system Alarm Level Change Counter

1.3.6.1.4.1.9.10.26.1.1.3

Counter indicating a change in the system alarm level due to change either at the slot or port alarm level. This will be incremented by the system whenever any new alarm is raised or cleared at slot or port level. This is needed as rising or clearing of an alarm at port or slot level may not cause systemAlarmLevel to change. This counter, in such case helps manager application to recognize that alarm levels below system level has changed without causing change in the systemAlarmLevel. e.g. Say: System has two subscriber lines experiencing a minor alarm condition. systemAlarmLevel will be a minor alarm in such case. Now if one of the port level minor alarms clear, a port alarm level would become OK but the system and slot alarm levels may stay as a minor alarm.
