Digital Lightwave, Inc., a leading provider of innovative optical networking products and technology, today announced that Livingston UK LTD, Europe's largest electronic equipment rental organization, has placed an order for the company's portable OC-192 Network Information Computer--the NIC 10G with the international STM-64 standard technology - for delivery to one of their major global customers. The order, valued at approximately $1.8 million, will commence shipment during the current quarter.

This order, placed through Digital Lightwave's international distributor, Conformance Standards Limited, LTD (CSL), marks the first international customer order placed through CSL, the leading communications equipment value-added reseller in the UK, Ireland and Benelux, which began representing Digital Lightwave in August 2000.

"With the Digital Lightwave NIC 10G, which includes the international SONET STM-64 standard, the ability to verify the installation of SDH optical networks allows our customers the same easy to use portable platform currently used in North America," said Peter van Poelgeest, sales manager for Livingston's Benelux region.

"We are pleased that Livingston has selected our high-speed solution for its international optical network installation and maintenance customer requirements," said George Matz, executive vice president for global sales at Digital Lightwave.
