Abstract
A node apparatus is used in a communication network having a multi-conjunction architecture. The communication network has a plurality of transmission paths each coupling one node apparatus to another node apparatus or a terminal device. The node apparatus generally comprises an input port, an output port, and a control part for controlling the coupling of input channels of the input port to output channels of the output port. The control part disconnects and releases a fixed communication path when a certain logic state of a signal continues for a predetermined time period after the communication path is fixed. This predetermined time period is variable and is determined depending on a characteristic of the signal to suit a protocol of the communication.
