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 provides two
10/100MbpsFast Ethernet ports. OneEthernetportis for a DSL/CableModem
or other WAN devices and the other may function as a connection to create a
home or small office LAN network. Enabling NAT on the DG-104SH will allow
multiple clients to connect to the Internet. It can be configured/monitored via
theConsole, Webbrowser,orTelnetandSNMPmanagement isalsosupported.
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
relying on the Internet service providers to deliver toll-quality voice
communications over the IP networks.

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.
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).
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.


Test: This LED will flash quickly when the DG-104SH 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 Gatekeeper. It will remain dark when the
system is ready but can not receive an acknowledgement from the
Gatekeeper.

10
Line: Lights when PSTN line is in use.
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.
LAN: ThisLEDdisplaysthe 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 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 off and on.

Configuration
Configuring the VoIP Gateway
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.
Using a web browser on a computer connected to the device via the
WANor LANEthernetconnections. Inthediscussion below, thecomputer
running the browser is referred to as the management station.

There are two ways to configure the VoIP gateway:
Configuring the VoIP Gateway Using a Console
Setting up a Console
First-time configuration can be carried out through a “console,” that is, either
(a)a VT100-typeserial dataterminal, or(b) acomputer runningcommunications
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-
232cable anda null-modemadapter.Oneendofthecable(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:
9600baud
VT-100/ANSI compatible
No parity checking (sometimes referred to as “no parity”)

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 pro-
gram (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 uses 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.

Configuration
Configuring the VoIPGateway
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
isrecommendedthatyouusetheTabkeyandBackspacekeyfor moving
around the console.
Items in UPPERCASE are commands. Moving the selection to a com-
mand and pressing Enter will execute that command, e.g. APPLY, etc.
Note: The command APPLY only applies for the current session. Use Save
Changes from the Main Menu for permanent changes.
