ABSTRACT:
An apparatus and method are provided for bypassing a load coil in a Digital Subscriber Line (DSL) circuit. An interface is provided for making a connection with the DSL circuit and receiving a combined multichannel signal. The combined multichannel signal includes a high frequency or DSL signal and a low frequency signal or voice signal. A high pass filter is utilized to block the voice signal and route the DSL signal over a communications path to bypass the load coil in the DSL circuit. The voice signal is then routed by a low pass filter to the load coil in the DSL circuit.
