Introduction to Optimization & Calibration

5/21/04 1X SC4812T–MC BTS Optimization/ATP 3-1

DRAFT

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, 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.

NOTE

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.

GLIs may be GLI2s or GLI3s.

NOTE

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

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

GLI, 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 or NEC files. The CDF or NEC files 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 (multicarrier uses BBX–1X)

– GLI (other than MGLI–1)

– MCC (may be MCC–8E, MCC24, or MCC–1X)

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

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

– Secondary CSM

– Primary CSM

– All MCCs

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

7. Select the test equipment.
