User Interface
ACCESSING CSA
The User Interface to the ADSL Modem is provided by the Control and Status
Application (CSA). You can access the CSA by double-clicking on the CSA icon
in the System Tray, located near the clock on the task bar. The icon, which ap-
pears as two monitor screens, also changes color to indicate the status of the mo-
dem (see Table 1. ICON Condition.).
If the icon does not appear in the System Tray, it can be restored by any of the fol-
lowing methods:
• Restart the PC.
• Click the Windows START button, then Programs, ADSL Modem Driver, and
Add CSA Tray Icon.
• Go to the CONTROL PANEL and double-click the ADSL Control and Status
icon.
While connected, the System Tray CSA icon provides pop-up text that gives infor-
mation about the current ADSL connection. This text appears when the cursor is
placed over the icon. The information displayed is:
• bytes transmitted
• bytes received
• connection rate.

Modem Performance
The Modem Performance displays performance information. The primary purpose
is to display the instantaneous throughput rate for both transmit and receive paths
of the modem. This rate is calculated based on the poll period (generally 2 seconds)
and the number of bytes passed during that time.
Transmit and Receive
The throughput is indicated through two bar graphs, each provides a maximum rate
label indicating the transmit and receive bit rates currently in use. The bar graph
displays peak throughput rates over the last 10-second period. Basically, the user
interface records the instantaneous throughput for each poll period over the last 10
seconds, and the peak rate is displayed as the maximum value achieved over that
10-second period. This value is indicated on the throughput graph with a vertical
red marker indicating the peak rate.
The user interface displays operational information about the ADSL modem, rele-
vant when the modem is connected. When the modem is not connected, all of the
non-averaged operational information are reported as zero unless otherwise CSA
User Screen Connection Status noted. This means that when the modem is dis-
connected, these values should immediately report zero.
Connection Status
The Connection Status field changes to indicate the status of the modem connec-

tion:
• ADSL link connected
• ADSL link disconnected
Device Status
The Device Status field changes to indicate the status of the modem connection:
• ADSL Modem available
• ADSL Modem not available
Connect/ Disconnect Button
The CONNECT/DISCONNECT button performs the connection/disconnection op-
eration. If the ADSL Modem is unavailable, the button is disabled. This occurs
when the ADSL modem driver is disabled or fails to communicate correctly.
Close Button
The CLOSE button closes the main interface screen. If the main window was dis-
played while the system tray icon was present, then the application continues to
execute - hiding the main screen. If for some reason the icon is not present, how-
ever, the application is terminated.
Help
On-line help is available through the HELP screens. Press the F1 key at the CSA
main screen to see the Help table of contents. This is available from the context
menus and system tray icon menus Help selection.
AboutCSA
The ABOUTCSA button displays the product information, including the version

Troubleshooting
If your internet connection is not working, the following hints may be helpful. After
trying these hints, if you still can not make your connection work, it is recom-
mended that you ask your service provider for assistance. To run troubleshooting
on the system:
Step 1. Is the system tray CSA icon green? If it is not, try a restart of your PC. This
may clear the problem.
Step 2. If this does not correct the problem, make the following checks:
Step a. Is your phone line connected to the wall outlet and to your modem?
Step b. For USB. Is the modem connected to the USB port?
Step 3. If the CSA icon color does not show green after performing the steps
above, it is recommended to "cleanup" the installation and reinstall. "Cleanup" is a
utility that can be run from the Installation CD. At the Windows Start button, select
Run, click Browse and search for "Cleanup.exe" on the installation CD. Once you
Run the utility, it pops up a message for restarting the system. Re-install the mo-
dem after a restart.
Step 4. If the CSA tray icon is still not showing green uninstall the modem (see
“Chapter 5. Uninstall Modem”) and re-install.
Step 5. If the system tray CSA icon is green, but you have problems in logging in,
or connecting to, your ISP, running "Cleanup’ and reinstalling may solve the prob-
lem (see "Step 3" for details).
Step 6. If still experiencing difficulties, contact your service provided for help.
