NEC Launches NGN-Compatible TDM-RPR Hybrid Multiplexer

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 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 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.
