June 28, 2006 Munich -- Siemens Communications Group has won a contract from TeliaSonera to build a universal DWDM transport backbone for the complete TeliaSonera group. Based on Siemens' Surpass Transparent Optical Networks portfolio, the new network will accommodate the Nordic carrier's growing volume of traffic by boosting existing transmission capacities.
With the Siemens Surpass equipment, service provisioning also will be speedier and more flexible, enabling the carrier to respond faster to various customer needs, such as new wavelength services, new client protocol formats, or additional protection channels, say Siemens representatives. The next-generation DWDM transport network will become the foundation for the delivery of all TeliaSonera services.
The first Siemens deployment in the TeliaSonera transport network was successfully completed in spring 2006.
TeliaSonera has a big presence in the Nordic and Baltic region, with extensive international operations throughout Europe and beyond. It is setting the pace in many markets for both residential and business customers, as well as for business-to-business services such as wavelength services.
"We selected the Siemens platform as it will meet our need for a reconfigurable photonic network that gives us a flexible transport architecture with the agility and scalability necessary to meet the dynamic requirements of our customers," explains Eva von Haartman, corporate director of TeliaSonera's multi-service backbone. "The Siemens solution's superior scalability and capabilities for transparent optical networking are impressive and helped us make this choice," she adds.
Siemens' Surpass Transparent Optical Networks portfolio includes the DWDM platforms Surpass hiT 7300, Surpass hiT 7500, and the management system TNMS. According to the company, the Surpass portfolio yields lower costs due to its full-channel optical add/drop multiplexer capabilities and photonic cross-connects, enabling remote configuration of a path without the need to access the network while staying all-optical through multiple add/drop nodes. Another highlight of the portfolio is the drastic simplification of installation, provisioning, and maintenance operations compared to current systems, claims the company. The Siemens system also features transponders that are tunable over the full wavelength band, resulting in quicker wavelength provisioning for customers, who no longer need to custom order "colors" of light. While the Siemens technology extends the distance between signal regeneration points to more than 3,000 km, it also comprises components for connections on a medium haul or regional scale, add company representatives.
