+      STATUS current

+      DESCRIPTION

+        "Active alarm table

+        

+        The device shall maintain this table, to maintain all outstanding 

+        (not cleared) alarms generated by the device, including:

+        1. Not hit device local alarm filter. That means had been reported to

+           trap receiver (NMS or EMS)

+        2. Hit local alarm filter. That means not trap is reported to trap receiver

+           for the alarm.

+        

+        The device shall maintain two numbers:

+        1. Alarm sequence number: As described in eponTrapSequenceNumber, it is initially

+           set to 1 when device restarts, increases per trap reported to trap receiver,

+           and rollover to 1 once it reaches the maximum value. 

+           From NMS's view, traps received from a nodes will be consecutive, by identifying 

+           the alarm sequence number carried in alarm trap. If breaks, means some trap 

+           may be lost, since packet loss between NMS and NE. 

+        2. Alarm raising number: This is maintained by NE internally and does not intend for

+           being acknowledged by external manage system. It is designed to uniquely indentify

+           each alarm raised by NE, excluding duplicates. Once one alarm raised, despite 

+           whether it is hit by alarm filter, NE shall assign a raising number to it. So, it

+           major functionality is to uniquely identify alarms hit NE local alarm filter, since 

+           this kindly alarm will not be reported to NMS, and hence no alarm sequence number

+           is assigned to it.

+           It is initially  set to 1 when device restarts, increases per alarm generation (

+           excluding duplicates), and rollover to 1 once it reaches the maximum value. 

+        

+        FUNCTION DESCRIPTION OF ACTIVE ALARM TABLE:         

+        ALARM RAISING

+        ----------------------        

+        1. When NE detects one fault and associates to one kind of alarm, it shall check whether

+           there is same alarm in active alarm table, which is indexed by alarm code and alarm

+           instance. If hits, it means duplicates, update the corresponding entry of the table.

+           Otherwise,

+        2. The alarm is not a duplicate. Assign an alarm raising number. Check whether the

+ alarm hits local alarm filters. If hits, set alarm sequence number to 0.

+           Create an entry into active alarm table. Otherwise,

+        3. Assign an alarm sequence number to the alarm. Create an entry into active alarm

+ table. Report the alarm trap to all trap receivers.

+           

+        ALARM CLEARING

+        ----------------------        

+        1. When NE detects one fault is cleared and associates to one kind of alarm, it shall 

+           check whether there is corresponding alarm in active alarm table, which is indexed

+by alarm code and alarm instance. If no hit, escape this clear event. Upon a hit,

+if the alarm sequence number is 0, move the active alarm entry to history alarm

+table and update the corresponding fields. At this case, historyAlarmCorrelationId

+and historyAlarmSeqNum will be set to 0.

+           Otherwise,

+        2. Assign an alarm sequence number to the clear trap. Report the alarm clear trap to 

+           all trap receivers. Move the active alarm entry to history alarm table and update 

+           the corresponding fields. At this case, activeAlarmSeqNum shall be copied to 

+           historyAlarmCorrelationId, and historyAlarmSeqNum shall be set to the new alarm

+           sequence number for the clear trap.

+        

+        ALARM SYNCHRONIZATION BETWEEN NE AND NMS

+        ---------------------------------------------        

+        1. Once NMS finds the alarm sequence number in reported alarm traps is not continuous,

+           it will walk active or history alarm table of the NE for the lost seuqence number.
