Overview

Code can be downloaded to a device that is in any state. After the

download starts, the device being downloaded changes to

OOS_ROM (blue). If the download is completed successfully, the device

changes to OOS_RAM with code loaded (yellow). Prior to downloading

a device, a code file must exist. The code file is selected automatically if

the code file is in the /lmf/cdma/n.n.n.n/code folder (where n.n.n.n is the

version number of the download code that matches the “NextLoad”

parameter in the CDF file). The code file in the code folder must have

the correct hardware bin number. Code can be automatically or manually

selected.

Data must be downloaded to a device before the device is placed INS.

The CSM must be INS before an MCC can be put INS. The devices to

be downloaded are as follows:

 Master Group Line Interface (MGLI2)

 Clock Sync Module (CSM)

 Multi Channel Card (MCC)

 Broadband Transceiver (BBX2)

The MGLI must be successfully downloaded with code and

data, and put INS before downloading any other device.

The download code process for an MGLI automatically

downloads data and then enables the MGLI before

downloading other devices.

IMPORTANT

Downloading requires a few minutes. After the download starts, the

device being downloaded changes to OOS_ROM (blue). If the download

is completed successfully, the device changes to OOS_RAM (yellow)

with code loaded (INS_ACT (green) for MGLI).

Download Code

Follow the steps in Table 3-16 to download the firmware application

code.

When downloading multiple devices, the download may

fail for some of the devices (a time out occurs). These

devices can be downloaded separately after completing the

multiple download.
