self-documenting test paradigm by applying the ISO/IEC 9646, Information Technology-Open Systems Interconnection-Conformance Testing and Framework test methodology, to telecommunication equipment design verification. The software for Lucent Technologies' PacketStar® (PSAX 1250, PSAX 2300, and PSAX 4500) multi-service media gateways is tested and benchmarked according to ISO/IEC 9646 specifications using a diverse set of automated test tools. The ISO/IEC 9646 specifications provide a robust mechanism to formulate standardized profile test specifications, allowing for quick and accurate feature verification, problem reproducibility, and test coverage that extends to various interworking scenarios. This test methodology, typically used for asynchronous transfer mode (ATM) conformance tests, is expanded to address diverse feature test requirements, including voice over ATM, and to reproduce customer issues.
