Recommendation Q.781

MTP LEVEL 2 TEST SPECIFICATION

1 Introduction

This Recommendation contains a set of detailed tests of signalling system No. 7 MTP level 2 protocol. These tests intend to validate the protocol specified in Recommendation Q.703.

This Recommendation conforms to Recommendation Q.780 which describes the basic rules of the Test Specification. In addition the conditions which are specific to level 2 tests are described in the following sections.

2 General principles of level 2 tests

2.1 Presentation of test descriptions

The level 2 tests aim at testing the level 2 protocol conformance in a given implementation.

Each test description indicates in the ``type of test'' column; ``Validation'' (VAT) or ``Validation'' (VAT) and ``compatibility'' (CPT).

Although signal units are transmitted and received continuously on level 2, only the signal units which cause and/or indicate the changes of level 2 status are shown in the EXPECTED SIGNAL UNIT SEQUENCE column of each test description.

2.2 Presentation of the test list

These tests as a whole, aim at a complete validation of the level 2 protocol without redundancies. Each test is described as simply as possible to check precisely each elementary function of the protocol, which is referred in the columns ``reference'', ``title'' and ``sub-title'' of each test description.

This list is presented in the form of a succession of tests. The presentation order is essentially functional. However, the operator performing these tests may change this order, taking into account some other practical criteria such as: use pre-test conditions to order the list, the end of a given test may be the pre-test condition of another test.

3 Test configuration

A single link will be used for level 2 tests. Figure 1/Q.781 shows a single link between SP A and SP B. Test specifications are written to test the level 2 of the SP A.

4 Test environment

See Recommendation Q.780, § 6.2.

5 Test list

Note -- Compatibility test items are indicated in this list by an asterisk (*).

-- The abbreviations PO , LPO , RPO , EM and EDA are used for processor outage, local processor outage, remote processor outage, emergency and expected delay of acknowledgement respectively.
