Abstract
A method is provided that includes selectively engaging impedance circuits one at a time from a plurality of selectable impedance circuits in-line with a communication channel. Each of the plurality of selectable impedance circuits includes a hybrid circuit responsive to a modem and to the communication channel. The method further includes determining a performance characteristic for each of the impedance circuits and selecting one of the plurality of selectable impedance circuits for transmission based on the respective performance characteristic.
