This International Standard describes an arrangement for interconnection of Data Terminal Equipment (DTE), without intermediate Data Circuit-terminating Equipment (DCE), in terms of electrical, mechanical, and functional characteristics. This International Standard applies to DTEs with interface circuits standardised in CCITT Recommendation X.24 for transmission over public data networks. The interconnections are restricted to point-to-point connections.
NOTE — The extension to multipoint configurations is at present under study and would use electrical characteristics according to ISO/IEC 8482 - Information Technology - Telecommunications and Information Exchange between Systems - Twisted pair Multipoint interconnection.
This International Standard applies to DTEs which employ the balanced electrical characteristics of ITU-T V.11 for data signalling rates up to 10 Mbit/s.
The interconnection may be used for start-stop or synchronous transmission. For synchronous transmission, this International Standard applies to DTEs which use circuit X - DTE transmit element timing - and circuit S - Signal element timing - (see clause 5).
An informative annex provides information for the interconnection of DTEs with interface circuits according to ITU-T Recommendation V.24 or with electrical characteristics according to ITU-T Recommendations V.10 or V.28.
