FEB 2005 1X SC 4812T Lite BTS Optimization/ATP 3-39
PRELIMINARY
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.
– If you must download ROM Code, the procedures are located in
Appendix G.
Before ROM Code can be downloaded from the LMF, the correct ROM
Code File for each device to be loaded must be present on the LMF
Computer. ROM Code must be manually selected for download.
The ROM Code File is not available for GLI3s. GLI3s are
ROM Code loaded at the factory.
NOTE
ROM Code can be downloaded to a device that is in any state. After the
download is started, the device being downloaded changes 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 SCt CDMA Release Notes
(supplied on the tape or CD–ROM containing the BSS Software).
RAM Code
Before RAM Code can be downloaded from the LMF, the correct RAM
Code File for each device must be present 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.
