Foreword

IS0 (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)

form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC

participate in the development of International Standards through technical committees established by the respective

organization to deal with particular fields of mutual interest. Other international organizations, governmental and

non-governmental, in liaison with IS0 and IEC, also take part in the work.

In the field of information technology, IS0 and IEC have established a joint technical committee ISODEC JTCl.

Draft Intemational Standards adopted by the joint technical committee are circulated to national bodies for voting.

Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

International Standard ISO/IEC 8882-2 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information

technology.
Annexes A and B of this International Standard are for information only.

Introduction

This part of ISO/IEC 8882 presents the X.25-DTE Conformance Test Suite for the Data Link Layer, described in

Tree and Tabular Combined Notation 0.

Part 1 of ISO/IEC 8882 explains the objectives and usage of this part of ISO/iEC 8882.

Clause 1 of this part of ISODEC 8882 is the scope which provides an objective basis for the applicability of the

tests within this part of ISO/IEC 8882. Clauses 2 and 3 give the references, definitions and abbreviations used in

(this part of ISO/IEC 8882. Clause 4 contains information relating to procedures performed for conformance testing.

The test suite structure is defined in terms of test groups and subgroups in Table 1. This clause also gives an

overview of the test suite. Clause 5 contains the abstract test suite for the X.25-DTE LAPB Data Link Layer

protocol. Finally, Clause 6 provides the abstract test selection rules.

Part 2:
Data link layer conformance test suite
1 Scope

This part of ISO/IEC 8882 defines an abstract test suite for testing the conformance of the Data Link Layer of an

IUT with respect to IS0 7776 or the CCITT Recommendation X.25 (1980,1984).

Conformance of a Data Terminal Equipment (DTE) to the above IS0 International Standard or CCITT

Recommendations is tested using a dedicated circuit between the tester and the DTE. It is noted that CCITT

Recommendations X.25-1980 and X.25-1984 are written from the perspective of a DCE and therefore do not always

explicitly specify the DTE's operation. In such cases it is assumed that recommended operation of a DTE is included

by implication because of the need to communicate with X.25 DCEs. This part of ISODEC 8882 excludes the

testing of the LAP procedures given in the CCIïT Recommendations.

Note: Test cases for extended mode operation (Modulo 128). multilink procedure and DTE-DTE operation as per IS0

7776 are for further study.

The tests in this part of ISOfiEC 8882 are designed for three possible interworking situations, shown in Figure 1.

This part specifies tests for all three cases shown in Figure 1, but recognizes that not every test may apply to a

particular DTE. A test selection procedure has to be performed to determine the applicability of a test to a particular

DTE. Such selection will be based on the PICS and the PIXIT.

otherwise.

a) 0-protocol data unit (N-PDU). In the context of this part of ISO/IEC 8882 (N) is layer 2 and so N-

PDU is abbreviated to PDU. A PDU in the Data Link Layer is also referred to as a "frame".

3.3 X.25-DTE conformance testing terms

This part of ISO/IEC 8882 makes use of the following terms defined in ISO/IEC 8882-1:

a) ImproperPDU
b) ProperPDU
c) Test Case
9, Test Subgroup
e) Tester
---------------------- Page: 8 ----------------------

This test suite uses test subgroups for proper, improper and inopportune frames to test the IUT behaviour. These

terms are defined below.

3.4.1 improper frame: A frame that satisfies one or more of the following conditions:

it is not properly bounded by two flags;
it contains fewer than 32 bits between flags;
it contains a Frame Check Sequence (FCS) error;
it contains an invalid address field encoding;

it contains a command or response control field encoding that is undefined or not implemented in X.25-

DTE LAPB Data Link Layer protocol as specified in IS0 7776;
it is an I frame exceeding the maximum established frame length;

it is an unnumbered or supervisory frame with an information field which is not permitted;

it is a frame with an invalid Ne).

3.4.2 inopportune frame: A syntactically valid frame arriving at a time (DTE's state) when it should be

considered irrelevant by the DTE. Syntactically valid frames are those that are allowed by the X.25 standards for a

DTE using the LAPB procedure and are not covered by 3.4.1.

3.4.3 proper frame: A valid frame arriving at the correct DTE's state or phase and not covered by 3.4.1 or

3.4.2.
3.5 Abbreviations

The abbreviation IUT is used in this part of ISO/IEC 8882 to refer to an X.25-DTE under test.

4 Conformance test suite - Data link layer

The X.25-DTEi Data Link Layer Conformance Test Suite structure is outlined in table 1.

Table 1 - Data link layer test suite structure
Note: Test Group DL8 tests the setting of the system parameters:
T1 - Retransmission timer;
N2 - Maximum number of attempts by IUT to complete a transmission.

The setting of maximum established length and k (window size) are tested under test group Did.

4.1 Data link layer test groups and subgroups

The first seven test groups shown in table 1, called Data Link Layer Test Groups DLl to DL7, are provided to test

the interactive capability of the IUT in every phase. The test groups are further divided into three subgroups

according to the definitions in clause 3.4, above. These are as follows:
Subgroup 1 involves those test cases where the tester transmits a proper frame.

Subgroup 2 involves those test cases where the tester transmits an improper frame.

Subgroup 3 involves those test cases where the tester transmits an inopportune frame.

The eighth test group (DLS) is designed to test the operational correctness of the IUT system parameters listed in

table 1.
