Major:  service-affecting conditions that cause the loss of a single low 
speed line or cause performance issues on the high-speed line.

Minor:  conditions that do not affect service.

You can view alarms in two ways: Current Alarms or Alarm Log history. 
You can view the alarms for either the active card or the standby card.

The Current Alarms screen displays the date and time the alarm started, de-
tails about the alarm, the time remaining on the Alarm Cutoff (ACO) timer 
(if it has been engaged), and where you can engage and disengage the 
ACO. Engaging the ACO closes the external alarm contacts, turning them 
off, while disengaging the ACO turns external alarms back on.
