You can modify threshold values for event detection using the Tools, Display Thresholds command. It is important to set your threshold before loading the data because it will affect the analysis, diagnosis and display of data in Spotlight. To modify the value, simply click on the associated number and type in the new value.

This threshold is used to filter out the display of data in the CDMA Dashboard that have percentage of rev link problems cases less than the threshold.
Recommended value is 2.
15.1.2.10 CDMA_MobileRxPowerThreshold
This threshold is used in conjunction with EcIo and Mobile Tx Power Thresholds to determine the diagnosis for the dropped call, failed call and voice call with poor quality. Recommended value is -80 dBm. Values should vary between -75 and - 90 dBm.
15.1.2.11 CDMA_MobileTxPowerMinFilterThreshold
This threshold is used in conjunction with Mobile Tx Power Max Threshold to filter out messages when the transmitter is disabled due to high FFER. Default is -30. 15.1.2.12 CDMA_MobileTxPowerMaxFilterThreshold
This threshold is used in conjunction with Mobile Tx Power Min Threshold to filter out messages when the transmitter is disabled due to high FFER. Default is 23. 15.1.2.13 CDMA_MobileTxPowerThreshold
This threshold is used in conjunction with EcIo and Mobile Rx Power Thresholds to determine the diagnosis for the dropped call, failed call and voice call with poor quality. Recommended value is 5 dBm. Values should lie between 0 and 10 dBm. 15.1.2.14 CDMA_PilotPollution_Count_Threshold
This is the absolute number of pilots (with Ec/Ios above
CDMA_PilotPollutionThreshold) required to trigger a pilot pollution event. The recommended value is 3 and values should lie between 2 and 4.
15.1.2.15 CDMA_PilotPollutionThreshold
This threshold alerts the user of pilot pollution when the signal level falls below this threshold. Recommended value is -14 dB. Values should lie between -10 and -18 dB.

15.1.3 CDMA / Events
15.1.3.1 EVT_CDMAImportantIssue
1 = Turns on the CDMA Important Issue Detect event diagram for CDMA
Troubleshooter; 0 = CDMA Important Issue analysis is turned off to improve file load speeds. Default is 0.
15.1.3.2 EVT_CDMANeighborListIssueDetect
1 = Turns on the CDMA Neighbor List Issue Detect event diagram for CDMA Troubleshooter; 0= CDMA Neighbor List Issue Detect analysis is turned off. Default is 0.
15.1.3.3 EVT_CDMAServerKey
1 = Turns on the CDMA Server Key event diagram for CDMA Troubleshooter; 0 = CDMA Server Key analysis is turned off to improve file load speeds. Default is 0.
15.1.3.4 UniqueNeighborList
1 = Turns on the unique neighbor list analysis for CDMA, EVDO Troubleshooter; 0 = unique neighbor list analysis is turned off to improve file load speeds. Default is 0.
15.1.4 CDMA / Other
15.1.4.1 CDMA_EcIoInterferenceThreshold
Recommended value is -15 dBm. The maximum should not be higher than 0 and minimum should not be lower than -25 dBm.
15.1.4.2 CDMA_EVDO_TooManyActivePNsThreshold
In calculating "Too Many Servers", when 4 or more pilots (including the best server) are within the threshold value in dB of the best server, it creates a "too many server" event. Recommended value is 5 dB and the minimum and the maximum should be around 1 and 10 dB.
15.1.4.3 CDMA_TooManyActivePNsThreshold
In calculating "Too Many Servers", when 4 or more pilots (including the best server) are within the threshold value in dB of the best server, it creates a "too many server" event. Recommended value is 5 dB and the minimum and the maximum should be around 1 and 10 dB.
15.1.5 CDMA / Performance
15.1.5.1 CDMA_CallDropRate
This threshold is used to determine the criterion for KPI acceptance in the
Repository views. The Call Drop Rate should not exceed 2% of all successful calls in the busy hour. If the resulting KPI is equal or less than this value, it will be flagged as accepted and will show up as a green tick mark in the KPI table. If it is higher than this value, it will be flagged as failed and will show up as a red cross in the KPI table. The default value is 2%.
2
15.1.5.2 CDMA_CallSetupSuccessRate
This threshold is used to determine the criterion for KPI acceptance in the Repository views. The Call Setup Success Rate should be in excess of 98% for most GSM networks in the busy hour. If the resulting KPI is equal or in excess to this value, it will be flagged as accepted and will show up as a green tick mark in the KPI table. If it is less than this value, it will be flagged as failed and will show up as a red cross in the KPI table. The default value is 98%.
15.1.5.3 CDMA_CallSetupTime
This threshold is used for determining calls with excessive setup time. Recommended value is 2000 ms.
15.1.5.4 CDMA_OverAllSuccessRate
This threshold is used to determine the criterion for KPI acceptance in the
Repository views. The Overall Success Rate should be in excess of 98% for most GSM networks in the busy hour. If the resulting KPI is equal or in excess to this value, it will be flagged as accepted and will show up as a green tick mark in the KPI table. If it is less than this value, it will be flagged as failed and will show up as a red cross in the KPI table. The default value is 98%.
