I was on ordinary TT, owing to continual problems with DLM increasing the SNRM, I argued for it to be disabled, which it was.
But the SNRM was still wandering all over between 11dB and as low as 1.4db.
Using a very old 2WIRE router which would stay connected..just.
Now the SNRM is very stable centred on 6db.
I have no idea what the difference is between TT retail, and TT business which I assume Pulse8 use.
