Abstract
PURPOSE:To simplify the system constitution and to keep high reliability, by providing an optical switch section corresponding to each remote station and remote station status monitoring section in a center station. CONSTITUTION:A CS control section in a center station CS1 reads the operation state of each RS from a remote station RS status monitoring section 16, correspondingly optical switches OSW1-OSWn, 14a-14n corresponding to each RS are turned on and off via an optical switch control section 15 to complete the optical transmission loop. If transmission error is detected at a loop control section 12, a control section 11 checks the operation status change of each RS via the monitoring section 16 and disconnects a failed RS from the optical transmission line. The control section 11 turns off the OSW14a-14n, and after the execution of loop transmission in the CS, the loop transmission is made sequentially to each RS to discriminate the disconnected transmission line.
