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.
Circuit Backhaul BTS
The information below is for Circuit-Backhaul BTS. GLI-3’s
configured for Circuit-backhaul use bts.cdf files.
NOTE
Before using the LMF for optimization/ATP, the correct
bts-#.cdf 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 files can cause wrong results.
CAUTION
Failure to use the correct CDF files to log into a live (traffic
carrying) site can shut down the site.
Packet-Backhaul BTS
GLI-3’s are configured for Packet-backhaul BTS’s the file that is needed
to login to the BTS is the NECF file (bts-xxx.xml) located on the
OMC/R.
The CDF 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 CDMA LMF Operator’s Guide, or the LMF
Help screen, for more information.
Site Equipage Verification
If you have not already done so, use an editor to view the CDF, and
review the site documentation. Verify the site engineering equipage data
in the CDF to the actual site hardware.
CAUTION
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.
Isolate BTS from T1/E1 Spans
NOTE
At active sites, the OMC/CBSC must disable the BTS and place
it out of service (OOS). DO NOT remove the span surge
protectors until the OMC/CBSC has disabled the BTS.
Each frame is equipped with one 50-pair punch block for spans,
customer alarms, remote GPS, and power cabinet alarms. See Figure 3-2
and refer to Table 3-1 for the physical location and pin call-out
information. To disable the span, pull the surge protectors for the
respective span.
Before connecting the LMF to the frame LAN, the OMC/CBSC must
disable the BTS and place it OOS to allow the LMF to control the
CDMA BTS. This prevents the CBSC from inadvertently sending
control information to the CDMA BTS during LMF based tests.
