A CATV system has a multitude of customer interfaces which include an external unit and an internal unit. The units includes equipment for signal conditioning, cable to telephone interface, and/or cable to computer interface. The internal unit is provided with power by the customer, and the power is used to operate the equipment of the units. The customer supplied power is isolated from the power distributed in the cable television system. Preferably, the customer supplied power is conducted through the coaxial television cable between the internal unit and the external unit. The invention reduces power consumption and allows such customer interfaces to be easily added to existing and future cable systems without overwhelming the existing AC power distribution system of the cable television network.
