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, correct the problem that caused 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, 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.

Cell Site Data File (CDF)

The CDF includes the following information:

S Download instructions and protocol

S Site specific equipage information

S C–CCP shelf allocation plan

– BBX2 equipage (based on cell–site type) including redundancy

– CSM equipage including redundancy

– Multi Channel Card 24 (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.

S CSM equipage including redundancy

S 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, the

antenna gain, (dependent on the units of measurement specified) and

antenna feed line loss can be combined to determine the required

power at the top of the BTS frame. The corresponding BBX2 output

level required to achieve that power level on any channel/sector can

also be determined.

for additional information on the layout of the LMF

directory structure (including CDF file locations and

formats).
