1.2 Safety Precautions
Follow the following instructions to prevent the device from risks and damage caused
by fire or electric power:
Use volume labels to mark the type of power.
Use the power adapter packed within the device package.
Pay attention to the power load of the outlet or prolonged lines. An
overburden power outlet or damaged lines and plugs may cause electric
shock or fire accident. Check the power cords regularly. If you find any
damage, replace it at once.
Proper space left for heat dissipation is necessary to avoid damage caused
by overheating to the device. The long and thin holes on the device are

2
designed for heat dissipation to ensure that the device works normally. Do
not cover these heat dissipation holes.
Do not put this device close to a place where a heat source exists or high
temperature occurs. Avoid the device from direct sunshine.
Do not put this device close to a place where it is over damp or watery. Do
not spill any fluid on this device.
Do not connect this device to any PCs or electronic products, unless our
customer engineer or your broadband provider instructs you to do this,
because any wrong connection may cause power or fire risk.
Do not place this device on an unstable surface or support.

2 Hardware Installation
To connect the device, do as follows:
Step 1 Connect the ADSL interface of the device and the Modem interface of
the splitter through a telephone cable. Connect the phone to the Phone
interface of the splitter through a cable. Connect the incoming line to the
Line interface of the splitter.
The splitter has three interfaces:
Line: Connect to a wall phone jack (RJ-11 jack).
Modem: Connect to the ADSL jack of the device.
Phone: Connect to a telephone set.
Step 2 Connect the LAN interface of the device to the network card of the PC
through an Ethernet cable (MDI/MDIX).
INote:
Use the twisted-pair cables to connect with the hub or switch.
Step 3 Plug one end of the power adapter to the wall outlet and connect the
other end to the Power interface of the device.
Connection 1
Figure 3 shows the application diagram for the connection of the router, PC, splitter
and the telephone sets, when no telephone set is placed before the splitter.

8
Figure 3 Connection diagram (Without connecting telephone sets before the splitter)
Connection 2
Figure 4 shows the connection when the splitter is installed close to the router.
Figure 4 Connection diagram (Connecting a telephone set before the splitter)
Note:
When connection 2 is used, the filter must be installed close to the telephone
cable. See Figure 4. Do not use the splitter to replace the filter.

9
Installing a telephone directly before the splitter may lead to failure of connection
between the device and the central office, or failure of Internet access, or slow
connection speed. If you really need to add a telephone set before the splitter, you
must add a microfilter before a telephone set. Do not connect several telephones
before the splitter or connect several telephones with the microfilter.

3 About the Web Configuration
This chapter describes how to configure the router by using the Web-based
configuration utility.
3.1 Access the Router
The following is the detailed description of accessing the router for the first time.
Step 1 Open the Internet Explorer (IE) browser and enter http://192.168.1.1.
Step 2 In the Login page that is displayed, enter the username and password.
Figure 5 Login window
Note:
The username and password of the super user are admin and admin.
The username and password of the common user are user and user.
If you log in as a super user, you can check, configure and modify all the settings.

11
If you log in as a common user, you can check the status of the router, but can not
configure the most of the settings.
Note:
In the Web configuration page, you can click Apply Changes to save the
settings temporarily. If you want to save the settings of this page permanently,
click save of Attention that appears on the left pane of the Web page after the
configuration.
3.2 Wizard
When subscribing to a broadband service, you should be aware of the method by
which you are connected to the Internet. Your physical WAN device can be either PPP,
ADSL, or both. The technical information about the properties of your Internet
connection is provided by your Internet Service Provider (ISP). For example, your ISP
should inform you whether you are connected to the Internet using a static or dynamic
IP address, and the protocol that you use to communicate on the Internet.
The Wizard page guides fast and accurate configuration of the Internet connection
and other important parameters. The following sections describe these various
configuration parameters. Whether you configure these parameters or use the default
ones, click Next to enable your Internet connection. In the navigation bar, choose
Wizard. The page shown in the following figure appears.
