Bay Level Offset Calibration – continued
3-122 1X SC 4812T Lite BTS Optimization/ATP FEB 2005
PRELIMINARY
At new site installations, to facilitate the complete test of
each SCCP Cage (if the cage is not already fully populated
with BBX Cards), move BBX Cards from shelves
currently not under test and install them into the empty
BBX Slots of the shelf currently being tested to insure that
all BBX TX Paths are tested.
– This procedure can be bypassed on operational sites
that are due for periodic Optimization.
– Prior to testing, view the CDF (or NECF) File to
verify that the correct BBX Slots are equipped. Edit
the file as required to include BBX Slots not currently
equipped (per Systems Engineering Documentation).
NOTE
All Cal/Audit and TX
Calibration Procedure
The LMF All Cal/Audit and TX Calibration Procedures are essentially
identical, except for the step that selects the type of procedure desired.
– Refer to Step 4 in Table 3-41.
Prerequisites
Before running this procedure, make sure that the following
actions/items have been performed/checked.
S The CSM Card in the CSM 1 Slot, GLI Cards, MCC Cards, and BBX
Cards have correct Code and Data Loads.
S The LEDs on the Primary CSM and MGLI Cards are INS_ACTIVE
(bright green).
S All BBX Cards are OOS_RAM (yellow).
S If running Calibration or Audit using a Test Pattern other than Pilot,
MCC Cards are INS_ACTIVE (bright green).
S Test Equipment and Test Cables are calibrated and connected for TX

downloaded need to be downloaded again.
NOTE
Perform the procedure in Table 3-41 to perform BLO Calibration on the
TX Paths, download BLO Values to the BBX Cards, and perform TX
Path Audit in one operation.
