DRAFT

8. Calibrate the TX and RX test cables if they have not previously been

calibrated using the CDMA LMF that will be used for the

optimization/calibration. The cable calibration values can also be

entered manually.

All PAs must be INS during any TX testing.

NOTE

9. If the TX calibration fails, repeat the optimization for any failed

paths.

10. If the TX calibration fails again, correct the problem that caused the

failure and repeat the optimization for the failed path.

11. If the TX calibration and audit portion of the 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, refer

to the applicable BTS Hardware Installation manual.

NOTE

Configuration Files

The Configuration Data File (CDF) and the Network Element

Configuration (NEC) files contain information that defines the BTS and

data used to download files to the devices. The BTS CDF (

bts–#.cdf)

and CBSC CDF (cbsc–#.cdf) files are used by circuit BTSs. The NEC

Base (NECB –

NECB*bts#.xml) and NEC Journaling (NECJ –

NECJ*bts#.xml) files are used by packet BTSs. CDF or NEC files

must be placed in the applicable BTS folder before the LMF can be used

to log into that BTS. CDF and NEC 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 and NEC files include the following information:

S Download instructions and protocol

S Site specific equipage information

S 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.
