Access and Terminals (AT). 2 048 kbit/s digital unstructured leased line (D2048U). Connection characteristics

Alkalmazási terület

The present document specifies the technical requirements and test principles for connection characteristics of ONP 2 048 kbit/s digital unstructured leased lines. A connection is presented via interfaces at Network Termination Points (NTP) and includes any equipment that may provide the NTP. Signals between terminal equipments are subject to impairments during their transfer over the connection. The limits to these impairments are stated in the present document. Together with the companion standard, EN 300 418 [3] defining the interface presentation, the present document describes the service offered. The leased line provides access to the full digital bit rate of 2 048 kbit/s with no restrictions on the binary content. The tests specified in the present document cannot be carried out, nor can the performance be monitored by the leased line provider, while the leased line is in service, i.e. carrying users' traffic. Thus the tests are designed for bringing into and returning into service, although there is no obligation to perform these tests each time a leased line is brought into or returned into service. 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 specifies the compliance tests for the connection requirements. The present document does not include details concerning the implementation of the tests, nor does it include information on any relevant regulations. The present document describes those characteristics of the connection that cannot be determined only by the equipment providing the NTPs. The related standard EN 300 418 [3] defines the interface presentation and places no further constraints on the connection.
