Foreword
Part 2 of this European Telecommunication Standard (ETS) was produced by the Terminal Equipment
(TE) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS comprises two Parts:
"Terminal Equipment (TE); Programmable Communication Interface (PCI) APPLI/COM for facsimile group
3, facsimile group 4, teletex and teletex services;
Part 1: CCITT Recommendation T.611 (1992) [modified];
Part 2: Conformance testing".
Transposition dates
Date of adoption of this ETS: 10 November 1995
Date of latest announcement of this ETS (doa): 29 February 1996
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 August 1996
Date of withdrawal of any conflicting National Standard (dow): 31 August 1996
Introduction
This second Part of ETS 300 243 describes the conformance testing of APPLI/COM Programmable
Communication Interfaces (PCIs). ETS 300 243-1 [1] endorses CCITT Recommendation T.611 [2], which
is known as APPLI/COM PCI. As described in CCITT Recommendation T.611 [2], an APPLI/COM PCI is
located within a TE between two entities, a Communication Application (CA) as service provider and a
Local Application (LA) as service user. The services provided by the CA and used by the LA are services
such as sending a document, receiving a document or tracing document transmissions. This second Part
of the ETS describes the testing of the conformance of both entities - CA and LA - with respect to the
interface behaviour.
The reason for providing this Part of the ETS was to give developers assistance in the testing of their
commercial products as well as to make test laboratories able to perform fair testing on different
APPLI/COM products that claim conformance to the APPLI/COM PCI standard. It is expected that CA
testing will be mainly performed by test laboratories, whereas LA testing is rather seen as assistance to
LA developers.
Since no former material exists on which the description of conformance testing of PCIs could rely, the
terminology and notation for describing the testing was deduced from ISO/IEC 9646, Parts 1 to 4 [3].
ISO/IEC 9646 [3] is a general framework for conformance testing of OSI layer protocols. However,
because a PCI is not a protocol, adaptation of certain terms and notations to the requirements of PCIs
were necessary. They are described at appropriate places in this ETS.
Besides the general clauses describing test methodology and adaptation of ISO/IEC 9646 [3], this ETS
contains two separate Abstract Test Suite (ATS) descriptions using (adapted) Tree and Tabular
Combined Notation (TTCN). Hence the testing of either component - CA or LA - can be set up and carried
out independently of each other. In both cases, this ETS tries to provide the shortest list of test cases
necessary to be confident in the conformance of the interface implementation under test. However,
passing the test suites does not guarantee good performance nor does it guarantee reliability in any
environment.

1 Scope
Part 2 of this ETS describes the conformance testing of APPLI/COM Programmable Communication
Interfaces (PCIs) that claim conformance to ETS 300 243-1 [1], which in turn endorses CCITT
Recommendation T.611 [2], with certain ETSI modifications.
The aim of this Part of the ETS is to define conformance tests and methods which ensure, when applied,
that:
- a conforming implementation of a Local Application (LA) can work together with a conforming
implementation of a Communication Application (CA). The LA can coexist, access and communicate
with the CA from within the Terminal Equipment (TE) of the LA;
- a conforming implementation of a CA offers and carries out the functionality and features declared
and covered by one of the functional classes defined by CCITT Recommendation T.611 [2].
The intention of this Part of the ETS is to test one LA to one CA relation.
When many LAs are present within the same TE, many LAs to one CA relation, testing of the LAs need to
handle one LA at a time. To ensure conformance in the case of a many LA to one CA relationship, test
cases are provided exclusively for testing the CA conformance with respect to multiple LAs.
When many CAs are accessible from within the same TE, the testing of the CAs needs to be carried out
one CA at a time. No special test cases are provided for the case of multiple CAs in the same equipment.
2 Normative references
Part 2 of this ETS incorporates by dated and undated references, provisions from other publications.

references the latest edition of the publication referred to applies.
