Issue Description
No actual service runs on a tributary board of the OSN 3500 equipment, but the channels configured with service often report T_ALOS and other invalid alarms so that the alarm indicator light is on. The customer sometime hopes to eliminate the display of the alarm indicator light.
Handling Process
It is verified that:
1. For the NG-SDH equipment in versions earlier than V1R7, the alarm indicator light on a board is off only after alarms are cleared and is still on even if the alarms are suppressed.
2. For the NG-SDH equipment in V1R7 or later versions, the alarm indicator light on a board is off after alarms are suppressed.
Suggestions
If you hope to turn off an alarm indicator light during maintenance, refer to this case.
