The VDSL2 faceplate is interstitial, see the pic on this page
. The phone line at the bottom is plugged into the pre-existing faceplate. (That is filtered by the VDSL section, so in theory unless that fails your wiring is isolated).
The general belief, including that of (I think all) the long-standing OR engineers here, is that there is no real difference between the filtering in the VDSL2 faceplate, any ADSLx faceplate, or an ADSLx dangly filter. It seems to have been introduced (to replace the BT ADSL filtered one)purely to speed up the installation process, as it just needs inserting in the same way as the iPlate, without the extension wiring needing to be transferred.
So, if desired, just remove the whole lot and use the test socket as before, with or without a dangly.
