ABSTRACT:
In an order wire communication control method in a bidirectional line-switched ring network system, two line terminalends located at both sides of faulty location transmit failure occurrence information utilizing APS bytes of APS protocol to other line terminalend in response to occurrence of failure in an order wire communication path on the ring network. The line terminalend where the order wire is terminated is released from termination in response to reception of the failure occurrence information of the APS bytes. Then, one of two line terminalends at both sides of the faulty location, commands termination of the order wire for the line repeater located closest to the faulty location among a plurality of line repeaters under control thereof. Thus, after release from failure, terminating control of the order wire becomes unnecessary to make it possible for all of the line terminalend to perform order wire communication.
