<p>PURPOSE:To provide the method and device which automatically matches monitor data from a monitor and control equipment in the phase of the clock of a main signal. CONSTITUTION:The automatic phase adjustment device of a communication system which sends the clock of the main signal from a communication device 50 to the monitor and control equipment 51, sends the data from the monitor and control equipment 51 to the communication device 50 in synchronism with the clock, and multiplexes the data with the main signal of the communication device 50 and sends them to an opposite-side communication device is equipped with a phase comparing circuit 52 which compares the phase of the clock outputted from the communication device 50 to the monitor and control equipment 51 with the phase of the data inputted from the monitor and control equipment 51 to the communication device 50 on the communication device side and a phase control circuit 53 which adjusts the phase of the clock supplied from the communication device 50 to the monitor and control equipment 51 according to the phase comparison result of the phase comparing circuit 52 so that the clock matches the data in phase on the communication device side.</p> |
