Title: Transmission line monitoring method
Inventor: HASHIMOTO YOICHI
IPC: H03M5/06
Filed: 1989-11-10
Abstract: PURPOSE:To recognize the content of a fault by detecting the state of a CMI code depending on the rise and fall of a clock pulse, separating the code rule violation from the separated signal and the clock pulse, integrating each code rule violation generated for the period of prescribed number of times of generating clock pulses and monitoring the fault of the transmission system. CONSTITUTION:A CMI code and a clock pulse outputted from a clock recovery circuit 4 are fed to an error detection circuit 5 and detects a code rule violation in which the CMI code is fixed to a high level or to a low level thereby outputting a signal. Counter circuits 6, 7 integrate LAL (Low-Level Alarm) or HAL (High-Level Alarm) for a prescribed period when a prescribed number (e.g. 100) of clock pulses is repeated, and detect the reduction in the optical output or the increase in the optical output when the integration value exceeds a prescribed value such as 2 and detect the disconnection of a line or collision when the integration value exceeds 10. Thus, a cause to a code rule error is recognized and the processing for restoration is implemented.
