A channel assignment system for allowing a plurality of nodes in a loop network, which includes a network control nodes, to hold a duplex communication by time division circuit switching. The network control node is provided with a channel rearrange device. Channels the number of which is smaller than that of the nodes by one are used and, in order that the nodes may be accessed as if they had individual exclusive channels, the channels are logically shifted for rearrangement by the channel rearrange device after each round through the loop. Further, each of the nodes on the loop is provided with a channel rearrange device. Channels the number of which is smaller than that of the nodes are used and, in order that the nodes may be accessed as if they had individual exclusive channels, the channels are logically shifted for rearrangement by the channel rearrange device of each node at each time of data transmission and reception. |
