1. Introduction
1-1. Product Overview
D-Link®, an industry leader in networking, introduces DVG-5121SP VoIP telephone adapter for
the h ome envir onment. The DVG-5121SP VoIP Telephone Adapter converts any existin g analog
(cord or cordless) telephone into an IP Phone. Also by plugging in a FAX machine, the
DVG-5121SP will enable users to send and receive fax the same way as a traditional analog
telephone line.
The DVG-5121SP carries both voice and facsimile over the IP network. It supports SIP industry
standard call control protocol and is compatible with free registration services or VoIP service
providers’ systems. It also supports the most popular audio CODECs to ensure compatibility
and voice quality.
The DVG-5121SP provides two FXS port to connect to two analog telephone sets, PSTN lifeline
port to connect to the phone line, one Fast Ethernet (10/100) port to connect to the VoIP
telephone adapter and another LAN port which allow another computer to be connected by wire.
VoIP service providers can con gure service settings such as a server address, CODEC and
STUN s ettings via TF T P directly t o the DVG-5121SP.
For security, all of the con guration settings are encrypted. Only the VoIP service
providers/resellers with the authenticated password and user name can access them.
The DVG-5121SP fe atures both t he VAD (Voice Act ivity Detect ion) and CNG (Comfort Noise
Generator) to reduce the band width consumption and to sustain voice quality.
The DVG-5121SP has a built-in QoS setting to provide voice priority in IP networks and prevent dropped calls.

Example:
DVG-5121SP connecting directly to phone sets
After connecting telephone sets to P1-P2, users can make direct calls, (P1-P2 are FXS interfaces). Each set
acts as an independent IP line that provided by applied SIP server.

The network settings are used to set the VoIP telephone adapter’s communication ports, IP configurations,
ADSL service setting, IP tunneling and etc. You might refer to the following pages for different WAN settings.
4-1-1. Static IP
Just as each building on a street has an address, so does each computer on the Internet. This "address
scheme" allows you to distinguish between every computer on the Internet. For example, you may have come
across a number in association with Internet lingo such as "198.69.121.3"--or something similar. This is an
Internet Protocol (IP) address.
WAN Port IP Assignment: Select Static if your ISP assigned you a fixed IP address, subnet mask, and DNS server
addresses. Please contact your local Internet Service Provider (ISP) if you have any questions.

4-1-2. DHCP
DHCP stands for "Dynamic Host Configuration Protocol". DHCP's purpose is to enable individual computers on an IP network to
extract their configurations from a server (the 'DHCP server') or servers, in particular, servers that have no exact information
about the individual computers until they request the information. The overall purpose of this is to reduce the work necessary to
administer a large IP network. The most significant piece of information distributed in this manner is the IP address.
WAN Port IP Assignment: Select Dynamic (DHCP, most common) to set user settings of WAN port MAC, WAN
port ping and DNS server
Host Name: The Host Name is optional but may be required by some ISPs. The default host name is the
device name of the Router and may be changed.

adapter. You can use the “Clone MAC Address” button to copy the MAC address of the Ethernet Card installed
by your ISP and replace the WAN MAC address with the MAC address of the router.
Ping from WAN: While enable, it allows end user ping from WAN through internal to check the device working

4-1-3. PPPoE (DSL)
Point to Point Protocol over Ethernet is a proposal specifying how a host personal computer (PC) interacts with
a broadband modem (i.e. xDSL, cable, wireless, etc) to achieve access to the growing number of High speed
data networks. Relying on two widely accepted standards, Ethernet and the point-to-point protocol (PPP), the
PPPoE implementation requires virtually no more knowledge on the part of the end user other than that required
for standard Dial up Internet access. In addition, PPPoE requires no major changes in the operational model for
Internet Service Providers (ISPs) and carriers. The significance of PPP over Ethernet has to do with its far
greater ease of use versus competing approaches. By making high speed access easier to use for end
consumers, and more seamless to integrate into the existing infrastructure for carriers and ISPs, PPPoE could
speed the widespread adoption of High speed access services
WAN Port IP Assignment: Select PPPoE.

PPTP stands for Point to Point Tunneling Protocol. It was developed by a consortium including Microsoft and is
used for establishing VPN (Virtual Private Network) tunnels across the Internet. This allows remote users to
securely and inexpensively access their corporate network from anywhere on the Internet.
PPTP uses a client-server model for establishing VPN connections. Most Microsoft operating systems ship with
a PPTP client, so there is no need to purchase third-party client software. PPTP has the additional advantage
over other VPN technologies of being easy to setup.
