Integrated Services Digital Network (ISDN) - Narrowband Multi-service Delivery System (NMDS) - Part 7: Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) specification for the PSTN NMDS interface Layer 3 (NTN side) (incl. Diskette!!!)
The present document specifies the Abstract Test Suite (ATS) and partial Protocol Implementation extra Information
for Testing (PIXIT) proforma for the Network Termination Node (NTN) 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 NTN
side.
EN 301 141-2 [2] specifies the Protocol Implementation Conformance Statement (PICS) proforma related to this ATS.
EN 301 141-4 [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 a
Network Termination Node (NTN) and a Local Exchange (LE) by testing the layer 3 aspects of an NTN 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 [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].
