WESTFORD, Mass. -- Unisphere Networks, Inc. today announced the introduction and immediate availability of the MRX, the industry's first Multi-Service Edge Router. The MRX is designed to meet the multi-service requirements at the edge of service provider networks by integrating carrier-class IP routing, native ATM switching, Multiprotocol Label Switching (MPLS) and IP services in a single platform, with capacity scaling from 40 Gbps to 320 Gbps. The MRX expands Unisphere Networks' edge routing product portfolio and complements its award-winning ERX Edge Routers currently deployed in more than 150 service provider networks worldwide. With a wide range of optical interfaces ranging from OC-3 to OC-48 and Gigabit Ethernet powered by a field proven operating system, the MRX provides the ability to mix and match port speeds, and for the first time, mix and match native ATM, POS and MPLS protocols on a single line module. This unique any service, any port, any channel capability makes the MRX Multi-Service Edge Router a more cost-effective choice for incumbent service provider networks that require both ATM and IP functionality. The capacity and service delivery of the MRX can be used in a number of service provider edge applications, such as circuit aggregation and Metropolitan Area Networks, where Gigabit Ethernet is the transport option of choice. "In keeping with Unisphere Networks' global perspective, we designed the MRX to meet the evolving edge requirements of incumbent service providers around the world," said James Dolce, president and CEO, Unisphere Networks. "The MRX combines IP routing and ATM switching capabilities in a single, integrated product, which enables service providers to expand their service portfolios across both ATM-based and IP-based networks with a platform that provides a migration path to a common IP-based network."Unisphere Networks Inc.
