1.OVERVIEW
1.1 ABOUT ADSL
An ADSL MODEM is a broadband Internet access device, which utilizes the high frequency
segment of the phone line to transmit high-speed data without affecting the voice transmission. The
frequency of the ADSL signal is higher than that of voice, so voice and ADSL signal can coexist in one
line by using a splitter to insulate each from the other. ADSL data transfer adapts the asymmetry model.
It supports upload transmission speed up to 1Mbps and download speed up to 8 Mbps (24Mbps for
ADSL2+). ADSL is an ideal device for broadband access.
1.2 ABOUT ADSL2/2+
Transmission performance of ADSL2 is improved comparing with the first generation of ADSL.
These improvements are mainly concerned with long distance, anti-line-loss, anti-noise, etc. By
doubling the transmission bandwidth, ADSL2+ has implemented a downlink rate as high as 24 Mbps.
Therefore, Internet applications such as synchronous transmission of multi video stream, online
games and huge capacity of downloading files are made possible.
1.3 FEATURES
1、Support ANSI T1.413 ISSUE 2、ITU G.992.1 (G.DMT)、ITU G.992.2 (G.LITE)、ITU G992.3、
ITU G992.5
2、Web-based configuration and monitoring.
3、Support multiple PVCs.
4、Routing function.
5、NAPT、DHCP function.

3. CONFIGURATION
3.1 DEFAULT CONFIGURATION
ADSL MODEM has pre-configured with the VCI/VPI which is in common use. The default dial-up
mode is bridge encapsulation. For bridge mode, no need to configure any more parameter. However,
the third party dial-up software is needed for connection with the Internet.
3.2 COMPUTER CONFIGURATION
The default IP address for ADSL MODEM is: 10.1.1.1; The Subnet Mask is：255.0.0.0. Users can
configure ADSL MODEM through an Internet browser. ADSL Modem can be used as gateway and
DNS server; users need to set the computer’s TCP/IP protocol as follow:
1、Set the computer IP address at same segment of ADSL Modem, such as set the IP address of
the network card to one of the “10.1.1.2”～“10.1.1.254”.
2、Set the computer’s gateway the same IP address as the ADSL Modem’s.
3、Set computer’s DNS server the same as ADSL Modem’s IP address or that of an effective
DNS server.
3.3 ADSL MODEM CONFIGURATION
3.3.1 LOG IN
Open the browser; input http://10.1.1.1 at the address column. Press “Enter” key then the entry
dialog box will show up as Figure 3.1. Input Username: admin , Password: admin (capital sensitive),
then press Enter.

3.3.2 SAVE SETTING
After getting through each page for parameters setting, click “Save” or “Save apply” to store the
value in ADSL Modem. Briefly, we named “Save”.
Note
：：
When you save the settings, the web page will be refreshed slowly, please wait it finished.
After you save the settings, it will take effect until next reboot.
Some settings only take effect after rebooting the router.
3.4 WAN CONFIGURATION
If the configuration is bridge encapsulation, there is no need to configure any more parameters.
Only need to use the third party dial-up software to connect the Internet.
Totally, this router supports：PPPoA、PPPoE、MER、IPoA、Bridging. For detail configuration
information, please check the following configuration guide.
3.4.1 CONFIGURATION GUIDE
Click “WAN” on the left page, enter into “WAN” configuration page.
Note: At most we can have eight connections. If you need to add a new connection, please
delete or modify an existing connection.

Click on the next connection which you want modify. Press “Edit” button, enter the configure guide,
as Figure 3.3
Figure 3.3
The value for VPI/VCI is assigned by your ISP. After inputting the PVC value, press “Next” into
“connection type”. As Figure 3.4.

The Modem supports five ADSL protocol modes. Choose the protocol which is appointed by ISP
and PVC encapsulation, click “Next” enter to the protocol configure. Below, we introduce the
configurations of the five protocol modes.
•PPP over ATM (PPPoA) •PPP over Ethernet (PPPoE)
•MAC Encapsulated Routing (MER) •IP over ATM (IPoA)
•Bridging
Some connection lines need to confirm the LLC or VC, if you can’t confirm, please don’t modify
the default value or ask your ISP.
3.4.2 RFC1483 BRIDGE CONFIGURATION
Select the Bridging mode. Then press “Next” to specify the Service Name, and select the “Enable
Service” as Figure 3.5.
Figure 3.5
Press “Next” to enter into “WAN configuration”, click “save” to save configuration, if you need to
modify the parameter, click “back” as Figure 3.6.

3.4.3 PPPOE CONFIGURATION
PPPoE is also known as RFC 2516. It is a method of encapsulating PPP packets over Ethernet.
PPPoA is also known as RFC2364 and named as Peer to Peer Protocol over ATM. As PPPoE, it
also has all the features of PPP. Although it’s based on ATM protocol, the setting of all the other
parameters is similar with PPPoE. So we only introduce PPPoE in detail here.
In Figure 3.4, select PPP over Ethernet (PPPoE), press “Next step” entering the configuring interface,
as Figure 3.8.
Figure 3.8
PPP Username: Your account from ISP to access Internet.
PPP Password: Input the password assigned by your ISP.
PPPoE service name: Server name of network ISP. No need to set.
Authentication Method: Authentication mode of network ISP. Default is AUTO.
Dial on demand: When this mode is selected, the connection that has no traffic within assigned
disconnect timeout (e.g. 1 minute) will be automatically disconnected. The connection
will be activated again when traffic arrives. This function is advantageous for users
who are charged with online time. It should be noticed that some programs
automatically link to Internet. Computer will send data to network when infected by
virus. Connection will not be disconnected under these data streams.
Inactivity Timeout (minutes) [1-4320]: When “Connection on demand” is selected, this input box
indicates that after how
long the connection will be disconnected in the absence of traffic. If the value is 0, connection will
not be disconnected.
PPP IP Extension: 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.
