Standard BT ADSL faceplate do it need upgrading if a customer upgrades to VDSL?
I was wondering if there is any difference in the filtering?
A new filtered face plate will be fitted to the master socket which will do away with the need to have filters on any telephone extensions that you may have.
It only filters the phone side of the circuit (low pass filter), so the ADSL/VDSL simply passes through unaffected. So it does not matter which type you use.
