Getting to Know
the ADSLUSB Modem

Overview

Asymmetric Digital Subscriber Line (ADSL), the most popular residential
DSL technology, provides high-speed Internet access over regular, copper
phone lines by maximizing bandwidth use. In this way, ADSL Internet service
can coexist on the same line as your phone service, without disrupting calls.
ADSL is “asymmetric” because it downloads, or receives data, faster than
uploads it is transmitted. Asymmetric operation is ideal for home and small
office use where f iles and information are downloaded more frequently than
uploaded.

There are several standard types of ADSL modulation techniques, including
Discrete Multitone (DMT). Your ADSL USB Modem supports the following
DSL standards: ANSI T1.413 Issue 2, ITU G.992.1 (G.DMT) and ITU
G.992.2 (G.lite).

The USB Icon

The USB icon shown below marks a USB port on a PC or device.

To use this USB device, you must have Windows 98, 2000, or Millennium
installed on your PC. If you do not have Windows 98, 2000, or Millennium,
this device will not work.

Also, this device requires that a USB port is installed and enabled on your PC.
Some PCs have a disabled USB port. If your port doesn’t seem to be working,
there may be motherboard jumpers or a BIOS menu option that will enable the
USB port. See your PC’s user guide for details.

Some motherboards have USB interfaces, but no ports. You should be able to
install your own USB port and attach it to your PC’s motherboard using hard­ware purchased at most computer stores.

Troubleshooting

Common Problems and Solutions

This section offers solutions to common issues that may occur during the
installation and operation of your ADSL USB Modem.

1. Which protocols might I need to use with my ADSL USB Modem?

• Refer to the documentation or manual provided by your ISP for details.

The protocol required in your configuration depends on the equipment
used by your DSL service provider. There are several possibilities:

a. Point-to-Point Protocol Over ATM (PPPoA) (RFC 2364) - PPP

provides session setup, user authentication (login), and encapsulation
for upper-layer protocols such as IP (Internet Protocol). The use of
PPP makes the modem appear as a dial modem to the operating sys
tem. Dial-Up Networking is used to establish a connection. PPP is
supported by either the WAN (Wide Area Network) driver or the
ATM driver.

b. Bridged/Routed Ethernet/IP over ATM (RFC 1483) - This proto-

col makes the modem appear as a local area network (LAN) device
to the operating system.

c. Point-to-Point Protocol Over Ethernet (PPPoE) (RFC 2516) - PPP

provides session setup, user authentication (login), and encapsulation
for upper-layer protocols such as IP (Internet Protocol). PPP makes
the modem appear as a dial modem to the operating system. Dial-Up
Networking is used to establish a connection. The protocol must be
supported by WinPoet or Enternet 300 logon software on the RFC
1483 driver.

2. Installing the driver software resulted in unexpected errors or warnings.

Uninstall the ADSL USB Modem driver by doing the following:

a. Go to Start, Settings, Control Panel, and click on Add/Remove

Programs.

b. Highlight Linksys ADSL USB Modem.

c. Close the Control Panel window, and remove the program.

18. Click on the AAL Statistics tab to display information about your current

AAL statistics.
