Prerequisites
Before running this test, the following should be done:
 The card in slot CSM 1, GLIs, BBXs have correct code load.
 Primary CSM and MGLI are INS_ACT (bright green).
 All BBXs are OOS_RAM (yellow).
 Test equipment and test cables are calibrated and connected for TX
BLO calibration.
 LMF is logged into the BTS.
After a TX calibration has been performed using the procedure in
Table 3-41, or if verification of BLO data in the CAL file is required,
follow the procedure in Table 3-43 to perform a BTS TX path audit.
Table 3-43: TX Path Audit
Step Action
1 If it has not already been done, configure test equipment for TX path audit by following the procedure
in Table 3-38 (TX audit uses the same configuration as TX calibration).
2 Select the BBX(s) to be audited.
3 If the Test Pattern to be used is Standard, CDFPilot, or CDF, select at least one MCC (refer to “Test
Pattern Drop-down Pick List” under “TX Calibraton and the LMF” in this section).

NOTE
If necessary, the correct channel number may be manually entered into the Carrier # Channels box.
7 If at least one MCC was selected in Step 3, select the appropriate transfer rate (1 = 9600, 3 = 9600 1X)
from the drop-down list in the Rate Set box.
NOTE
The rate selection of 3 is only available if 1X cards are selected for the test.
