Thank you for choosing the D-Link DG-102SH, the value leader for VoIP products.
The D-Link DG-102SH VoIP Station Gateway links traditional telephony networks to IP networks with
conventional telephony devices such as analog phones or fax machines. The DG-102SH includes two 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.

%& """#
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.
#&'#("
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-102SH 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-102SH, and the other end into a port on your WAN router.

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 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.
♦ 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.

In order to use the DG-102SH VoIP gateway, you must first configure it.
#&)#%*'
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.
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
♦ Arrow keys enabled
A typical console connection is illustrated below:
DG-102SH VoIP Station Gateway

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.
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 up and down arrow keys, the left and right arrow keys, 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.
First make the console connection to the device and then power it on. If your terminal (or terminal emulation
program) is properly configured according to the specifications defined above, you will see the POST test and
the boot up process. During this process, press <Ctrl+C> to reach the Boot Menu (shown below).

If the boot up process has proceeded too far and you did not reach the Boot Menu shown above, unplug the device,
plug it back in (to restart the boot up process), and press <Ctrl+C> until the Boot Menu appears.
In order for the VoIP to function, you must provide the device with the following information:
♦ Define where the device receives its IP settings from.
♦ IP settings – IP Address, Subnet Mask, and Default Gateway
♦ Gatekeeper Mode– Choose the Gatekeeper mode
♦ Gatekeeper IP –The Gatekeeper IP address is necessary if you chose the <Manual Discovery> item within the
Gatekeeper Mode
All of these settings are found in the first menu item in the Boot Menu named IP Configuration.
Use the <Tab> key to highlight the first menu item Configure IP and press <Enter>. The IP Configuration
screen will now be displayed:
DG-102SH VoIP Station Gateway

♦ Gatekeeper Mode Use the <Space> key to choose the Gatekeeper mode once the device is rebooted
(restarted). Choices include:
Auto Discovery – When Auto Discovery is chosen, the VoIP gateway will auto-search the Gatekeeper
from your LAN or WAN.
Manual Discovery – When Manual Discovery is chosen, the VoIP gateway will attempt to obtain the
Gatekeeper settings from the fields located just below.
No Gatekeeper – When No Gatekeeper is chosen, the VoIP gateway will not need Gatekeeper.
♦ Gatekeeper IP Enter an IP address for the Gatekeeper.
♦ BOOTP Use the <Space> key to choose the method that the VoIP gateway will use to obtain its IP
settings once it is rebooted (restarted). Choices include:
Manual – When Manual is chosen, the VoIP gateway will obtain its IP settings from the fields located
just below.
BOOTP – When BOOTP is chosen, the VoIP gateway will attempt to obtain its IP settings from a
BOOTP server located on your LAN.
DHCP – When DHCP is chosen, the VoIP gateway will attempt to obtain its IP settings from a DHCP

Your VoIP is now configured for use.
In order to use a web browser to configure the VoIP gateway, you must make sure it has a valid Ethernet
connection to a PC or LAN via its LAN or WAN ports.
The VoIP gateway comes with a default IP address of 10.1.10.4. You must make sure the PC is in the same IP
domain as the VoIP gateway. You can do this by changing the IP address of the PC as shown below.
Once this is done, run any browser on the PC and point it to the default IP address of the VoIP as shown below:
