NOTE

Refer to Figure 3-1 and the LMF Help function on–line

documentation for additional information on the layout of the

LMF directory structure (including CDF/NECF file locations

and formats).

BTS System Software Download

BTS system software must be successfully downloaded to the BTS

processor boards before optimization can be performed. BTS operating

code is loaded from the LMF computer terminal.

BTSs configured for Circuit Backhaul use bts.cdf files. BTSs configured

for Packet Backhaul use bts.necf files (bts–xxx.xml) located on the

OMC/R.

NOTE

Before using the LMF for optimization/ATP, the correct

bts–#.cdf (or bts–#.necf) 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/NECF files can cause

wrong results. Failure to use the correct CDF/NECF files to

log into a live (traffic carrying) site can shut down the site.

The CDF/NECF is normally obtained from the CBSC on a DOS

formatted diskette, or through a file transfer protocol (ftp) if the LMF

computer has ftp capability. Refer to the LMF Help function on–line

documentation for the procedure.

Site Equipage Verification

If you have not already done so, use an editor to view the CDF/NECF,

and review the site documentation. Verify the site engineering equipage

data in the CDF/NECF matches the actual site hardware using a

CDF/NECF conversion table.

CAUTION

– Use extreme care not to make any changes to the

CDF/NECF content while viewing the file. Changes to the

CDF/NECF can cause the site to operate unreliably or

render it incapable of operation.

– Always wear a conductive, high impedance wrist strap

while handling any circuit card/module to prevent damage

by ESD. Extreme care should be taken during the removal

and installation of any card/module. After removal, the

card/module should be placed on a conductive surface or

back into the anti–static bag in which it was shipped.
