Access and Terminals (AT). 64 kbit/s digital unrestricted leased line with octet integrity (D64U). Connection characteristics

Alkalmazási terület

The present document specifies the technical requirements and test principles for the connection characteristics of ONP 64 kbit/s digital unrestricted leased lines with octet integrity. The leased line provides access to the full digital bit rate of 64 kbit/s, with network timing for both directions of the transmission, with no restrictions on the binary content. 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, and these limits apply only where the terminal output signals are synchronous with the output of the leased line. Together with the companion standard, EN 300 288 [2] defining the network interface presentation, the present document describes the service offered. 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 for leased lines, including part time leased lines, for which the establishment or release does 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 300 288 [2], defines the network interface presentation and places no further constraints on the connection.
