BT has recently been testing a new 1MB home user ADSL service. BT will start the offical trail on the 6th October 2003, orders can be taken now to ensure you will be one of the first to receive the service. The DataDSl Home 1000 will be an upgrade path from the 512k home product and will have a 50:1 contention ratio.
Other than that, everything else is the same as the other DataDSL services. The DataDSL Home 1000 is not rate adaptive, so not everyone on a DataDSL Home 500 will be able to upgrade.
