It has been organized in a way that should make it easy to follow by users worldwide. In order to ensure optimal comprehension, the following list provides brief descriptions of the formatting styles used in this manual. • Commands: Commands are always shown as shadow words with the word “click” preceding them. For example, click Next, click OK, or click Cancel. • Names of Windows (Dialog Boxes): The names of the windows (also referred to as dialog boxes) that appear on the PC screen are referred to in Bold. For example, the Remote Access Setup window, or the Setup Wizard. • Names of Options in Windows: The names of options to choose from inside the windows that appear on the PC screen are referred to in shadow. For example, choose the Don’t detect my modem option, or choose the Accept any authentication option from the window. • Notes: In some cases, preparatory or cautionary information is needed before proceeding onto the next step in an installation process. This kind of information is provided in the form of notes, which appear in a frame: Note: Required if not using default value. 2 This manual contains information regarding the installation, operation, and configuration of the USB ADSL Modem. Additionally, it outlines the use of the Control Panel Application. The following chapters are included in this manual: • Overview: It offers a brief description of ADSL, protocol and device driver selection, and the features of the USB ADSL Modem. • USB ADSL Modem Hardware Installation It describes the steps for connecting the USB ADSL Modem. • Software Installation It describes the steps for installing the USB ADSL Modem drivers under various operating systems. • Customizing Communication Settings It provides detailed steps for altering the ATM Virtual Path ID (VPI), ATM Virtual Circuit ID (VCI), Encapsulation type and/or Modulation type values previously defined. • Updating the USB ADSL Modem Software It details the procedure for updating to a new version of the modem software. • The DSL Modem Status It describes how to configure and check the performance of the USB ADSL Modem and the ADSL connection. • Software Uninstall It provides detailed steps for removing the USB ADSL modem software from the PC. 3 About ADSL Asymmetric Digital Subscriber Line (ADSL) technology provides high-speed data access across regular phone lines (copper wires) by making use of previously unused frequency bandwidth above the voice band. By placing the ADSL signal above the frequency of the voice signal, ADSL service is able to coexist on the same line with your telephone service. ADSL is asymmetric in the sense that it provides a higher data rate in the downstream (receive) direction than in the upstream (transmit) direction. Asymmetric operation is ideal for typical home and small office use where files and information are downloaded more frequently than uploaded. The USB ADSL Modem is capable of supporting the following DSL standards: ANSI T1.413 Issue 2, ITU G.992.1 (G.DMT), ITU G.992.2 (G.lite), and ITU G.992 Annexes A, B, and C as applicable. Protocol and Device Driver Selection The USB ADSL Modem can be easily connected to a USB port on the PC via a standard USB cable. The USB ADSL Modem is fully software upgradeable so that new features and updates may be added by simply loading a new version of the device driver onto your PC. ADSL modems employ ATM (Asynchronous Transfer Mode) framing. ATM is a protocol that divides packets into small fixed sized cells for rapid transmission over high-speed networks. The ATM protocol allows various types of traffic (e.g. data, voice, and video) to be securely and efficiently carried over the same network. ATM is being widely deployed by telecommunications carriers in their backbone networks. Two type of ATM connections are possible, PVC (Permanent Virtual Circuit) and SVC (Switched Virtual Circuit). 4 Several different protocols are used on top of ATM. The protocol required in your configuration depends on the equipment deployed by your DSL service provider. There are several possibilities: 1. Point to Point Protocol (PPP) Over ATM (RFC 23...
