Patent ID: 7639596

Claim:
A DSL (Digital Subscriber Line) system comprising: a multiple loop segment comprising a plurality of bonded loops, each loop comprising a twisted pair of wires, the loops being coupled at one end to a controller and at the other end, opposite the controller, to a plurality of different customer premises equipments (CPEs) that are in different locations to provide at least one DSL communications channel to each respective CPE, there being at least one loop coupled to each CPE; the controller to monitor the multiple loop segment and to generate control signals based on the monitoring; and a vectoring unit also coupled to a plurality of the loops of the multiple loop segment at the controller end of the multiple loop segment, to receive the control signals and to vector transmissions simultaneously through the coupled plurality of the loops of the multiple loop segment, the coupled plurality of the loops being coupled to different CPEs, wherein for at least one CPE, a plurality of twisted pairs of wires are coupled to the CPE such that one wire of the plurality of twisted pairs of wires is selected as a reference wire and the other wires of the plurality of twisted pairs of wires are referenced to the reference wire to provide more communications channels than there are twisted pairs.
