DRAFT
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 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.
CDF or NEC
The Configuration Data File (CDF) (circuit BTS) or Network Element
Configuration (NEC) files (packet BTS) 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 power amplifier assignments are some of the
equipage data included in the CDF or NEC files.
Be sure that the correct bts–#.cdf and cbsc–#.cdf or
NECB*bts#.xml and NECJ*bts#.xml files are used for
the BTS. These should be the CDF or NEC files that are
provided for the BTS by the OMC–R. Failure to use the
correct CDF or NEC files can cause system errors. Failure
to use the correct CDF or NEC files to log into a live
(traffic carrying) site can shut down the site.
CAUTION
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.
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.
