PRELIMINARY

CSA devices are RAM code–loaded at the factory. RAM

code is downloaded to CSA only if a newer software

version needs to be loaded.

When downloading to multiple devices, the download may

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

devices can be loaded individually after completing the

multiple download.

NOTE

Follow the steps in Table 6-15 to download RAM code and data to

non–GLI devices.

Table 6-15: Download RAM Code and Data to Non–GLI Devices

n Step Action

1 Select the target CSA, MCC, and/or BBX device(s) by clicking on them.

2 Click Device in the BTS menu bar, and select Download > Code/Data in the pull–down menus.

– A status report is displayed that shows the results of the download for each selected device.

3 Click OK to close the status report window when downloading is completed.

NOTE

After a BBX, CSA, or MCC device is successfully loaded with RAM code and data have changed

to the OOS_RAM state (yellow), the status LED should be rapidly flashing GREEN.

NOTE

The command in Step 2 loads both code and data. Data can be downloaded without doing a code

download anytime a device is OOS–RAM using the command in Step 4.

Selecting CSA Clock Source

Synchronization and Alarm (CSA) in the CSA System Time – GPS &

HSO/MSO Verification section of this chapter.

Select CSA Clock Source

A CSA can have three different clock sources. The CSA Source function

can be used to select the clock source for each of the three inputs. This

function is only used if the clock source for a CSA needs to be changed.

The Clock Source function provides the following clock source options.
