Introduction
This chapter discusses the following general DW7700 topics:
•Overview on page 1
•DW7700 components and supported features on page 2
•Professional installation or service requirement on page 3
•Preventive maintenance on page 3
•Operating considerations on page 3
Overview The DIRECWAY DW7700 shown in Figure 1 can provide
satellite Internet or Intranet connectivity to a single host or
multiple hosts on a local area network (LAN) when connected to
a properly aligned antenna assembly. A host may be a Point of
Sale (POS) terminal, credit verification device, or a computer
operating with a Windows, Unix, Mac, or Linux operating
system. The software required to operate the DW7700 resides in
the DW7700, which eliminates the need to install client software
on the host(s).

Chapter 1 • Introduction
21036332-0001 Revision C
The DW7700 contains unique components and supports features
that make it an ideal broadband communications solution for
enterprise-class customers. The components and features are
introduced in the following section, DW7700 components and
supported features, and are discussed in more detail in Chapter 2
– DW7700 component and feature descriptions.
DW7700 components
and supported features
The DW7700 contains the following components and supports
the listed features:
•Internal modem
Supports the DIRECWAY Virtual Private Network
Automatic Dial Backup (DVADB) feature. This feature
enables the DW7700 to send and receive data over a
terrestrial phone line should the satellite link between the
DW7700 and Network Operations Center (NOC) fail or
degrade below an acceptable threshold. A telephone cable is
connected to the TEL LINE port on the DW7700 and a phone
jack.
•Port forwarding
Allows servers on your LAN to receive specific transmission
control protocol (TCP) and user datagram protocol (UDP)
traffic from the Internet.
•Serial port
Enables you to connect a serial device, such as a POS
terminal, credit verification device, or Automated Teller
Machine (ATM) to the DW7700.
•Dual Ethernet ports
Allows you to connect two Ethernet devices to the DW7700.
Supported devices include PCs equipped with Network
Interface Cards (NICs), hubs, routers, switches, the
DIRECWAY Voice Appliance, and DIRECWAY Serial
Appliances. A DIRECWAY Serial Appliance can support up
to four serial devices.

Chapter 1 • Introduction
1036332-0001 Revision C 3
Professional installation
or service requirement
The Federal Communications Commission (FCC) requires
professional installation and service of the two-way antenna
assembly because it transmits radio frequency (RF) energy.
Preventive maintenance To maintain your DW7700:
•Keep the convection cooling vents free from blockage.
•Dust the unit as often as needed with a soft cloth.
•Do not use solvent or abrasive powder when cleaning.
No internal cleaning or service is required. The terminal does not
contain user serviceable parts. Opening or tampering with the
unit voids its warranty.
Operating
considerations
You must observe the warnings and cautions below to prevent
personal injury or damage to the DW7700.
CAUTION
•The two-way satellite dish must be installed in a location
or manner not readily accessible to children and so that
the dish bottom is at least 5 feet above ground level.
•Professional installation or service of the two-way
satellite dish is required by the Federal
Communications Commission because the radio
transmits radio frequency energy.
•This device emits radio frequency energy when in
transmit mode. To avoid injury, do not place head or
other body parts between the feed horn and satellite
dish when the system is operational.
•Unplug the indoor power connection before performing
maintenance or adding upgrades to any satellite dish
components.
•Do not allow anything to come in contact with the front
surface of the satellite dish.
WARNING
•Do not insert objects through the vents.
•Inserting objects through the vents may result in severe
personal injury or death due to electric shock.
•In addition, inserting objects through the vents may
damage the DW7700.

Chapter 1 • Introduction
41036332-0001 Revision C
CAUTION
•Keep the DW7700 in a well-ventilated space. Do not
place anything on top of it. Doing so may reduce heat
dissipation and cause operational problems or damage
the unit.
•Do not install near heat sources, such as radiators, heat
registers, stoves, or other apparatus (including
amplifiers) that produce heat.
•Never unplug the DC power cord from the DW7700 while
it is powered on. Doing so could damage the pins and
also cause a short in the system.
•When power needs to be removed from a DW7700 that
uses an AC/DC power supply, always unplug the AC
power cord from the wall outlet, surge protector, or
power strip.
•When power needs to be removed from a DW7700 that
uses a DC/DC power supply, always unplug the DC input
cable connector from the power supply.
•Do not place the DW7700 near equipment that produces
dust. Certain copiers or computer printers produce
carbon dust which can cause malfunctions.
•Position the DW7700 on a stable surface where it will
not be bumped or dropped.
•Prevent moisture from getting inside the DW7700.

Chapter 2
DW7700 component and feature
descriptions
This section describes the components and features introduced in
Chapter 1. The following topics are discussed:
•DVADB on page 5
•Port forwarding on page 10
•Serial devices on page 10
•Dual Ethernet ports on page 12
DVADB The DVADB feature enables the DW7700 to send and receive
data over a terrestrial phone line should the DW7700’s satellite
link fail or degrade below an acceptable threshold.
An RJ-11 telephone cable connects the DW7700 to a phone jack.
The DW7700 configuration in Figure 2 shows a sample DVADB
connection. The graphic is intended for illustrative purposes only
and may not reflect the DW7700 configuration at your site.
Figure 2: DW7700 DVADB connection

Chapter 2 • DW7700 component and feature descriptions
61036332-0001 Revision C
If the satellite link between the DW7700 and DIRECWAY NOC
fails or degrades below a certain threshold, the DW7700
automatically switches to DVADB mode. The DW7700’s
internal modem establishes a connection to a national network of
dial access numbers, which are known as a Points of Presence
(POP). Each POP acts as a Virtual Private Network (VPN) entry
point into your network or the Internet. Packets are sent from the
DW7700 through the POP to the DIRECWAY NOC, which
forwards the packets to the destination server. If necessary,
packets are routed from the destination server to the DIRECWAY
NOC and back to the DW7700
DVADB introduces no additional load on the DW7700 and does
not affect any existing DW7700 features, but it does cause the
DW7700 to send and receive data at a slower rate.
Optional protection module In some countries, the telephone lines are configured such that a
protection module is required between the DW7700 and the
outside PSTN telephone line. In those cases, Hughes provides
such a module (Part #9012740-0001). This module is a high
speed electronic circuit protector that provides over-voltage and
over-current protection in one component.
As of the date of this manual, the following countries require the
use of this optional protection module;
•Brazil
The protection module includes a short telephone cable that
connects to the telephone line port on the DW7700 and a
grounding cable with a ring terminal that connects to the
DW7700’s backplane.
Figure 3 illustrates DW7700 DVADB connections with the
optional protection module. Figure 4 illustrates details of the
protection module connections.

Troubleshooting DVADB You can follow these steps if you suspect the DW7700 is not
working properly in DVADB mode:
1. Verify at least one of the LEDs on the front of the DW7700 is
illuminated.
If none of the LEDs are illuminated:
a. Verify the DC power cord is securely connected to the
remote terminal.
b. Verify the power cord is securely connected to the power
source.
c. If the power cord is connected to a surge protector, verify
the surge protector is connected to a wall outlet and turned
on.
