Thresholds

7.26.7.1. Output Level Threshold (1, 2, 3)
The Gain Level Threshold control is used for real time monitoring and SNMP trap alarming. By defining
the output level, the IntelliGain system will send an SNMP alarm to VistaLINK® if the output loudness
level exceeds the defined output level. For example, by setting this control to –18 dBFS, if the calculated
output loudness level exceeds –18 dBFS (for the specified fault duration) then an alarm will be sent to
VistaLINK® for immediate operator notification. There are 3 levels of alarm thresholds. These can be
setup as minor, major and critical alarming thresholds. The Gain Level Threshold has a range of -65
dBFS to -1 dBFS.
7.26.7.2. Fault Duration
The Fault Duration control defines the amount of time that the IntelliGain system detects the output level
has been exceeded. For example, if this control is set to 25 seconds; this means that the output level has
to be exceeded for a minimum of 25 seconds before an SNMP trap alarm is sent to VistaLINK
Fault Duration has a range of 0.5 sec to 240 seconds.
7.26.7.3. Clear Duration Control
The Clear Duration defines the amount of time that the IntelliGain system must be corrected to before a
correction SNMP trap is sent to VistaLINK
that the IntelliGain output level fault must be corrected for a minimum of 10 seconds before a correction
alarm is sent to VistaLINK
wide dynamic range. The Clear Duration has a range of 0.5 sec to 240 seconds.
