scope:

This European Telecommunication Standard (ETS) defines the stage one of the Eurofile transfer 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 [7]) but does not deal with the details of the human interface itself.

This ETS does define the interworking requirements of private ISDNs with the public ISDN.

This ETS specifies the base functionality where the service is provided to the user via a private ISDN.

This ETS 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 ETS.

The values of the general attributes are outside the scope of this ETS.

The Eurofile teleservice is a service enabling users to exchange files between different types of equipment.

This ETS is applicable to the stage two and stage three ETSs for the ISDN Eurofile teleservice. The terms "stage two" and "stage three" are also defined in CCITT Recommendation I.130 [7]. Where the text indicates the status of a requirement (i.e. as strict command or prohibition, as authorization leaving freedom, or as a capability or possibility), this shall be reflected in the text of the relevant stage two and stage three ETSs.

Furthermore, conformance to this ETS is met by conforming to the stage three ETSs with the field of application appropriate to the equipment being implemented and by conforming to the ETSs on the endto- end characteristics with the field of application appropriate to the equipment being implemented. Therefore, no method of testing is provided for this ETS.
