Abstract
Preventing signals from undesirably entering and enabling interactive communication. Signals from a main line or branch line are received by receiving circuits. Signal detecting circuits detect signals, and then transmit the detected signals (detection B and detection A) to a first-arrival judging circuit. The first-arrival judging circuit determines which signal is the first arrival between the signals from the detecting circuits, and then allows one of transmitting circuits to output a signal. Accordingly, only one of the transmitting circuits generates signals, preventing signals of the other transmitting circuit from entering and enabling interactive communication.
