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

The Cell–SiteData File (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

– BBX equipage (based on cell–site type) including redundancy

– CSM equipage including redundancy

– MCC (MCC24E, MCC8E, or MCC–1X) 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) MCCs in the shelf.
