Centillium Full Rate ADSL USB Number One, Says Independent Test Firm.Business Editors/High-Tech Writers FREMONT, Calif.--(BUSINESS WIRE)--Aug. 23, 2000 Full-Rate ADSL Modems Using Centillium Chipsets Score Throughput Rate Higher than 6 Mbps, Significantly Higher than Industry Average Centillium Communications, Inc. (Nasdaq:CTLM CTLM Imaging Computed tomography laser mammography A diagnostic technique using lasers to produce a 3-D cross-sectional image of the breast without x-rays. See Mammography. ), innovator of broadband communications technology, today announced the results of independent third party testing which demonstrated that its Flite Optimizer USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. chipsets, with a throughput rate higher than 6 Mbps, is nearly double the industry average -- 3 to 4 Mbps. The testing compared full-rate ADSL USB modems utilizing chipsets from top tier ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line chipset makers and concluded that, among those tested, modems using Centillium's Flite Optimizer USB chipsets are the fastest available today. These test results were based on Layer 4 throughput rates rather than the more-typically quoted Layer 1 payload rates. The difference is significant, since Layer 4 testing gives a more accurate indication of performance from the end user's perspective than Layer 1 testing. Layer 4 throughput measures the actual usable data transmitted from end to end. Layer 1 payload, on the other hand, is a measure of the capacity of the link and does not consider overhead and bottlenecks present in the higher protocol layers. "Layer 1 throughput rates are less relevant to the end user because they don't give a true indication of the actual speed for applications they use," said Pat Hurley, DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary analyst, TeleChoice. "One of the most common examples of this is the standard 56 kbps modem. Consumers typically net only 28-33 kbps performance from 56k modems. End users should feel confident when a modem says it can deliver at speeds of 6 Mbps that it can deliver a full 6 Mbps. Layer 4 testing provides that assurance and represents a significant advancement in the evaluation of modem performance." Independent Testing NSTL (National Software Testing Lab, Blue Bell, PA, www.nstl.com) An independent organization established in 1983 that evaluates computer hardware and software in the PC, mobile and gaming markets. It adheres to controlled testing methods to ensure objective results. performed comparison testing on Full Rate ADSL USB modems, utilizing Centillium's Optimizer chipset, as well as modems based on other Full Rate ADSL USB chipset providers. NSTL made use of a commercially available File Transfer Protocol A communications protocol used to transmit files without loss of data. A file transfer protocol can handle all types of files including binary files and ASCII text files. See Kermit, Zmodem and FTP. (FTP FTP in full file transfer protocol Internet protocol that allows a computer to send files to or receive files from another computer. Like many Internet resources, FTP works by means of a client-server architecture; the user runs client software to connect to ) client to generate traffic and measure the throughput. The test setup was based on commercially available equipment commonly used in ADSL deployments. The test report can be accessed via the web at http://www.centillium.com/inforequest.
