DSL Gateway/Router — User Manual 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.
DSL Gateway/Router — User Manual 2 SPECIFICATION 2.1 INTERFACE INTRODUCTION 2.1.1 INDICATOR AND INTERFACE Table 2.1 ITEM Indicator Interface Name State introduction POWER A steady red light means the power connection works properly DSL Yellow, shows DSL line status. INTERNET Green, Flashing means the Modem is transmitting or receiving data WLAN Green, Indicates status of connection to the wireless device LINE Connected with phone line or “ADSL” port of the splitter.
DSL Gateway/Router — User Manual 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 the ADSL 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.
DSL Gateway/Router — User Manual 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: 192.168.1.1; The Subnet Mask is：255.255.255.0.
DSL Gateway/Router — User Manual 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.
DSL Gateway/Router — User Manual Figure 3.3 l The value for VPI/VCI is assigned by your ISP. After inputting the PVC value, press “Next” into “connection type”. As Figure 3.4. 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 configuraion of the five protocol modes.
DSL Gateway/Router — User Manual 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. Figure 3.6 Note：When you use bridge mode, please close “DHCP SERVER”, the result as Figure 3.

DSL Gateway/Router — User Manual 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.
DSL Gateway/Router — User Manual disconnected. Press “Next step” when configuration is finished. The following operation is same with Figure 3.5. Notice that PPPoE mode does not work until the modem is reset. 3.4.4 STATIC ADDRESS In Figure3.4, select MAC Encapsulation Routing (MER), press “Next”, and the configuration can be queried from your ISP, the result as Figure3.9. Figure 3.
DSL Gateway/Router — User Manual 3.5 WIRELESS CONFIGURATION Press “Wireless” on the top of web pages to enter wireless section. You can select to configure wireless setup, security and management. 3.5.1 WIRELESS SETUP Click “Setup” on the left menu to setup basic wireless parameters. In default, check “Enable Ｗireless” box to launch wireless AP. l l SSID (Service Set Identifier): The mobile users cannot access WLAN until setting their SSID as the same value of the wireless ADSL.
DSL Gateway/Router — User Manual Encryption Strength: Key length: 128bits or 64bits. Network Key 1-4: Up to four keys that are in form of hex digitals could be set. Mobile users can’t access the AP if they haven’t set the same key as AP. For 64bits and 128bits keys, you should input 10 and 26 hexadecimal digitals or 5 and 13 ASCII characters respectively. Every two digitals should be comparted with others by a space character.
DSL Gateway/Router — User Manual 3.5.3 WIRELESS MAC FILTER In fact, the Access List function is just like MAC address filtering and selected to permit or forbid access of wireless station with specified MAC address. Method: select “Allow” or “Deny” mode, and click “Add” button, and input MAC address which you want to allow or deny. Notice: You only can select one of allow mode or deny mode.
DSL Gateway/Router — User Manual 4 OTHER CONFIGURATION 4.1 LAN CONFIGURATION Configuration of Modem’s IP address and password 4.1.1 CONFIGURATION OF MODEM’S IP ADDRESS As a network device, ADSL Modem has its own IP address and MAC address. The factory sets the MODEM, at a default IP address of 192.168.1.1 and subnet mask of 255.255.255.0. The user can configure these addresses through the “LAN” on “Configuration” like this: For example, change IP address to “10.10.10.10”.
DSL Gateway/Router — User Manual 4.1.2 DHCP CONFIGURATION • click“LAN ” • click“DHCP server”； • Define the “Start IP address” and the “End IP address” of DHCP server (for example, from 10.10.10.11 to 10.10.10.254). • Input the value of lease (Measured by the second, 0 indicates permanently valid). As Figure 4.2, open DHCP server, computer will set the IP Address of network card with one of the address 10.10.10.11 ～ 10.10.10.254. Figure 4.
