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 has
been approved by the Network Aspects (NA) Technical Committee of ETSI.
This ETS defines the stage one of the syntax-based Videotex teleservice for the pan-European Integrated
Services Digital Network (ISDN) as provided by European public telecommunications operators. A
Videotex teleservice is an interactive teleservice which provides, through appropriate access by
standardised procedures, users of Videotex terminals the ability to communicate with databases and other
computer based applications via telecommunications networks.

1 Scope
This standard defines the stage one of the syntax-based Videotex teleservice for the pan-European
Integrated Services Digital Network (ISDN) as provided by European public telecommunications
operators. Stage one is an overall service description from the user's point of view (see CCITT
Recommendation I.130 [1]), but does not deal with the details of the human interface itself.
This standard defines the interworking requirements of private ISDNs with the public ISDN.
In addition this standard specifies the base functionality where the service is provided to the user via a
private ISDN.
This standard does not specify the additional requirements where the service is provided to the user via a
telecommunications network that is not an ISDN but does include interworking requirements of other
networks with the public ISDN.
Charging principles are outside the scope of this standard.
The values of the general attributes are outside the scope of this standard.
A Videotex teleservice is an interactive teleservice which provides, through appropriate access by
standardised procedures, users of Videotex terminals the ability to communicate with databases and other
computer based applications via telecommunications networks.
This standard is applicable to the stage three standards for the syntax-based Videotex teleservice. The
term "stage three" is also defined in CCITT Recommendation I.130 [1]. Where the text indicates the status
of a requirement, i.e. as strict command or prohibition, as authorisation leaving freedom, as a capability or
possibility, this shall be reflected in the text of the relevant stage three standard.
Furthermore, conformance to this standard is met by conforming to the stage three standards with the
field of application appropriate to the equipment being implemented. Therefore no method of testing is
provided for this standard.
2 Normative references
This standard 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 standard only when incorporated in it by amendment or revision. For undated references the
latest edition of the publication referred to applies.
