ATLANTA--(BUSINESS WIRE)--June 6, 2000

Unprecedented level of scalability and performance

with new optical packet interfaces

SUPERCOMM (Booth 6815) - Lucent Technologies (NYSE: LU) today announced new multiservice capabilities and performance enhancements for its industry-leading GX 550(tm) asynchronous transfer mode (ATM) switch. The enhancements include optical packet interfaces to deliver Internet protocol (IP) services supporting standards-based multi-protocol label switching (MPLS), frame relay and enhanced quality of service (QoS). Additional enhancements include improved circuit density and new switch processor technology enabling service providers to better meet the explosive demand for digital subscriber line (DSL) and IP MPLS services.

"As a leading provider of Intelligent IP networking to 75 of the top 100 banks worldwide and 45 of the top 50 brokerages, QoS levels are critically important to our business," said Rob McCormick, CEO of SAVVIS Communications. "The ability to manage QoS in the context of the emerging MPLS standard is a feature which is important to the exacting requirements necessary to carry mission-critical financial applications. SAVVIS operates the world's largest financial extranet, and Lucent's next-generation multiservice WAN switching technologies will help us deliver on our high-performance commitment."

New optical packet interfaces for the GX 550 include:

- OC-3/STM-1 Packet & Frame over SONET/SDH

- OC-12/STM-4 Packet & Frame over SONET/SDH

- Gigabit Ethernet/IP/MPLS

- IP Server

The new processor technology and improved circuit density enables the GX 550 to deliver up to five times the performance providing greater network scalability --- allowing the service provider's networks to support more users. The GX 550 incorporates Intel's 500 Mhz, Pentium(r) III processor. "Lucent's Multiservice product family offers service providers an intelligent approach to building next-generation high-speed data networking solutions," said Tom Franz, vice president and general manager of the Network Processor Group, Intel. "Intel's award-winning Pentium III processors provide leading-edge performance and scalability to support the requirements of carrier class services."

Lucent is currently the market leader with 64 percent (as reported by Ryan Hankin Kent) of the core ATM market based on its GX 550 product. "The new optical packet interfaces and performance improvements add even greater depth to our industry-leading Multiservice switching portfolio further expanding Lucent's comprehensive data product offering," said Sarbpreet Singh, vice president product management, Core Switching, Lucent Technologies InterNetworking Systems. "These new features will help service providers with the build-out of next generation network services such as DSL, VPNs, wireless and Voice over IP services."

Lucent's Market Leading Multiservice IP/MPLS Switching Solutions

Lucent's Multiservice WAN solutions include the GX 550, CBX 500(tm) and B-STDX 9000(tm) Multiservice WAN switches, IP Navigator(tm) MPLS, and NavisCore(tm) and NavisXtend(tm) network management control software, which provides end-to-end network management. IP Navigator MPLS allows service providers to manage and provision IP services on the ATM backbone, which adds IP Layer 3 routing to Lucent's WAN switches and "Absolute" QoS. This multiservice system allows service providers to deliver and manage all services - ATM, Frame Relay and IP - from a single ATM core network and provides a manageable, scalable, carrier-class network infrastructure specifically designed for service providers.

Lucent is the No.1 market leader worldwide in Multiservice WAN Switching as recently reported by Cahners In-Stat Group, Dell'Oro Group and Synergy Research Group.

Lucent is an active participant in the Internet Engineering Task Force (IETF) MPLS working group as well as a participant in several working groups. In addition, Lucent is one of the founding members of the MPLS Forum, and the Vice Chairman of the Board and Chair of the Technical Committee positions are held by Lucent representatives.

The new optical packet interfaces will be available in the fourth quarter of 2000. Interface pricing for OC-3/STM-1 is $8,500 per port; for OC-12/STM-4 is $14,000 per port and for Gigabit Ethernet/IP is $10,000 per port.
