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. Th e frequ ency 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、DH CP function.

5. TROUBLESHOOTING

5.1 UNABLE TO ACCESS INTERNET

5.1.1 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 turne d 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 chang e s s tat us to fa st twi nkl in g af ter 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 pro blem in the above items, th e line and the device shall be working. Problems may come
from your computer configuration or device co nfiguration.

5.1.2 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.x

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”.

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

 If ping is reachable, there shall be no problems in the network settings. Please check the settings

 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

without conflict. See 3.2;

of the PC terminal, e.g. whether the security level is too high, or whether anti-virus firewall is
installed;

Page 18 Total 19 Pages

Datasheen D902AW User Manual

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 5.1

6、 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 ex ists, for troubleshooting ,

delete unused connections and rema in 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.
