Abstract
A physical layer transceiver, for connecting a host device to a wireline channel medium having a cable length, includes a host interface for coupling to a host device, a line interface for coupling to the channel medium, and filter circuitry operatively coupled to the line interface. The filter circuitry includes a plurality of filter segments, fewer in number than a total number of link segments in the cable length. Individual filter segments in the plurality of filter segments are configurable to correspond to individual link segments, and are separately controllable from other filter segments. Control circuitry detects a change of transmission conditions in a particular link segment, and upon detection of the change of transmission conditions, changes a configuration of one of the plurality of filter segments to cause an alteration in filtering of signals in the particular link segment at which the change of transmission conditions is detected.
