Introduction to Optimization and Calibration
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, using
the RFDS, and verifying the customer defined alarms and relay contacts
are functioning properly.
NOTE
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 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. Companion frames must be optimized individually as separate
BTSs. The basic optimization process consists of the following:
1. Download MGLI (GLI–bts#–1) with application code and data and
then enable MGLI.
NOTE GLIs may be GLI2s or GLI3s.
2. Use the LMF status function and verify that all of the installed
devices of the following types respond with status information:
CSM, BBX, GLI, MCC8, and, if RFDS is installed, TSU or
RFDS–1X RPROC. 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 LMF.
3. Download device application code and data to all devices of the
following types:
– CSM
– BBX
– Remaining GLI (GLI–bts#–2)
– MCC
4. Download the RFDS TSIC or RFDS–1X RPROC (if installed).
5. Verify the operation of the GPS and HSO signals.
6. Enable the following devices (in the order listed):
– Secondary CSM (slot CSM 2)
– Primary CSM (slot CSM 1)
– All MCCs
7. Using the LMF test equipment selection function, select the test
equipment to be used for the calibration.
8. Calibrate the TX and RX test cables if they have not previously been
calibrated with the LMF computer and software build which will be
used for the optimization/calibration. Cable calibration values can be
entered manually, if required.
