Foreword
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:
ETS 300 072 Terminal Equipment (TE);
Videotex presentation layer protocol
Videotex presentation layer data syntax
ETS 300 073 Videotex presentation layer data syntax
Geometric Display
(CEPT Recommendation T/TE 06-02, Edinburgh 1988)
ETS 300 074 Videotex presentation layer data syntax transparent data
(CEPT Recommendation T/TE 06-03, Edinburgh 1988)
ETS 300 075 Terminal Equipment (TE);
Videotex processable data
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
without modification.
For the purposes of this standard, all references within the text to the following T/TE or T/CD numbers
should read (unless otherwise stated) as:
T/TE or T/CD 06-01 = ETS 300 072,
T/TE 06-02 = ETS 300 073,
T/TE 06-03 = ETS 300 074,
T/TE or T/CD 06-04 = ETS 300 075,
T/TE or T/CD 06-05 = ETS 300 076.
1 Introduction
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:
[1] To determine the terminal profile and additional terminal capabilities;
[2] To determine to which parts of the Service Reference Model (SRM) the terminal
conforms;
[3] To determine whether the terminal can execute a particular Videotex
Persentation Data Element (VPDE).

4 Coding structure
Two VPCEs are used for the TFI: US 2/0 and US 2/1.
5 Coding
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
Escape code (7/15) is used (see section 5.2).
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
VPDE.
5.1 Conformance to the SRM
The following codes have been assigned for identifying parts of the SRM.
4/0 Terminator
4/1 Alphamosaic (ETS 300 072)
4/2 Geometric (ETS 300 073)
4/3 Photographic (ETS 300 072)
4/4 Define DRCS (ETS 300 072)
4/5 Define Colour (ETS 300 072)
4/6 Define Format (ETS 300 072)
4/7 Transparent data (ETS 300 074)
4/8 Reset (ETS 300 072)
4/9 Processable Data (ETS 300 075)
4/11 Timing Control (ETS 300 072)
A terminal conforming to parts 1, 4, 5, 6, 8 and 10 would transmit:
US 2/0, 4/1, 4/4, 4/5, 4/6, 4/8, 4/10, 4/0.
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
table following the relevant byte from column 4.
For the Geometric mode (primary byte 4/2) the following sub levels will be defined:
3/0 - 3/7 reserved
3/8 - 3/15 sub-levels to be defined are for further study.
A terminal which conforms to parts 1, 2 (sub-level coded 3/9), 4, 5, 6, 8, and 10 would transmit:
US 2/0, 4/1, 4/2, 3/9, 4/4, 4/5
