BT has launched its broadband internet service provider under the brand name BTopenworld. The asymmetric digital subscriber line service operates over a normal telephone line but offers high-speed, always-on internet access at a flat-rate price. It is aimed at small and medium-sized businesses, and includes access to a suite of Microsoft Office applications. BT says that at speeds of up to 2mbps, the BTopenworld business service will be up to 40 times faster than current modems. Previously, leased lines or an ISDN connection would have been needed to achieve similar speeds.
