AbstractA communication server (700) is disclosed and includes a plurality of XDSL transceiver units (710) and a plurality of line interface modules (702). Each line interface module (702) has a plurality of inputs each coupled to a twisted pair data line. Each line interface module (702) also has a plurality of outputs each associated with one of the XDSL transceiver units (710). Each line interface (702) is operable to couple a requesting twisted pair data line to an output associated with a selected XDSL transceiver unit (710). The communication server (700) also includes a network interface (714) that has a plurality of inputs coupled to associated XDSL transceiver units (710). The communication server (700) further includes a system controller (712) coupled to the XDSL transceiver units (710), to the plurality of line interface modules (702) and to the network interface (714). The system controller (712) is operable to select an available XDSL transceiver unit (710) in response to a detected request for data service and to direct the line interface module (702), to which the twisted pair data line requesting data service is coupled, to connect the requesting twisted pair data line to the selected XDSL transceiver unit (710).
