This European Telecommunication Standard (ETS) was produced by the Terminal Equipment (TE)

Technical Committee of the European Telecommunications Standards Institute (ETSI) in May 1990.

This standard describes the Terminal Facility Identifier (TFI) which may be used to ascertain the

capabilities of either a physical Videotex Terminal or another Videotex Service. This ETS is one of an

integrated package of 5 ETSs covering various aspects of videotex which comprises:

Tis standard and its companion ETSs are based on previous CEPT Recommendations and two of them

(Final draft ETSs 300 073 and 300 074) are CEPT Recommendations proposed as endorsed ETSs

For the purposes of this standard, all references within the text to the following T/TE or T/CD numbers

The Terminal Facility Indentifier may be used to ascertain the capabilities of a "terminal", (where a terminal

may actually be a physical terminal or another videotex service). The TFI may be used in three ways:

[2] To determine to which parts of the Service Reference Model (SRM) the terminal

To request the terminal profile the code US 2/0 4/0 is transmitted to the terminal.

The terminal will reply with US 2/0 followed by a series of bytes from columns 4 to 7 of the code table

(profiles and capabilities), or by a series of bytes from columns 4 and 5 of the code table, (representing

the parts of the SRM to which the terminal conforms) terminating with the code 4/0 except when the

To determine whether the terminal can execute a particular VPDE, the service transmits the code US 2/0

followed by the header of the VPDE and terminated by US 2/1 to the terminal. The terminal replies with

either US 2/0 2/0 indicating it can execute the VPDE or with US 2/0 2/1 indicating it cannot execute the

If different levels of conformance are defined in the future (as for the Geometric display or Processable

Data) then the level of conformance may be indicated by one or more bytes from column 3 of the code

For the Geometric mode (primary byte 4/2) the following sub levels will be defined:

A terminal which conforms to parts 1, 2 (sub-level coded 3/9), 4, 5, 6, 8, and 10 would transmit:
