Hatteras Networks Integrates with Micromuse's Netcool Suite to Deliver Complete Solution for Service Provider Network Management Systems.

RESEARCH TRIANGLE PARK, N.C. -- Hatteras Networks, the leader in high-bandwidth, symmetrical, last-mile Ethernet over copper access and service platforms, announced today its integration with Micromuse's Netcool(R) solutions to provide carriers with a robust service support infrastructure for large-scale standards-based Ethernet over copper service network deployments. As a member of the Micromuse Alliance Program(TM) Hatteras Networks' award-winning Ethernet over Copper platforms have been certified as Netcool Ready(TM) and are proven to interoperate with Micromuse's Netcool product family. This certification enables a carrier to perform cross-domain fault management across different platforms. Hatteras Networks' platforms can now be easily integrated into any Netcool-managed network, enabling real-time, end-to-end management. E[acute accent]The combined solution is already deployed and in use to manage a service-rich portfolio of Ethernet-based business services by Expedient. Expedient currently provides voice, video and data services in three North American markets and has plans to expand to 20 markets and 46 central offices by the end of 2005. E[acute accent]"Our relationship with Micromuse is enabling our mutual customers to quickly move through deployment to delivering business-grade Ethernet services over copper infrastructure," said Kevin Sheehan, president and CEO of Hatteras Networks. "Innovative service providers like Expedient are leveraging the advanced service activation, monitoring and management capabilities enabled by this partnership to rapidly roll out its Ethernet Anywhere service into new markets." E[acute accent]Through Micromuse's Alliance Program, Hatteras Networks and Micromuse will cooperatively pursue business, technical and marketing opportunities. The goals of the program are to provide flexibility, choice, and quick time-to-market for our customers through the development of integrated, viable solutions. Since its launch in 2000, the Micromuse Alliance Program has welcomed over 100 software and hardware vendors who offer best-of-breed solutions that are complementary to the Netcool suite of applications. E[acute accent]"As a Micromuse Alliance Program member, Hatteras Networks brings a unique ability to our mutual customers, enabling them to tap into the growing need for higher-performance services over the copper network," said John Sien, Vice President of OEMs and Alliances at Micromuse. "We look forward to working with Hatteras to create business opportunities and leverage both company's best-of-breed technologies to win new business." E[acute accent]With Hatteras Networks' Ethernet over bonded-copper broadband delivery platforms, carriers can deliver up to 45 Mbps of symmetrical Ethernet service over existing last-mile dry copper loops. This bandwidth flexibility gives carriers the ability to create a rich service portfolio that includes Ethernet private line, Transparent LAN services, Voice-over-IP, Internet Access from 1-45 Mbps, and virtual private networks (VPNs). These services are delivered seamlessly over the existing last-mile copper infrastructure, effectively bridging the existing T1 - T3 service gap and economic disparity.
