Preliminary Operations: Overview
Introduction
This section first verifies proper frame equipage against the site-specific
documentation supplied for each BTS application. This includes
verifying module placement, jumper, and dual in–line package (DIP)
switch settings. Next, pre-power up and initial power-up procedures are
presented. Finally, power–down and normal power–up procedures are
covered.
Cell–site Types
Sites are configured as omni or up to 3–sectors – one or two carriers.
Each type has unique characteristics and must be optimized accordingly.
CDF/NECF
The Configuration Data File (CDF) or Network Element Configuration
File (NECF) contains site type and equipage data information and passes
it directly to the LMF during optimization. The number of modem
frames, number and types of BBX and MCC boards, and linear power
amplifier assignments are some of the equipage data included in the
CDF/NECF.
NOTE
Be sure that the correct bts–#.cdf (or bts–#.necf) and cbsc–#.cdf
files are used for the BTS. These should be the CDF/NECF files
that are provided for the BTS by the CBSC. Failure to use the
correct CDF/NECF files can cause system errors. Failure to use
the correct CDF/NECF files to log into a live (traffic
carrying) site can shut down the site.
Site Equipage Verification
Review the site documentation. Match the site engineering equipage data
to the actual boards and modules shipped to the site. Physically inspect
and verify the equipment provided for the frame.
CAUTION
Always wear an approved anti–static wrist strap while handling
any circuit card/module to prevent damage by ESD. After
removal, the card/module should be placed on a conductive
surface or back into the anti–static packaging in which it was
shipped.
