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. It supports upload transmission speed up to
1Mbps and download speed up to 8 Mbps. ADSL is an ideal device for broadband access.
But the ADSL users are also limited by the wire and can’t move freely. DB108-WL wireless ADSL Modem is
a new device that integrates WLAN and ADSL functions. Users can slip the leash to visit Internet even in moving
as long as they install WLAN cards into their computers. DB108-WL can be utilized in companies, hotels, cafés,
airports, stations, financial institution and personal homes where there are many mobile users and the network
infrastructures are difficult to establish. The wireless data rate varies among 1, 2, 5.5 and 11Mbps.

Not only can the DB108-WL be used as an ADSL Modem, it also has routing, DHCP and DNS features,
which are especially applicable for small LAN such as cyber cafés and/or small companies.
When DB108-WL is used in LAN, the connection is shown as Figure 4.1
Figure4.1
Router and proxy server are not always necessary in the LAN. You can use DB108-WL as the router, and
DHCP, DNS as the server. The configuration is as follows:
4.1 TCP/IP PROTOCOL CONFIGURATION
1. Set IP address as “Automatically obtain IP address”
2. Set gateway same as IP of DB108-WL
3. Set DNS’s address at DB108-WL’s IP address or validated DNS address
4.2 DB108-WL SETTINGS
1. Set protocol referring to chapter 3
2. DHCP server settings
Using DB108-WL you can dynamically manage up to 253 IP addresses, as described below.
zSelect“DHCP SERVER”
zSet “DHCP address pool selection” to “user defined”
zDefine the “Start IP address” and the “End IP address” of DHCP server (for example, from 192.168.1.2
to 192.168.1.254).
zInput the value of lease (Measure by the second, zero indicates permanently valid)
