1. A device for communicating data signals over a power line carrying a voltage greater than one thousand volts, comprising:

  • a first port configured to communicate over the power line;

    a network interface configured to communicate over a non-power line communication medium;

    a first amplifier forming part of a first communication path between said first port and said network interface, said first amplifier configured to amplify downstream data signals transmitted via said first port;

    wherein at least some downstream data signals traverse said first communication path without demodulation;

    a second amplifier forming part of a second communication path between said first port and said network interface, said second amplifier configured to amplify upstream data signals received via said first port; and

    wherein at least some upstream data signals traverse said second communication path without demodulation.
