calibration, BLO download, TX audit, all TX tests, and all RX tests
for all selected devices.
If the TX calibration fails, repeat the full optimization for any failed
paths.
If the TX calibration fails again, troubleshoot and correct the problem
causing the failure, and repeat the full optimization for the failed path.
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.
Configuration Data File (CDF)
NOTE
Before using the LMF for optimization/ATP, the correct
bts-#.cdf and cbsc-#.cdf files for the BTS must be obtained
from the CBSC and put in a bts-# folder in the LMF. Failure to
use the correct CDF files can cause unreliable or improper site
operation.
The Configuration Data File (CDF), also called the Cell-site Data File,
includes the following information:
Download instructions and protocol
Site specific equipage information
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.
Effective Rated Power (ERP) table for all TX channels to antennas
respectively. Motorola System Engineering specifies the ERP of a
transmit antenna based on site geography, antenna placement, and
government regulations. Working from this ERP requirement, antenna
gain and antenna feed line loss can be combined to calculate the
required transmit power at the frame antenna connections. The
corresponding BBX output power required to achieve that power level
on any channel/sector can then be determined based on Bay Level
Offset (BLO) data established during the optimization process.
