ABSTRACT:
A system for detecting the transmission direction of a signal on a two-say transmission line, in which a switch is inserted in the two-way transmission line while a signal detector is connected to the two-way transmission line at one side of the switch. Two signal detectors may be connected to the two-way transmission line at both sides of the switch respectively. If the switch has two selected contacts, the two signal detectors are connected to the selected contacts respectively. The switch is switched in response to the output of the signal detector or the outputs of the two signal detectors. The transmission direction of the signal on the two-way transmission line is detected in accordance with the state of the signal detector and the states of the two signal detector after the switching of the switch.
