This sixth part of EN 300 324 contains the Abstract Test Suite (ATS) as well as the Abstract Test Method (ATM) and
the partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the Network layer (NWK) of a
V5.1 interface and parts of the system management of the Local Exchange (LE) side of a V5.1 interface.
The objective of the present document is to provide an ATS containing conformance tests which give a high probability
of inter-operability of an Access Network (AN) and a LE from different manufacturers over the V5.1 interface.
ISO/IEC 9646-1 [5] and ISO/IEC 9646-2 [6] are used as the basis for the test methodology. The ATS is defined using
the Tree and Tabular Combined Notation (TTCN) according to ISO/IEC 9646-3 [7].
The ATS in annex A describes a set of Test Cases (TCs) which are based on the Test Purposes (TPs) specified in
EN 300 324-5 [3]. The TCs provide the implementation of the TPs and can be converted into an executable test suite by
using available TTCN translators and the corresponding tools.
Annex B provides the partial PIXIT proforma.
