Introduction
TheD-LinkDVG-1120SVoIPStationGatewaylinkstraditionaltelephonenetworks
to IP networks with conventional telephone devices such as analog phones or
fax machines.
The DVG-1120S 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-
1120S via the Console or the Web browser. Telnet and SNMP management is
also supported.
Byroutingcalls over the Internetorany IPnetwork, the DVG-1120S can reduce
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.

Web-based Management (continued)
1. A full telephone number, e.g., 555-5555: The system will transmit
the number to the non-default line, when the user’s first dialed digits
match the number.
2. Any combination of a telephone number and “x” character. “x”
means any one digit, e.g. 55xx: The System will transmit all of the
numbers with the same first two digits to the non-default line. (Ex:
5511, 5594,…etc.)
3. Any combination of a telephone number and “T” character. “T”
must be capital and it means a random number, e.g., 55T. The
system will transmit all of the numbers that begin with 55 to the non-
default line (Ex: 553-5551, 557-5555…etc.)
Del Digit - Enter the number of digits that will be deleted from the front of the
number when the system transmits the number above. (Ex: The number is
505-555-5555, Del Digit is 3. System will only transmit 555-5555.)
Click on the Save button at the bottom right of the window to save the settings.
Another way to access the non-default line is to input a prefix when dialing.
Whenever you use a prefix (Ex: “#”, “*,” or “0000,” ...etc.), the system will
automatically revert to the non-default line.
