1 OVERVIEW
1.1 ABOUT WIRELESS 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 (24Mbps for ADSL2+). ADSL is an ideal
device for broadband access.
But the ADSL users are also limited by the cable and can’t move freely. Wireless ADSL is a new device
that integrates WLAN and ADSL functions. User can slip the leash to visit Internet expediently as long as they
install WLAN card into their computer. The device can be utilized in company, hotel, cafe, airport, station, and
financial institution and home where there are many mobile users and the network infrastructures are difficult to
establish. The wireless ADSL supports 802.11b, 802.11b+ and 802.11g mode with maximum data rate 54Mbps.
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 G.992.3(ADSL2),
ITU G.992.5(ADSL2+).
2. Support data transportation among ADSL, Ethernet and WLAN
3. Support 802.11b, 802.11b+ and 802.11g mode
4. Web-based configuration and monitoring.
5. Support up to 8 PVCs.
6. Routing function.
7. Support NAT, DHCP.
8. Maximum downstream transmission rates of 8 Mbps (24Mbps for ADSL2+).
9. Maximum upstream transmission rates of 1Mbps.
10. Transmission distance up to 5.5 km.
11. Wireless access distance is more than 100m

3.4 CONNECTION SETUP
Before the Gateway will pass any data between the LAN interface(s) and the WAN interface, the WAN
side of the modem must be configured. Depending upon your DSL service provider or your ISP, you will need
some (or all) of the information outlined below before you can properly configure the WAN:
1. Your DSL line VPI and VCI
2. Your DSL encapsulation type and multiplexing
For PPPoA or PPPoE users, you also need these values from your ISP:
Your username and password
For RFC 1483 users, you may need these values from your ISP:
1. Your DSL fixed Internet IP address
2. Your Subnet mask
3. Your Default Gateway
4. Your primary DNS IP address
Since multiple users can use the Gateway, the Gateway can simultaneously support multiple connection
types; hence, the user must set up different profiles for each connection. The Gateway supports the following
protocols:
1. DHCP

Atrie DB-120 WL User Manual
Page 9 / 25
2. RFC 2364 PPPoA
3. RFC 2516 PPPoE
4. Static
5. Bridged
6. CLIP
3.4.1 NEW CONNECTION
A new connection is basically a virtual connection. Your Gateway can support up to 8 different (unique)
virtual connections. If you have multiple different virtual connections, you man need to utilize the static and
dynamic routing capabilities of the modem to pass data correctly.
3.4.2 BRIDGE GATEWAY PROFILE AND CONNECTION
A pure bridged connection does not assign and IP address to the WAN interface. NAT and firewall rules
are not enabled. This connection method makes the router act as a hub, and just passes packets across the
WAN interface to the LAN interface.
To configure the Gateway as a bridge, click on "New Connection". At the Type field select Bridge and
the Bridge connection setup page is displayed (Figure 3.2). Give your Bridge connection a unique name; the
name must not have spaces and cannot begin with numbers. In this case the unique name is called bridge1.
Select the encapsulation type (LLC or VC); if you are not sure just use the default mode. Select the VPI and
VCI settings; your DSL service provider or your ISP will supply these; in this case the DSL service provider is
using 0,35.
Figure 3.2 (Bridge Connection Setup)
3.4.3 PPPOA CONNECTION SETUP
PPPoA is also known as RFC 2364. It is a method of encapsulating PPP packets over ATM cells, which
are carried over the DSL line. PPP or Point-to-Point protocol is a method of establishing a network connection
/ session between network hosts. It usually provides a mechanism of authenticating users. LLC and VC are
two different methods of encapsulating the PPP packet. Contact your ISP to make sure which encapsulation is
being supported.
By selecting PPPoA, you are forcing your Gateway to terminate the PPPoA connection. The advantage is
that the PPPoA termination is done within the Gateway and not on your PC; this frees up your PC resources and
allows multiple users to utilize the PPPoA connection.
To configure the Gateway for PPPoA, click on Setup and then click on New Connection. At the Type
field select PPPoA and the PPPoA connection setup page is displayed; Figure 3.3 illustrates a typical PPPoA

