In particular, the following terms apply: Abstract Test Case (ATC): complete and independent specification of the actions required to achieve a specific test purpose, defined at the level of abstraction of a particular Abstract Test Method, starting in a stable testing state and ending in a stable testing state (see ISO/IEC 9646-1, clause 3.3.3) Abstract Test Method (ATM): description of how an IUT is to be tested, given at an appropriate level of abstraction to make the description independent of any particular realization of a Means of Testing, but with enough detail to enable abstract test cases to be specified for this method (see ISO/IEC 9646-1, clause 3.3.5) Abstract Test Suite (ATS): test suite composed of abstract test cases (see ISO/IEC 9646-1, clause 3.3.6) Implementation Under Test (IUT): implementation of one or more OSI protocols in an adjacent user/provider relationship, being part of a real open system which is to be studied by testing (see ISO/IEC 9646-1, clause 3.3.43) ISDN number: number conforming to the numbering and structure specified in ITU-T Recommendation E.164 Means of Testing (MOT): combination of equipment and procedures that can perform the derivation, selection, parameterization and execution of test cases, in conformance with a reference standardized ATS, and can produce a conformance log (see ISO/IEC 9646-1, clause 3.3.54) PICS proforma: document, in the form of a questionnaire, which when completed for an implementation or system becomes the PICS SIST EN 300 356-33 V3.2.2:2003

Figure 1/ITU-T Recommendation Q.784.2 [10]: Exchange as SUT The implementation under test (IUT) is the ISUP '97 implementation in this exchange, as shown in figure 1/ITU-T Recommendation Q.784.2 [10]. The aim of the ISUP implementation is to assure capabilities and functions for circuit and signalling supervision on one hand and for call handling on the other. Circuit supervision is done mainly through the MMI (man machine interface) of the exchange. The MMI interface is implementation dependent and thus not standardized. The effects of signalling procedures of the ISDN User Part can be observed on the NNI (network-network interface), on the circuits controlled by the ISUP. The ISUP signalling protocol can be observed on the SS7 link on the NNI. The ISUP implementation will in some exchanges have to interwork with the access signalling system on the UNI (user-network interface) and involve call handling in order to establish end-to-end connec
