Level 3 Chooses Laurel ST200 Service Edge Router As One of Its Platforms for Data Service Expansion

June 21, 2004 - Chicago, IL - Laurel Networks, Inc. today announced that Level 3 Communications, Inc. has selected its ST200™ Service Edge Router as one of its platforms for an expansion of its (3)FlexSM data services in the US and Europe.

The Laurel ST200 was first deployed by Level 3 to deliver wide area Ethernet services in 2002. Since then, the ST200 has provided the service and interface flexibility, high reliability and capacity to evolve with the (3)Flex suite, supporting subsequent ATM and Frame Relay data service delivery to growing numbers of Level 3 customers in expanding markets. That proven performance has led to the selection of the ST200 to enable the expansion and enhancement of Level 3's IP VPN and lower-speed Ethernet, ATM and Frame Relay services.

"(3)Flex is a leading example of the benefits of an advanced, multi-service network," said Don Pyle, CEO, Laurel Networks. "Its continually evolving suite of converged voice, video and data services combines new levels of efficiency and flexibility with the reliability and security required by the most demanding users. We are extremely pleased that Level 3 has once again selected the ST200 to power these advanced services."

The (3)Flex family of data services, which includes (3)Flex Ethernet, (3)Flex ATM, (3)Flex Frame Relay, and (3)Flex Network IP VPN, reduces costs and simplifies the task of transporting voice, video and data across wide area networks (WANs). The four services currently provide secure video, voice and data transmission to and from more than 90 markets in the U.S. and Europe.

The (3)Flex Network IP VPN service allows organizations to securely and cost-effectively connect employees and others in headquarter, satellite and remote offices. The service also provides secure access to company intranets and extranets. Level 3's IP VPN service enables the consolidation of traffic that currently rides on different networks, allowing small, medium and large customers to more cost-effectively manage their voice, video and data traffic.
