Dataflex Chooses Virata Technology for New SHDSL and ADSL Integrated
Access Devices (IADs) to Address the Growing Voice-over-DSL Market

Virata* Corporation [Nasdaq: VRTA] today announced that Dataflex - a European supplier of innovative solutions to telecom operators - has selected a wide range of Virata processors and software for its newest SHDSL and ADSL IADs. The new Dataflex IAD9000 range for the small-to-medium-enterprise (SME) market incorporates Virata's Aluminum* 200 SHDSL chipset, Helium* communications processor and Magnesium* voice DSP to deliver superior reach and increased performance to service providers.

In addition, Dataflex is utilizing Virata's Beryllium* integrated communications processor and PHY and Magnesium* voice DSP for its low cost residential ADSL IAD products. "Dataflex has taken advantage of Virata's extensive product portfolio, which consists of all the major building blocks for designing ADSL and SHDSL broadband access devices," said Duncan Greatwood, vice president of marketing for Virata. "Our product portfolio was specifically designed to lower our customers' developments costs and speed time to market- and we are pleased to see Dataflex realise these competitive benefits."

"Given our long experience in the European voice and data products sector, Dataflex believes that there is a significant and long term opportunity for Voice-over-DSL within the broadband access market," said Robert Hopkins, business manager for xDSL Access Products at Dataflex. "The challenge in actually realising these opportunities is being able to deliver products that satisfy our customer bases' technical concerns.

By incorporating
Virata's innovative technology with our proven European ISDN and analog technologies, we can uniquely address concerns such as legacy equipment and standards support. This will then provide the operators with equipment that enables them to deliver value add business services, such as VoDSL, to their customers." VoDSL technology allows the
bandwidth of a high-speed Internet connection to be dynamically allocated into multiple "virtual" phone lines, making a single physical copper phone wire capable of carrying several simultaneous voice calls alongside the data. Thus, a small business could have many phone lines with enough remaining bandwidth for Internet access.

About Virata's Communication Processors and Chipsets

Virata's product portfolio includes a comprehensive selection of silicon, software and reference designs to better help equipment providers get their products to market quickly and cost-effectively. No other company integrates so much of the core software and silicon into one complete package - thereby significantly shaving development time and costs
associated with new product development.

Aluminum - In production now, Virata's Aluminum 200 DSL chipset is the industry's most complete SHDSL technology platform that delivers the highest data rates, longest DSL reach and lowest power consumption. With its unique technology features, the Aluminum 200 enables the design of symmetric DSL CPE products for the high-volume enterprise
and SOHO markets. Aluminum 200 is fully compliant with the ITU G.991.2 standard and has achieved complete interoperability with all leading SHDSL chipsets.

Beryllium - Representing the industry's first "ADSL home router on a chip," Beryllium integrates the functionality of Virata's best-selling Helium communications processor and an ADSL physical layer transceiver onto a single chip, delivering up to twice the long-loop
performance of alternative multi-chip ADSL router solutions.

Helium - Virata's flagship Helium family has been deployed in more than 7 million CPE installations worldwide. The Helium 210 delivers approximately 50 percent more throughput than the current Helium chips and is the industry's first communications processor with an "on-chip" 10/100 Ethernet MAC and PHY.

Magnesium - Magnesium bundles the powerful C54x DSP family from Texas Instruments with Virata's vCore, a complete line of voice processing algorithms and control-side device drivers under the Virata brand. This provides broadband equipment developers with access to the industry's first Integrated Software-on-Silicon(tm) (ISOS(tm)) voice
processing product.

Powerful Pre-integrated Software - All of Virata's communication processors feature Virata's leading ISOS platform, which delivers the most comprehensive and flexible software suite available on the market; as well as additional software components, such as self-provisioning and web management software. For example, a Helium 200/210 customer may take advantage of Virata's integrated EmWeb software, which enables end-users to remotely monitor, configure and manage devices or applications via the Internet using a standard web browser interface.

The self-provisioning support within the ISOS software suite supports the DSL Forum auto-provisioning standard, which should enable developers to take advantage of either approach without complicating the core design work or adding risk to their program. ISOS also delivers advanced software features such as PPPoE Client, Frame Relay, Ethernet Packet Filtering, Advanced ATM support and rt-VBR. Since all of these functions are pre-integrated as options in the ISOS software suite, developers are able to utilize whichever feature set they require without creating additional integration test requirements. This assists customers to significantly decrease development times and get products to market quickly and cost-effectively.
