Datasheen D902AC 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.
Datasheen D902AC 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 LINK Yellow, shows DSL line status. DATA Green, Flashing means the Modem is transmitting or receiving data PC Three color, Indicates status of connection to the PC LINE Connected with phone line or “ADSL” port of the splitter.
Datasheen D902AC User Manual 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. 4、 Connect Ethernet port of the ADSL MODEM with 10/100BASE-T port of the computer using the network cable that comes with the modem.
Datasheen D902AC 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.
Datasheen D902AC 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. Totally, this router supports：PPPoA、PPPoE、MER、IPoA、Bridging.
Datasheen D902AC User Manual 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. Figure 3.4 The Modem supports five ADSL protocol modes.
Datasheen D902AC User Manual encapsulation, click “Next” enter to the protocol configure. Below, we introduce the configuraion of the five protocol modes. • PPP over ATM (PPPoA) • MAC Encapsulated Routing (MER) • Bridging • PPP over Ethernet (PPPoE) • IP over ATM (IPoA) 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.
Datasheen D902AC User Manual Figure 3.6 Note：When you use bridge mode, please close “DHCP SERVER”, the result as Figure 3.7 Figure 3.
Datasheen D902AC 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.
Datasheen D902AC User Manual 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.
Datasheen D902AC 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”. Click ”LAN”, input “IP address”: 10.
Datasheen D902AC User Manual • 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 4.2 Note：When you use the DHCP Server, please pay attention to having multi-DHCP Server in one LAN. 4.
