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, correct the problem that caused 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, correct the problem
that caused 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). Each type
has unique characteristics and must be optimized accordingly.
For more information on the differences in site types,
please refer to the applicable BTS/Modem Frame Hardware
Installation and Functional Hardware Description
manuals.
NOTE
Cell Site Data File (CDF)
The CDF contains information that defines the BTS and data used to
download files to the devices. A CDF file must be placed in the
applicable BTS folder before the LMF can be used to log into that BTS.
CDF 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.
The CDF includes the following information:
 Download instructions and protocol
 Site specific equipage information
 C–CCP shelf allocation plan
– BBX2 equipage (based on cell–site type) including redundancy
– CSM equipage including redundancy
– Multi Channel Card (MCC24 or MCC8E) channel element
allocation plan. This plan indicates how the C–CCP shelf is
configured, and how the paging, synchronization, traffic, and access
channel elements (and associated gain values) are assigned among
the (up to 12) MCC24s or MCC8Es in the shelf.
