Both the VDSL modem AND
the VDSL Faceplate are provided by Openreach as part of the installation.
Unlike other ADSL filtered faceplates, it uses the existing lower removable half of a standard NTE5 to sandwich together the modified assembly.
This means that you can actually hardwire telephone extension wiring to the lower half of the plate whilst your VDSL modem is on-line and operating.
Although not advertised, there appears to be provision to extend the VDSL wiring (ie the unfiltered A & B wires) to an RJ11 VDSL extension socket; in the same way as you can with an ADSLnation ADSL filtered faceplate.
