Abstract
A node device is constructed such that the number of relayings can be reduced where communication is performed between terminal equipments connected to this node device. A signal from the terminal equipment is stored in a buffer of the node device. A part of output channels of a connection unit for selecting the output channel of the buffer is guided to a separation unit of this node device. The separation unit separates a signal, which is to be output to the terminal equipment connected to this separation unit, and sends the separated signal to this terminal equipment.
