Summary0000427: Need to understand TR157 alarm notification to ACS.
DescriptionAccording to TR157 specs, Page 62
https://www.broadband-forum.org/download/TR-157.pdf#page=62&zoom=100,92,632
Expediate event will send immediately to ACS when any new expediate event/alarm is raised in CPE.

Currently we are using FM DB as CSV file. The expedited event will be look like below
When one expedite event is available the DB, it will have ExpeditedEventNumberOfEntries = 1 and its list with index = 0
    Device.FaultMgmt.{0}.ExpeditedEventNumberOfEntries,1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.EventTime,2021-03-23T14:24:53
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.AlarmIdentifier,AlarmIdentifier1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.NotificationType,NewAlarm
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.ManagedObjectInstance,ManagedObjectInstance1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.EventType,EventType1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.ProbableCause,ProbableCause1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.SpecificProblem,SpecificProblem1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.PerceivedSeverity,Minor
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.AdditionalText,AdditionalText1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.AdditionalInformation,AdditionalInformation1

 

When a new expeditate event is generated, then ExpeditedEventNumberOfEntries will be 2 and it will add a new list with index = 1, then DB will be look like below
    Device.FaultMgmt.{0}.ExpeditedEventNumberOfEntries,2
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.EventTime,2021-03-23T14:24:53
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.AlarmIdentifier,AlarmIdentifier1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.NotificationType,NewAlarm
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.ManagedObjectInstance,MOI1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.EventType,EventType1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.ProbableCause,ProbableCause1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.SpecificProblem,SpecificProblem1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.PerceivedSeverity,Minor
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.AdditionalText,AdditionalText1
    Device.FaultMgmt.{0}.ExpeditedEvent.{0}.AdditionalInformation,AdditionalInformation1
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.EventTime,2021-03-23T14:24:53
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.AlarmIdentifier,AlarmIdentifier2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.NotificationType,NewAlarm
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.ManagedObjectInstance,MOI2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.EventType,EventType2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.ProbableCause,ProbableCause2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.SpecificProblem,SpecificProblem2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.PerceivedSeverity,Minor
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.AdditionalText,AdditionalText2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.AdditionalInformation,AdditionalInformation2
    
So, in this case, when a new expedited alarm will generate, then we are expecting cwmp(4 VALUE CHANGE) will send ExpeditedEventNumberOfEntries and list of expedited event with index = 1 to ACS like below

    Device.FaultMgmt.{0}.ExpeditedEventNumberOfEntries,2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.EventTime,2021-03-23T14:24:53
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.AlarmIdentifier,AlarmIdentifier2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.NotificationType,NewAlarm
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.ManagedObjectInstance,MOI2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.EventType,EventType2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.ProbableCause,ProbableCause2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.SpecificProblem,SpecificProblem2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.PerceivedSeverity,Minor
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.AdditionalText,AdditionalText2
    Device.FaultMgmt.{0}.ExpeditedEvent.{1}.AdditionalInformation,AdditionalInformation2

 
Please let me know, how can we achieve this as per the specs.
