Abstract
A loop communication system, interconnecting a number of nodes around the loop, in which two oppositely directed unidirectional loops service the two directions of transmission. Each of the loops comprises a time division multiplexed transmission facility. Each of the nodes has facilities for connecting the communications on each incoming channel to a utilization device connected to that node, for connecting the communication from a utilization device connected to that node to each outgoing channel, or for repeating the communication from any incoming channel to a corresponding outgoing channel. Assignment of a communication to a given channel is accomplished using a centralized control means which causes the communicating devices to be connected using corresponding channels in the two loops, and using that portion of the loop which has the smaller number of intermediate nodes.
