Introduction to Optimization and Calibration
Overview
This section describes procedures for isolating the BTS from the span
lines, preparing and using the LMF, downloading system operating
software, CSM reference verification/optimization, set up and calibration
of the supported test equipment, transmit/receive path verification, using
the RFDS, and verifying the customer defined alarms and relay contacts
are functioning properly.
NOTE
Before using the LMF, use an editor to view the “CAVEATS”
section in the “readme.txt” file in the c:\wlmf folder for any
applicable information.
Optimization Process Summary
After a BTS is physically installed and the preliminary operations, such
as power up, have been completed, the LMF is used to optimize the
BTS. The basic optimization process consists of the following:
1. Download MGLI–1 with code and data and then enable MGLI–1.
NOTE GLIs may be GLI2s or GLI3s.
2. Use the status function and verify that all of the installed devices of
the following types respond with status information: CSM, BBX,
GLI, MCC, and TSU (if RFDS is installed). If a device is installed
and powered up but is not responding and is colored gray in the BTS
display, the device is not listed in the CDF/NECF file. The
CDF/NECF file must be corrected before the device can be accessed
by the LMF.
3. Download code and data to all devices of the following types:
– CSM
– BBX (may be BBX2 or BBX–1X)
– GLI (other than MGLI–1)
– MCC (may be MCC–8E, MCC24, or MCC–1X)
4. Download the RFDS TSIC (if installed).
5. Verify the operation of the GPS and HSO or LFR signals.
6. Enable the following devices (in the order listed):
– Secondary CSM
– Primary CSM
– All MCCs
7. Using the LMF test equipment selection function, select the test
equipment to be used for the calibration.
8. Calibrate the TX and RX test cables if they have not previously been
calibrated using the CDMA LMF that will be used for the
optimization/calibration. The cable calibration values can also be
entered manually.
9. Connect the required test equipment for a full optimization.
10. Select all of the BBXs and all of the MCCs, and use the full
optimization function. The full optimization function performs TX
calibration, BLO download, TX audit, all TX tests, and all RX tests
for all selected devices.
