E-series Enables Maxcom to Accommodate DSL Customer Growth and Offer New Triple-Play Services

SUNNYVALE, Calif., June 2, 2005 - Juniper Networks, Inc. (NASDAQ: JNPR) today announced that Maxcom Telecomunicaciones has deployed Juniper Networks E-series edge routing platforms to expand its broadband network and to introduce integrated voice, video and data services. Maxcom, one of the leading service providers for residential users and small- to medium-sized enterprises in Mexico City, Puebla and Queretaro, selected the E-series for its industry-leading performance, reliability and advanced service delivery capabilities.

The deployment of the Juniper Networks routing platform is part of a broader agreement Lucent Technologies announced last fall with MAXCOM. Lucent Worldwide Services (LWS) served as the multivendor systems integrator on the project and provided maintenance support.

The E-series is capable of providing multiple services - including broadband remote access server (BRAS), broadband video services, dedicated access, 802.11 wireless subscriber management, voice over IP, internet access, security services, network address translation - on a single platform. The modular architecture of the E-series enables service providers to deploy the right-sized router for their current needs and budget, while retaining the scalability to accommodate future growth.

"The E-series unique ability to provide multiple services on a single platform will enable Maxcom to rapidly and cost-effectively offer a triple play solution, which bundles switched voice, Internet and Pay-TV services," said Tim Lambie, vice- president, Americas International of Juniper Networks.
