1. A communication server coupled to a plurality of twisted pair data lines, each twisted pair data line coupled to an associated twisted pair subscriber line by a splitter, the communication server comprising:

  • a plurality of line interface units, each line interface unit coupled to an associated twisted pair data line and coupled to an associated receive data pair and transmit data pair;

    a plurality of XDSL modems, each XDSL modem coupled to an associated modem receive data pair and transmit data pair;

    a switch coupled to the receive data pair and transmit data pair of each line interface unit, the switch also coupled to the modem receive data pair and transmit data pair of each XDSL modem, the switch operable to couple a selected subset of the receive data pairs and transmit data pairs of the line interface units to the modem receive data pairs and transmit data pairs of the XDSL modems;

    a detector operable to detect a need for data service on a receive data pair of a selected line interface unit; and

    a controller coupled to the detector and to the switch, the controller operable to select one of the XDSL modems in response to detecting the need for data service, the controller further operable to direct the switch to couple the receive data pair and transmit data pair of the selected line interface unit to the modem receive data pair and transmit data pair of the selected XDSL modem.
