Introduction
This chapter provides procedures for downloading system operating
software, set up of the supported test equipment, CSM reference
verification/optimization, and transmit/receive path verification.
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
After a BTS is physically installed and the preliminary operations
(power up) have been completed, the CDMA LMF is used to calibrate
and optimize the BTS. The basic optimization process can be
accomplished as follows:
S Download MGLI2–1 with code and data and then enable MGLI2–1.
S Use the status function and verify that all of the installed devices of
the following types respond with status information: CSM2, BBX2,
GLI2, and 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 file. The CDF file
will have to be corrected before the device can be accessed by CDMA
LMF.
S Download code and data to all devices of the following types:
– CSM2
– BBX2
– GLI2 (other than MGLI2–1)
– MCC
S Download the RFDS TSIC (if installed).
S Verify the operation of the GPS and HSO signals.
S Enable the following devices (in the order listed):
– Secondary CSM (slot 2)
– Primary CSM (slot 1)
– All MCCs
S Connect the required test equipment for a full optimization.
S Select the test equipment.
S Calibrate the TX and RX test cables if they have not previously been
calibrated using the CDMA LMF that is going to be used for the
optimization/calibration. The cable calibration values can also be
entered manually.
S Select all of the BBXs and all of the MCCs and use the full
optimization function. The full optimization function performs TX
