Foreword
This European Telecommunication Standard (ETS) was produced by the Terminal Equipment (TE)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS contains the ETSI agreed and national tests. It is based on, and aligns with, the requirements for
basic Teletex equipment given in the following ETS and ETR:
- ETS 300 015 (1994): "Terminal Equipment (TE); Basic and recommended additional requirements
for terminal equipment supporting Teletex application" [11];
- ETR 052 (1993): "Terminal Equipment (TE); Service intercommunication requirements for Teletex
terminal equipment".
This ETS does not replace CEPT Recommendation T/TE 07-02 (1988), reflecting the current situation for
type approval and certification, and which co-exists with this ETS until it is adopted by ETSI as a full ETS.
Transposition dates
Date of latest announcement of this ETS (doa): 30 November 1994
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 May 1995
Date of withdrawal of any conflicting National Standard (dow): 31 May 1995

1 Scope
This ETS contains and refers to test procedures to facilitate member bodies verification of the protocol and
service conformance of Teletex systems in order to ensure the international compatibility of Teletex.
Furthermore, the specific Teletex service and protocol definitions of ETSI are considered to harmonise the
test procedures for those requirements.
This ETS contains the ETSI agreed test cases which may be used by the ETSI member countries. It also
contains national test requirements.
This ETS is only applicable when considered together with ITU-T Recommendation T.64 [5]. The test
definitions for the related CCITT Recommendations, which define the Teletex service, are not duplicated in
this ETS.
The ETSI and national test procedures contained herein are based on requirements for Teletex systems in
three main areas:
a) conformance testing procedures for Teletex defined in ITU-T Recommendation T.64 [5];
b) characteristics of Teletex equipments, specified in ETS 300 015 [11];
c) characteristics of Teletex equipments for Circuit Switched Public Data Networks (CSPDN) and
Public Switched Data Networks (PSTN) for layers 2 and 3, specified in ITU-T Recommendation
T 70 [6].
Therefore, the test procedures of this ETS cover all ETSI aspects of Teletex which have end-to-end
significance. Thus, tests for the network dependent layers (layers 2 and 3) of CSPDN and PSTN are
included.
These test procedures do not supersede the relevant CCITT, ITU-T and ETSI standards which continue to
be the definitive specifications for all aspects of the Teletex service.
The test procedures of this ETS, together with the test procedures in ITU-T, are intended to assist
verification and cannot fully guarantee the compliance of Teletex systems to the relevant
Recommendations and Standards.
The whole of ITU-T Recommendation T.64 [5] together with this ETS should be applied for a
comprehensive test of a Teletex system.
This ETS refers to ETS 300 015 [11] which is the basis for the European Teletex terminal equipment
specification.
This ETS reflects the definitions ETS 300 015 [11] as far as those requirements are testable or considered
for testing.
Since the interworking with telex service became optional in CCITT Recommendation F.200 [9] and ITU-T
Recommendation T.60 [1], all the tests related to the Teletex/telex interworking are also optional. Only in
the case where the terminal provider declares the terminal supports this option do the tests become
mandatory.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the terms given are as defined in ITU-T/CCITT Recommendations T.60 [1],
T.61 [2], T.62 [3], T.64 [5], T.70 [6], F.201 [10] and CCITT Recommendations T.63 [4], T.90 [7], T.390 [8]
and F.200 [9].
3.2 Abbreviations
For the purposes of this ETS, the abbreviations given are as defined in the CCITT and ITU-T
Recommendations referenced in subclause 3.1.
4 Test limitations
The tests shall establish, to an acceptable degree of reliability, that a Teletex system conforms to the
relevant Recommendations and Standards. It shall not be possible to test for complete conformance due
to:
a) the immense number of state event combinations and possible valid and invalid PDU types which
would require an unacceptably large amount of computational resources and time;
b) the possibility that previous actions may affect the results of a particular test;
c) "transient" states that, although defined in the Recommendations and Standards, may not be
externally accessible. Therefore, the relevant test cases defined in ITU-T Recommendation T.64 [5]
and denoted by "transient state" may, or may not, be used in the ETSI member countries.
