MTP Alarm

-MTP alarm overview

-MTP state alarm

-MTP event alarm

 

1.MTP Alarm Overview 

 

-There are three kinds of MTP alarm:

-failure alarm

-recovery alarm

-event alarm

-The failure alarm and recovery alarm can be called a general name, state alarm, and state alarms are bi-directional.

-According to the relationship of MTP tables, MTP alarms often appear as following sequence:

-Link alarm<＝> link set alarm <＝> routing alarm <＝> destination SP alarm

 

2.MTP State Alarm 

-State alarm refers to the alarms generated when there are state changes in signaling link and signaling network of MTP module. 

        -For example：
      −Signaling link available-unavailable
      −Destination signaling point available-unavailable

 

3.MTP Event Alarm 

 

-Event alarm refers to report between independent events and they have no certain relation. -Since an event is always followed with some state changes, so an event alarm is always followed with one or some state alarms.
