Abstract

PURPOSE: To avoid continuation of an abnormal broadcast state by providing the function, which generates a false signal, in positions corresponding to ports and terminals of nodes.
CONSTITUTION: A false signal generating part 300 connected to a certain channel of a node device 10 generates the false signal to an input channel if the response signal from a terminating terminal does not come to another input channel of the node device 10 over a prescribed time after arrival of an input signal at said input channel. Each node device 10 fictitiously regards this false signal as the response signal from the destination terminal to said input signal and performs the normal operation to set a link for a corresponding channel. Thus, abnormal states such as transmission and continuation of broadcast of an unnecessary network and unreleasability of the set link is avoided.
