Abstract

PURPOSE:To avoid the useless power consumption by securing the power supply only in case the signal transmitter/receiver is connected to the branching direction. CONSTITUTION:Branch repeater 1 is inserted into every place of installation of signal transmitter/receiver 7, and at the same time main communication channel 5 is provided by the route connecting all transmitters/receivers in the shorteset distance with use of repeating connector 8. Then the repeating output of branch repeater 1 inserted to the furthest end is connected to terminator 1 incorporated into repeater 1 to give the termination to channel 5 via signal short circuit line 10. In case transmitter/receiver 7 is connected in the branching direction of repeater 1, distributing connector 12 is used to secure the connection between channel 5 and branch inserting amplifier 2 incorporated into repeater 1 via line 10. At the same time, the connection is given between branch communication line 6 between repeater 1 and transmitter/receiver 7 and power supply line 4 from transmitter/receiver 7 to repeater 2. In such constitution, amplifier 2 is independent from channel 5 as long as transmitter/receiver 7 is not connected to the branching direction of repeater 1. And accordingly, no effect is given to channel 5, and furthermore no power supply 4 is given to avoid the useless power consumption.
