Communications for the 21st Century
Modernization, expansion, the means to introduce multimedia services and the ability to roll out high-capacity broadband; these are the reasons BT is building a UK-wide, IP-based network, of which Ericsson's Telephony Softswitch is to be a key component.
Jun 15, 2005
BT Wholesale chief executive Paul Reynolds said in a statement last year that 21CN would give BT's customers more control, choice and flexibility than ever before. "The 21CN program will deliver our vision of a converged, multimedia world where our customers can access any communications service from any device, anywhere – and at broadband speed," he said. "21CN will drive a radical simplification of BT's operations, including significantly lower costs and the capability to launch new services to market faster than we can today."
Ericsson has been selected as the preferred supplier for the BT-defined "i-node" domain of the 21CN network. Situated at the core of the service-delivery function, the i-node includes softswitches, network intelligence features and bandwidth management capabilities. The Ericsson Telephony Softswitch is a key component of the i-node, introducing layered architecture to separate the network's service execution, service management, control and data transport functions.
As of April 2005, Ericsson has more than 35 Telephony Softswitch customers around the world. Leading operators, including MCI, TeliaSonera, Telenor, Korea Telecom and Telecom Egypt, have implemented or are on the way to implementing the solution in their networks. This allows operators to meet the challenges they face today while laying out a clear roadmap towards all-IP layered architecture.
BT's 21CN project is further stimulating the global evolution and deployment of layered architecture to deliver telephony, data and multimedia services over fixed networks. Not only does layered architecture enhance the consumer experience, it also brings operators the economic benefits of network consolidation, while supporting scalability, flexibility and telecom-grade quality of service.
