Patent ID: 7593458

Claim:
A method of evaluating operational characteristics of a multi-line, vectored Digital Subscriber Line (DSL) system having a plurality of crosstalking lines in a common communication channel (channel), the method comprising: exciting the plurality of crosstalking lines in the channel with a known sequence of input symbols applied to the crosstalking lines; acquiring output data from a primary line among the plurality of lines in the channel, the output data comprising the known sequence of input symbols after having been affected by crosstalk coupling among the plurality of crosstalking lines in the channel; ordering the crosstalking lines based on a comparison between the known sequence of input symbols used to excite the crosstalking lines and the output data acquired from the primary line; generating a data quantity representative of the crosstalk coupling between the primary line and each of the crosstalking lines based on the ordering of the crosstalking lines; and sending instructions to one or more modems communicatively interfaced with the plurality of crosstalking lines in the channel based on the data quantity generated.
