Yes but there's a difference between an engineer at the exchange (ADSL) or cabinet (VDSL/FTTC) and one requiring a visit to the customer's premises.

[pedant mode] BT Openreach or a subcontractor (Kelly etc.) [/pedant mode]

In reply to a post by MrSaffron:

A router with ADSL modem, and an Ethernet switch where one port can be reconfigured to operate as an Ethernet WAN port to be precise, and thus interoperate with Openreach GEA FTTC and FTTP products.

But yes people need to be clear when saying a device supports VDSL, as can see lots of people moaning that the plug fits but nothing works.

So something like that thing that Plusnet supplies? But the thing that Plusnet supplies is just a ADSl router/modem with a knocked up firmware.

Oh dear, if they start doing that watch for even more complaints. I think I would wait for a while before I even tried it to be honest.

As things stand, but there are trials underway ahead of a launch where the engineer does not visit the customers home

What if thing go wrong on the day of broadband installed?

Contact service provider and if necessary arrange an appointment , just like an ADSL provide .

What are they doing: also sending vdsl Interstitial faceplates with the option of data extension kits if required?

I would hope they are doing that, but they may not be

More likely to be a micro-filter suitable for use with the VDSL service?

There is a router in the trial stages so it might be that but I feel it's more likely to be some kind of mis-communication. Although it is entirely possible.
