1996 Testing of Communicating Systems  
Global System for Mobile communication (GSM) is a European standard which defines telecommunication services for mobile subscribers. At the end of 1995, the European Telecommunication Standard Institute (ETSI) released the Mobile Application Part (MAP) version 2 protocol which supports signalling between GSM phase 2 network entities. It also provided the corresponding conformance test purpose specification. The testing of this protocol involved numerous interfaces and thus required multi-party

It demonstrates the importance of completeness in test purpose specification and the advantage of allocating substantial resources to both ATS development and ATS validation to ensure ATS quality. It also presents a TTCN style guide in order to improve maintenance tasks. It describes some TTCN deficiencies and proposes enhancements.
