Hi again Magicone,
I'm sorry I didn't have sufficient time to research the topic earlier.
What I was suggesting is to exchange (but N.B. retain the original for BT use) the almost totally locked down BT Huawei Echolife HG612 modem for another VDSL2+ compatible one.
Firstly obtain the username (no password required) in the advanced settings of the home hub (bthomehub@btbroadband.com).
Then substitute a different VDSL2 modem using the IP address from the WAN side.
Hopefully you will be presented with a screen then of 'BT Wholesale Service Information' such as (
http://194.74.65.98/index.html) in a browser window.
The settings for the Draytek 2820VN are suggested as:
WAN 2 : PPPOE - Enable
ISP Access Setup Username: bthomehub@btbroadband.com
WAN Connection Mode Detection - ARP Detect
MTU - 1442 or possibly 1492 or 1500
PPP/MP Setup - Ensure No (Dynamic IP) is selected
All other settings are as they are out of the box.
There is a useful thread here:-

http://community.bt.com/t5/BB-in-Home/MTU-setting-for-BT-Infinity/td-p/29863N.B. I have edited and extrapolated the above notes from the links mentioned as a first draft and without access to any BT Infinity service.I hope others here might provide further ideas or better instructions as it's obviously going to become important.
IMHO it is quite disgraceful that end users with an understanding of modem technology are prevented from examining the modem statistics to assist in line improvement.
It seems as if the expected "solution" is to prohibit the use of a VDSL2+ service if it can't achieve the minimum specification **, rather than attempt proper repairs.
Given the condition of many of the longer lines, a genuine attempt must be made to improve them or else others must provide full FTTP instead.
** Furthermore many BT O Engineers will be familiarising themselves with the real-world effects of this new technology and I'm disappointed that other sources of help seem to be deliberately excluded.
Perhaps the situation will improve once a few more solutions such as those from Vtesse Networks and Rutland Telecom are commissioned?
Kind regards,
Walter
(P.S. If any in Cotton Park Rugby are fed up waiting for the twice times delayed Infinity product, there is probably a readily available substitute for them !)
