Foreword
This European Telecommunication Standard (ETS) has been prepared by the Terminal Equipment (TE)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS has been produced in the light of:
a) Videotex services being implemented in different countries using different data syntax profiles (as
described in ETS 300 072 [1]);
b) the International Radio Consultative Committee (CCIR) expressing the view that terminal equipment
1)
compatibility should exist between broadcast Teletext systems for general reception and public
network-based data base systems;
c) the right of different countries to use their existing systems;
d) the possible requirement for transcoding and/or conversion to permit interworking between Videotex
services in different countries;
e) interworking between Videotex services may be provided by using different types of network such
as the Public Switched Telephone Network (PSTN), Packet Switched Public Data Network
(PSPDN), Circuit Switched Public Data Network (CSPDN), Integrated Services Digital Network
(ISDN), etc;
f) the need for Videotex interworking protocols to offer a large degree of compatibility with those
protocols used in other telematic services.
This ETS provides a number of technical provisions to be applied for international interworking between
Videotex services. It specifies the European profile of the international interworking between gateways as
defined in CEPT Recommendation T/SF-59 [2] and ETS 300 105 [3].
This ETS is based upon a number of CCITT Recommendations to facilitate the interconnection of national
Videotex services. The CCITT Recommendations for Videotex interworking are part of the T.500 series of
CCITT Recommendations which contain the application profiles and terminal/gateway characteristics for
telematic services.
NOTE: A full list of references can be found in ETS 300 105 [3], Clause 2 (Normative
references).

1)
The term "Teletext" has not yet been definitively adopted by the CCIR.

1 Scope
This ETS defines no additional features to those contained in the relevant CCITT T.500 series of
Recommendations for Videotex interworking.
This ETS specifies constraints and requirements relevant to ETSI, which are in line with the application
profiles and gateway characteristics defined by CCITT.
While the T.500 series of CCITT Recommendations for Videotex interworking contains an incomplete
provisional section concerning Videotex administrative and charging matters, the CEPT working document
TE1 (87) 87, where principles and functionalities are equivalent to the half duplex mode of operation for
Gateway to Gateway Interworking (GGI), may be used as a reference when implementing the
*
administrative and charging matters in Gateway to Gateway Videotex Interworking .
CEPT Recommendation T/SF-59 [2] and ETS 300 105 [3] define two types of interworking between
national Videotex services:
- international interworking between gateways;
- international interworking between a host and a terminal.
This ETS only applies to the international interworking between gateways.
2 Normative references
This ETS incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest
edition of the publication referred to applies.

These Administrative and charging functions are provisional pending the result of CEPT SF1 and Tg groups and CCITT Study
Groups I, III, and VIII. They shall be brought in line with the result of the work of the above mentioned groups.

4 Relationship with CCITT Recommendations
CCITT Recommendations for Videotex interworking:
- CCITT Recommendation T.504 [4], defines the document application profile;
- CCITT Recommendation T.523 [5], defines the communication application profile;
- CCITT Recommendation T.541 [6], defines the operational application profile;
- CCITT Recommendation T.564 [7], defines the gateway characteristics;
- CCITT Recommendation T.101 [8], contains the principles of interworking architecture, protocols
and the data syntaxes.
CCITT Recommendation T.564 [7] contains the specification of all features that may occur in the
communication between gateways for international videotex interworking, and needs no further
clarification by ETSI.
