Xspedius to Offer Services Over Lucent and Juniper Networks End-to-end IP Infrastructure

MURRAY HILL, N.J. and SUNNYVALE, CALIF., June 21, 2004 - Lucent Technologies (NYSE: LU) and Juniper Networks, Inc. (NASDAQ: JNPR) today announced that Xspedius Communications, an integrated communications provider (ICP) headquartered in O'Fallon, Mo., has selected a solution from Lucent's Accelerate™ Voice over Internet Protocol (VoIP) portfolio and Juniper Networks routing platforms. The three-year agreement paves the way for Xspedius to offer VoIP services to business customers throughout its network across the southern U.S., and has a value to Lucent of $35 million.

Xspedius will use the Lucent Accelerate™ solution to create an VoIP-ready network capable of providing its business customers with future VoIP applications such as voice virtual private networks, virtual contact centers, managed bandwidth services and unified communications, as well as traditional voice services. As a result of its relationship with Juniper Networks, Lucent will deliver, install and maintain Juniper routing platforms to support the enhanced IP services on Xspedius' network.

Lucent Worldwide Services is providing network integration, installation, maintenance and professional services.

"Xspedius has consistently sought out the best available technology for our customers' telecommunications needs," said Mark Senda, president and chief executive officer of Xspedius. "We are leveraging our financial strength and customer growth in local data and voice offerings across our 31 switch markets to make the technology transition to MPLS and VoIP solutions. Working with Lucent and Juniper gives us the network performance and smooth migration path to quickly expand our voice services over IP and MPLS-based product sets."

"Lucent continues to make serious inroads in the growing VoIP marketplace with contracts like these," said Gerry Cafaro, Lucent Technologies vice president. "Xspedius' success is evidence of its commitment to giving its clients the telecommunications tools they need to succeed, and as they continue to expand their reach and services, we look forward to supporting them with the solutions they need to meet their aggressive goals."

"We're proud to announce Xspedius as a joint customer with Lucent," said Kurt Melden, chief scientist, Juniper Networks. "The strategic relationship between our two companies enables customers to transform their networks to create IP/MPLS-based infrastructures with end-to-end high performance and assurance for supporting business-critical applications such as Voice over IP. This type of infrastructure is a key requirement for service providers evolving today's networks to Infranets, which combines the ubiquitous connectivity of the Internet with the assured performance and security of a private network."

Xspedius is deploying Lucent's 5E-XC™ switch from Accelerate™ portfolio and the Juniper Networks M-series routing platforms. The agreement also includes Lucent's PacketStar® (PSAX) 4500 Voice over Packet Media Gateways.
