ISDN conformance test development at NIST

Summary form only given. In the area of ISDN conformance test development NIST's objective is to produce abstract test scripts independent of any test system environment, and to place these test scripts in the public domain. NIST has promoted a cooperative effort amongst interested parties in the industry and a unified conformance effort has been established in the NIU Forum. NIST will maintain a neutral position and serve as a catalyst to the development of test suites in a timely manner. It is planned that test suites for layer 2 (CCITT Q921) and layer 3 (CCITT Q931 or ANSI's equivalent) will be developed first. Currently, NIST is focused on three areas of ISDN conformance testing: a test suite for the layer 2 (LAPD) protocol, test procedures for the layer 1 (I430) protocol, and a TTCN to 'C' translator.<
