Abstract
A configuration control method for a double loop communications system capable of handling simultaneously two different traffic modes for packet data and circuit-switched data, which includes a selector for connecting a token passing control circuit to either a hybrid multiplexer or a transmission line interface circuit to fully utilize the resources of the double loop transmission lines to increase the system throughput and handle both packet data and circuit-switched data in the event of fault occurrence without increasing the overhead for the fault recovery action.
