public class Mtp2AlarmEvent

extends OamAlarmEvent

A Mtp2AlarmEvent is an Event emitted by a Mtp2 Managed Object(MO) to indicate a change in status of the MO. This state change may result from :

• a create/delete/modify operation by an application that expliciltly changes the state of the MO.
• a change in the SS7 Network that implicitly changes the state of it's associated MO.
• a timer within a Timer MO expiring.

This Event should be sent to all applications that have registered with the Mtp2 Layer MO as a Mtp2 Alarm Listener.

Constructor Detail

Mtp2AlarmEvent

public Mtp2AlarmEvent(Mtp2ManagedObject source,
                      int priority,
                      int alarmType)

Constructs a new Mtp2AlarmEvent.

Parameters:

source - The Managed Object that emitted this Event.

priority - The priority of this Mtp2AlarmEvent. This may be either (in increasing order of priority):

1. PRIORITY_INFORMATIONAL - The cause of this event does not affect the functional state of the system and may be ignored.
   This Mtp2AlarmEvent is for purely informational purposes only.
2. PRIORITY_LOW - Indicates that the state of the MO that emitted this Mtp2AlarmEvent has changed as a result of an operation explicitly invoked by an application.
3. PRIORITY_HIGH - Indicates that the physical network element associated with the MO that emitted this Mtp2AlarmEvent has gone out of service.
   Without corrective action, service reliability can be severely affected.
4. PRIORITY_CRITICAL Indicates the complete failure of the physical netwrok element associated with the MO that emitted this Mtp2AlarmEvent. Immediate recovery action is required.

alarmType - The type of this alarm. This may be any one of the Alarm Type constants defined in this class, or one of those inherited from OamAlarmEvent.
