Introduction of ADSLIntroduction of ADSL FeaturesFeatures

l Using the existing copper twisted-pair (2 wires),subscriber can use fast Internet access and POTS

simultaneously.

l Asymmetrical Transmission : downstream rate is much

higher than upstream rate, its the better condition formost of the Internet applications

l Max. Downstream : 8Mbps, Max. Upstream : 1Mbps; its

used for dedicated line but cable modem is the sharing

bus architecturel Always On-line

l Configure IP Address of Your Computern Before you can configure this ADSL Router. You need

first to configure the IP address of your Computer to

be within the same subnet as the ADSL Router.

n The default management IP address of the ADSLRouter is 192.168.1.1. For example, you can set the IP

address of your computer to 192.168.1.2

Troubleshooting (I)Troubleshooting (I)

l The power (PWR) LED is off.n Make sure ATU-R is connected to the power adapter and

the power adapter is plugged into a wall outlet.

l The WAN Link (WLK) LED is off.

n After 1 minute, ATU-R should be ready and WLK LEDshould be on. If we do not see the WLK LED on then power

cycle the ATU-R by turning the power switch off and on

again.

well established.

n The VPI or VCI is incorrect.

n The protocol type is not the same such as PPP, 1483 LLCmode.

n Inappropriate IP specification on WAN IP address.

n Username or password is incorrect under PPP connection.

l How do I verify my PCs IP address which isassigned by ATU-R router?n Make sure you power on ATU-R. After the PC starts, select

from the Windows Start menu. Enter winipcfg and

click to show the TCP/IP configuration of your PC.Check for appropriate Ethernet cabling if the IP Address

tool bar still indicates .

Troubleshooting (IV)Troubleshooting (IV)

l I cannot access the Internetn Check if the ATU-R router is powered on.

n Examine if ATU-R WLK" LED is on.

If not, check ADSL line connection from the wall.

n

Check if the all setup is correct.n If the whole configuration is OK, try powering off /on the

ATU-R again to activate new setup profile.

l I can not surf WEB or browser says the serverdoes not have a DNS entry.n Please examine the DNS server address available on the ISP

setup table.

l I can not enter web to do configuration.n Please wait for the booting procedure has been done

because ATU-R is in initialization phase after this program.
