Topnet AG is incorporating an advanced IP+ATM backbone into their existing network using Cisco BPX. 8600 series wide-area switches.

Their IP+ATM network will enable Topnet AG to deploy Internet access services as well as new advanced IP services including Virtual Private Networks (VPNs), Voice over IP (VoIP) and video over IP to their customers in Germany.

The Cisco BPX 8600 series switch provides the industry's highest port densities and unmatched ATM and IP scalability, enabling Topnet AG to easily manage the accelerated growth of its networks. The BPX 8600 series also brings the application richness of Cisco IOS. software to a multiservice ATM environment. This capability allows Topnet AG to maximize its return on investment by offering multiple revenue streams on a single platform. The carrier-class reliability of the Cisco BPX enables Topnet AG's services to be available around-the-clock.

"With Cisco's products, we were able to quickly move from purchasing equipment to providing diverse services to our customers which made Cisco the obvious vendor of choice for us," said Rolf Krause, director of Topnet AG. "We believe customers want complete solutions from one ISP. With our relationship and IP+ATM products from Cisco, we are able to provide all the leading-edge and innovative services that our business customers demand."
