It will not matter! But the other way round it does.

I recently changed an ADSL faceplate that had been left on an upgrade to 40/10 VDSL. They were getting around 20Mbps, changed the faceplate and it went up to around 24Mbps

It does when the end user plugs a microfilter into the BT type socket and finds his ADSL doesn't work !

ISP support staff and printed user information can sometimes handle the ADSL 1.0 type SSFP but as yet don't expect to meet an RJ11 socket top centre of the faceplate. Caused me a boring trip across East Anglia.

I recently ordered 8 pstn lines to be used for broadband.

The open reach engineer fitted the vdsl plates for me even though it's for non fttc use. I wasn't complaining. Suits me fine.

Sure, it's no big deal for anyone that understands, but all the retail ISPs send out instruction sheets or have online materials that are oblivious to this, leaving the end user plugging a microfilter into the voice socket.
