Patent ID: 8437244

Claim:
A method of determining a selection of lines to which to apply crosstalk cancellation, the method comprising: determining a metric corresponding to crosstalk interference for each line of a set of lines; setting a threshold level for the metric; allocating a respective resource to each line meeting the threshold level, the respective resources configured to cancel crosstalk interference in the lines meeting the threshold; determining total resources allocated to all lines meeting the threshold level; determining if the total resources are within a target range; and if the total of resources is not within the target range, resetting the threshold level and repeating the act of allocating until the total resources allocated is within the target range, wherein resetting the threshold level includes setting a new threshold level by changing the threshold level corresponding to one of a fixed amount and a percentage, clearing a line marker for each of the set of lines, monitoring each line for a change in status, and setting a corresponding line marker on each line meeting the new threshold level upon a change in status.
