Site Equipage Verification
2-2
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.
Sites are configured as Omni with a maximum of 4 carriers, 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 1X SC 4812T-MC BTS Hardware Installation manual.
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.
CAUTION
Be sure that the correct bts–#.cdf 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.
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.
