This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols and

Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).

This ETS is part 7 of a multi-part standard covering the V5.2 interface as described below:

Part 3: "Test Suite Structure and Test Purposes (TSS&TP) specification for the network layer (AN

Part 4: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing

Part 6: "ATS and partial PIXIT proforma specification for the network layer (LE side)";

This seventh part of ETS 300 347 contains the Test Suite Structure and Test Purposes (TSS&TP) for the

The objective of this ETS is to provide conformance tests giving a high probability of inter-operability of the

DLL of an Access Network (AN) and a Local Exchange (LE) infrastructure. This ETS covers only the

ISO/IEC 9646-1 [5] and ISO/IEC 9646-2 [6] are used as the basis for the test methodology.

For test definitions of protocol functions which are tested in V5.2 the same way as in V5.1, only reference

ETS 300 347-1 [3] defines the sublayers of the DLL, i.e. Link Access Protocol for V5 interface (LAPV5)

Data Link sublayer (LAPV5-DL), LAPV5 Envelope Function sublayer (LAPV5-EF) and the mapping

function (see ETS 300 347-1 [3], figure 6, which illustrates this approach). Regarding the conformance

testing, these sublayer functions are not tested separately. The test purposes defined in clause 5 cover

testing of the LAPV5-DL (control protocol only), LAPV5-EF and the mapping function. The AN frame relay

function is tested in co-operation with a generic test of an Integrated Services Digital Network (ISDN)

The limitation of the DLL test to the Control DL is based on the assumption that the Public Switched

Telephone Network (PSTN) DL, the Protection DL, the Link control DL and the Bearer Channel

Connection (BCC) DL implementations are identical with the Control DL implementation. This needs to be

declared by the Implementation Under Test (IUT) supplier. Otherwise, the test purposes defined for the
