PRELIMINARY

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.

IMPORTANT

Optimization Process Overview

After a BTS is physically installed and the preliminary operations, such

as power up, have been completed, the CDMA LMF is used to calibrate

and optimize the BTS. The basic optimization process consists of the

following:

S Download MGLI2 (GLI2–<bts#>–1) with application code and data

and then enable MGLI2.

S Use the CDMA LMF 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 device application code and data to all devices of the

following types:

– CSM2

– BBX2

– Remaining GLI2 (GLI2–<bts#>–2)

– 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 Using the CDMA LMF test equipment selection function, select the

test equipment to be used for the calibration.

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. Cable calibration values can be entered

manually, if required.

S Connect the required test equipment for a full optimization.
