Whilst trying to identify recent reasons for wild fluctuations in my noise margin and low sync speeds I have connected my Netgear 834G v3 to the test socket via a filter and my phone also in the filter. I am monitoring performance with RouterStats. When I make a phone call the noise margin drops from 14 db to 3db but recovers when I finish the call. It happens with both digital and analogue phones and on at least two filters. Sync is 2528 kbps. I have also found that when connecting the phone the margin drops to zero and returns with a lower sync and margin. Then a reboot gets the margin and sync back to previous level. Should this happen and if not am I doing something wrong? ???
It shouldn't happen, can you try another filter and, if that doesn't help, another phone?
Thanks for another lightning speed reply.
Tried a third filter and margin did not drop with the DECT or the analogue so assume I must have two faulty filters, however propose getting a Clarity faceplate as I also think my ADSLNation one has failed.
I have also found that the ex BT engineer who installed my extension had run the cable nestled up against the mains cable for nearly 2m so need to separate them. I have disconnected the extension wires at the faceplate which eliminated some noise.
Oh for a quiet line
Bright piece of work by BT again. :(
It does sound like you have had filters fail, checkout Dean's thread at:

I think you should have the router and dect 'phone as far apart as you can.
Always a good move, Rick. :thumb:
