SSH TBR 001:1995

Terminal Equipment (TE); Attachment requirements for terminal equipment to be connected to circuit switched data networks and leased circuits using a CCITT Recommendation X.21 interface, or at an interface physically, functionally and electrically compatible with CCITT Recommendation X.21 but operating at any data signalling rate up to, and including, 1 984 kbit/s

Scope

This Technical Basis for Regulation (TBR) specifies the technical characteristics (electrical and mechanical interface requirements, and access control protocol) to be provided by terminal equipment to be connected to Circuit Switched Public Data Networks (CSPDNs) and leased circuits presented at a CCITT Recommendation X.21 [2] interface, or at an interface physically, functionally and electrically compatible with CCITT Recommendation X.21 [2] but operating at any data signalling rate up to, and including, 1 984 kbit/s. The objective of this TBR is to ensure that no disturbance occurs to the public network.
