摘要： A digital subscriber line (xDSL) communication system (10) is disclosed that allows xDSL communication across a local loop. The system (10) includes a local loop termination point (14) and customer premises equipment (12) connected to a twisted pair telephone line (16). Loop integrity test devices (22, 24) for xDSL communication are located at the local loop termination point (14) and the customer premises equipment (12) and are coupled to the telephone line (16). The loop integrity test devices (22, 24) are respectively operable to transmit test signatures across the telephone line (16), to receive and evaluate test signatures from the telephone line (16), and to indicate whether the telephone line (16) can support xDSL communication based upon evaluation of test signatures.

摘要： A remote XDSL transceiver unit (16) includes an XDSL transceiver (19) and a control block (18). The XDSL transceiver (19) is operable to establish and communicate across an XDSL physical layer. The control block (18) is coupled to the XDSL transceiver (19) and operates to transmit a request for service to a loop termination point. The control block (18) also operates to identify a signal received from the loop termination point (14) and respond based upon a current context of the remote XDSL transceiver unit (16). Further, the control block (18) operates to control power-up and training of the XDSL transceiver (19) such that the XDSL physical layer can be dynamically brought up and down. In one embodiment, the control block (18) operates to store profile information for an established XDSL physical layer to use for future re-establishing of the XDSL physical layer.

摘要： 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).

摘要： A communication server (58) is provided that includes a plurality of line interface units (500) each coupled to an associated twisted pair data line (54) and to an associated receive data pair (506) and transmit data pair (504). A plurality of XDSL modems (510) are coupled to associated modem receive data pairs (514) and transmit data pairs (512). A switch (502) operates to couple a selected subset of the receive data pairs (506) and transmit data pairs (504) of the line interface units (500) to the modem receive data pairs (514) and transmit data pairs (512) of the XDSL modems (510). A detector (508) operates to detect a need for data service on a receive data pair (506) of a selected line interface unit (500). A controller (80) operates to select one of the XDSL modems (510) in response to detecting the need for data service and to direct the switch (502) to couple the receive data pair (506) and transmit data pair (504) of the selected line interface unit (500) to the modem receive data pair (514) and transmit data pair (512) of the selected XDSL modem (510).

摘要： A communication server (58) using digital signal switching is provided. A plurality of twisted pair subscriber lines are split into twisted pair data lines (54) and twisted pair phone lines (52). Analog signals received on the twisted pair data lines (54) are converted into incoming parallel digital words and outgoing parallel digital words are converted into analog signals for transmission on the twisted pair data lines (54) using first converters (614) coupled to each twisted pair data line (54). The incoming parallel digital words are converted into incoming serial bit streams and outgoing serial bit streams are converted into the outgoing parallel digital words using second converters (616) coupled to the first converters (614). A need for data service is detected on a selected twisted pair data line (54), and one of the XDSL modems (620) is selected in response to detecting the need for data service. The selected XDSL modem (620) is then coupled to a second converter (616) associated with the selected twisted pair data line (54) where the selected XDSL modem (620) receives the incoming serial bit stream from and provides the outgoing serial bit stream to the associated second converter (616).

摘要： 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).