with numbers. In this case the unique name is called PPPOA1. Select the encapsulation type (LLC or VC);
if you are not sure just use the default mode. Select the VPI and VCI settings; your DSL service provider or
your ISP will supply these; in this case the DSL service provider is using 0,40.
Following is a description of the different options:
1. Username: The username for the PPPoA access; this is provided by your DSL service provider or
your ISP.
2. Password: The password for the PPPoA access; this is provided by your DSL service provider or your
ISP.
3. On-Demand: Enables on-demand mode. The connection will disconnect if no activity is detected after
the specified idle timeout value.
4. Idle Timeout: Specifies that PPPoA connection should disconnect if the link has no activity detected
for n seconds. This field is used in conjunction with the On-Demand feature. To ensure that the
link is always active, enter a 0 in this field.
5. Keep Alive: When on-demand option is not enable, this value specifies the time to wait without being
connected to your provider before terminating the connection. To ensure that the link is always
active, enter a 0 in this field.
6. MRU: Maximum Receive Unit the DSL connection can receive. It is a negotiated value that asks
the provider to send packets of no more than n bytes. The maximum specified value is 1500
although some DSL/ISP providers require a larger value. The minimum MRU value is 128.
7. Debug: Enables PPPoA connection debugging facilities. Only for supporter.

3.4.5 DHCP CONNECTION SETUP
Dynamic Host Configuration Protocol (DHCP) allows the Gateway to automatically obtain the IP address
from the server. This option is commonly used in situations where IP is dynamically assigned and is not
known prior to assignment.
To configure the Gateway for a DHCP connection, click on Setup and then click on New Connection. At
the Type field select DHCP and the DHCP connection setup page is displayed; Figure 3.5 illustrates a typical
DHCP configuration. Give your DHCP connection a unique name; the name must not have spaces and cannot
begin with numbers. In this case the unique name is called DHCP1. Select the encapsulation type (LLC or
VC); if you are not sure just use the default mode. Select the VPI and VCI settings; your DSL service provider
or your ISP will supply these; in this case the DSL service provider is using 0,35.
If your DSL line is connected and your DSL/IPS provider is supporting DHCP, you can click the renew
button and the Gateway will retrieve an IP address, Subnet mask, and Gateway address. At anytime, you can
renew the DHCP address by clicking on the renew button; in most cases you will never have to use this button.
Figure 3.5 (DHCP Connection Setup)
3.4.6 STATIC CONNECTION SETUP
Static is used whenever a known static IP is assigned. The accompanying information such as the Subnet
mask and the Gateway should also be specified. Up to three Domain Name Server (DNS) addresses can also
be specified. These servers would enable you to have access to other web servers. Valid IP addresses range
is from 0.0.0.0 to 255.255.255.255.
To configure the Gateway for a Static connection, click on Setup and then click on New Connection. At
the Type field select Static and the Static connection setup page is displayed; figure 8 illustrates a typical Static
configuration. Give your Static connection a unique name; the name must not have spaces and cannot begin
with numbers. In this case the unique name is called STATIC1. Select the encapsulation type (LLC or VC);
if you are not sure just use the default mode. Select the VPI and VCI settings; your DSL service provider or
your ISP will supply these; in this case the DSL service provider is using 0,35. You can also enable Network
Address Translation (NAT) and the Firewall options. If you are unsure, leave these in the default mode.
Based upon the information your DSL/ISP provided, enter your assigned IP address, Subnet mask, Default
Gateway (if provided), and Domain Name Services (DNS) values (if provided). For the static configuration,
you can also select a bridge connection or a routed connection. Since static IP address is typically used to host
WEB servers, you may want to use a bridge connection.

4 OTHER CONFIGURATION
4.1 LAN CONFIGURATION
4.1.1 CONFIGUR GATEWAY’S IP ADDRESS
As a network device, the Gateway has its own IP 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 they in "LAN Setup".
For example, to change IP address to "10.10.10.10". Click "LAN Setup", choice "Use the following
Static IP address", then input "10.10.10.10" in "IP address" and "255.0.0.0" in "subnet mask". The result is
shown as Figure4.1, press "Apply".
Figure 4.1
Notes: When the IP address have be changed, it will take effect immediately. Then you maybe cannot access
the WEB-UI.
Please wait about 30 seconds, and then access the WEB-UI by the new IP address.
4.1.2 DHCP CONFIGURATION
The user can configure the DHCP mode in "LAN Setup".
1. To Enable the DCHP Server mode, choice "Enable DHCP Server" and fill in the following textbox.
The "Start IP" is where the DHCP server starts issuing IP addresses. This value must be greater than the
Gateway’s IP address value. For example if the Gateways IP address is 192.168.1.1 (default) than the starting
IP address must be 192.168.1.2 (or higher).
The "End IP" is where the DHCP server stops issuing IP addresses. The ending address cannot exceed a
subnet limit of 254. Hence the max value for our default Gateway is 192.168.1.254. If the DHCP server runs
out of DHCP addresses, users will not get access to network resources. If this happens you can increase the
Ending IP address (to the limit of 255) or reduce the lease time.
The "Lease Time" is the amount of time a network user will be allowed connection to the Router with their
