ABSTRACT:
If a communicating terminal connected to a communication line in a private branch exchange system is disconnected from the communication line, then, on the basis of call identifying information contained in an interruption message and in a resumption message, communication is put on hold and is subsequently resumed after the terminal is re-connected. This allows the terminal to be moved between the same or different communication lines while preventing loss of communication.
