Private Integrated Services Network (PISN); Inter-Exchange Signalling Protocol; Circuit Mode Basic Services; Data Link Layer (DLL); Part 1: Test Suite Structure and Test Purposes (TSS & TP)
This European Telecommunication Standard (ETS) contains the Test Suite Structure (TSS) and Test Purposes (TPs) specification for the Data Link Layer (DLL) of the Private Integrated Services Network (PISN)@ Inter-exchange signalling protocol. The objective of this TSS and TPs specification is to provide conformance tests which give a high probability of inter-operability of the Data Link Layer (DLL). The TSS and TPs specification covers the procedures described in ETS 300 402-2 [1] annex ZA. The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [3] and ISO/IEC 9646-2 [4]) is used as basis for the test methodology. This TSS and TPs specification standard is applicable for use in symmetrical application between two PINXs and is also applicable to equipment when used in certain scenarios that provide a continuous bit stream channel between two PINXs@ and will be referenced from the standard which specifies the scenarios concerned. TSS and TPs specifications for the Network Layer are provided in other parts of the PISN@ Inter-exchange signalling protocol standards.
