DRAFT

Introduction

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.

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

After a BTS is physically installed and the preliminary operations

(power up) have been completed, the LMF is used to calibrate and

optimize the BTS. Motorola recommends that the optimization be

accomplished as follows:

1. Download MGLI2–1 with code and data and then enable MGLI2–1.

2. Use the status function and verify that all of the installed devices of

the following types respond with status information: CSM, BBX,

GLI2, 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 the LMF.

3. Download code and data to all devices of the following types:

– CSM

– BBX (may be BBX2 or BBX–1X)

– GLI2 (other than MGLI2–1)

– 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 signals.

6. Enable the following devices (in the order listed):

– Secondary CSM

– Primary CSM

– All MCCs

7. Connect the required test equipment for a full optimization.

8. Select the test equipment.

9. 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.
