ABSTRACT:
A combination power and communication line protection apparatus includes a housing which contains a power line plug adapted to be received by a conventional wall power receptacle and a receptacle suitable for receiving a male line plug from equipment to be protected in addition to a pair of communication line or modular phone jacks into which an outgoing communication line may be received together with a data link communication line in parallel therewith. The apparatus provides an overvoltage protection for a pair of communication lines and an overvoltage surge protector for the power lines and utilizes the power line ground connection to provide the necesssary ground to protect the communication lines from overvoltages thereon.
