1 Scope
This seventh part of ETS 300 347 contains the Test Suite Structure and Test Purposes (TSS&TP) for the
Data Link Layer (DLL) of the V5.2 Interface.
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
procedures described in ETS 300 347-1 [3] which are based upon ETS 300 125 [1].
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
is made to ETS 300 324-7 [2].
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)
D-channel.
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
Control DL may be used for the other DLs as well.
