6-36 1X SC480 BTS Hardware Installation, Optimization/ATP, and FRU MAY 2004

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 C.

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.

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 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 Base Station System

(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 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.
