D-Link®, an industry leader in networking, introduces DVG-2001S VoIP Telephone Terminal
Adapter for the home environment. The DVG-2001S converts any existing analog (cord or
cordless) telephone into an IP Phone. Also by plugging in a FAX machine, the DVG-2001S
will enable users to send and receive fax the same way as a traditional analog telephone
line.
The DVG-2001S supports the SIP protocol, which is the widely deployed by VoIP providers
on the market. It also supports the most popular audio CODECs to ensure compatibility
and voice quality.
The DVG-2001S comes with one FXS port to connect to the existing analog telephone and
one Fast Ethernet (10/100) port to connect to the broadband router.
With a built-in secured provisioning feature, VoIP service providers can configure service
settings such as a server address, CODEC and STUN settings via HTTPS/TFTP directly
to the DVG-2001S.
For additional security, all of the configuration settings are encrypted. Only the VoIP service
providers/resellers with the authenticated password and user name can access it.
The DVG-2001S features both the VAD (Voice Activity Detection) and CNG (Comfort Noise
Consumption) to reduce the bandwidth consumption and to sustain voice quality.
The DVG-2001S has a built-in QoS setting to provide voice priority in IP networks and
prevent dropped calls. By delivering a consistent quality of service, resellers will avoid having
frustrated customers from switching to another VoIP service provider.
The DVG-2001S is the ideal VoIP adapter solution that will help VoIP service providers or
resellers with all of the required attributes to grow and retain customers by delivering a robust
and consistent VoIP solution.

Note: if you have changed the default IP address assigned to the DVG-2001S, make sure
to enter the correct IP address.
Using the Configuration Utility
Open a web browser and type in the
IP address of the DVG-2001S.
Using the Configuration Utility
If you are going to connect the DVG-2001 to a D-Link router using the default LAN IP address
(192.168.0.1), or to an existing network with a network IP of 192.168.0.xxx, plug the DVG-2001
into the router using an Ethernet cable and skip to the last step below. The default IP address of the
DVG-2001 is 192.168.0.80.
If you are setting up the DVG-2001S for the first time, you will need to connect the unit directly
to a computer for configuration.
Insert one end of the Ethernet cable into the Ethernet (LAN) port on the back panel of the
DVG-2001S and the other end of the cable to an Ethernet adapter on your computer.
Connect the power adapter to the power input at the back panel of the VoIP Adapter and
then plug the other end of the power adapter to a wall outlet or power strip. On the front of
the device, the Power LED will turn ON to indicate proper operation.
Windows 2000/XP: Go to Start > right-click My Network Places > select Properties >
Right-click Local Area Connection > select Properties > double-click Internet Protocol
(TCP/IP). Remember your original settings since
you will change them back when completing the
configuration.
Set your PC’s IP address to 192.168.0.2

DSCP (Differentiated Services Code Point) is an integer value
encoded in the DS field of an IP header. The DSCP is an example of
traffic marking because its value corresponds with a preferred QoS
as the packet traverses the network. The DSCP value corresponds
to a specific QoS.
Differentiated Services (DS) is an approach to providing quality of
service in networks; it employs a small, well-defined set of building
blocks from which a variety of aggregate behaviors may be built. A
short bit pattern in each packet, in the IPv4 Type of Service (now
called the DS octet) byte or the IPv6 Traffic Class byte, is used
to mark a packet to receive a particular forwarding treatment, or
per-hop behavior, at each network node. DS is thought to provide a
scalable way of implementing layer 3 services because the requisite
actions are distributed throughout the network without the need for
networkwide state machines.
Real-Time Transport Protocol. RTP is designed to provide end-to-end
network transport functions for applications transmitting real-time
data, such as audio, video, or simulation data, over multicast or
unicast network services. RTP provides services such as payload
type identification, sequence numbering, time-stamping, and delivery
monitoring to real-time applications.
