Cutoff
Amber Audible Alarm has sounded, alarm cutoff switch has
been pushed
Minor Alarm Amber Indicates a minor alarm has occurred, includes E1 or
T1 BPV or fiber sync slip.
Major Alarm RED Indicates a major alarm has occurred, includes E1,
T1, and fiber signal loss.
Far End Error Amber Indicates a far end (remote) error has occurred
