n ActionStep
11 Use the LMF Status Function to verify that all of the CSM Cards, BBX Cards, GLI Cards, and
MCC Cards respond with Device Status information.
– If an RFDS is installed, verify that the TSU or RFDS–1X RPROC responds.
NOTE
If a device is installed and powered up, but is not responding and is colored GRAY in the LMF
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.
12 Verify that the GPS and HSO are operational.
13 Using the LMF Selection Function, select the Test Equipment that is to be used for the
Calibration.
14 Calibrate the TX and RX Test Cables, if they have not previously been calibrated with the LMF
Computer and Software Build that will be used for the Optimization/Calibration.
– Cable Calibration Values can be entered manually, if required.
15 Connect the required Test Equipment needed for a Full Optimization.
16 Select all of the BBX Cards and all of the MCC Cards.
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.
S If the TX Calibration fails, repeat the Full Optimization for any failed paths.
S If the TX Calibration fails again, troubleshoot and correct the problem causing the failure, and
repeat the Full Optimization for the failed path.
S 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.
For more information on the different Site Types, please
refer to the applicable Hardware Installation Manual.
