If there is a "dummy's guide" to "frequency bins" & "power masks" et al
- do please post a link!
Meantime, in my blissful ignorance, I still feel this is much simpler - and the chat I had with one of the BTCare Mods this eve tends to confirm this. He explained to me (again) about DLM, and that it seeks out the highest most stable level, and that therefore my 3Mbps Up is simply that.
, I argued, my line has never been tested with the 6/7Mbps Up that the engineers think it should be well capable of. After the installation it sat consistently at precisely 1.00, after the first reset at 1.6, and after the third reset at 3.00. It was perfectly stable, so did not need to "settle" to a lower rate. Just stayed rock solid at the start rate, hour in hour out. As far as I can see, the DLM system never tried anything higher
. Because, I tend to think, nobody is bothered much about Up, so it just fixes at a safe level. If somebody (like me) persists, and the computer is kicked (to use a technical phrase) then DLM bumps up another safe notch. But, I feel, never truly tests for the highest possible Up as it seems to do for the Down. No doubt algorithms are responsible as they are for most modern life!
So I just want the DLM computer to be politely asked to just try
offering a 7Mbps Up and see what happens! From all the evidence of the last weeks, I would bet a kilo of copper that it would be very happy and stable - and then so would I!
Anyway, I understand my naive theory is going to be addressed by Openreach next week, so I will keep you in touch with any developments!

and am happy to post anything else that might help, even PM you my number etc.
