V interfaces at the digital Local Exchange (LE); V5.1 interface for the support of Access Network (AN); Part 4: Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma specification for the network laye
The present document 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 the V5.1 interface and parts of the system management of the Access Network (AN) 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 AN and a Local Exchange (LE) from different manufacturers over the V5.1 interface.
