Companies that do not want to pay expensive leased-line set up costs can now use a cheaper, specially configured DSL broadband service from Viatel that doubles the data send speed of conventional broadband.

Basic ADSL (asymmetric digital subscriber line) is not suitable for many companies as the upload speed is only half of the download speed. Organisations that need to send large files, such as drawings and artwork, have to rely on expensive leased lines, which allow data to be sent at the same speed in each direction.
BT has launched SDSL (symmetrical digital subscriber line) as an alternative in some urban areas, but it is not planning a widespread roll-out of the technology to smaller towns and is not covering rural areas.
To get round the cost and availability problems associated with symmetrical services, Viatel has launched its Bonded Broadband service, which joins together multiple DSL lines by using a Cisco router and a network protocol called Multi-link PPP.
Viatel said its solution is about 50% cheaper than equivalent leased-line services and costs roughly the same as BT’s SDSL services.
