1. A system for transmitting data from a general-purpose network to a subcriber data unit using pairs of copper wire such as lines serving subscribers of the conventional telephone system over a distance greater than that generally allowed by said subscriber lines, said system comprising:

  • a general-purpose network-to-subscriber data unit interface, said interface receiving data from a general-purpose network and formatting it for transmission to said subscriber data unit;

    a first broadband transceiver connected to said interface, said first broadband transceiver unit receiving said formatted data from said interface, a second broadband transceiver unit receiving said formatted data in a channel of one or more frequency division multiplexed signals transmitted from said first broadband transceiver via a broadband communication link, said second broadband transceiver removing said formatted data from said channel and transmitting said formatted data to said subscriber data unit via a subscriber line connected to said second broadband transceiver; and

    wherein said second broadband transceiver receives upstream data from said subscriber data unit via said subscriber line, said second broadband transceiver transmits said data in an upstream channel of a frequency division multiplexed signal to said first transceiver, said first transceiver removes said data from said upstream channel and transmits said data to said interface, said interface formats said data received from said first transceiver for transmission to said general-purpose network and said interface transmits said received data from said first transceiver to said general-purpose network.
