Patent

CA 2287098

A digital communication trunk employing digital discrete multitone communication over twisted pair copper network segments to increase the effective bandwidth therethrough. Each central office includes an end unit to connect to the network segments and digital discrete multitone repeaters are employed throughout the trunk at defined distances to maintain signal quality. A multiplexer can be employed at the central offices to combine multiple baseband signals before transmission and to extract those multiple signals after reception. In one embodiment of the present invention, four T1 rate baseband signals are combined by the multiplexer into a single signal which is transmitted at T2 rates through the trunk.
