Apparatus for facilitating combined POTS and xDSL services at a customer premises
First Claim
1. An apparatus disposed at a point of entry of a customer premises for facilitating combined xDSL and POTS communication across a two wire pair comprising:
- a first communication port for communication with a central office across a two wire pair;
a second communication port for communication with the customer premises across a two wire pair;
a tap disposed at the first communication port for splitting a combined xDSL and POTS signal into a first and second signal path;
a low pass filter disposed in the first signal path for filtering the xDSL signal from the combined signal in the first signal path;
a circuit disposed in the second signal path, the circuit configured to filter the POTS signal from the combined signal, the circuit further configured to regenerate the xDSL signal, such that the regenerated xDSL signal is transmitted at a lower amplitude and higher frequency than the original xDSL signal of the combined signal; and
an adder configured to combine the POTS signal on the first path with the regenerated xDSL signal on the second path, the adder having an output disposed in communication with the second communication port.

Abstract
In accordance with one aspect of the invention, an apparatus is provided for facilitating combined xDSL and POTS communication across a two wire pair. The apparatus includes a first communication port for communication with a central office across a two wire pair, and a second communication port for communication with a customer premises across a two wire pair. A splitter, or tap, is disposed at the first communication port for splitting a combined xDSL and POTS signal into a first and second signal path. A low pass filter is disposed in the first signal path for filtering the xDSL signal from the combined signal in the first signal path, leaving only the low-frequency (POTS frequency) signals. A circuit is disposed in the second signal path that is configured to filter the POTS signal from the combined signal, leaving only the xDSL signal. The circuit is further configured to terminate the xDSL signal and regenerate it at a lower amplitude and higher frequency than the original xDSL signal of the combined signal. Finally, an adder is configured to combine the POTS signal on the first path with the regenerated xDSL signal on the second path, and output the result to the second communication port (for entry into the customer premises).
