BT will begin offering a Wholesale Broadband Connect (WBC) service to ISPs over its 21st Century Network (21CN). 
The service uses ADSL2+ for a maximum downstream capacity of 24 Mbps (distance from the exchange, internal wiring, interference from electrical appliances and other factors affect performance.)
Wholesale Broadband Connec will initially be available from exchanges serving around one million homes and businesses. The service will progressively roll out across the country, rising to a potential footprint of 10 million homes and businesses by the spring of 2009.http://www.btplc.com
