There shouldn't be any actual
change in ADSL2 speeds.
I'm currently sitting on a new FTTC connection with the old ADSL2+ connection still live on a different phone line (into the same cabinet). Some computers are still on the old connection so I can compare the two. Enabling the cabinet for FTTC had no effect on the ADSL2+ connection speed nor stability.
The FTTC connection is a huge improvement. Although the download speed has only increased by a factor of five (the cabinet is about a klilometre away), upload speed has improved by a factor of fifteen. Line stability has gone from about a dozen disconnections per day on ADSL2+ to none on FTTC.
I don't think there's anything you need worry about.
