Introduction
Thank you for choosing the D-Link DG-104SH, the value leader for VoIP products.
The D-Link DG-104SH VoIP Station Gateway links traditional telephony networks to IP networks with
conventional telephony devices such as analog phones or fax machines. The DG-104SH includes four loop start
Foreign Exchange Subscriber (FXS) interfaces with normal RJ-11 telephone connectors that provide voice/fax
communication over the IP network,and it also provide two 10/100 Mbps dual speed Ethernet ports. One Ethernet
port is for a DSL/Cable Modem or other WAN devices, and the other is for connection to create a home or small
office LAN networks. The built-in DHCP server/client and Network Address Translation (NAT) function
automatically assign IP address for LAN users, allowing multiple users to share a single Internet connection. It
can be configured/monitored via the Console, Web browser or Telnet and SNMP management is also supported.
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 reduction of leased lines
by relying on the Internet service providers to deliver toll-quality voice communications over the IP networks.

♦Phone 1 to 4Normal RJ-11 phone jacks used to connect telephones and fax machines. Plug your normal
telephone(s) and/or fax machine directly into any of these jacks.
Physical Installation
Use the following guidelines when choosing a place to install the VoIP Gateway:
♦The surface must support at least 1 kg.
♦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.
♦Make sure that there is proper heat dissipation from and adequate ventilation around the device. Do not
place heavy objects on the unit.
When installing the unit on a desktop or shelf, the rubber feet included with the device should first be attached.
Attach these cushioning feet on the bottom at each corner of the device. Allow adequate space for ventilation
between the device and the objects around it.
Connecting the Network Cable
Category 3, 4 or 5 UTP cable can be used to make the Ethernet connection to your WAN router.
The maximum cable run between the DG-104SH and the supporting call agent is 100 meters. The cable must be
straight (not a crossover cable) with RJ-45 connectors at each end. Make the network connection by plugging one
end of the cable into the RJ-45 jack of the DG-104SH, and the other end into a port on your WAN router.
Connecting the VoIP Gateway to a PC
Once the device has been connected to a PC, you will need a separate IP address and a straight cable.

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.
♦Test This LED will flash quickly when the CPE is either performing a self test or booting up. The LED will
remain lit when the system is ready for a connection with the Gatekeeper; it will remain dark when the
system is ready but can not receive an acknowledgement from the Gatekeeper.
♦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 router).
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
connection to a dual-speed or 100BASE-TX Fast Ethernet device.
Link/Act −When a good link to a powered-up but idle device is detected on a port, this indicator shines
steadily. When packets are received from the device, the indicator blinks off and on.
♦LAN 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 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
connection to a dual-speed or 100BASE-TX Fast Ethernet device.
Link/Act −When a good link to a powered-up but idle device is detected on a port, this indicator shines
steadily. When packets are received from the device, the indicator blinks off and on.
♦Phone 1 to 4 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.

Configuration
In order to use the DG-104SH VoIP gateway, you must first configure it.
Configuring the VoIP Gateway
There are two ways to configure the VoIP gateway, both of which are discussed below. They are:
♦Using a terminal or PC running terminal emulation software connected to the diagnostic port via an RS-232
cable. In the discussion below, the terminal (or PC) is referred to as a console and the connection a console
connection.
♦Using a web browser on a PC connected to the device via the WAN or LAN Ethernet connections. In the
discussion below, the PC running the browser is referred to as the management station.
Configuring the VoIP Gateway using a Console
Setting Up a Console
First-time configuration must be carried out through a "console," that is, either (a) a VT100-type serial data
terminal, or (b) a computer running communications software set to emulate a VT100. The console must be
connected to the Diagnostics port. This is an RS-232 port with a 9-socket D-shell connector and DCE-type
wiring. Make the connection as follows:
1. Obtain suitable cabling for the connection.
You can use either (a) a "null-modem" RS-232 cable or (b) an ordinary RS-232 cable and a null-modem
adapter. One end of the cable (or cable/adapter combination) must have a 9-pin D-shell connector suitable
for the Diagnostics port; the other end must have a connector suitable for the console's serial
communications port.
2. Power down the devices, attach the cable (or cable/adapter combination) to the correct ports, and restore
power.
3. Set the console to use the following communication parameters for your terminal:
♦9600 baud
♦VT-100/ANSI compatible
♦No parity checking (sometimes referred to as "no parity")
♦8 data bits (sometimes called a "word length" of 8 bits)
♦1 stop bit (sometimes referred to as a 1-bit stop interval)
♦No Flow control
♦VT-100/ANSI compatible
♦<Tab> keys enabled
A typical console connection is illustrated below:

DG-104SH VoIP Station Gateway
Example of a Console Connection
Configuring the VoIP Gateway Using Telnet
Once you have set an IP address for your device, you can use a Telnet program (in a VT-100 compatible
terminal mode) to access and configure it. Most of the screens are identical, whether accessed from the console
port or from a Telnet interface.
Console Usage Conventions
The console interface makes use of the following conventions:
Items in <angle brackets>can be toggled on or off using the space bar.
Items in [square brackets] can be changed by typing in a new value. You can use the Backspace and Delete
keys to erase characters behind and in front of the cursor.
The <Tab>key and the Backspace key can be used to move between selected items. It is recommended that you
use the <Tab>key and Backspace key for moving around the console.
Items in UPPERCASE are commands. Moving the selection to a command and pressing Enter will execute that
command, e.g. APPLY, etc.
Please note that the command APPLY only applies for the current session. Use Save Changes from the
Main Menu for permanent changes.
