Hardware Installation
Front Panel
Step 1
Connect the DSL 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).
Note:
Use 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.
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.
Port
Function
DSL
Connects the device to an ADSL telephone jack or splitter using a RJ-11
telephone cable
LAN
Connects the device to your PC's Ethernet port, or to the uplink port
on your hub/switch, using a RJ-45 cable
Reset
System reset or reset to factory defaults.
POWER
Connects to the supplied power adapter
Switches the unit on and off

5
Note: Without the splitter, transient noise from the telephone can interfere with the
operation of the ADSL router. As a result, the ADSL router may introduce noise to the
telephone line. To prevent this from happening, a small external splitter must be
connected to each telephone.
PC Configuration
Windows
1. In the Windows task bar, click the “Start” button, point to “Settings”, and then
click “Control Panel”.
2. Double-click the “Network” icon.
3. On the “Configuration” tab, select the TCP/IP network associated with your
network card and then click “Properties”.
4. In the “TCP/IP Properties” dialog box, click the “IP Address” tab. Set the IP
address as 192.168.1.2 and the subnet mask as 255.255.255.0.
5. On the “Gateway” tab, set a new gateway as 192.168.1.1, and then click “Add”.
6. Configure the “DNS” tab if necessary to 192.168.1.1, usually NOT needed.
7. Click “OK” twice to confirm and save your changes.
8. You will be prompted to restart Windows. Click “Yes”.
Access the Unit
After configuring the IP Address of you computer, power on the ADSL Router, and launch a
web browser and navigate to http://192.168.1.1 to log on to the setting pages.
Attention: the username admin and password adslroot are both lowercase.

Quick Setup
If there are no pre-configured PVCs in the router, you can find the Quick Setup option on the
left of router configuration page. The user can also delete the PVCs pre-configured to find the
option.
1. From home page, choose Quick Setup.
2. Deselect the check box to disable the DSL Auto-connect process. Set the VPI/VCI
value provided by your ISP.

7
a. PPP over Ethernet (PPPoE)
1. Select PPP over Ethernet (PPPoE) as connection type, and select
LLC/SNAP-BRIDGING as encapsulation mode.

8
3. Input the PPP Username & PPP Password and then click Next. The user interface
allows a maximum of 256 characters in the user name and a maximum of 32
characters in the password. Just remember to enable NAT and Firewall as shown
below.
4.
PPPoE service name can be blank unless your Internet Service Provider gives you a value
to enter.
Authentication method is default to Automatic. It is recommended that you leave the
Authentication method in Automatic, however, you may select PAP or CHAP if necessary.
The default value for MTU (Maximum Transmission Unit) is 1500 for PPPoA and 1492 for
PPPoE. Do not change these values unless your ISP asks you to.
The gateway can be configured to disconnect if there is no activity for a specific period of time
by selecting the Dial on demand check box and entering the Inactivity timeout. The entered
value must be between 1 minute and 4320 minutes.
The PPP IP Extension is a special feature deployed by some service providers. Unless your
service provider specifically requires this setup, do not select it. If you need to select it, the
PPP IP Extension supports the following conditions:
It allows only one computer on the LAN.
The public IP address assigned by the remote using the PPP/IPCP protocol is
actually not used on the WAN PPP interface. Instead, it is forwarded to the
computer's LAN interface through DHCP. Only one system on the LAN can be

9
connected to the remote, since the DHCP server within the ADSL gateway only
has a single IP address to assign to a LAN device.
NAPT and firewall are disabled when this option is selected.
The gateway becomes the default gateway and DNS server to the computer
through DHCP using the LAN interface IP address.
The gateway extends the IP subnet at the remote service provider to the LAN
computer. That is, the PC becomes a host belonging to the same IP subnet.
The ADSL gateway bridges the IP packets between WAN and LAN ports, unless
the packet is addressed to the gateway's LAN IP address.
3. Deselect Enable IGMP Multicast, and select Enable WAN Service and then click
Next.
5. Configure the DSL Router’s IP Address and Subnet Mask for LAN interface. In this
page, you can use DHCP (Dynamic Host Configuration Protocol) to control the
assignment of IP addresses on your local network (LAN only).
