Download BLO Procedure
After a successful TX path calibration, download the bay level offset
(BLO) calibration file data to the BBX2s. BLO data is extracted from the
CAL file for the Base Transceiver Subsystem (BTS) and downloaded to
the selected BBX2 devices.
If a successful All Cal/Audit was completed, this
procedure does not need to be performed, as BLO is
downloaded as part of the All Cal/Audit.
NOTE
Prerequisites
Ensure the following prerequisites have been met before proceeding.
S BBXs being downloaded are OOS–RAM (yellow).
S TX calibration successfully completed
After a TX calibration has been performed using the procedure in

the BBX2s.
