The Standardization of Core INAP CS-2 by ETSI

The development of the Core INAP CS-2 standard and the corresponding conformance test suites by expert teams at the European Telecommunications Standards Institute (ETSI) are historical breakthroughs for the use of SDL and MSC within the international telecommunications standardization process. For the rst time, the textual description of a standard has no priority over the corresponding SDL speci-cation, which in the case of Core INAP CS-2 is published as a normative annex to the protocol standard. The power of a standard SDL speciication has been shown by the successful application of computer aided test generation methods for the production of the necessary standard conformance test suites. This paper introduces the Core INAP CS-2 protocol speciication and describes the test generation procedure.
