Scenario 1 – too many alarms

3G Network with 40.000 alarms/day

Small operational staff

Hard to distinguish between important problems and noise

Scenario 1 - FMX Solution

FMX Filter and correlation rules

Process 86% of all alarms

Filter out 67% of total alarm flow

Alarm log analysisEstimated Alarm Reduction


With the WRX rules package, an estimated 87% and 53% of total alarm flow reduction may be achieved on

Coruña-OSS and Leganés-OSS respectively

The reduction level in the table is based on 5 minutes filtering for short lived alarms


Slide title 40 pt


Text 24 pt



Alarm log analysisRules on Demand


By using simple short-lived filtering, a further 4% and 11% of total alarm flow reduction may be achieved on Coruña-OSS and Leganés-OSS .

The focus would be on the IMA alarms group:– IMA Link Transmit Unusable at Far End– IMA Group Insufficient Links at Far End– IMA Link Reception Unusable at Far End– IMA Group Insufficient Links– Remote Defect Indication on IMA Link– IMA Group Configuration Aborted
