9. Connect the required test equipment for a full optimization.
10. 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.
11. If the TX calibration fails, repeat the full optimization for any failed
paths.
12. If the TX calibration fails again, troubleshoot and correct the
problem causing the failure, and repeat the full optimization for the
failed path.
13. If the TX calibration and audit portion of the full optimization passes
for a path but some of the TX or RX tests fail, troubleshoot and
correct the problem causing the failure, and run the individual tests
as required until all TX and RX tests have passed for all paths.
Cell-site Types
Sites are configured as Omni/Omni or Sector/Sector (TX/RX).
Sector/Sector sites are the three–sector configuration. The SC4812ET
Lite does not support six–sector operation. Each cell site type has unique
characteristics and must be optimized accordingly.
NOTE
For more information on the different in site types, please refer
to the applicable Hardware Installation manual.
CDF/NECF
The CDF/NECF (Configuration Data File/Network Element
Configuration File) contains information that defines the BTS and data
used to download files to the devices. A CDF/NECF file must be placed
in the applicable BTS folder before the LMF can be used to log into that
BTS. CDF/NECF files are normally obtained from the CBSC using a
floppy disk. A file transfer protocol (ftp) method can be used if the LMF
computer has that capability. Refer to the LMF Help function on–line
documentation for more information.
The CDF/NECF includes the following information:
S Download instructions and protocol
S Site specific equipage information
S SCCP shelf allocation plan
– BBX equipage (based on cell–site type) including IS–95A/B or
CDMA2000 1X capability and redundancy
– CSM equipage including redundancy
– Multi Channel Card 24E, 8E, or –1X (MCC24E, MCC8E, or
MCC–1X) channel element allocation plan. This plan indicates how
the SCCP shelf is configured, and how the paging, synchronization,
traffic, and access channel elements (and associated gain values) are
assigned among the (up to 4) MCC24Es, MCC8Es, and/or
MCC–1Xs in the shelf.
S Effective Rated Power (ERP) table for all TX channels to antennas
respectively. Motorola System Engineering specifies the ERP of a
