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 ofADSL. 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.

2.2 HARDWARE CONNECTION
Introduction：
1、Use a telephone cord to connect the LINE port of the splitter with the RJ-11 port (the phone jack) on
the wall.
2、Use another telephone cord to connect theADSL port of the splitter with the LINE port of the ADSL
Modem.
3、Use another telephone cord to connect the telephone set with the PHONE port of the splitter.
4、Connect Ethernet port of theADSL MODEM with 10/100BASE-T port of the computer using the
network cable that comes with the modem.
5、Plug in the power cord, and turn on the power.
If you do not want Internet services and telephone voice services simultaneously, please just connect the
LINE port of the ADSL Modem with the RJ-11 port (the phone jack) on the wall using a telephone cord. In this
case, the splitter is not necessary.

3. CONFIGURATION
3.1 DEFAULT CONFIGURATION
ADSL MODEM has pre-configured with the VCI/VPI which is in common use.
3.2 COMPUTER CONFIGURATION
The default IP address for ADSL MODEM is: 192.168.1.1; The Subnet Mask is：255.255.255.0. Users can
configureADSL 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 ofADSL MODEM, such as set the IP address of the
network card to one of the “192.168.1.2”～“192.168.1.254”.
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://192.168.1.1 at the address column. Press “Enter”key then the entry dialog
box will show up as Figure 3.1. Input Username: admin , Password: password (capital sensitive), then press
Enter.
Figure 3.1
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.
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 VIEW WAN SERVICE
Click “Device Info”on the left page, enter into “WAN”page.
NOTE:At most we can support eight connections. We will support Edit existed connections later. In
the latest firmware, there no need reboot the device when you add/remove/edit one wan connection.
It will take effect immediately.
Figure 3.2
3.4.2 RFC1483 BRIDGE ON ATM CONFIGURATION
Click “Advanced Setup” on the left page, enter into “Layer2 Interface” configuration page, where we can select
the type of Layer2-Interface,ATM or ETH.
NOTE:ATM interface is our most commonly used mode, which will transport data on DSLline via
Bridge or Route Connections. And, ETH Interface can be used as LAN-UP Interface , the details will
be introduced in subsequent chapters.
Select ATM Interface , then click “Add” button to add one NEW Interface of Layer2.Then input appropriate
VPI/VCI, select EOA used for IPoE , PPPoE, Bridge.Select Encapsulation Mode and Service CateGory,
Connection Mode(Default,VLAN-MUX,MSC).If QOS need, please select “Enable quality Service”. Usually,
you only need to setup VPI/VCI to the value assigned by your ISP .At last click “Apply /Save” button to save
the configuration.

3.4.3 PPPOE ON ATM 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 3.6, select PPP over Ethernet (PPPoE)

Press “Next”entering the configuring interface, as Figure3.9.
Figure 3.9
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 isAUTO.
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: When “Dial 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.
Enable manual MTU set: set MTU value manually by yourself
Manual Connect:connect/disconnect PPPoE connection manually
