In one embodiment, a device (fig. 6) for enabling communications signals over a medium voltage power line includes a first modem (102a), a second modem (102a), a third modem (102b), and one or more switches. The first modem (102a) is electrically coupled to a medium voltage power line (18) and is adapted to receive communications signals from the medium voltage power line. The second modem (102a) is electrically coupled to the medium voltage power line (18) and is adapted to transmit communications signals to the medium voltage power lhe. The third modem (102b) is electrically coupled to a low voltage power line and is adapted to transmit communications signals to the low voltage power line (24). The one or more switches (104) are coupled to the first modem (102a), the second modem (102a), and the third modem (102b), and they are operable to transfer communications signals between two or more of the first modem, the second modem, and the third modem.
