Specifies the technical requirements under Section 22 of the Telecommunications Act 1984 for terminal equipment meant for connection to digital leased circuits of the public telecommunications network using CCITT Recommendation G 703 interfaces at a rate of 8448 kbit/s and with a 75 omega unbalanced presentation. Coverage includes conformance principles, electrical characteristics, electromagnetic compatibility, and definitions and abbreviations. Also gives annexes, tables and diagrams.

This Published Document specifies the technical requirements under Section 22 of the Telecommunications Act 1984 for terminal equipment intended for connection to digital leased circuits of the public telecommunications network using CCITT Recommendation G.703 interfaces at a rate of 8448 kbit/s and with a 75 Ω unbalanced presentation. These technical requirements are aligned with Articles 4(c) to 4(f) of Directive 91/263/EEC. This Published Document does not contain any essential requirements for terminal-to-terminal operation via the public network.

This Published Document applies to all terminal equipment that is intended for connection to the form of access referred to above, irrespective of whether the terminal equipment provides additional interfaces, telecommunication services or functions.
