D-Link DVG 6004S
4/8-Port VoIP Trunk Gateways
The D-Link DVG-6004S/DVG-6008S VoIP trunk gateways connect an IP network to POTS (plain old
telephone service) analog lines to send IP voice and data to the conventional phone sets and fax
machines. Designed as a cost-effective VoIP solution for a small to medium-sized business and the
branch office, these devices provide 4 or 8 FXO (Foreign eXchange Office) ports for 4 or 8 phone line
connections. IP network connection can be through any of the 4 LAN ports or the WAN port (all
10/100BASE-TX Ethernet interfaces).
For Office Use. In a remote IP phone to local analog phone line application, a branch office can take in IP
voice calls from a head office, then route them to local destinations equipped with only analog phones.
The long distance calls are sent through the Internet without any phone charge, and the remote office
pays only for the local analog phone time. The gateways connect analog callers to the IP network without
involving operators or incurring toll charges from telephone companies.
The DVG-6004S/DVG-6008S VoIP gateways can be deployed to interface VoIP infrastructure with a
Public Switched Telephone Network (PSTN). They allow analog phone callers to place calls through the
long-distance Internet trunk line. The gateways accept dial tone and ring current from the connected
equipment, and facilitate the use of conventional phone sets and fax machines on a VoIP network.
Guaranteed Voice Quality. The DVG-6004S/DVG-6008S gateways deliver clear sound, voice and reliable
fax calling through implementation of internationally recognized standards for voice and data networking.
They incorporate Quality of Service (QoS) functions to ensure that voice received through the Internet is
the same as or even surpasses that received on the ordinary phone.
Convenient Call Features. The DVG-6004S/DVG-6008S gateways support extensive call features,
allowing the service providers to offer these functions to their subscribers. Provided that the telephone
sets at the end-users side support these functions, callers can take advantage of these convenient
features. Configuration of individual phone connection is easy, using the multi-language Interactive Voice
Response (IVR) or the web-based user's interface.
Shared Broadband Internet Connection/Integrated 4-Port Switch. The gateways provide a convenient
router function to permit office users to share the Internet broadband line. With 4 integrated Ethernet ports,
office computers can readily connect to these gateways and use their built-in NAT/DHCP server functions
for automatic logon to the Internet.
