Over the last few weeks I have noticed that my up-stream SNR Margin graphs when the phone is used drops.
This is with the HG612 plugged in the test socket or NT5 face-plate.
This up-stream graph (green) shows I used the phone three times between 15.00 and 16.00
On the down-stream at 19.30 that's when my ISP did some tests.
Is this the signs of a HR joint. ?.
My ISP has done a copper line test last week and said it was ok.
A Quite line test is mainly ok but I have heard the odd crackle also last week when I lost Dsl for 15hrs I could hear my modem trying to do a 'Handshake', it was very quite though.
If I do a ring back test, wait till it times out and the tone has stopped I can hear more back ground noise, not sure if that's a good test though.
