Bus Doctor™ Protocol Analyzer for PCI Express™ Publicly Demonstrated on Three Continents over last Thirty Days with Intel®

New Orleans, LA (May 5, 2003) -- Data Transit Corporation, the leading supplier of modular bus protocol analyzers, announced it will demonstrate it's Bus Doctor Analyzer for PCI Express at the Microsoft® WinHEC tradeshow in New Orleans, which begins today. The Bus Doctor will also be used in Intel's booth at the exhibition to display their functional PCI Express prototype motherboard. Intel used the Bus Doctor for the same purpose within their booths at Intel Developer Forums in Tokyo, Japan and Berlin, Germany in April.

"We believe that our live demonstration of x4 and x8 PCI Express analysis illustrates our commitment to leadership in this market," said Dennis Evans, President, CEO and COO of Data Transit Corporation. "The Bus Doctor's configuration options and ability to examine different types of busses at the same time makes it uniquely positioned to meet the needs of companies developing systems using PCI Express technology."

"The industry is recognizing the advantages of PCI Express and is adopting this technology. Venues such as the Intel Developer Forums and WinHEC provide us with opportunities speak with these customers and show how our tools will help them get to market faster with better quality." said James Wright, Vice President of Sales and Marketing at Data Transit. "We are glad we can assist Intel in demonstrating PCI Express multi-serial lane operation, capabilities and performance."

PCI Express architecture is a serial I/O technology compatible with the current PCI software environment that offers low-cost, scalable performance for the next generation of computing and communications platforms. Suitable for both chip-to-chip and add-in card implementations, PCI Express technology defines a packetized protocol and a layered architecture that enables attachment to copper, optical, or emerging physical signaling media. These properties, combined with an initial bit rate of 2.5 Gigabits per second per lane per direction, make PCI Express architecture an ideal attach point for performance-intensive applications.

Data Transit will demonstrate its Bus Doctor analyzer and PacketMaker traffic generator product lines at WinHEC, booth #203. In addition to PCI Express, the company will feature its industry-leading Serial ATA and Serial Attached SCSI products. Data Transit will also demonstrate the Bus Doctor PCI Express protocol analyzer at the PCI-SIG™ Developers Conference June 2 and 3 in San Jose, Calif.
