Deutsche Telekom Orders Siemens BRAS

CHELMSFORD, Mass. -- Deutsche Telekom has placed an order with Siemens Information and Communication Networks (ICN) to supply and power-on broadband network access technology from the Siemens subsidiary Unisphere Networks, Inc. Unisphere’s ERX Edge Routing Switch provides broadband access to the IP network and acts as a Broadband Remote Access Server (BRAS) for the product T-DSL. The BRAS is the Internet entry point via which users dial in to the network of their Service Provider, such as T-Online. The BRAS thus allows Fast Internet and IP VPN services to be provided cost-effectively for all T-DSL users. This order is already the biggest yet placed in Europe for BRAS technology. The Broadband Remote Access Servers are scheduled to go into operation by the end of March this year.

Unisphere’s ERX will be employed as a broadband Remote Access Server (RAS) in Deutsche Telekom’s IP network as the basis for its AAA services (Authentication, Authorization, Accounting) ensuring secure Internet access. ERX will also permit video streaming over the Internet because it routes the IP packets at delay-free “wire speed”. The high data transmission rate is thanks to ERX’s hardware-based ASIC concept which, for design reasons, operates much faster than software-based solutions.
