1. A point to point facility transport system for the transport of Ethernet frame data over a copper infrastructure connecting a central office facility to a customer premise, comprising:

  • a downstream transmission path for transporting Ethernet frame data transmitted from the central office facility destined to the customer premise, said downstream transmission path operative to simultaneously carry both voice and Ethernet data signals;

    an upstream transmission path for transporting Ethernet frame data transmitted from the customer premise destined to the central office facility, said upstream transmission path operative to simultaneously carry both voice and Ethernet data signals;

    said downstream transmission path and said upstream transmission path being symmetrical in data transmission capacity, the Ethernet transmission capacity of said downstream transmission path being substantially the same as the Ethernet transmission capacity of said upstream transmission path;

    first modem means located at the central office facility and coupled to one end of said downstream transmission path and one end of said upstream transmission path;

    second modem means located at the customer premise and coupled to the other end of said downstream transmission path and the other end of said upstream transmission path; and

    wherein said first modem means and said second modem means are operative to place onto and receive from the copper infrastructure data frames encapsulating said Ethernet frame data.
