Preliminary Operations: Overview
Introduction
This section first verifies proper frame equipage. This includes verifying
module placement, jumper, and dual in–line package (DIP) switch
settings against the site-specific documentation supplied for each BTS
application. Next, pre-power up and initial power-up procedures are
presented.
Cell Site Types
Sites are configured as Omni, 3–sectored with a maximum of 4 carriers,
and 6–sectored with a maximum of 2 carriers. Each type has unique
characteristics and must be optimized accordingly. For more information
on the differences in site types, please refer to the BTS/Modem Frame
Hardware Installation manual.
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, C–CCP shelves, BBX boards, MCC boards (per cage), 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 BTS or Modem frame and
ancillary equipment frame.
CAUTION
Always wear a conductive, high impedance 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 shipping bag.
