Perhaps Black Sheep (or licquorice or . . . ) would please comment?
Yes I hope so.
I was thinking about the REIN team how they are monitoring my line while they are doing tests.
You can see that they did two copper line tests on this graph maybe from the exchange.
Only just seen this thread.
Hmmm. That looks a bit odd to me. Not heard of them doing tests such as that .... especially out of hours. Why or even how would they do something to cause a dip in the snrm.?

The suite of tools available to isps was called woosh. Some of the tests are pretty basic with the latest addition being the CIDT and part of the newer KBT suite. I'm not at the pc atm as i have a copy of some kbt tests that i got plusnet to run for me so i coukd see what they look like.......but I'm sure there's a copy of the old version of the woosh handbook available if you do a google search which should give you an idea of what was available. From memory I think it was called the one shot test which isps used most frequently. Some tests may be what they call intrusive and will disconnect the EU, but most aren't.
AFAIK the info is mostly about line info and dlm type info. It checks if the line is OK between the SP and the ras. And also to the dsl am. I'm sure they base anticipated speed on attenuation.... in fact most of the info is based on info obtained from the modem. Ie hlog and qln to detect hr and crosstalk.

Sorry really battling to type this on a mobile device as it's wanting to correct a lot of words and abbreviations which it doesn't recognise.
