Omfang

The present document specifies the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the Local exchange (LE) part at the T* or V1* reference points shown in figure 2 of EN 301 141-1 [1]. The present document contains the ATS and partial PIXIT proforma for only the LE side. EN 301 141-2 [2] specifies the Protocol Implementation Conformance Statement (PICS) proforma related to this ATS. EN 301 141-3 [3] specifies the Test Suite Structure and Test Purposes (TSS&TP) related to this ATS and partial PIXIT proforma specification. An NMDS implementation may contain one ISDN-BA port and/or a limited number of PSTN ports up to a maximum of 10. Typically one or two PSTN ports would be supported. The objective of the present document is to provide conformance tests giving a high probability of inter-operability of a Network Termination Node (NTN) and a Local Exchange (LE) by testing the layer 3 aspects of an LE from different manufacturers over the NMDS interface. The present document covers only the procedures described in EN 301 141-1 [1]. ISO/IEC 9646-1 [11] is used as the basis for the methodology of conformance testing. EN 301 141-1 [1] defines the NMDS layer 3 functions in detail: - For the ISDN-BA. - For the PSTN functions. In this case, then bulk of the material shall come from EN 300 324-1 [5].
