Version 7.2 301 Mediant 1000B Gateway & E-SBC
User's Manual 16. Quality of Experience
Parameter Description
 [2] Medium = (Default) Pre-configured medium sensitivity
threshold values.
 [3] High = Pre-configured high sensitivity threshold values.
Thus, reporting is done for small fluctuations in parameter
values.
Thresholds
Minor Threshold (Yellow)
minor-threshold-yellow
[QOEColorRules_MinorThreshold]
Defines the Minor threshold value, which is the lower threshold
located between the Yellow and Green states. To consider a
threshold crossing:
 Increase in severity (i.e., Green to Yellow): Only this value
is used.
 Decrease in severity (Red to Green, or Yellow to Green):
This value is used with the hysteresis, configured by the
'Minor Hysteresis (Yellow)' parameter (see below).
The valid threshold values are as follows:
 MOS values are in multiples of 10. For example, to denote a
MOS of 3.2, the value 32 (i.e., 3.2*10) must be entered.
 Delay values are in msec.
 Packet Loss values are in percentage (%).
 Jitter is in msec.
 Echo measures the Residual Echo Return Loss (RERL) in
dB.
Minor Hysteresis (Yellow)
minor-hysteresis-yellow
[QOEColorRules_MinorHysteresis]
Defines the amount of fluctuation (hysteresis) from the Minor
threshold, configured by the 'Minor Threshold (Yellow)'
parameter in order for the threshold to be considered as
crossed. The hysteresis is used only to determine threshold
crossings to Green (i.e., from Yellow to Green, or Red to
Green). In other words, the device considers a threshold
crossing to Green only if the measured voice metric crosses the
Minor threshold and the hysteresis.
For example, if you configure the 'Minor Threshold (Yellow)'
parameter to 4 and the 'Minor Hysteresis (Yellow)' parameter to
0.1 (for MOS), the device considers a threshold crossing to
Green only if the MOS crosses 4.1 (i.e., 4 + 0.1).
Major Threshold (Red)
major-threshold-red
[QOEColorRules_MajorThreshold]
Defines the Major threshold value, which is the upper threshold
located between the Yellow and Red states. To consider a
threshold crossing:
 Increase in severity (i.e., Yellow to Red): Only this value is
used.
 Decrease in severity (Red to Yellow): This value is used
with the hysteresis, configured by the 'Major Hysteresis
(Red)' parameter (see below).
The valid threshold values are as follows:
 MOS values are in multiples of 10. For example, to denote a
MOS of 3.2, the value 32 (i.e., 3.2*10) must be entered.
 Delay values are in msec.
 Packet Loss values are in percentage (%).
 Jitter is in msec.
