1 Introduction
1.1 Overview
The Conexant CX82320 ADLS USB Endpoint combines an “always-on”
high speed Asymmetric Digital Subscriber Line (ADSL) connection to the
telephone line, and a Universal Serial Bus (USB) connection to a computer
into a single cost-effective solution. The CX82320 ADSL USB Endpoint
solution hardware connects to the computer via USB interface. The ADSL
USB Endpoint supports T1.413-1998, G.dmt (G.992.1) and G.lite
(G.992.2) ADSL and is designed to operate in LAN and WAN modes. The
firmware running on the CX8320 is loaded from a computer through the
USB connection. Conexant supplies the software drivers for three kind of
operation systems- Mac OS X/9.0, Windows 98/2000/XP, and Red Hat
7.1/7.2 Linux.
In addition, the Conexant firmware includes the WindRiver Wind Web
Server to support the feature of embedded graphics configuration for
Conexant CX82320 products. Through the USB connection, end-user can
know the current configuration on the system.
1.2 Scope
This document provides the descriptions of the procedure to install and
uninstall the Windows USB driver for the CX82320 ADSL USB Endpoint
and the usages of the Web configuration pages.

2 Installation and Setup
2.1 Installation
2.1.1 Installing the ADSL USB Endpoint
The ADSL USB Reference Board can be connected to any available USB port connector
on the MACHINE. There are no option switches for the user to set. Once the board is
connected to the USB port and the driver software has been installed, connect the DSL
line input to the DSL RJ11 jack on the card. Some designs may have a second RJ11 for
connecting an ordinary telephone handset directly to the USB card.
2.1.2 Installing the Windows Driver
The ADSL USB Endpoint software can be installed when using the .inf files for
Windows plug-n-play.
The following examples are shown for a Windows 2000 operating system. Installations in
other Windows environments are similar.
2.1.2.1 INF Installation of the Windows Driver
1. With the computer running at the desktop, connect the ADSL-USB Reference Board
to the USB cable connected to the computer. The Windows operating system will
detect the new hardware.
2. When prompted with the Found New Hardware Wizard, select Next to continue.

SNR Margin: Amount of increased noise that can be tolerated while maintaining the
designed BER (bit error rate). The SNR Margin is set by Central Office DSLAM. If the
SNR Margin is increased, bit error rate performance will improve, but the data rate will
decrease. Conversely, if the SNR Margin is decreased, bit error rate performance will
decrease, but the data rate will increase.
Line Attenuation: Attenuation is the decrease in magnitude of the ADSL line signal
between the transmitter (Central Office DSLAM) and the receiver (Client ADSL
Modem), measured in dB. It is measured by calculating the difference in dB between the
signal power level received at the Client ADSL modem and the reference signal power
level transmitted from the Central Office DSLAM.
Errored Seconds: The error during Showtime, whenever, a given sec contains CRC
error, that second will be declared error second.
Loss of Signal: This field displays the count of event of ADSL signal loss.
Loss of Frame: This field displays the count of event of ADSL frame loss.
CRC Errors: This field displays the number of transmit data frames containing CRC
errors.
Data Rate: This field displays the ADSL data rate.
