Following the installation in 2007 of a carrier-grade Class 4 TELES NGN solution – one of the largest projects of its kind in Europe – freenet's migration from TDM to NGN has now been successfully completed. The solution enables freenet to migrate from TDM to a full next generation network (NGN) backbone from which its carrier customers will now also benefit.
Stephan Esch, freenet's CTO, has been keeping a close eye on progress: "The TELES solution built a bridge to our existing VoIP services and now we have been able to integrate our DSL-based VoIP-subscribers and all legacy services into a single, standard-based NGN architecture." Apart from an increase in QoS and functionality, Andreas Jürgensen, managing director of the business unit fixed line technology of freenet Cityline GmbH, is also impressed with other benefits gained: "The replacement of our existing system with NGN backbone means a reduced carbon footprint thanks to lower power requirements. Also, less space is required to house the hardware, there has been a substantial reduction in costs, and maintenance is now centralized."
Frank Paetsch, TELES CTO, has followed each step of the deployment through to full migration and believes that the project represents a significant achievement for TELES: "We are very proud to have been given the opportunity by freenet to demonstrate our ability to take on a large-scale and complex project such as this, and we are also very proud of the work we have done to see this deployment through to its successful conclusion."
TELES Class 4 Softswitch cluster technology provides freenet and its customers with five-nines availability, geographically distributed redundancy, support for up to 10 million busy hour call attempts, an advanced and programmable call routing engine, and any-to-any protocol interworking. In addition to its cost-effectiveness and scalability, the Softswitch can be remotely managed, configured, and deployed.
