Abstract:
1. A method for optimizing digital subscriber line (DSL) communications performance over a cable bundle having a plurality of loops and including at least one active DSL loop, comprising the steps of: determining, for a new DSL loop communication, a required bit rate of that new DSL loop communication, the determined required bit rate corresponding to a required band of plural adjacent subcarriers numbering less than a total available band of subcarriers on one of the plurality of loops; calculating, for a plurality of subcarrier location positions of the required band of plural adjacent subcarriers for the new DSL loop communication within the total available band of subcarriers, a crosstalk noise effect of the new DSL loop communication with respect to the at least one active DSL loop; choosing a location position for the required band of plural adjacent subcarriers to carry the new DSL loop communication within the total available band of subcarriers where the calculated crosstalk noise effect with respect to the at least one active DSL loop is minimized; and generating a multi-subcarrier DSL signal for the new DSL loop communication having the required band of plural adjacent subcarriers and positioned at the chosen location.
