TraceSpan Announces VDSL Xpert™ Multi-Layer Analyzer

Industry’s first and only non-intrusive performance-analysis solution

for VDSL2 interoperability testing

Las Vegas, NV - March 20, 2006 – TraceSpan™ Communications, a provider of broadband monitoring solutions, today announces the new VDSL Xpert™ multi-layer analyzer. Leveraging patent-pending technology, VDSL Xpert™ breaks new ground as the industry’s only non-intrusive performance-analysis solution for VDSL2 products. VDSL Xpert™ accelerates time to market and return on investment by cutting significant time from the development, deployment, debugging and interoperability verification of VDSL equipment. TraceSpan will demonstrate the VDSL Xpert™ for the first time at TelecomNext Booth #2037, Mandalay Bay Convention Center in Las Vegas, Nevada, March 20-22, 2006.

VDSL Xpert™ is an easy-to-use modular system designed for R&D and laboratory engineers engaged in the deployment of VDSL2 standard-compliant solutions. The innovative VDSL Xpert™ analyzer verifies the interoperability of VDSL2 products offered by different vendors, and compares the performance of any combination of CO (Central Office) and CPE (Customer Premises Equipment) modems. VDSL Xpert™ is a powerful solution for service providers (Telcos and CLECs), current and next-generation VDSL equipment manufacturers, and technology and chipset developers.

“We are proud to announce the launch of VDSL Xpert™ – our vendor-independent solution for VDSL interoperability testing,” said Dr. Hanan Herzberg, TraceSpan founder and CEO. “I am certain that the VDSL Xpert™ will follow the success and overwhelming acceptance of our ADSL analyzer, which received the 2005 Frost & Sullivan Product Innovation Award and is used currently worldwide by major carriers, modem and DSLAM makers and chip vendors. The VDSL Xpert is a PC-controlled hardware solution with a user-friendly GUI that presents multi-layer information in convenient displays. Using VDSL Xpert™, lab personnel can quickly and easily verify performance and compliance to standards of VDSL2 products, leading to rapid system deployment and quick return on investment.”

VDSL Xpert™ simultaneously presents downstream and upstream data and gives a complete and accurate analysis of VDSL product performance and interoperability without affecting data transfer between transceivers. With its unique multi-layer probing capability, VDSL Xpert™ focuses on the physical layer and provides comprehensive analysis of data without using on any VDSL2 chipset or being biased by any VDSL2 chip vendor.
