Abstract

PURPOSE:To prevent an error caused by connecting a communication control unit and a modulator/demodulator when a communication system is established by detecting whether a reception signal element timing signal is present or not and identifying the type of the connected modulator/demodulator. CONSTITUTION:When the modulator/demodulator 2 is synchronizing type, the reception signal element timing signal RT is outputted to the RT detecting circuit 4 of the communication control unit 6 through a signal line 8. The circuit 4 detects, displays and outputs said signal to an informing circuit 5, and further outputs it to a communication control equipment 1, which can identify that the modulator/demodulator 2 connected to the communication control unit 6 is a synchronizing type. If said modulator/demodulator 2 is a start-stop system, the RT signal is not outputted, and the detecting circuit 4 will not output and display the RT signal. Since the informing circuit 5 does not output an informing signal and the communication control equipment 1 does not input a communica tion signal, it is possible to identify that the modulator/demodulator 2 connected to the communication control unit 6 is a start-stop system.
