Have just had the faceplate off, in the bottom left corner it says "ADSL v1.0". You can see a picture of it here
It is the second from the bottom
Tried the router in the master socket behind using the "hpm-120 splitter" that came with the TP-Link VR900. The sync speed was actually slightly slower than with the faceplate attached so I think whilst it is not helping it is not the only cause of problems.
That is one of the tests that Zen asked me to tick off before they send an Openreach engineer out, I am guessing that they will fit the latest filter system will they if and when they come out.
There are no extensions plugged in anywhere, it is just a telephone extension lead with the telephone attached but the test I did, did not have that attached.
