Congratulations on choosing the 3Com®OfficeConnect®Gateway,
your ADSL (Asymmetric Digital Subscriber Line) broadband
access solution. This guide describes how to set up the
OfficeConnect Gateway Data and Voice (3CR100AV97) base unit.

The OfficeConnect Gateway allows one or more networked
computers to connect to the Internet or a remote LAN (Local
Area Network). Once connected, local users (a local branch office)
can communicate with remote computers (the main office) as if
they were connected locally.

The four POTS (Plain Old Telephone System) voice ports enable
simultaneous delivery of up to four voice calls and continuous
high-speed Internet or remote LAN access over a single DSL
interface.

Setting up the OfficeConnect Gateway Data and Voice unit is a
three-step process:

1) Unpacking and positioning

2) Connecting the cables

3) Configuring the OfficeConnect Gateway

Introduction

Before You
Begin

This guide describes how to install and configure the
OfficeConnect Gateway Data and Voice base unit for broadband
internet access using the unit’s default settings. For most users,
you will not need to modify the default settings to support your
broadband access requirements.

To set up your OfficeConnect Gateway Data and Voice base unit
for shared access to the internet, you must have the following:

• An Internet Service Provider (ISP) account.

• ADSL Service already installed at your location, with an avail-
able ADSL wall jack, configured for data and voice services.

• A computer (PC) with Ethernet connectivity and TCP/IP soft-

ware. (Note: TCP/IP is automatically included with Windows
2000, ME, 98, 95, and NT.)

• A Web Browser, such as Microsoft Internet Explorer (4.0 or
later) or Netscape Navigator (4.0 or later), installed on your
computer.

Package
Contents

When positioning your OfficeConnect Gateway, make sure of the
following:

• Unit is out of direct sunlight and away from sources of heat.

and sources of electrical noise such as radios, transmitters, and
amplifiers.

• Air flow around the unit and through the vents in the side and

back of the case is not restricted. A minimum of 1 in. (2.54 cm)
clearance is recommended.

Using Rubber Feet and Stacking Clip

For desktop use, the four self-adhesive rubber feet
help to stabilize your OfficeConnect Gateway and pre­vent sliding. Attach the feet to the marked areas at
each corner of the underside of your OfficeConnect
Gateway.

In addition, the stacking clip provided may be used
for stacking any other OfficeConnect units, such as the
OfficeConnect Gateway Voice Expansion Unit or
OfficeConnect Ethernet hubs and switches, neatly and
securely together. You can stack up to a maximum of
four units. To stack your units, secure the clip as

color-coded to help you connect the cables properly.

The following illustration shows the connector cabling:

To connect the OfficeConnect Gateway’s cables:

Connect the DSL cable (black) to the ADSL wall jack and the
other end to the DSL port (black) of your OfficeConnect Gateway.

2. Connect the LAN cable.

Connect one end of the LAN cable (blue) to the Ethernet port of
your computer and the other end to the LAN port (blue) on the

3. Connect the Telephone Cable(s).

You can connect up to four POTS-based devices (telephones, fax
machines, or modems) to the Phone ports of the OfficeConnect
Gateway, using telephone cables (silver) such as the one pro­vided. Your Service Provider assigns phone numbers to each
port, and can tell you which phone ports on your unit corre­spond to the phone numbers. You can use the table on the left to
record the unique phone number for each phone port.

4. Connect the power adapter.

Connect the cable from the power adapter to the Power inlet on
the rear panel of the unit. Connect the power cord to the power
adapter. Connect the other end of the power cord into a surge­protected electrical outlet.
