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.
