Access and Terminals (AT). 34 Mbit/s and 140 Mbit/s digital leased lines (D34U, D34S, D140U, D140S). Network interface presentation

Alkalmazási terület

The present document specifies the technical requirements and conformance tests for the network interface presentations of 34 Mbit/s and 140 Mbit/s digital leased lines. This includes: - the 34 Mbit/s Digital Unstructured leased line operating at 34 368 kbit/s; - the 140 Mbit/s Digital Unstructured leased line operating at 139 264 kbit/s; - the 34 Mbit/s digital structured leased line operating at 34 368 kbit/s for the support of an unstructured 33 920 kbit/s information transfer rate; - the 140 Mbit/s digital structured leased line operating at 139 264 kbit/s for the support of an unstructured 138 240 kbit/s information transfer rate. A connection is presented via interfaces at Network Termination Points (NTPs). The present document defines the network interface as presented by the leased line provider and should be used in conjunction with the appropriate companion standard, EN 300 687 [6] (34 Mbit/s) or EN 300 688 [7] (140 Mbit/s), which specifies the connection characteristics between NTPs of the leased line. The present document and the appropriate connection characteristics standard together describe the technical characteristics of the relevant leased line. The present document is applicable to leased lines, including part time leased lines, whose establishment or release does not require any protocol exchange or other intervention at the NTP. The present document covers the mechanical and electrical characteristics (except safety, overvoltage and EMC aspects) of the network interface and specifies the conformance tests for equipment of the kind that provides the interface presentation. Some of the tests described in the present document are not designed to be applied to the interface of an installed leased line; such tests may be applied to equipment of the kind used to provide the interface. The present document does not include details concerning the implementation of the tests nor does it include information on any regulations concerning testing. There is no requirement for each leased line to be tested in accordance with the present document before it is brought into service or returned into service following repair.
