Foreword
This European Telecommunication Standard (ETS) has been produced by the Terminal Equipment (TE)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS defines the basic and recommended additional minimum requirements for terminal equipment
participating in the Teletex service. The terminal described herein offers users the ability to prepare
character coded text messages together with a means of conveying the true contents of such messages to
a distant terminal equipment complying with the same specifications.
Teletex systems such as cluster, Private Automatic Branch Exchanges (PABX), etc., may need additional
requirements. These can be found in Clause 10 of this ETS.
This ETS provides a description of the basic Teletex equipment for use in the international Teletex service.
For optional features the following ETSs apply:
- ETS 300 154: "Terminal Equipment (TE); Terminal characteristics for the telematic file transfer
within the teletex service [ITU-T Recommendation T.571 (1993) modified]" [13].
- prETS 300 243-1 (1993): "Terminal Equipment (TE); Programming Communication Interface (PCI)
Appli/Com for Facsimile group 3, Facsimile group 4, Teletex and Telex services [ITU-T
Recommendation T.611 (1992) modified]" [14].
- prETS 300 243-2 (1993): "Terminal Equipment (TE); Application of ITU-T Recommendation T.611
(1992) and conformance testing on ETS 300 243-1" [22].

1 Scope
This ETS describes the specification to be used for basic Teletex terminal equipment for use in the
international Teletex service.
This ETS is based on the relevant CCITT and ITU-T Recommendations. In order to provide guidance,
modifications and/or additions are also contained and identified where necessary.
