<p>A network system includes a transmission line (0) including a plurality of transmission channels (C1-C4), a plurality of transmission equipment (1-N) connected to the transmission line (0) to effect the transmission and reception of information between each other, and a plurality of devices (1a, 1b, 2a, 2b, 3a-3c, 4a-4d, 5a-5b, Na-Nc) connected to each of the transmission equipment (1-N), thereby effecting the transmission of information between the devices connected to the plurality of transmission equipment. Each of the transmission equipment (1-N) includes a demultiplexing unit (I3) for separating an input signal from the transmission line (0) into a plurality of receiving transmission channels (C1-C4), a channel switch unit (I6) for receiving the plurality of receiving transmission channels (C1-C4), outputting designated one of the transmission channels to one of the devices connected to the transmission equipment (1-N) 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 (I6) to multiplex and output the plurality of sending transmission channels.</p> |
