19 June 2003 Beijing and Murray Hill, NJ Lightwave -- Lucent Technologies today announced that it has signed a contract with Hunan Unicom, a subsidiary of China Unicom, to build its provincial backbone transport network with Lucent's optical platforms.

Under terms of the contract, Lucent will supply Hunan Unicom a variety of SDH optical transport systems, including the new Metropolis ADM MultiService Mux, LambdaUnite MultiService Switch (MSS), and the WaveStar ADM 16/1. Lucent will also deploy network management systems, including the Navis Optical Element Management System (EMS) and the WaveStar ITM-SC to help Hunan Unicom smoothly integrate Lucent's hardware into its existing SDH network.

For the project, LambdaUnite MSSs will be deployed to form the core of the network. This will connect the 2.5-Gbit/sec rings throughout the province and the 10-Gbit/sec rings connected to data centers and long-haul switch centers.

"We are pleased to address Hunan Unicom's growing business needs by deploying Lucent's network transport equipment," asserts Jason Chi, chairman and president of Lucent China. "Our products will help Hunan Unicom significantly upgrade its backbone transport network in terms of system capacity, technical advantage, reliability, security as well as operational flexibility."

Developed by Bell Labs, LambdaUnite MSS bridges traffic between data-intense metro networks and high-speed optical core networks--connecting cities, campuses and corporate networks to larger, long-haul public networks. The product enables service providers like Hunan Unicom to upgrade their networks to 40 Gbits/sec and allows them to deliver new value-added services such as Gigabit Ethernet. The flexible single-shelf system was recently optimized for smaller metro applications, supporting in-service upgrades from 160 Gbits/ec to 320 Gbits/sec, as well as to 640 Gbits/sec, allowing the system to grow when network capacity increases. Mesh restoration capabilities were also added to help carriers migrate to new mesh-based networks, while at the same time, leveraging traditional protection architectures.

Metropolis ADM serves as an integrated Ethernet-over-SDH multiplexer, enabling service providers to migrate from existing TDM networks to data-aware packet networks. Adding data services to optical networks increases revenue potential for customers and helps them offer a wide variety of new Ethernet services. Metropolis ADM integrates into Hunan Unicom's existing infrastructure, avoiding the need for an overlay network built for new services.
