        is required. Such a severity can be reported, for example, when a
        managed object becomes totally out of service and its capability needs
        to be restored (ITU-T Recommendation X.733).
      * MAJOR: The Major severity level indicates that a service affecting
        condition has developed and an urgent corrective action is required.
        Such a severity can be reported, for example, when there is a severe
        degradation in the capability of the managed object and its full
        capability needs to be restored (ITU-T Recommendation X.733).
      * MINOR: The Minor severity level indicates the existence of a
        non-service affecting fault condition and that corrective action
        should be taken in order to prevent a more serious (for example,
        service affecting) fault. Such a severity can be reported, for
        example, when the detected alarm condition is not currently degrading
        the capacity of the managed object (ITU-T Recommendation X.733).
      * WARNING: The Warning severity level indicates the detection of a
        potential or impending service affecting fault, before any significant
        effects have been felt. Action should be taken to further diagnose (if
        necessary) and correct the problem in order to prevent it from
        becoming a more serious service affecting fault (ITU-T Recommendation
        X.733).
      * INDETERMINATE: The Indeterminate severity level indicates that the
        severity level cannot be determined (ITU-T Recommendation X.733).
      * CLEARED: The Cleared severity level indicates the clearing of one or
        more previously reported alarms. This alarm clears all alarms for this
        managed object that have the same Alarm type, Probable cause and
        Specific problems (if given) (ITU-T Recommendation X.733).
