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.

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”: 10.10.10.10, then “subnet mask”: 255.0.0.0, the result is as Figure4.1, press “save”.

Figure 4.1

Note.If you change IP address, it will take effect after you reboot the modem. You must use the new IP address to login.

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 192.168.1.2 to 192.168.1.254).

• 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.

Note.When you use the DHCP Server, please pay attention to having multi-DHCP Server in one LAN.

4.2 PASSWORD CONFIGURATION

When you configure ADSL MODEM through an Internet browser, the system requires user name and password to validate access permission. The factory sets the modem at a default username of “admin” and the password of “password”. The username is unchanged. You can enter the “password configuration” on Configuration column to change the password.

Attention: please remember the password after change, otherwise you will not be able to change configuration after saving setting.

5 USAGE OF USB INTERFACE

The Combo DSL Gateway is a device with both Ethernet Interface and USB Interface, which is independent, you may use either of them to connect to the different computers, in this way the two computers can connect to the network at one time. The Gateway can be seen as a simple two-port HUB. So, do not connect both the Ethernet Interface and USB Interface to a same computer.

When using USB Interface, you must install the drivers. After installation, a virtual network card, "USB Remote NDIS Network Device", will be added into the computer. It has all the functions of a real network card, and it makes installation more easily.

User can also change its configuration for special reason.

6. Troubleshooting

6.1 unable to access internet

6.1.1 check the line and the device

1、 Check the indicator of power supply is on, if not, Make sure the connection of power supply is correct; Make sure the output of power supply is correct; Make sure the switch of power supply is turned on；

2、 Check the indicator of PC is on, if not, Make sure the connection of cable and network adapter; Make sure that the correct cable is used;

3、 Check the LINK LED to see if it is twinkling. If no fast twinkling is observed within 3 minutes, please check whether phone line has been correctly placed; whether ADSL separator is correctly used. If multiple extensions have been installed, make sure that the separator is installed prior to the junction box of phone line. If the above items are confirmed and still no fast twinkling of WAN LED is observed, call the ISP to query whether ADSL service has been provided on your line;

4、 Check the LINK LED to see whether it is unable to change status from fast twinkling to always light, or whether it changes status to fast twinkling after sometime of always light. If these phenomena occur constantly, please contact your ISP with a demand to check lines and signal quality;

If there is no problem in the above items, the line and the device shall be working. Problems may come from your computer configuration or device configuration.

6.1.2 check your configuration

We explain here the configuration of PPPOE using Windows 2000 operation system as an example. For other operation systems the process is similar.

1. Enter the device manager to check if Ethernet adapter is correctly installed. If any problem exists, please re-installed it;

2. Check the configuration of Ethernet adapter in PC. Try to manually set IP address that is in band 192.168.1.xwithout conflict. See 3.2;

3. Try to run command “ping 192.168.1.1” on command line mode. If the response returns “time out”, please check Ethernet connection and IP settings;

4. If this modem is reachable, try to run ping with a known outer IP, e.g. the DNS server IP of ShangHai Online: “ping 202.96.209.133”.

l If ping is reachable, there shall be no problems in the modem. Please see step 5;

l If ping is not reachable, see step 6 and check if the configuration is correct.

5. Please try to ping a certain outer URL, e.g. “ping www.google.com”.

l If ping is reachable, there shall be no problems in the network settings. Please check the settings of the PC terminal, e.g. whether the security level is too high, or whether anti-virus firewall is installed;

l If ping is not reachable, check the DNS setting of Ethernet adapter. See 3.2.

Note 1.The precondition is that LAN settings in the modem has not been modified.

Note 2.We usually start command line mode in Windows 2000 as follows: click on the “RUN” item of Windows Start Menu, input characters “cmd” in the input box popped up with an “Enter”. The window subsequently popped up is the command line window.

Note 3.The returned values of ping command in the following format show the standard of “reachable”

Figure 6.1

1. If ping of the modem is reachable but ping of the outer fixed IP is unreachable, attention should be concentrated upon device settings. Please enter the configuring interface following the instructions in this manual.

1 Check first the number of connections. If more than one connection exists, for troubleshooting , delete unused connections and remain the one connection you are using.

2. Check the connection to see whether correct “type” is selected. It’s normal to choose login type of PPPoE. When you use PPPoE to login, the following information should be provided: VPI and VCI, which can be queried from your ISP, user name and password.

3. Then make sure that “using NAT” and “default gateway” have been selected with a tick. Check whether “connect on demand” has been selected with a tick. If it is selected, the connection is activated only when traffic to outer networks arrives. If not selected, check “keep connection”, which should be set to 0 if you demand to keep connection

Make sure that the above parameters are saved after configuration. Internet is now available since the configuration is properly done.
