摘要

A remote unit obtains a number of pair to pair cross talk responses from a LAN cable system (14). The pair with the lowest cross-talk performance is selected as a baseline NEXT response. Power sum contribution values for each of the pair-to-pair cross talk responses are obtained from a look-up table (54). Each of the power sum contribution values is subtracted from the baseline cross-talk response to obtain an estimated power sum cross-talk response.
