ABSTRACT:
A subscriber communication machine is provided with an off-synchronous detector detecting off-synchronization of communication with an office communication machine, a correlation processor, when the off-synchronization is detected, correlatively processing received data received over a communication line and held data having been transmitted from the office communication machine, and a resynchronization controller specifying a synchronous timing by the correlation process in the correlation processor to establish resynchronization in the communication with the office communication machine. When the subscriber communication machine cannot keep synchronization with a transmission cycle in a predetermined transmission system such as TCM in steady communication, it is possible to promptly resume the communication without the necessity for initializing all over again.
