CLEARWATER, Fla. -- Digital Lightwave(R), Inc. (Nasdaq:DIGL), a leading provider of optical networking technology and test instruments, today announced the addition of Virtual Concatenation (VCAT) testing capability and Network Delay Simulation to its Network Information Computer(R) (NIC(R)) product line.

"The addition of VCAT and Network Delay Simulation continues to add to the value of the NIC product platform that customers worldwide have selected for use in their testing environments," said Doyle Mills, Director of Product Marketing at Digital Lightwave. "The flexible design of the NIC allows our engineers to seamlessly implement technologies that embrace today's testing needs as well as define those of the future."

VCAT is being implemented broadly around the world, most notably in Asia and Europe. VCAT enables a more efficient and flexible use of SONET/SDH bandwidth for packet-oriented traffic. The feature set includes control and measurement of all related alarms and errors as well as sub-rate channel delay.

Network Delay Simulation allows customers to create delays on sub-rate channels to simulate different physical path lengths without having to use actual fiber and racks of equipment. This feature meets the newest standards and allows users of the NIC to fully test their equipment at all levels of design, manufacturing and installation.

VCAT and Network Delay Simulation are available on all new NIC products or available as a software upgrade to existing NICs.
