BT has introduced an ATM service that lets users add extra bandwidth without having to pay for new switches. Users can also increase their bandwidth incrementally.
Connection to the UK network, called Cellstream, is available at access speeds of 34Mbps and 155Mbps. Speeds of 2Mbps will be available later this year. Once connected, users can define their own virtual circuits and increase bandwidth at eight hours' notice.
The service also allows connectivity to the US by linking Cellstream to MCI?s Hyperstream ATM network. Access to parts of Europe is expected later this year.
Users can also define how the bandwidth is divided between voice and data. In the US, extra bandwidth can be added within three days.
Barry Hinton, BT?s ATM marketing manager, said: ?Customers can order additional connections, or adjust their bandwidth requirements, within hours. This flexibility removes the need to forecast bandwidth requirement in advance, as customers neither have to buy bandwidth they cannot use, nor constrain their wide area applications unnecessarily.?
Hinton said Cellstream is not aimed at replacing Virtual Private Networks (VPNs) in their core market of voice traffic. VPNs provide an expensive method of providing point-to-point services across the globe, and used predominantly for voice traffic. Instead, BT's service is targeted at large multinationals with diverse communications needs including multimedia, business TV and remote videoconferencing.
A VPN user wanting to increase from 5Mbps to 45Mbps over a year would have to pay #2.13 million including connection and rental charges. With Cellstream, it would cost #1.28 million in total because connection and port rental can be shared between many links. Once connected to Cellstream, users can continue adding bandwidth without having to order a new leased line.
