Dear friend!
Synchronize the alarm again. If the alarm persists, perform the following operations:
1. The line attenuation does not improve. Please optimize the line quality management again.
2. The alarm threshold is improperly set.Check whether the alarm threshold is too small. You can set a proper alarm threshold based on the live network plan.
3. The VOA setting is improper.Check whether there is an unconfigured VOA on the line. If yes, manually adjust the attenuation to the normal value.
4. The board may be damaged. Use a new board for comparison.If the board is faulty, replace the board.
Thank you!
