SC4812ET BTS Optimization/ATP — CDMA LMF
Jan 2002
3-38
Overview
Before a BTS can operate, each equipped device must contain device
initialization (ROM) code. ROM code is loaded in all devices during
manufacture, factory repair, or, for software upgrades, from the CBSC
using the DownLoad Manager (DLM). Device application (RAM) code
and data must be downloaded to each equipped device by the user before
the BTS can be made fully functional for the site where it is installed.
ROM Code
Downloading ROM code to BTS devices from the LMF is NOT routine
maintenance or a normal part of the optimization process. It is only
done in unusual situations where the resident ROM code release level in
the device is not compatible with the required release level of the site
operating software and the CBSC can not communicate with the BTS to
perform the download. An example would be a BTS loaded with R16.0
software where a GLI which is factory–loaded with R9.2.x or earlier
ROM code must be installed to replace a malfunctioning GLI.
Before ROM code can be downloaded from the LMF, the correct ROM
code file for each device to be loaded must exist on the LMF computer.
ROM code must be manually selected for download.
ROM code can be downloaded to a device that is in any state. After the
download is started, the device being downloaded will change to
OOS_ROM (blue). The device will remain OOS_ROM (blue) when the
download is completed. A compatible revision–level RAM code must
then be downloaded to the device. Compatible code loads for ROM and
RAM must be used for the device type to ensure proper performance.
The compatible device code release levels for the BSS software release
being used are listed in the Version Matrix section of the SC CDMA
Release Notes (supplied on the tape or CD–ROM containing the BSS
software).
Procedures to load ROM code are located in Appendix J.
RAM Code
Before RAM code can be downloaded from the LMF, the correct RAM
code file for each device must exist on the LMF computer. RAM code
can be automatically or manually selected depending on the Device
menu item chosen and where the RAM code file for the device is stored
in the LMF file structure. The RAM code file will be selected
automatically if the file is in the <x>:\<lmf home
directory>\cdma\loads\n.n.n.n\code folder (where n.n.n.n is the
download code version number that matches the “NextLoad” parameter
of the CDF file). The RAM code file in the code folder must have the
correct hardware bin number for the device to be loaded.
RAM code can be downloaded to a device that is in any state. After the
download is started, the device being loaded will change to OOS_ROM
(blue). When the download is completed successfully, the device will
change to OOS_RAM (yellow).
