Threshold types
There are two types of thresholds:
• Threshold Report (TR): This value causes a threshold crossing event. When this
maximum is reached, the system raises the associated alarm if the prerequisite have
been applied (see Prerequisite to get an Alarm). The minimum value for TR is 1
(one).
• Reset Treshold Report (RTR): This value causes a resetting of the event. When this
threshold is reached, RTR clears the associated alarm. The RTR value is usually
lower than the RT value. The minimum value for RTR is 0 (zero).
Both thresholds are independently provisionable per termination point and
accumulation period for a given performance monitoring parameter.
Where X = TR and Y = RTR
If Then
Nb BBE > or equal to X System launches the associated alarm
X > or equal to Nb BBE > or equal to Y System stops the associated alarm
Threshold Range and Maximum
Each measurement parameter has a range for the acceptable values for TR. The lower
limit for this threshold can never be zero to avoid an alarm storm from the NE to the
ITM CIT.
The maximum allowable TR is dependent on:
• the parameter being measured;
• where performance is measured (meaning the TP);
• and the binning period.
The maximum threshold values for each parameters is listed in below:
