Abstract

PURPOSE: To avoid continuation of an abnormal broadcast state, by controlling a connecting means by a monitor leans to disconnect a certain input means from the other input means if this input means continuously receives a going signal over a prescribed time.
CONSTITUTION: A monitor circuit 400 provided in a start control part 60 of a node device forcibly starts the ACK sequence to an input channel from the other channels if the response signal from a terminating terminal does not come to the other input channels of the node device over a prescribed time after arrival of an input signal at this input channel. When the input signal disappears or the reset operation is performed, its link is released to restore the device to the normal state.
