Access and Terminals (AT). 2 048 kbit/s digital unstructured and structured leased lines (D2048U and D2048S). Network interface presentation

Alkalmazási terület

The present document specifies the technical requirements and test principles for the network interface presentations of ONP 2 048 kbit/s digital leased lines using 120 ? interfaces. This includes: - the 2 048 kbit/s digital unstructured leased line; and - the 2 048 kbit/s digital structured leased line with an information transfer rate of 1 984 kbit/s without restriction on binary content. A connection is presented via interfaces at Network Termination Points (NTP). 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 300 247 [3] or EN 300 419 [5] , specifying the connection characteristics between the NTPs of the leased line. The present document and the appropriate connection characteristics standard together describe the technical characteristics of the leased line. The present document is applicable to leased lines, including part time leased lines, for which the establishment or release do not require any protocol exchange or other intervention at the NTP. The present document covers the physical, 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, or returned into, service.
