Abstract

PURPOSE: To surely release a communication route, by controlling a connecting means to release fixed connections when input and output signals hold prescribed logical states.
CONSTITUTION: An originating terminal monitors a first return signal transmitted from a terminating terminal in a terminal response monitor time; and when it is detected that this signal is not received, the originating terminal connects all input channels to all output channels to fix the communication route, and each node device 10 performs the sequential control. When the time prescribed by a communication termination detection constant elapses after disappearance of the input signal in some input channel, a termination control part 70 instructs a sequence control part 90 to reset the first arrival input signal detecting part and the input signal detecting part of a start control part 60 to initial states.
