ABSTRACT:
A network system includes a transmission line including a plurality of transmission channels, a plurality of transmission equipment connected to the transmission line to effect the transmission and reception of information between each other, and a plurality of devices connected to each of the transmission equipment, thereby effecting the transmission of information between the devices connected to the plurality of transmission equipment. Each of the transmission equipment includes a demultiplexing unit for separating an input signal from the transmission line into a plurality of receiving transmission channels, a channel switch unit for receiving the plurality of receiving transmission channels, outputting designated one of the transmission channels to one of the devices connected to the transmission equipment in question, and receiving transmitting information to form an information transmitting channel and combining it with other channels to be passed to form a plurality of sending transmission channels, and a multiplexing unit for receiving the plurality of sending transmission channels from the channel switch unit to multiplex and output the plurality of sending transmission channels.
