1 Scope

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

network layer and parts of the system management of the Access Network (AN) side of a V5.2 interface.

The objective of this ETS 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 V5.2 interface. This ETS covers only

the procedures described in ETS 300 347-1 [2].

ISO/IEC 9646-1 [4] and ISO/IEC 9646-2 [5] are used as the basis for the test methodology.

This ETS needs to be read in conjunction with ETS 300 324-3 [1]. The two documents share a common

format and clauses within ETS 300 324-3 [1] are directly referenced.
Annex A lists the bibliography.
2 Normative references

This ETS incorporates by dated and undated reference, provisions from other publications. These

normative references are cited at the appropriate places in the text and the publications are listed

hereafter. For dated references, subsequent amendments to or revisions of any of these publications

apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest

edition of the publication referred to applies.

4.3 Test step structure

General dynamic behaviours are described in test steps which can be called from all test cases within the

Abstract Test Suite (ATS):
state transitions (refer to subclause 4.3.1);
preconditions (refer to subclause 4.3.2);
preambles (refer to subclause 4.3.3);
postambles (refer to subclause 4.3.4);
status verification (refer to subclause 4.3.5);
common test steps (refer to subclause 4.3.6).
4.3.1 State transitions

The following subclauses identify the test steps used in the ATS. In general, each test step represents a

state transition. For example in the PSTN protocol, PSTN_AN1_2 is the test step which brings the AN

PSTN protocol FSM from PSTN_path_state AN1 to PSTN_path_state AN2. The state transitions are

declared in the parenthesis (originating state - destination state) which follow the test step names.

Six groups of state transitions are defined:

STARTUP start up the V5 interface and put the Implementation Under Test (IUT) into the initial

state as defined in subclause 5.1.5.

CTRL state transitions used to preamble and postamble the Control protocol before a test

purpose can be performed.

PSTN state transitions used to preamble and postamble the PSTN protocol before a test

purpose can be performed.
LINK state transitions used to pre
