I think in general the line attentuation limit for 1mb and 2mb services is
45db... or 41db if you already have a 512k product on the line. Check your
router to see if it gives you these line attentuation stats.
However, even if you're within the db limits, there's no guarantee that your
router's readings are the same as BT's. The line checker says you can get
the service but then that's no guarantee either

!
Only way forward is to order it and see what happens. If you can't get it,
nothing happens - you stay on the exisitng product and don't pay anything.
Not sure what happens if you migrate from one ISP to another and upgrade at
the same time though. I would hope they prospective ISP would tell you and
let you decide if you want to contiune the migration.
