Clearing an MS-AIS Condition
Follow all applicable safety requirements as described in the BTI7800 Series Hardware Overview and Installation Guide.
- Check for and clear all alarms on the upstream NE.
- Check for conditions on the local interface.
If the condition clears, you have completed this procedure.
If the condition does not clear, contact your next level of support.
