BT Wholesale as expected is to rollout SDSL (Symmetric DSL) beyond London in two stages initially. March 2003 will see 28 additional exchanges supporting SDSL and April 2003 will see another 150 added to the list.
The rollout will result in a mixture of ADSL and SDSL at the exchanges, since it would appear that BT are to deploy SDSL on the existing Fujitsu FDX DSLAMs. Symmetric DSL will appeal to business's looking to do things like having home workers VPN in across the Internet, since the increased Upstream bandwidth means the lines can cope with more users.
The challenge is now firmly on for BT's competitors to offer similar services outside of the London area, otherwise we may see BT becoming the dominant player in the SDSL market also.
