DlPowerDegradation alarm for baseband 3G sites E*******

Dear expert,

Could someone help me on the DlPowerDegradation issue please? I have done change in the 3G network. I have limitated the R99 admission in the network in purpose to save more ressources for HSDPA and CS RAB. Please find below the parameter changes.

- sf8Adm=0
- sf16Adm=0
- sf16gAdm=0
- sf32Adm=8
- sf128Adm=32
- rateSelectionPsInterctive.dlPrefrate=16
- pwrAdm=75
- pwrOffset=25
- schMinPowerNonGbrHsUsers=15
- dlCodeAdm=50
- maxRate=40690
- maxPwrMax=30
- minimumRate=370
- minPwrMax= -15
- interPwrMax=30
- interRate=845

After the action, the hsdpa user throughput increase but there is DLpower degradation for somes baseband 3G sites. I have already done the rollbak for the sites which have this issue but no change. the alarm still there even with restart of the node.

Could you please help? Thanks.
