1. A loop-structured communication system comprising:
- a main loop and an auxiliary loop parallel to each other each capable of circulating data signals in one of two possible directions opposite to each other;
a plurality of switchover units each connected at various positions in said loops for subdividing said loops into a plurality of loop sections;
a loop controller connected to said loops for controlling the data flow circulating in said loops;
delay means present in each of said switchover units for synchronizing the data flow between said main loop and said auxiliary loop when one or more of said loop sections is disconnected from the remainder of said loops.

Abstract
This is a communication loop system having a bidirectional transmission capability between terminals. The system is comprised of switching units which allow isolation of a loop segment and the establishment of an operable folded loop for the remaining non-isolated loop portions of the system. In addition, the communication loop system comprises devices for enabling synchronous switchover operation during reconfiguration of the loop. This synchronous switchover insures that no data stream interruption or disturbance occurs for the units or terminals not attached to the disconnected loop segment.
