Описание
The present document contains the Test Suite Structure (TSS) and Test Purposes (TPs) for the Network layer (NWK)
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 conformance tests giving a high probability of inter-operability of
an AN and a Local Exchange (LE) from different manufacturers over the V5.1 interface. The present document covers
only the procedures described in EN 300 324-1 [1].
ISO/IEC 9646-1 [5] is used as the basis for the methodology of conformance testing.
Concerning the Public Switched Telephone Network (PSTN) protocol testing, only the procedures defined in
EN 300 324-1 [1] are covered by the tests defined in the present document. An Implementation Under Test (IUT),
however, will have implemented a national PSTN protocol part as well. This requires that the tester generates messages
containing the national PSTN protocol specific optional Information Elements (IEs), otherwise the IUT would not act
on messages according to the PSTN protocol procedure definition. However, this does not provide a comprehensive test
of the national PSTN protocol mapping specification, which is outside the scope of the present document.
As the tests use PSTN messages containing optional IEs according to national specifications, the test result is only valid
for the implemented national mapping of the V5.1 PSTN protocol.
The present document does not cover tests related to functions of the bearer channel. Those functions should be tested
in conjunction with testing of the national PSTN protocol mapping specification.
The present document contains no requirements concerning NWK tests for Integrated Services Digital Network Basic
Access (ISDN-BA).
