ADVISORY...for Wednesday (April 18)

ALAMEDA, Calif.--(BUSINESS WIRE)--April 18, 2001

Members of the media community are invited to hear Peter Buckner, Chief Technology Officer of TCSI (Nasdaq:TCSI) and 20 year veteran of the telecommunications software industry, present a corporate briefing at the Next Generation Network (NGN) Ventures Conference in Burlingame, California, on April 18, 2001 at 6:20 p.m.

In a presentation titled "Designing an Element Management System (EMS)," Buckner will discuss common network management problems, focusing on advanced, new software solutions that can accelerate the progress and profitability of emerging telecommunications equipment manufacturers (TEM's). The lecture will benefit TEM's who want to learn how to deliver adaptable and scalable EMS solutions that emphasize the key aspects of the hardware, as well as provide sufficient flexibility to weather the frequent changes brought about by rapid hardware development, and the frequent mergers and acquisitions of the telecommunications industry.

"Today's emerging TEM's must provide more than a basic management system with their hardware offering. Mediocre management systems will impede the progress of their product going to trial, hide the product's key features, or cause serious operational problems in the post-deployment phase," explained Mr. Buckner. "High-performance management systems must be designed for the long-term, with forward-looking consideration to fulfilling the needs of expanding service providers and emerging technologies."
