NEC Launches NGN-Compatible TDM/RPR Hybrid Multiplexer for High-Speed, Highly Reliable 40 Gbps Networks; Base Model in Use by Rostelecom (Russia) and AIS (Thailand).

Tokyo, Japan, Dec 1, 2006 - (JCN Newswire) - NEC Corporation today announced the development and launch of SpectralWave UN5000, a hybrid multiplexer that provides simultaneous Time Division Multiplexing ("TDM") and Resilient Packet Ring ("RPR"*1) transport, in the Japanese market.

The new product combines TDM and packet transmissions to build a high-speed network (40 Gbps) capable of transmitting data at a maximum speed of 40 gigabits per second. It also features RPR and Generalized Multi-Protocol Label Switching ("GMPLS"*2) functions to build a highly reliable next-generation network ("NGN"). In addition, it offers various transmission services and meets inter-prefecture or inter-municipal transmission needs due to its many potential applications in underground areas as it can serve as a high-capacity SDH switch, providing multi-access line capacity, edge and backbone domains.

The SpectralWave UN5000 was released for overseas telecommunications carriers in August 2006. They have been shipped to Rostelecom in Russia and at AIS in Thailand, and are now in the final stage to put into commercial operation for their use. Based on this solid record in unit shipments, NEC is actively promoting sales of the equipment to domestic telecommunications carriers for building safe and reliable NGN networks.

This product will be shown in operation at Telecom 2006, being held in Hong Kong from December 4 - 8.

Flexible and highly reliable systems that handle system failure efficiently and assist building of a network that utilizes limited network resources are required in order to enable building of NGNs that are safe and reliable for different types of access equipment based on Internet Protocol ("IP"), and which also provide high-speed data transmission, video distribution and high value-added information. In addition, a unit with hybrid multiplexing that can flexibly set bandwidth to enable smooth and efficient migration from an existing network to a new network is essential. NEC's new product meets all of these needs.

Main Features of the SpectralWave UN5000

(1) Compatible with a 40 Gbps interface:

Has a built-in high-speed 40 Gbps interface to handle NGN needs for high-capacity data transmission.

(2) A hybrid TDM/L2 switch configuration makes migration from an existing network easy:

Offers mixed processing with both a TDM switch that features low delay and full bandwidth guarantee and a Layer 2 switch that makes it possible to share multiple interface bandwidths. In addition, it can handle network volume increases, making it economical and easy to migrate from a 2.4 Gbps ring to a 10 Gbps ring, or to a 10 Gbps x N multi-ring or 40 Gbps ring.

(3) Equipped with 10 Gbps RPR function:

Equipped with an IEEE802.17-compliant RPR function. 10-gigabit bandwidth can be shared among multiple bases, with traffic priority control available by user and/or service.

(4) Equipped with GMPLS for a highly reliable network:

GMPLS makes it possible to set up an independent distributed control optical network. This provides for a highly reliable network with a bypass function that activates at time of failure, and saves on equipment costs.

(5) 320 Gbps cross-connect function:

Equipped with a high-capacity 320 Gbps cross-connect function to manage high volumes of traffic.

(6) Saves space and energy:

NEC's high-precision mounting technologies have reduced the size of the unit by three-quarters, while reducing power consumption to nearly one half. (Compared to previous NEC models)

By combining the SpectralWave UN5000 with the SpectralWave DW4200 ROADM series (Reconfigurable Optical Add Drop Multiplexer), an integrated optical network can be built, for safe, reliable, and high-speed, high-capacity transmissions of NGN.

(*1) RPR (Resilient Packet Ring)

A transport technology specified by the IEEE 802.17 specification. It features fault resilience and highly effective utilization of available bandwidth.

(*2) GMPLS (Generalized Multi-Protocol Label Switching)

An automatic routing technology for signaling over a fiber network.

NEC at ITU Telecom World 2006 (NEC Stand at Hall 6, Stand N0.6002)

At ITU telecom World 2006 in Hong Kong from December 4th to 8th, 2006, NEC will be presenting NEC's Next Generation Network (NGN), which is realized through the utilization of the world's highest level of technological capabilities in both the IT and network field. With NEC's NGN, NEC will open the door to a "ubiquitous society" in which information is easily and safely accessible to anyone, anywhere, anytime, empowering enterprises, societies and individuals.Our exhibits consist of Seamless Community (Theme Stage), Triple Play, Service Delivery Network, Heterogeneous Access, Secure Networking, Broadband Access, Mobile Network Application, Enterprise FMC Solution and others.
