ABSTRACT:
A repeater apparatus includes a first trunk circuit for receiving and sending data input from and to a first section of the communication link and a second trunk circuit for receiving and sending data input from and to a second section of the communication link. An Isolating circuit is connected to the first trunk circuit for electrically isolating the first section from the second section. For protecting against an overvoltage condition from the communication network, a protection circuit is operatively connected to the first and second trunk circuits. A controller has a first receiver/transmitter circuit for transmitting data from the first trunk circuit to the second trunk circuit, and a second receiver/transmitter circuit for transmitting data from the second trunk circuit to the first trunk circuit. The controller also produces a signal for indicating the completion of data transmission by the first and second receiver/transmitter.
