Overview
SIST ETS 300 222 E1:2003: Terminal Equipment (TE); Framework of Videotex terminal protocols is a Slovenian standard, harmonized with ETS 300 222 Edition 1, prepared by SIST. This standard provides a comprehensive review of all Videotex terminal-related standards, focusing on the protocols that enable terminal-to-host communication across diverse public telecommunications networks.
Videotex is a public access information system that enables various terminal equipment to connect to databases and other terminals via networks such as the Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN). As communication technology evolved-particularly with the emergence of ISDN and advanced modems-the need for clear, interoperable protocols became critical.
Key Topics
- Videotex Terminal Equipment Protocols: The document defines the protocol structure for Videotex terminals, covering application and lower network layers across multiple connection types.
- Supported Network Types:
- ISDN 64 kbit/s circuit mode
- ISDN 64 kbit/s packet mode
- ISDN D channel packet mode
- PSTN packet mode using CCITT (now ITU-T) V. series modems
- Data Syntax Profiles: Outlines the syntax profiles used for representing application data elements in various national and international Videotex implementations. These profiles ensure compatibility and consistent service delivery, as described in related standards (notably ETS 300 072 and ISO 2022).
- Audio and Photographic Enhancements: Identifies common standards for integrating and switching between audio and photographic data within Videotex services, referencing ETS 300 149 and ETS 300 177.
- Conformance Testing: Summarizes approaches to syntax-based Videotex protocol conformance testing.
Applications
- Public Information Services: Videotex protocols serve as the foundational structure for information services delivered over public telecommunication networks.
- Flexible Network Integration: Supports a range of terminal and network configurations, from legacy PSTN-based setups using low-speed modems to high-speed ISDN arrangements.
- Interoperability: By establishing a common framework and referencing key international standards (such as those from ISO and ITU-T), the protocol suite facilitates cross-border compatibility and equipment integration.
- Service Evolution: The flexibility described allows existing Videotex services to migrate from traditional telephony to modern digital networks, ensuring ongoing service relevance.

Practical Value
The framework defined in SIST ETS 300 222 E1:2003 ensures that Videotex terminal equipment from different manufacturers and service operators can reliably interoperate across a variety of network infrastructures. Service providers, system integrators, and equipment designers benefit from the clarity and guidance offered by this standard, which streamlines implementation, testing, and evolution of Videotex-based services. By complying with this framework and its related standards, organizations can achieve robust, scalable, and internationally compatible Videotex solutions.

1 Scope
Videotex is a public access information system which allows for the connection of a variety of terminal
equipment to databases of information (servers) or to other terminals over widely available public
telecommunications facilities. Initially, terminals were connected to information servers over the
conventional Public Switched Telephone Network (PSTN). This was accomplished using low cost
modems: typically at 1 200/75 or 1 200/1 200 bit/s. With the introduction of the Integrated Services Digital
Network (ISDN) and improved modem facilities, a number of other optional configurations are becoming
viable for the connection of Videotex terminals to server systems. These include higher speed
conventional modems at 2 400 or 4 800 bit/s, much higher speed modems such as 9 600 bit/s (CCITT
Recommendation V.29 [18], CCITT Recommendation V.32 [19]) or 14 400 bit/s (CCITT Recommendation
V.17 [17]) and ISDN connections using packet mode on a B or D channel and circuit switched mode.
A number of Videotex communications configurations are possible using these new communications
facilities. This ETS describes the method by which these facilities will be used in Videotex.
This ETS describes the application layer and lower layer protocols which are to be used for terminal to
host Videotex systems operating over various types of networks. This includes:
- ISDN 64 kbit/s circuit mode;
- ISDN 64 kbit/s packet mode;
- ISDN D channel packet mode;
- PSTN packet mode operation using CCITT V. series modems.
In addition, the existing PSTN based Videotex services are identified. These services make use of
relatively low speed modems operating in asynchronous circuit switched mode over the PSTN or
equivalent networks.
This ETS also identifies the data syntax profiles to be used in the various configurations within the various
countries, together with the common data syntaxes for audio and photographic information. The
relationships between the various CCITT Recommendations applicable to Videotex are defined.
