  1. 21CN Voice Update April 2010 This pack has been designed to help communications providers to explain to their customers the rationale behind BT’s strategy for 21CN voice and what it means for them.

  2. Background BT announced its plans for 21CN in 2004. Since then, the company has delivered on its plans, which have also evolved in line with changing market requirements • The programme has evolved from a national planned migration from traditional to 21CN products to a customer-driven migration approach. • The delivery of next generation services has been prioritised. As a result, 21CN has delivered: • A voice replacement network delivered over IP; service quality on the new service is on a par with traditional voice services. • A new simpler and higher capacity core network better able to manage the growing volumes of video traffic. • ADSL2+ broadband, which offers customers higher speeds and greater functionality, to within reach of 14 million UK homes, with plans to increase this to 20 million homes by March 2011. • Ethernet from over 800 nodes across the UK, offering businesses higher speeds, greater flexibility and more cost effective data connectivity. 

  3. Programme review of 21CN Voice BT conducts periodic reviews of 21CN. 21CN voice has recently been reviewed. BT considered: • The advent of fibre-based broadband and the requirements for a voice capability to be delivered over FTTP. • The growing base of customers whose voice services are delivered over fully unbundled local loops. • The demand for a derived IP voice services to be delivered over broadband, rather than dedicated voice lines. • The potential for multiple migrations as this ‘mixed economy’ for voice evolves. • Openreach’s ongoing consultation on the technical specifications for a voice over fibre product.

  4. What has changed? • BT has decided to halt all plans to migrate a further 275,000 lines to the 21CN voice platform and considers that further mass migrations to the 21CN voice platform are unlikely. • We need to see what decisions are made with regard to delivering voice services over Fibre to the Premises. • We also need to recognise the proportion of the voice market that has moved, or have announced plans to move, to fully unbundled lines which no longer use BT’s voice services. • BT is committed to maintaining and investing in the 21CN voice platform. • Work continues across the industry on what the strategy needs to be for the overall delivery of future voice services.

  5. What happens next? • BT will continue to review what customers need for future voice services. • Customers that have already been migrated to the 21CN voice platform in South Wales (called Pathfinder) will continue to have their voice services delivered by that technology. • This decision on 21CN voice services has no impact on other 21CN services like higher speed broadband or data connectivity, the rollout of which continues.
