Abstract

See full text

A communication server (58) includes a plurality of pairs of frequency agile modulators (638) and demodulators (640) each set to operate at a unique frequency and associated with a twisted pair data line (54). The communication server (58) also includes a plurality of pairs of demodulators (644) and modulators (646) that each have a designatable operation frequency and are associated with one of a plurality of XDSL modems (648). A mixer (642) operates to combine signals from the frequency agile modulators (638) and provide the combined signal to the demodulators (644). The mixer (642) further operates to combine signals from the modulators (646) and provide the combined signal to the frequency agile demodulators (640). A detector (634) operates to detect a need for data service on a selected twisted pair data line (54). The controller (636) then operates to couple the selected twisted pair data line (54) to the selected XDSL modem (648) by designating the demodulator (644) and modulator (646) pair associated with the selected XDSL modem (648) to operate at the unique frequency of the frequency agile modulator (638) and demodulator (640) associated with the selected twisted pair data line (54).
