• Define the Interface Type – RF Source interface type (i.e. CMA RIU, Other)
• If the DL Input power Low and DL Input power High alarms are RED, perform DL RF
adjustment:
o Low or High DL Input power indicates that the measured input power from
the BTS source is either lower or higher than the expected value:
• When connected to RIU: Up to -20dBm
• When connected directly to BTS (via passive interface): Up to 0dBm
o Adjust RF DL gain with Operational Att. (in 0-31 dB steps).
