Broadband ISDN remote multiplexer

摘要

A broadband ISDN remote multiplexer, which is constructed by separating a subscriber line interfacing section from an ATM exchange and installing the same at a remote location connected via a high-speed transmission line, comprises: a first interface unit for carrying out conversion between a transmitted signal of UNI format, carrying a destination number in its GFC field and transmitted over a transmission medium interconnecting the ATM exchange and the broadband ISDN remote multiplexer, and a first path-control signal that directs a connection within the remote multiplexer in accordance with the destination number; a plurality of subscriber line interface units for terminating respectively the plurality of broadband ISDN subscriber lines; and a multiplexing/demultiplexing unit for making a connection between the first interface unit and each of the subscriber line interface units in accordance with the first path-control signal.
