Introduction to Optimization and Calibration

6-4 1X SC480 BTS Hardware Installation, Optimization/ATP, and FRU MAY 2004

PRELIMINARY

Overview

This section describes procedures for isolating the BTS from the span

lines, preparing and using the WinLMF, downloading system operating

software, CSA reference verification/optimization, set up and calibration

of the supported test equipment, and transmit/receive paths are

functioning properly.

Before using the WinLMF, use an editor to view the

“CAVEATS” section in the “readme.txt” file in the c:\wlmf

folder for any applicable information.

NOTE

Optimization Process

Summary

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

as power up, have been completed, the WinLMF is used to optimize the

BTS. The basic optimization process consists of the following:

1. Download GLI3 (GLI–bts#–1) with application code and data and

then enable GLI3.

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

devices of the following types respond with status information:

CSA, BBX, GLI3, and MCC. 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/NECF file must be

corrected before the device can be accessed by the WinLMF.

3. Download device application code and data to all devices of the

following types:

– CSA

– BBX–1X

– MCC–1X

4. Verify the operation of the GPS and HSO/MSO signals.

5. Using the WinLMF test equipment selection function, select the test

equipment to be used for the calibration.

6. Calibrate the TX and RX test cables if they have not previously been

calibrated with the WinLMF computer and software build which will

be used for the optimization/calibration. Cable calibration values can

be entered manually, if required.

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

8. 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.

9. If the TX calibration fails, repeat the full optimization for any failed

paths.
