Business Wire, June 16, 2004

CLEARWATER, Fla. -- Digital Lightwave(R), Inc. (Nasdaq:DIGL), a leading provider of optical networking technology and test instruments, today announced that Cisco has selected the NIC(R) Plus in support of Next Generation Network (NGN) testing needs. Cisco has purchased Digital Lightwave products over a six-year span, most recently selecting the advanced testing capabilities of the NIC Plus to fulfill T-Carrier, SONET, SDH, OTN, ATM and Ethernet testing requirements.

Cisco equipment encompasses the complete capabilities of today's network from the enterprise to the core. The NIC Plus offers T-Carrier, SONET, SDH, OTN, ATM and Ethernet test capabilities in a single unit, making it a superior fit for today's leading network equipment manufacturers. Cisco is leveraging initial Digital Lightwave product investment by advancing to the latest and most efficient technologies offered in the NIC Plus platform.

"We're pleased to continue the longstanding relationship between our companies," said Michele Ozzimo, Western US Regional Director of Sales at Digital Lightwave. "We've crafted and matched our product direction to meet Cisco's present and future needs as well as those of other industry-leading companies. For example, our engineers customized our switch-to-protect time feature, specifically addressing the ability to view testing results data on a combined single screen, thereby reducing testing time and simplifying processes. By Cisco selecting the NIC Plus, in support of NGN testing, our advanced technologies are further validated in the technical community."

Industry-leading equipment manufacturers are embracing the development and implementation of NGN technologies, in turn creating a strong marketplace for Digital Lightwave's Network Information Computer(R), (NIC(R)) and Network Access Agent(R) (NAA(R)) products.
