Siemens Enters U.S. Carrier Ethernet Market with Release of SURPASS hiD Portfolio

Boca Raton, Fla., Mar 21, 2006, Siemens Communications Inc. today announced the availability of its SURPASS® hiD Carrier Ethernet products in the United States, already in deployment by more than 10 operators throughout Asia and Europe, including at Deutsche Telekom where Siemens’ carrier Ethernet switches support the operator’s television and video services. The Siemens® SURPASS hiD portfolio demonstrates carrier-class restoration time and reliability - key requirements in the U.S. market.

Designed to meet the challenges of triple-play residential services and Ethernet-based enterprise services, the SURPASS hiD Carrier Ethernet platform introduces a hybrid architecture of Enhanced Ethernet and Multi-protocol Label Switching (MPLS) technologies. The platform helps ensure operational efficiency and end-to-end Hierarchical Quality of Service (HQoS) per service and per subscriber, with sub-50 milliseconds resiliency.

The hybrid Ethernet/MPLS architecture helps to enable practically unlimited scalability and 99.999 (5-nines) percent service availability with synchronous optical network (SONET)-like restoration, including hard QoS for real-time applications. The SURPASS hiD Carrier Ethernet product suite is also compliant with Metro Ethernet Forum (MEF9) specifications and with Network Equipment-Building System Level 3 guidelines applied to telecommunications equipment in the United States.

Another key benefit that U.S. metro Ethernet providers require is end-to-end service provisioning. The SURPASS hiD portfolio offers complete provisioning capability, including service activation, resource management and service assurance.

“Siemens is bringing, to U.S. carriers, a proven portfolio of Ethernet edge-to-premises broadband network devices along with a hybrid Ethernet-MPLS aggregation approach to manage it all,” said Stan Hubbard, an analyst for Heavy Reading. “SURPASS hiD enables service providers to select, from a single vendor, either point solutions or total end-to-end solutions. This option helps to simplify and speed up a carrier’s deployment of metro Ethernet networks and also helps enable those networks to meet a carrier’s capacity and performance needs.”

The U.S. carrier switch and router market is experiencing rapid growth, expected to $637 million in 2008, according to Heavy Reading.

The Siemens LifeWorks Vision

The SURPASS hiD portfolio is another critical component of the Siemens LifeWorksTM vision to help people interact, work and be entertained - without technology boundaries - in an always-on world. The company’s award-winning LifeWorks vision provides the building blocks for the ongoing development of secure, reliable and high-quality converged communication solutions that drive greater efficiencies and improve user satisfaction.
