NEC's Carrier Ethernet Mobile Backhaul Solution demonstrates interoperability in Public Interoperability Event

*** For immediate use September 21, 2009

Tokyo, September 21, 2009 - NEC, a leading provider of next generation backhaul transport solutions is to exhibit its Carrier Ethernet ready switching and microwave radio products at the upcoming Carrier Ethernet World Congress (CEWC) 2009 in Berlin after successfully demonstrating interoperability at the EANTC test event held earlier this month.

The interoperability event, held from August 24th to September 4th 2009, provided NEC and other vendors an opportunity to demonstrate working migration solutions for mobile and fixed carriers evolving to Packet transport architectures with Carrier Ethernet and Ethernet Radio technologies. The focus of this year's event was Mobile Backhaul for LTE and WiMAX, Global Interconnect and Managed Ethernet Services.

During the event, NEC successfully demonstrated the interoperability of its highly intelligent and flexible mobile backhaul portfolio; PASOLINK NEO iP, PASOLINK NEO TE, PASOLINK NEO High Performance (HP) and Multi-Service Aggregation Switch CX2600.

Critical to Carrier Ethernet, Ethernet OAM (ITU-T Y.1731) enables the strict enforcement of customer SLAs and end to end health and performance management. NEC's Carrier Ethernet radio product (PASOLINK NEO iP) is among the first to implement Ethernet OAM in this product category. Tests conducted during the event proved NEC's implementation to provide highly accurate measurements bringing new levels of visibility and manageability to Ethernet backhaul networks.

In an industry first, NEC demonstrated packet based ring protection implemented on their Carrier Ethernet radio product, providing less than 50ms switchover time for increased reliability and availability of customer networks. The system uses Ethernet Ring Protection Switching (G.8032/Y.1344) for a robust and interoperable solution.

Further demonstrating NEC's commitment to provide the most robust Carrier Ethernet transport, NEC participated in the AMR (Adaptive Modulation Radio) demonstrations. This function allows an intelligent radio to react to poor environmental conditions (such as heavy rain) and protect important traffic by reducing the link capacity but carefully selecting the traffic which is allowed to cross the link until the environment improves when it will automatically recover to normal operation. Additionally, NEC is able to dynamically tune the traffic with QoS parameters in PASOLINK NEO HP. NEC is one of the few companies to provide the AMR with QoS functionality from QPSK to 256QAM.

PASOLINK NEO HP also demonstrated the Ethernet Jumbo Frame transmission for higher throughput communication.

The NEC portfolio's transport of TDM and ATM over MPLS was verified interoperable with products from other participating vendors.

Public demonstration will be showcased at the Carrier Ethernet World Congress' EANTC booth from September 22nd to 24th, 2009 in Berlin, Germany.
