Copel Selects Juniper Networks for New IP/MPLS Network in Brazil

Advanced Communication Network Enables Copel to Deliver New Services to Corporate Clients and State Government Organizations

SUNNYVALE, Calif., April 5, 2004 - Juniper Networks, Inc. (Nasdaq: JNPR) today announced that Copel, one of the largest electrical power companies in Brazil, has selected the infranet-ready E- and M-series routing platforms for deployment in its new IP/MPLS/Gigabit Ethernet network. The new network will provide high-speed connections and new services in support of the Parana State government's digital inclusion initiatives. The network will be installed and supported by Damovo, a global service company providing state-of-the-art data, mobility and voice solutions.

The E- and M-series routing platforms provide the foundation for Copel's state-of-the-art network infrastructure that will deliver services such as voice and video over IP, videoconferencing and multimedia traffic to corporate clients, as well as to schools, city halls and municipal public service organizations across the state. The M20, M7i and ERX routing platforms uniquely combine best-in-class IP/MPLS capabilities with unmatched dependability, security, and IP/MPLS service richness to enable providers, such as Copel to move beyond simple Internet connectivity to an infranet model.

"Our goal is to build a high-performance, reliable and secure network infrastructure to effectively service our corporate clients and the state government, as well as fulfill our own IT requirements," said Renato de Oliveira Fontes, Copel's telecommunications superintendent. "Juniper Networks platforms are a critical component of our new advanced communication network, which will cost-effectively scale to meet the need of emerging services without performance compromise."

"Copel has deployed an early example of an infranet, which is an IP/MPLS-based network that is secure, reliable, and can deliver high quality to multiple applications," said Tim Lambie, vice president of sales, Americas International, Juniper Networks. "We applaud Copel's decision to build one of the most technically advanced network in the country that will serve the needs of both its customers and its own company today and into the future."

"We are pleased to work with Juniper Networks to provide Copel with industry-leading MPLS-optimized platforms," said Arnaldo Curvello, President Damovo do Brasil. "Their products were the superior choice, as they were designed and built for the scale and dependability that carriers, such as Copel, require."
