Prerequisites

Before running this procedure, be sure that the following have been

done:

S The card in slot CSA, GLI, MCCs, and BBXs have correct code and

data loads.

S All BBXs are OOS_RAM (yellow).

S If running calibration or audit using a test pattern other than Pilot,

MCCs are INS_ACT (bright green).

S Test equipment and test cables are calibrated and connected for TX

calibration.

S LMF is logged into the BTS in the GUI environment.

Verify all BBX cards removed and repositioned have been

returned to their assigned shelves/slots. Any BBX cards

moved since they were downloaded will have to be

downloaded again.

NOTE

Follow the procedure in Table 6-35 to perform BLO calibration on the

TX paths, download BLO values to the BBXs, and perform TX path

audit in one operation.
