Introduction This guide describes the setup and installation of a USB CPE modem with the Centillium Communications Optimizer USB chipset CT-L22DU15, digital chip and CT-L21ATOI, analog chip. The guide will cover the installation of:
Windows 98 software drivers for the RFC 1483 network protocol Windows 98 software drivers for the PPP over ATM protocol e A User interface for monitoring the DSL link (for RFC 1483 protocol only) 2. System Requirements The Optimizer USB modem requires the following host system:
e PC, Pentium-class, 166 MHz or better recommended Windows 98 or Windows 98, 2 edition 16-Mbytes RAM, 32 Mbytes recommended e Hard disk space of at least 20 Mbytes One available USB port The user may also need access to the Windows 98 or Windows 98, 2" edition installation CD-ROM. 3. Software Shipped by Centillium The files needed for the installation of the software are available in the following formats:
Two or more compressed files (zip-format) 3.5 floppy disks CD-ROM If you are using the floppy disks or compressed files, unzip all zipped files into a directory on your computer. The zip files already contain the correct directory structure for the installation. If you are using the CD-ROM, there is no need for copying the files onto the host PC. The files are organized in three directories:
RFC1483 with the driver for the RFC 1483 protocol PPPoA with the driver for the PPP over ATM protocol UI with the user interface In addition, there are documentation files, like this Installation Guide. S Optimizer USB Installation Guide CENTILLIUM COMMUNICATIONS 4. Software Installation The users ISP (internet service provider) will provide information on which of the two protocols, RFC 1483 or PPP over ATM, needs to be installed. The user needs to install only one of them. 4.1. RFC 1483 Device Drivers Installation 4.1.1.

It indicates the upstream and downstream data rates, receive and transmit cell and error count, and an indication of the status of the ADSL link. The user interface can only be used with the RFC 1483 protocol. 4.5.1. Installing the User Interface The installation of the user interface is semi-automatic consisting of the popular Installshield application and an additional installation program. 1, Go to the ui directory, unzipped from the zipped file or copied from the floppy disks or CDROM. 2. Double click on setup.exe, which will invoke an Installshield. 3. Follow the steps of the Installshield:
Read the license agreement and proceed if you agree with its terms and conditions. e Inthe subsequent dialogue box, fill in your name, name of your company, and at this time an arbitrary serial number. Note that you cannot go to the next screen without filling in a serial number. The last step will generate a program group with icons for the user interface, a Readme file and a helpfile, Note that on some screens the program group may hide the final screen of the Installshield. 4. After successfully completing Installshield, double click on the MSDOS program Install, which is listed in the program group that opened before the final step of the Installshield. This will perform the necessary TCP/IP settings for the user interface. Please note that if you run the program install.exe instead, located in the ui directory, it will terminate with an error and the installation will not be completed. e Ifa dialogue box pops up like the one shown below, specify the path to the directory where you copied or unzipped the ui directory (for example, C:\ui), then click OK. 21 oS Optimizer USB Installation Guide CeENTILLIUM COMMUNICATIONS 5. Ifa dialogue box appears asking for the network protocol, click the Have disk button and specify the path to the ui directory (for example, D:\ui for the CD-ROM). 6. Once the installation is finished, reboot the computer. Note that there is no automatic reboot and that the user interface will not work properly without rebooting at the end of the installation. 7. When the computer is rebooted, you can open the user interface by typing ui into the Start - Run... Windows 98 menu option, or access it from the Start programs menu. The sample screen of the user interface shows that the modem is in Show time state and connects at a line rate of 576/1632 kbps up/downstream. Please note that the dials and the Ixkbps and Rxkbps windows indicate the data rate that is being used by the application running, not the maximum available datarate. In this example, the data rate being used by web browsing is 59 kbps upstream and 1031 kbps downstream. When web browsing, the dials and the Zxkbps and Rxkbps data rates will change frequently, as most browsers transmit and receive relatively short, but many packets of data. A click on More will show the following screen:
