S The calibration data for a BBX is organized as a large flat array. The
array is organized by branch, sector, and calibration point.
– The first breakdown of the array indicates which branch the
contained calibration points are for. The array covers transmit, main
receive and diversity receive offsets as follows:
Table 3-33: BLO BTS.cal File Array Assignments
Range Assignment
C[1]–C[240] Transmit
C[241]–C[480] Main Receive
C[481]–C[720] Diversity Receive
NOTE
Slot 385 is the BLO for the RFDS.
– The second breakdown of the array is per sector. Configurations
supported are Omni, 3–sector or 6–sector.
