Introduction
TheD-LinkDVG-1120MVoIPStationGatewaylinkstraditionaltelephonenetworks
to IP networks with conventional telephone devices such as analog phones or
fax machines.
The DVG-1120M includes two Foreign Exchange Subscriber (FXS) interfaces
with normal RJ-11 telephone connectors that provide voice/fax communication
over the IP network.
Two Ethernet ports are also provided. One Ethernet port is for a DSL/Cable
Modem or other WAN device, and the other is for connection to create a home
or small office LAN network.
The built-in DHCP server and Network Address Translation (NAT) function
automatically assigns IP addresses for LAN users, allowing multiple users to
share a single Internet connection. You can configure and monitor the DVG-
1120M via the Webbrowser.Telnet andSNMPmanagement is also supported.
Byroutingcalls overtheInternet or anyIPnetwork, the DVG-1120M canreduce
or eliminate long distance or inter-office phone charges. Corporations can also
enjoy the benefits of network consolidation and reduction of leased lines by
relying on the Internet service providers to deliver toll-quality voice
communications over the IP networks.

LEDS
Ethernet - This LED displays the
connection speed, link status, and
activity on the 10/100 dual-speed
Ethernet port that is used to connect
toyourLAN.
10/100M - This indicator remains
unlit when there is no connection,
or the port is operating at 10Mbps
throughaconnectiontoa10BASE-
T device. It is lit when the port is
operating at 100Mbps through a
connection to a dual-speed or
100BASE-TX Fast Ethernet
device.
Link/Act - When a good link to a
powered-up but idle device is
detected on a port, this indicator
shines steadily. When packets are
received from the device, the
indicator blinks off and on.
WAN This LED displays the
link status and activity on the
10MEthernetportthatisused
to connect to your WAN
device (usually a Cable or
ADSLModem).When agood
link to a powered-up but idle
device is detected on a port,
the WAN indicator shines
steadily. When packets are
received from the device, the
indicator blinks off and on.
Phone 1 - ThisLEDdisplays the
activity on the RJ-11 port that is
used to connect to your normal
telephone/faxmachineline.
Power This LED is lit when
the device is receiving
power; otherwise, it is unlit.
Status/Alarm
This LED will remain green when the
CPE is either performing a self-test or
booting up. The LED will flash green
slowly when the system is ready for a
connection with the CallAgent. It will
remain red when the self-test or
booting up is failed. It will flash red
slowly when the system is ready but
cannot receive an acknowledgment
from the CallAgent.
Hook/Ringing - When an off-
hook action is detected on a
phoneport,thisindicatorshines
steadily. When a ringing signal
isreceived from thedevice, the
indicator blinks off and on.

Web-based Management
In order to use a web browser to configure the VoIP gateway, you must make
sure it has a valid Ethernet connection to a PC or LAN via its LAN port.
Accessthe configurationutilityto checkthe LANport byentering theIPAddress
into your web browser address field.
Click on Login to the
Web-based

Setting Up the Connection
TheVoIPgateway’s WANportcomes
withDHCP asdefaultIPsetting.Ifthe
VoIP gateway cannot get the
assigned DHCP IP, it will use the
manual IP (default is 10.1.10.5 ) as
it’s default IP.
Click on Configure WAN Port.
To configure theWAN port, please dothefollowing:
Then go to Start>Control
Panel>Network
Connections>Right-click local
area connection >select
Properties> double click Internet
Protocol (TCP/IP). The screen at
right will appear.
Make sure the PC is in the same IP
domain as the VoIP gateway. You
can do this by changing the IP
address of the PC as shown here.
Manually input the
WAN IPAddress here.

Web-based Management (continued)
To configure the LAN port for the device, please do
thefollowing:
After you have configured your WAN and LAN ports you can click on Save

configure the VoIP.After you have completed configuring the VoIP, you must
Save and Restart the System or your changes will not be saved.
In this configuration menu, users can configure the LAN IPAddress.
(Recommended for advanced users.)
By default the LAN IPAddress is: 192.168.15.1

Start IP Address -This is the base (starting) address for the IP pool of
unassigned IP addresses.
IP Range - This is the range of contiguous, IP addresses above the base IP
Address above.
Netmask - This mask informs the client, how the destination IP address is to
be divided into network, subnet, and host parts. The netmask has ones in the
bit positions in the 32-bit address which are to be used for the network and
subnet parts, and zeros for the host part.
Leased Time - This specifies the amount of time (in seconds) a client can
lease an IP address, from the dynamically allocated IP pool.
DNS Server IP - This specifies the Domain Name System server, used by the
DHCP clients using leased IP addresses, to translate hostnames into IP
addresses or vice-versa.
WIN Server IP - Some LANs may require using WINS servers; enter the IP
address of the WINS server or leave blank.
Domain Name - Enter a domain name for the network group or leave blank.
