a second xDSL transceiver being in communication with said first xDSL transceiver and said splitter, and wherein

said first xDSL transceiver comprises a plurality of first xDSL transceivers; and

wherein

said communication apparatus further comprises;

inverse multiplexing apparatus in communication with any of said plurality of first xDSL transceivers.

2. Communication apparatus according to claim 1 and further comprising remote powering apparatus for receiving power over a standard telephone line.

3. Communication apparatus according to claim 2 wherein said standard telephone line is operative to convey said xDSL transmission.

4. A communication system according to claim 1 wherein any of said telephone lines are twisted pair telephone lines.

5. Communication apparatus comprising:

a first xDSL transceiver for conveying an xDSL transmission;

a splitter for conveying a POTS transmission via a POTS telephone line and said xDSL transmission via an xDSL telephone line; and

a second xDSL transceiver being in communication with said first xDSL transceiver and said splitter wherein said splitter comprises a plurality of splitters and wherein said communication apparatus further comprises POTS multiplexing apparatus in communication with said plurality of splitters.

6. Communication apparatus according to claim 5 wherein said POTS multiplexing apparatus receives a combined POTS transmission of a plurality of POTS transmissions and multiplexingly communicates said plurality of POTS transmissions via said plurality of splitters.

7. Communication apparatus according to claim 5 wherein said POTS multiplexing apparatus comprises digital pair gain apparatus.
