Introduction
The D-LINK DVG-2101S VoIP Telephone Adapter links conventional telephony
devices such as analog phones or fax machines to IP networks. The DVG-
2101S includes one Ethernet port and one RJ-11 telephone jack that provide
voice communication over the IP network. The Ethernet port is for a DSL/Cable
Modem or other WAN (Wide Area Network) devices. It can be configured and
monitored using a web browser.
This VoIP Telephone Adapter can reduce or eliminate long distance or inter-
office phone charges by routing calls over the Internet or any IP network.
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.

Hardware Installation
Connecting the DVG-2101S Directly to a Modem
If your computer connects directly to a DSL or Cable modem and does not
connect to a router, follow the steps below to install your DVG-2101S.
Note: This is the most common setup configuration for the DVG-2101S. If you
do not require the use of more than one LAN port, you do not need an
additional router.
1. Turn off your computer.
2. Disconnect the power to your Cable/DSL modem (unplug or turn off the
power switch).
3. Unpack the Ethernet cable (blue) that comes with DVG-2101S. Attach one
end of the Ethernet cable (blue) provided in this package to a LAN or
Ethernet port on your Cable/DSL modem. If there are no Ethernet ports
available on your modem, you should include a router in your network setup
(see diagram on the next page).
4. Attach the other end of the provided Ethernet cable to the WAN port of the
DVG-2101S.
5. Attach one end of the provided phone cable (gray) to a standard analog
telephone.
6. Attach the other end of the phone cable to the PHONE port on the rear
panel of the DVG-2101S.
7. Reconnect the power to the Cable/DSL Modem (plug in or turn on the power
switch).
8. Unpack the 12V DC power adapter that comes with the DVG-2101S.
Connect the power adapter to the power connecter on the DVG-2101S.
9. Connect the other end of the power adapter to an available electrical outlet
(wall socket or surge protector).
10.Restart your PC.

Connecting the DVG-2101S Behind a Router
If you wish to connect your DVG-2101S behind a router, follow the steps below.
After the steps are completed, your setup should look similar to the diagram
below.

5. Attach one end of this Ethernet cable to the WAN port on the rear of the
DVG-2101S.
6. Attach the other end of this Ethernet cable to a LAN port on your existing
router.
7. Be sure that the Ethernet cable that is plugged into the WAN port of your
existing router is still plugged into your Cable/DSL Modem.
8. Unpack the phone cable (gray) that came with the DVG-2101S. Attach one
end of this cable to a standard analog telephone.
9. Attach the other end of this cable to the PHONE port on the rear of the
DVG-2101S.

By default the unit is already configured to work behind a router. Be sure to
change your computer’s IP settings to DHCP (to automatically be assigned an
IP address from the DVG-2101S) regardless of what type of Internet connection
you have. (Please refer to your Network Interface Card’s manual for more
detailed information.)

Configuration
Prior to using your web browser for accessing the web-based configuration
utility, if DHCP is not enabled on your computer, be sure to assign a static IP
address to the VoIP Telephone Adapter.
Use the computer that was last connected directly to your Cable/DSL modem.
Right-click My Network Places > select Properties > right-click Local Area
Connection > select Properties > double-click Internet Protocol (TCP/IP).
In order to use a web browser to configure the VoIP Adapter you must make
sure it has a valid Ethernet connection to a PC or LAN via its LAN port. Access
the configuration utility to check the LAN port by entering the IP Address into
your web browser address field.
Set your PC’s IP address to
192.168.1.1 and the subnet
mask to 255.255.255.0. The
default gateway and primary
DNS server IP addresses
should be the LAN IP
address of the DVG-2101S
(192.168.1.150).
Open a web browser and type
http://192.168.1.150 into the
URL address box. Press the
Enter or Return key.
Click OK.

MTU Enter the MTU (Maximum Transmission Unit) size. MTU is the
largest size packet that can be sent by the device. If the network
stack of any packet is larger than the MTU value, then the packet
will be fragmented before the transmission. During the PPP
negotiation, the peer of the PPP connection will indicate its MTU
and will accept any value up to that size.
