摘要

The control system of the communication system relates to a control system of a communication system for connecting a plurality of slave stations to a master station apparatus using a common channel. The control unit repeats the power saving control which repeats power supply control to stop or stop or decrease the power supply to the transmitter or receiver while the communication station maintains the communication link based on the power saving permission signal transmitted from the master station equipment A monitoring unit 11C is provided for monitoring synchronization deviation by comparing the synchronization signal included in the band assignment signal with the time of the self apparatus. When the monitoring unit 11C detects the synchronization deviation, the control device shifts from the registered state to the non registered state, and the transmission by the transmitter is stopped.
