摘要
PROBLEM TO BE SOLVED: To obtain a squelching method for ring transmission system which can be applied not only to a simple two-way communication circuit, but also to various types of communication circuits, such a plurality of source/drop/ simultaneous transmission, etc. SOLUTION: A method for definitely squelching communication circuit includes a step (506) of identifying a faulty node, a step (507) of identifying the communication circuit having an entrance/exit in the faulty node, steps (508, 509, and 510) of squelching an active communication circuit in a prescribed node when the adjacent first node of the prescribed node on the downstream side and the exit node of the communication circuit on the most downstream side of the prescribed node become faulty, and steps (510 and 512) of squelching the active communication circuit in the prescribed node when the squelching in the steps 508, 509, and 510 is not executed and the adjacent second node of the prescribed node on the upstream side and the entrance node of the communication circuit on the most upstream side of the prescribed node become faulty.
