Description of Event Types
MAX-700 353
Merged Event
All Event Types Are Tested
In the first case, where all event types are tested, the pass/fail conditions
are as follows:
If the event loss is less than or equal to the smallest threshold value,
then the event status is Pass.
If the event loss is greater than the sum of the number of sub-events of
a type, multiplied by the threshold value for this event type, then the
event status is Fail.
If the event loss is “in between”, since it is not possible to know exactly
the weight of a sub-event in the merged event, the global event is
considered to have a status of Pass.
If the merged event loss is smaller than or equal to 1.2, then the status is
Pass. Otherwise, it is Fail.
