Introduction
TheD-LinkDG-102SVoIPStationGatewaylinkstraditional telephony networks
to IP networks with conventional telephony devices such as analog phones or
fax machines. The DG-102S includes two loop start Foreign Exchange
Subscriber (FXS) that interfaces with normal RJ-11 telephone connectors to
provide voice/fax communication over the IP network. The DG-102S also
includes two 10/100 Mbps Fast Ethernet ports. One Ethernet port is for a DSL/
CableModemorotherWANdevices,andtheothermayfunctionasa connection
to create a home or small office LAN network. The built-in DHCP server/client
and Network Address Translation (NAT) function automatically to assign IP
addresses for LAN users, allowing multiple users to share a single Internet
connection. It can be configured and monitored via the Console, Web browser,
or Telnet and also supports SNMP management.
By routing calls over the Internet or any IP network, this gateway can reduce or
eliminate long distance or inter-office phone charges. Corporations can also
enjoy the benefits of network consolidation and the reduction of leased lines by
relyingonInternetservice providers todelivertoll-qualityvoice communications
over the IP networks.

Identifying External Components
Front Panel
Understanding Indicators
Before configuring your VoIP Gateway, take a few minutes to look over this
section and familiarize yourself with the front panel LED indicators depicted
below.
Power: This LED is lit when the device is receiving power; otherwise, it
is unlit.
Status: This LED will flash quickly when the DG-102S is either perform-
ing a self test or booting up. The LED will remain lit when the system is
ready for a connection with the call agent. It will remain dark when the
system is ready but can not receive an acknowledgement from the SIP
server.
WAN: This LED displays the connection speed, link status, and activity
on the 10/100 dual-speed Ethernet port that is used to connect to your
WAN device (usually a DSL/cable modem).

Identifying External Components
10/100M: This indicator remains unlit when there is no connection, or
the port is operating at 10Mbps through a connection to a 10BASE-T
device. It is lit when the port is operating at 100Mbps through a con-
nection to a dual-speed or 100BASE-TX Fast Ethernet device.
Link/Act: When a good link to a powered-up, but idle device is de-
tected on a port, this indicator shines steadily. When packets are re-
ceived from the device, the indicator blinks.
Line: Lights when PSTN line is in use.
Phone 1 to 2: Lights when standard phone port is in use.
Note: If a powered-up device is connected to a port and the port’s Link/Act status
indicator is unlit, the most probable cause is a cabling or connection problem
(for example, wrong cable type or bad contact) or a device malfunction.
LAN: ThisLEDdisplaystheconnectionspeed,linkstatus,andactivity on
the 10/100 dual-speed Ethernet port that is used to connect to your LAN.
10/100M: This indicator remains unlit when there is no connection, or
the port is operating at 10Mbps through a connection to a 10BASE-T
device. It is lit when the port is operating at 100Mbps through a con-
nection to a dual-speed or 100BASE-TX Fast Ethernet device.
Link/Act: When a good link to a powered-up, but idle device is de-
tected on a port, this indicator shines steadily. When packets are re-
ceived from the device, the indicator blinks.

Identifying External Components
AC Power Connector: For the included power adapter. Be sure to use
only the 12VDC/1A power adapter included with the product. Using the
wrong power adapter can damage the product and void the warranty.
Diagnostic Port: An RS-232 serial port used to configure the device.
Plug one end of a straight-through wired RS-232 cable to the device and
the other end to a serial port of a PC running a terminal emulation pro-
gram (such as Microsoft HyperTerminal) or a VT-100 terminal.
Fast Ethernet WAN: A10/100dual-speed Ethernetport fitted with an RJ-
45 connector used to connect the VoIP gateway to a WAN device (usually
a router). This port accepts Category 3, 4 or 5 UTP cabling with an RJ-45
connector.

Fast Ethernet LAN: A 10/100 dual-speed Ethernet port fitted with an
RJ-45 connector used to connect the VoIP gateway to a LAN device
(switch, PC, etc.). This port accepts Category 5 or higher UTP cabling
with an RJ-45 connector.
Line: RJ-11 phone jack for connecting to a standard telephone wall out-
let through an approved (No. 26AWG or larger) telecommunications line
cord.
Phone 1 to 2: Normal RJ-11 phone jacks used to connect analog (or
digital) telephones and fax machines. Plug your telephone(s) and/or fax
machine directly into any of these jacks.
Installation
When choosing a place to install the VoIP Gateway, please use the following
guidelines:
The power outlet should be within 1.82 meters (6 feet) of the device.
Visually inspect the power cord and see that it is secured to the AC
power connector.

Connecting the Network Cable
Category 3, 4 or 5 UTP cable can be used to make the Ethernet connection to
your router.
Themaximum cablelength betweenthe DG-102Sand thesupporting callagent
is 100 meters. The cable must be a straight-through (not a crossover cable)
with RJ-45 connectors at each end.
Connecting the VoIP Gateway to a Hub/Switch
Connecting the VoIP Gateway to a Computer
TheDG-102S requiresa straight-throughcable whenconnecting toa computer.
Make sure that your IP address on your Ethernet card is in the same subnet as
the DG-102S otherwise it will not connect.
To connect the device to either a hub or switch, you must connect the straight-
through cable to the LAN port.
Getting Started
Installation
When installing the unit on a desktop or shelf, the rubber feet in-
cluded with the device should be attached. These cushioning feet
should be attached to the bottom corners of the device.
Do not place heavy objects on the DG-102S. Placing the DG-102S in
a well ventilated area is very important. Not doing so may cause
damage to the unit.

Configuration
Configuring the VoIP Gateway
Using a web browser on a computer connected to the device via the
WANor LAN Ethernetconnections. Inthe discussionbelow,the computer
running the browser is referred to as the management station.
Using a terminal or computer running terminal emulation software
connected to the diagnostic port via an RS-232 cable. In the discussion
below, the terminal (or computer) is referred to as a console and the
connection, a console connection.
