BT last week outlined a series of network developments including BeTaNet, an advanced internetworking protocol and multimedia network which is now in operation.
The company is to spend more than £5bn in the next five years for extensions and enhancements of the service to support data and multimedia services.
BeTaNet will offer customers almost unlimited bandwidth over a single link for simultaneous voice, data, video and internet services, and new intranet-based services for commercial and industrial customers.
The total UK data communications market is expected to grow by more than 150% over the next five years, creating a UK market valued at up to £10bn.
BT also revealed that a new pan-European communications network is undergoing trials before going live in March. This has involved installing 5,000km of fibre to connect 27,000km of fibre within the networks of European telecoms partners.
The network will be extended by a further 5,000km of fibre by summer.
