scope:

This fourth part of ETS 300 646 provides the conformance test specification for the second version of the Integrated Services Digital Network (ISDN) - Global System for Mobile communications (GSM) Public Land Mobile Network (PLMN) signalling interface defined in ETS 300 646-1 [1] in compliance with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-1 [6].

This ETS contains the abstract test suite (ATS) for ISUP version 2 for the ISDN-PLMN interface, written in Tree and Tabular Combined Notation (TTCN) as specified in ISO/IEC 9646-3 [8]. It is based on ETS 300 646-3 [3] which specifies the Test Suite Structure and Test Purposes (TSS&TP).

This ETS applies only to exchanges having implemented the ISUP version 2 protocol specification. It is applicable for conformance testing of gateways in the fixed network or in the public land mobile network as defined in the ISUP version 2 for the ISDN-PLMN interface specification ETS 300 646-1 [1]. This ETS does not deal with compatibility testing.

The main text part of this ETS presents the requirements regarding the chosen test method and the conventions used within the ATS.

The annexes present the ATS for ISUP version 2 for the ISDN-PLMN interface (available on electronic media), the partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma and the Protocol Conformance Test Report (PCTR) proforma.
