If an incoming call fixes the broadband where is the fault?

From time to time my broadband connection will start to drop repeatedly as often as every ten minutes, then after a while it will be fixed.  Upstream SNR will vary from 25dB to 0dB, see attached routerstats trace.
After monitoring with Routerstats for a while I realised that an incoming call fixes the SNR problem, which then stabilties at 25dB, which it will hold for days on end.
Does anyone have any suggestions why/how the call fixes the line?

Re: If an incoming call fixes the broadband where is the fault?

I was making the question on this thread narrower to see if anyone had experience to add.  As you say on the other thread it was suggested that the ringing voltage possibly fixes a poor connection in the line.  That does not say where the fault is, nor does it add much explanation as to how it gets fixed by the voltage.  I was hoping someone might have something interesting to add.....
