 Downlink: Allows the user to manually adjust the DL attenuation levels for each RF path. Adjusting
these settings is not recommended since it will change the power ratios set by the user.
 Uplink: Allows the user to manually adjust the UL attenuation levels for each RF path. Adjusting these
settings is not recommended, unless additional attenuation is needed on the UL path.
 DL Output ALC Level: Allows the user to manually set the DL Output ALC Levels for each RF path.
Adjusting these settings is not recommended since it will change the power ratios set by the user.
These settings are automatically set by the system during the BCU commissioning process. This
section also displays the composite DL Output ALC Level which is the value that can be used to
commission the RFU.
