    Clearing a ContComS Alarm

    Note: Follow all applicable safety requirements as described in the BTI7800 Series Hardware Overview and Installation Guide.

    1. Check for and clear alarms on OSC entities at both the local and far-end NEs.
    2. Check the far-end NE for conditions indicating a module reset.
    3. Check for alarms on the local OSC.
      • If the alarm has cleared, you have completed this procedure.
      • If the alarm does not clear, contact your next level of support.
