VERIFY YOUR
CONNECTION
FOR SINGLE COMPUTER CONNECTED
DIRECTLY TO A CABLE MODEM, OR ONE OR
MORE COMPUTERS CONNECTED TO A
CABLE MODEM THROUGH A HOME ROUTER
CABLE MODEM
AVerify that your PWR, LAN, and WAN lights
are steady green and that you can browse to
a known Web site (e.g. www.att.com). If your
lights are not steady green, see Troubleshooting,
pages 25-26. If your lights are steady green
and you cannot browse, see “I get a Page Not
Found error when attempting to browse” in
Troubleshooting, page 26.
B Proceed directly to Step 6, page 16.
VERIFY YOUR CONNECTION
NOTE WHETHER YOU HAVE A CABLE
MODEM OR DSL.
CABLE MODEM
IF YOU HAVE A CABLE MODEM,
FOLLOW THE INSTRUCTIONS TITLED
“CABLE MODEM” IN GREEN.
DSL
IF YOU HAVE DSL, FOLLOW
THE INSTRUCTIONS TITLED “DSL”
IN BLUE.

FOR SINGLE COMPUTER CONNECTED DIRECTLY TO DSL MODEM
AMake sure your home router is configured to obtain IP address automatically.
Please refer to your home router’s user manual (for most routers, go to WAN
settings in the router configuration tool and set “obtain IP address automatically;”
this puts your router into what is known as DHCP mode. It may also be called
“cable” or “Internet” mode).
Continue with Step B.
FOR ONE OR MORE COMPUTERS CONNECTED TO DSL MODEM THROUGH HOME ROUTER
AMake sure your computer is configured to obtain IP
address automatically. (For most customers, your
computer should already be set to obtain IP address
automatically.) Please refer to your computer’s
online help for how to do this. (Instructions for
common computers are provided in Troubleshooting,
pages 26-27.)
You will no longer need to activate the software
installed by your DSL provider to access the Internet;
the TA will handle this. For additional information
see “I have DSL and am getting the message ‘can’t
connect to the Internet’ even though I can see the
Internet” in Troubleshooting, page 27.
Continue with Step B.
DSL
VERIFY YOUR CONNECTION
Sample: Your router’s control
panel may look different
13
NOTE Most DSL providers use PPPoE to provide customers access to their network.
This section assumes like most DSL customers you have PPPoE; however, if you
are certain you don’t have PPPoE and instead have DHCP or Static IP, follow the steps
in green for cable modem users (for DHCP) or Appendix B (for Static IP).
!IMPORTANT! Check to see if you can browse to a known website (e.g. www.att.com). If you can browse, proceed directly to Step 6,
page 16. If you cannot browse, you will need to configure your connection using the steps below.

website (e.g. www.att.com)
(H2). If you cannot browse,
restart your PC.

the note to the right.

NOTE
If your PWR, LAN, and WAN lights are
steady green and you cannot browse, you
may have problems connecting with your
DSL service.
Recommended actions:
– Check to see if your PPPoE username
and password are correct. (You may
need to contact your DSL Service
provider to verify your PPPoE username
and password.)
– Make sure your cabling is correct
according to Step 3.
– Power all devices down and unplug
your DSL modem and home router.
Power up your DSL modem, wait until
all appropriate indicator lights are lit.
Plug your TA into a power outlet.
Power up your router (if you have one).
Turn on your computer(s).
NOTE
A few DSL customers have
what is known as static IP,
in which their computer
has a permanent IP address
that never changes. Most
customers instead have
PPPoE or DHCP, and should
use the instructions above;
however if you are sure you
have a static IP address and
not PPPoE or DHCP, see the
configuration instructions
in Appendix B, page 20.
For additional info see
“I may have a static IP
address but I am not sure”
in Troubleshooting, page 28.

This was part of the informa-
tion to gather in Step 1.
CYou should see the screen
on the left. Click “Activate
TA” and follow the
instructions on the screen.
During the “Receive
Updates” screen the lights
on the front of your TA
will blink and your TA will
reboot itself. When this
process is complete your
CA light will turn a steady
green and you will hear a
single short ring. Do not
hit the “continue” button
on this screen until the
CA light becomes a steady
solid green. This process
may take several minutes.
DO NOT turn the TA off
while this sequence is
underway.
DClick “Get Started” on the
“TA Activation Complete”

handset and listen for a
dial tone. If you don’t hear
a dial tone, hang up, wait a

This alternative setup has the
advantage that you do not need to
reconfigure your router or PCs,
but it has the disadvantage that
your data connection may interfere
with your voice connection and
reduce call quality.
To perform the alternative setup and
connect your TA behind the router:
AMake sure you have your
AT&T CallVantage®Service
User ID and password handy,
as described in Step 1.
BSet up your cabling as shown
in the diagram on the following
page. There is no need to turn
off or disconnect your cable/
DSL modem, router, or any PCs
connected to your router.
CPower up your TA by plugging
it into a power outlet.
DMake sure your telephone
is connected to your TA
and plugged into a power outlet
(if necessary).
EFollow Step 6, Activate your
TA.
Congratulations! Setup is now
complete! You can start making
calls by dialing the 10-digit
number from the phone connected
to your Telephone Adapter.
You can also use the new advanced
features available on your AT&T
CallVantage Service Home Page at
