25 June 2003 Beijing Lightwave -- Shaanxi Telecom, a subsidiary of China Telecom, has selected an infrastructure solution from Nortel Networks for expansion of its Internet Protocol (IP)-based MAN in Shaanxi Province. The solution--including what is expected to be China's first deployment of coarse WDM (CWDM) technology--will help position Shaanxi Telecom to address growing requirements for broadband services in five of the province's major cities: Xianyang, Ankang, Yulin, Yan'an, and Tongchuan. Shaanxi Telecom plans to put its expanded network into commercial service in August 2003.
CWDM technology makes available untapped capacity that exists in the singlemode optical fiber networks typically available in metro environments today. This can give service providers additional capacity to help drive new service revenues without requiring additional fiber, explain Nortel representatives. CWDM also affords more granular control of fiber bandwidth, making it possible for service providers to lease individual wavelengths and to offer premium services delivery.
"Shaanxi Telecom's selection of Nortel Networks further demonstrates the strength and breadth of our technology and experience in delivering high-performance networks to service providers across China," contends Robert Mao, president and chief executive officer, Nortel Networks China. "This is, in fact, our fundamental strength--building reliable, 'future-proof' networks for cost-effective provisioning of new, value-added services."
Shaanxi Telecom will deploy Nortel Networks Passport 8600 Ethernet Routing Switches and Nortel Networks Shasta 5000 Broadband Service Node (BSN) to provide such value-added services as broadband Internet access, broadband content, IP Virtual Private Networks (VPNs), and traffic management for business and residential users.
Passport 8600, a key component of Nortel Networks Optical Ethernet solution, is designed to deliver Gigabit-Ethernet performance and quality of service (QoS) for campus and building backbones, routing, or MAN connectivity.
Shasta 5000 BSN positions service providers to transition from the simple connectivity model enabled by first generation subscriber management systems to a network-based, value-added broadband services model. Shasta 5000 BSN supports wholesale dial; digital subscriber line (DSL); fixed and mobile wireless; metro optical and Ethernet extension; ATM; frame relay; and leased-line subscribers.
