Installing Your Tango
Connect Your Tango
1. Plug the power adapter into the Power port and into an AC power outlet.
Caution: The power supply looks very similar to the phone connector.
Please make sure you don't plug the power supply to the LINE port as this
will damage the unit.
2. Plug your home telephone into the Line port on the adapter.
Caution: Do not connect Tango to a regular telephone wall jack.
3. The Power LED will light up (Red) while your Tango boots up and connects to
the 8x8network. This light will turn orange once your unit is registered with
8x8. When the boot-up process is completed, the LCD screen will display a
background screen with 4 icons.
Note: Boot up time may take up to 10 seconds.

8
Configure Your Tango
The Tango can function as your primary gateway/router or as a client within an
existing network configuration.
If you currently have broadband access and a gateway/router installed at your loca-
tion, you may add the Tango as a client to your network. If you currently have
broadband Internet access and do not have a router, you may install your Tango as
the primary router to your network.
Installing the Tango with an existing network configuration/router.
Plug one end of the enclosed Ethernet cable into the WAN port on the back of the
Tango. Plug the other end of the Ethernet cable into your router/gateway, which is
connected to your broadband modem. The Tango will automatically obtain an IP
address from your existing router.
Installing the Tango as your primary gateway/router.
The Tango supports the two most common broadband connection protocols:
DHCP (most common connection type found with Cable Modem) and PPPoE (most
DSL providers use this connection type).
Choose on of the following three set up options that follow:
1. Setting up with DHCP
The Tango is configured for use with Dynamic Host Configuration Protocol
(DHCP) by default. If your broadband connection uses DHCP, simply connect
your phone's WAN port to your broadband and then connect the phone's
power cord to an AC power outlet.
2. Setting up with PPPoE
If your broadband connection uses PPPoE, you will need to configure the
Tango built-in router by inputting the user name and password provided by
your Internet Service Provider. Follow the steps below to configure the Tango
for use with PPPoE-based connection.
1. Connect a computer with a web browser directly to the LAN port of your Tango.
2. Type http://192.168.88.1 (the default IP address of your Tango) into the address
bar of your web browser. Then press the Enter key. You will be prompted to
enter a password (the default password is admin).

you are not sure, leave this blank.
9. Click APPLY.
3. Setting up with Static IP Address
If your broadband provider has given you a static IP address, you will need to enter
that information in the Tango. Follow the steps below to configure the Tango for
use with a Static IP address...
1. Connect a computer with a web browser directly to the LAN port of your
Tango.

16
Setup Menu
Use this menu to configure the following video settings:
Video Settings
Available Bitrate - The upstream bitrate of the Tango user's broadband
connection link.
Send Periodic iFrame - The “On” and “Off” settings for "Send Periodic iFrame"
enable and disable sending INTRA frames at regular intervals. The "Auto" setting
instructs the endpoint to determine if the remote endpoint can request INTRA
frames and, if not, send INTRA frames at regular intervals. This setting controls
whether the Tango sends unsolicited INTRA frames (also known as keyframes or
Fast Updates). These INTRA frames clean up the video when packets are dropped.
It is recommended that this setting be placed on “Auto”, as it may cause a brief
pause in the video.
iFrame Frequency - This setting manages the frequency unsolicited INTRA frames
are sent for “On” and “Auto” settings of “Send Periodic iFrame”. For example, an
“iFrame Frequency” setting of “4 seconds” will cause the Tango to send an INTRA
frame every 4 seconds.
General Display Settings
Color Theme - You can choose different colors for the background and text.
Wallpaper - Choose a preprogrammed background image from your Tango or
upload and personalize with your own pictures/images (See Digital Photo Frame
section below).
Menu Transparency - Choose level of transparency for your menu background.
Screen Saver - Set the amount of time you would like to elapse before starting your
screen saver. You can choose Picture Frame as your screen saver, which will enable
and scroll through your customized images (See Digital Photo Frame on page 17).
Hide Main Menu - Select when you would like the main menu to disappear from
your LCD screen.
Display Brightness - Adjust the brightness of your LCD screen.
