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.

DHCP: (Dynamic Host
Configuration Protocol)

:
Dynamic IP addressing is the
type of addressing scheme
most often used by Internet
Service Providers (ISPs), and
is also the type that is preva­lent in many existing
corporate networks.

The OfficeConnect Gateway,
which can act as a DHCP
server, is optimized for use
with dynamic, rather than
static, IP addressing.

For most users, it is most
likely that your computer or
computers are already set up
for dynamic IP addressing. By
default, the OfficeConnect
Gateway assigns IP addresses
dynamically to each attached
computer.

Each computer must be properly set up with TCP/IP and opti­mized for use with dynamic IP addressing.

Checking for Dynamic or Static IP Addressing

• From the Start Menu, select Settings, and then Control Panel.

Windows 95, 98 or NT:

Double-click the Network icon. From the Configuration tab of

the Network window, select TCP/IP for the Ethernet Network
Interface Card (NIC) that will be associated with your
OfficeConnect Gateway. For Windows NT: Click the Protocols tab
on the Network window, and then select TCP/IP. Click
Properties. Click the IP Address tab on the TCP/IP Properties
window.

Windows 2000:

Double-click the Network and Dial-up Connections icon, then

double-click the Local Area Connection icon. Click Properties
on the Local Area Connection Status window and then select
Internet Protocol (TCP/IP) from the list of components shown
on the General tab of the Local Area Connection Properties
window. Click the General tab on the Internet Protocol (TCP/IP)
Properties window.

• If Obtain an IP address automatically (Windows 95, 98, 2000) or
Obtain an IP address from a DHCP server (Windows NT) is

selected, your computer has a dynamic IP address.

• If Specify an IP address is selected, your computer has a static
IP address.

• Click Cancel to exit the window, and then click Cancel again on
the remaining windows until you get back to the Control Panel.

Where To Go from here…

If you are set up for dynamic IP addressing, proceed to the next
section, Configure the Gateway. If you are set up for static IP
addressing, record your settings. You will need them for your
final setup. Then set up dynamic addressing so you can continue
with the configuration of the OfficeConnect Gateway.

Once the unit is connected, the Power LED illuminates (green) on
the front panel of the OfficeConnect Gateway Data and Voice
unit. Wait for the Alert LED on the front panel to stop flashing
(amber) and transition to off, within 1-2 minutes.

When the Power LED is green and the Alert LED is off, it
indicates that the OfficeConnect Gateway Data and Voice unit has
successfully powered up, performed a Power On Self-Test (POST)
and is now operational.

If the WAN Interface Inactive message is displayed (Fig 4), your
first step is to create a password protected admin account and

configure the WAN interface.
Click Continue to proceed.

The system will display the

Username and Password Required

window (Fig 5) and prompts for
Username and Password. (Note:
The User Name and Password
entries are case-sensitive.)

The default value for the User Name is admin. There is no
default Password value. Enter admin in the User Name field and
leave the Password field blank (no entry). Click OK.

The system will display the Unprotected User window (Fig 6). You
need to assign a Password for your User Name (admin). This
window is displayed when the OfficeConnect Gateway Web

Configurator is accessed using
the system’s default password;
such as during the initial config­uration of the unit or after the
factory default settings have
been restored.

Click Apply and the WAN Interface Configuration screen will
appear. Continue on to the WAN Configuration section on page 6.

the settings you recorded earlier to set up your workstations and
the OfficeConnect Gateway for static IP addressing.

An example of an eight-user connection is shown below (Fig 8),
using a 3Com OfficeConnect Ethernet Hub 8.

1. Verify network configuration.

Check with your network administrator that the built-in DHCP
server will not cause conflicts on the network. In most instances,
however, the OfficeConnect Gateway will automatically detect
the presence of another DHCP server on the network and disable
its own built-in DHCP server.

2. Connect the LAN cable.

Connect one end of the LAN cable
(blue) to a port of the ethernet
hub and the other end to the LAN
port (blue) on the rear panel of the
OfficeConnect Gateway.

3. Uplink port configuration

The OfficeConnect Gateway will
automatically detect uplink ports
and configure itself accordingly.
No further action is required.
