SYSTEM AND METHOD FOR VARIABLE BANDWIDTH TRANSMISSION FACILITIES BETWEEN A LOCAL TELEPHONE SWITCH AND A REMOTE LINE UNIT

摘要

A system and method that uses the flexible bandwidth of a data network in order to provide more flexible services to remote line units comprises a telephone switch configured to provide telephony service to a wireline terminal and an access network head end connected via circuit switch transmission facilities to the telephone switch and configured to manage bearer channels in a data network. The system also includes a data network carrying the bearer channels and a.line unit separate from the telephone switch connected to the data network and to the wireline terminals configured to interface wireline terminals to one of the bearer channels. The access network head end reserves a predetermined bandwidth through the network and allocates a portion of the bandwidth to each of the line units. The amount of bandwidth allocated to each line unit is variable.
