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 or factory repair. 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 CDMA 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 in the
device does not match the 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 Release 9.2
software where a GLI loaded with Release 2.8.1 ROM code must be
installed to replace a malfunctioning MGLI.
Before ROM code can be downloaded from the CDMA 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
OOSROM (blue). The device will remain OOSROM (blue) when the
download is completed. The same Revisionlevel RAM code must then
be downloaded to the device. For example, if Release 2.9.2.1.1 ROM
code is downloaded, Release 2.9.2.1.1 RAM code must be downloaded.
Procedures to load ROM code are located in Appendix G.
RAM Code
Before RAM code can be downloaded from the CDMA 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 CDMA LMF file structure. The RAM code file will be selected
automatically if the file is in the \lmf\cdma\loads\n.n.n.n\code folder
(where n.n.n.n is the version number of the download code that matches
the NextLoad parameter of the CDF file). The RAM code file in the
code folder must have the correct hardware bin number.
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). When code is downloaded to an MGLI
or GLI, the CDMA LMF automatically also downloads data and then
enables the MGLI. When enabled, the MGLI will change to INS (green).
For nonGLI devices, data must be downloaded after RAM code is
downloaded. To download data, the device state must be OOSRAM
(yellow).
