scope:
The present document specifies the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Infonnation for Testing (PIXIT) proforma for the Network Termination Node (NTN) part at the T* or V 1* reference points shown in figure 2 of EN 301 14 1-1 [1]. The present document contains the ATS and partial PIXIT proforma for only the NTN side.
EN 301 14 1-2 [2] specifies the Protocol Implementation Conformance Statement (PICS) proforma related to this ATS.
EN 301 14 1-4 [4] 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 an Network Termination Node (NTN) and a Local Exchange (LE) by testing the layer 3 aspects of an NTN from different manufacturers over the NIvIDS interface. The present document covers only the procedures described in EN 301 141-1 [1].
ISO/IEC 9646-1 [12] 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].
