hairy1: I am currently with Vodafone.
It is just a change from ADSL to VDSL.
The weird thing is the existing modem gets an ADSL sync. It just doesn't connect....
Were you on the Red network before, do you know? Switching from our Red network to VDSL requires major provisioning changes, your connection at the exchange is being physically moved from one set of equipment to another and your old port will be decommissioned. Although I would have thought if that were the case they would only relinquish your MPF line once the VDSL install is complete. Let me know if you want me to check this out for you!
