5.4.3 Set Uplink Gain
It may be necessary to adjust the Uplink gain of the mBSC-C system in order to achieve a balanced forward
and reverse link, or to adjust for other conditions (antenna placement, dynamic range requirements,
propagation characteristics at different bands, specific RF design). The MBSC1900-040-RU provides two
points of adjustment for uplink gain:
1. Software controlled attenuator for each band in the BIU
2. Software controlled attenuator in each band-specific Remote Unit
