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. 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 W a an xDSL telephone line; and a second xDSL transceiver being in communication with said first xDSL transceiver and said sputter 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. 5. Communication apparatus according to claim 4 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. 6. Communication apparatus according to claim 4 wherein said POTS multiplexing apparatus comprises digital pair gain apparatus. 7. Communication apparatus according to claim 4 wherein said POTS multiplexing apparatus comprises digital loop carrier apparatus. 8. Communication apparatus according to claim 4 wherein said POTS multiplexing apparatus comprises remote switching unit apparatus. 9. A communication system comprising: a remote xDSL transceiver; a PSTN switch; and a substation in communication with said remote xDSL transceiver via at least one xDSL telephone line and said PSTN switch via at least one POTS telephone line, wherein said substation comprises: a first xDSL transceiver for communicating in at least one direction an xDSL transmission via said at least one xDSL telephone line; a second xDSL transceiver for communicating in at least one direction said xDSL transmission with said first xDSL transceiver; and a splitter for communicating in at least one direction a POTS transmission via said at least one POTS telephone line and said xDSL transmission with said second xDSL transceiver. 10. A communication system according to claim 9 and further comprising at least one subscriber telephone line. 11. A communication system according to claim 10 wherein said splitter communicates in at least one direction via said at least one subscriber telephone line. 12. A communication system according to claim 10 wherein said at least one subscriber telephone line comprises a plurality of subscriber telephone lines and wherein said substation multiplexingly communicates via said plurality of subscriber telephone lines. 13. A communication system according to claim 10 and further comprising a low pass filter for communication with said substation via said subscriber telephone line. 14. A communication system according to claim 13 and further comprising POTS apparatus for communication via said low pass filter. 15. A communications system according to claim 9 wherein communication between said remote xDSL transceiver and said substation uses ADSL protocol. 16. A communications system according to claim 10 wherein any of said transmissions via said subscriber telephone line uses either of ADSL protocol and VDSL protocol. 17. A communication system according to claim 1 wherein any of said telephone lines are twisted pair telephone lines. 18. A communication method comprising: transmitting at least one xDSL transmission to a remote substation via at least one xDSL telephone line; transmitting at least one POTS transmission to said remote substation via at least one POTS telephone line; and combining said at least one xDSL transmission and said at least one POTS transmission at said remote substation using at least one splitter; communicating combined xDSL and POTS transmissions to a subscriber's premises telephone network at a subscriber's premises via an xDSL transceiver located at the subscriber's premises; and connecting a telephone to said subscriber's premises telephone network via a frequency filter to provide POTS communications. 19. A communication method comprising: transmitting a plurality of xDSL transmissions bound for a plurality of subscribers to a remote substation via at least one xDSL telephone line; transmitting a plurality of POTS transmissions bound for said plurality of subscribers to said remote substation via at least one POTS telephone line; and combining any of said plurality of xDSL transmissions and any of said plurality of POTS transmissions at said remote substation to form a combined transmission using at least one splitter; multiplexingly communicating said combined xDSL and POTS transmissions to any of said plurality of subscribers at a subscriber's premises telephone network at a subscriber's premises via an xDSL transceiver located at the subscriber's premises; and connecting a telephone to said subscriber's premises telephone network via a frequency filter at a telephone jack to provide POTS communications. 20. Communications apparatus comprising: at least one xDSL transceiver located externally of a subscriber's premises; a standard telephone line connecting said at least one xDSL transceiver directly to a subscriber's premises telephone network; at least one xDSL transceiver located at the subscriber's premises, coupled between said subscriber's premises telephone network and non-POTS apparatus; and a frequency filter located at the subscriber's premises, coupled between said subscriber's premises telephone network and at least one telephone located at said subscriber's premises. 21. Communications apparatus according to claim 20 wherein said subscriber's premises telephone network comprises a subscriber's existing home telephone network and does not require rewiring thereof. 22. Communications apparatus according to claim 20 and further comprising a low pass filter connecting a telephone at a telephone jack to said xDSL transceiver via said standard telephone line and said subscriber's premises telephone network. 23. A method of providing xDSL communications for a subscriber's premises comprising: providing at least one xDSL transceiver externally of a subscriber's premises; connecting via a standard telephone line said at least one xDSL transceiver directly to a subscriber's premises telephone network; coupling at least one xDSL transceiver located at a subscriber's premises to said subscriber's premises telephone network; and coupling at least one telephone located at a subscriber's premises to said subscriber's premises telephone network via a frequency filter at a telephone jack to provide POTS communications. 24. A method according to claim 23 wherein provision of xDSL communication to said subscriber's premises telephone network does not require rewiring thereof.
