shortlyafter08:45.Alldatapriortothattimebec omesinvalidated.Theonlyvaliditemsare
therecordingsfollowingthere‐sync.

8.4.2MoreontheThresholds
RSLThresholds
TwoRSLThresholdscanbedefined.Theyareusedasanindicatorofproblemsintheradio
channel.YoucanchecktheRSSfromtheLinkBudgetCalculatorresultsduringinstallation.
Valuesof‐5dBand‐8dBfromthecurrentRSSaretypical.
TSLThreshold
Acounterismaintained,ofthenumberofsecondintervalsduringwhichTxpowerexceeds
thisthreshold.
BBERThreshold
TheBackgroundBlockErrorRatioismeasuredasapercentage.Thethresholdcanbesetfrom
0.1%upto50%.
An8%thresholdisrecommended.Iftherearenoproblemsduringtheinterval,thenforthat
threshold,therecommendedBBERvalueshouldbe0.Sincethesystemprovidesalossless
Ethernetservice,thereisthroughputdegradationincaseofinterference.Thedegradationis
proportionaltotheBBER.
EthernetThresholds‐Capacity
ThisisusedasabasisforcheckingadherencetoaServiceLevelAgreement.Itisthenumber
ofsecondscountthatthelinkcapacityfallsbellowthethreshold.
EthernetThresholds‐Traffic
Thenumberofsecondscountthatreceivedtrafficexceededthisthreshold.Itcanbeusedto
measuretrafficpeaks.
