A.C is the wavelength division OTM site, and B is the relay site. When the optical fiber in the sending direction from station A to station B is interrupted, the WDM side of the OTU relay board of station B will report the R_LOS emergency alarm and perform processing, and then send it to upstream A. OTU2_BDI minor alarm at the sub-side of the station. At the same time, the alarm continues to be transmitted to the downstream station of station B. After the alarm is processed at station C, the WDM side of the OTU board at station C will report the ODU2_PM_AIS minor alarm, and return the ODU2_PM_BDI minor alarm to the upstream station A.
