Abstract:
1. A method of reducing crosstalk problems in a digital subscriber loop (xDSL) system, said xDSL system including a first xDSL transceiver unit (xTU), a second xTU, a first loop coupling said first xTU and said second xTU; a third xTU, a fourth xTU, and a second loop coupling said third xTU and said fourth xTU, wherein a crosstalk signal results from crosstalk between said first loop and said second loop, said method comprising the steps of: transmitting an xDSL signal on said first loop from said first xTU to said second xTU, wherein said xDSL signal results in said crosstalk signal on said second loop; and transmitting a masking signal on said second loop from said third xTU to said fourth xTU, wherein said masking signal masks said crosstalk.
