An XDSL signal distribution system is provided having a regenerator unit located a predetermined distance from a central office XTU unit for extending the distribution reach of the system. The regenerator is arranged to decode the payload of transmitted XDSL signals into base digital data before repackaging and regeneration onto a twisted pair copper cable. This allows the regenerator to selectively reformat the XDSL signals into a desired protocol format suitable for either an ATM protocol layer, or direct transmission. In addition, the regenerator can retransmit the XDSL signals at a fixed or variable transmission rate to optimize data through-put or system reach.

System and method for increasing distribution distance of XDSL type signals

A system and method for collecting, integrating, and distributing video, data, and telephony signals in a fiber optic communications network for transmission along a twisted copper pair to a customer location. The video, data, and telephony signals are received by a digital subscriber loop access multiplexer and are superimposed onto the twisted copper pair using a service area interface. The system and method enables a customer to receive video, data, and telephony communication data along a single twisted copper pair at relatively high data transfer rates. Additionally, since portions of the existing communication infrastructure are used the cost of implementation is reduced.
