ABSTRACT:
A method is provided for reducing crosstalk problems in digital subscriber loop systems. The problems are associated with a second receiver on a second loop responding to a signal from a first transmitter on a first loop. The signal is actually destined for a first receiver and is coupled between the first transmitter and the second receiver as a crosstalk signal. The method includes the step of transmitting a masking signal from a second transmitter to the second receiver for masking said crosstalk signal.
