I recently posted this
Part of it was about an issue I used to have on ADSL in that often when the phone used to ring the line would go down 99 times out of 100, this went away when I was able to upgrade to fibre, however..............
I've now realised that in the last few days whenever someone picks up the phone receiver (without it ringing or someone even starting to dial out) that the upstream noise margin plummets from the usual figure of around 6 to 1 or under (it's even gone down to 0 and caused disconnects).
Just wondering if anyone had any idea what it could be???, I've not tried it plugged into the test socket at the moment as my internet has gone down 3 times in the space of 5 mins so really don't want to disconnect again so soon and risk DLM kicking in.
As usual any help greatly appreciated.
