We had yet another engineer visit Thursday.
He couldnt find any problems with his JDSU test equipment.
He did fit another filter in the back of the master socket.
He also replaced corroded crimps in inspection pit just outside our property.
Unfortunately the problem is still not fixed
We had a little drizzle this morning and noise on the phone was terrible for about an hour before returning to normal.
SNRM for the broadband was bouncing up and down too but no disconnects this time.
Recording of noisy line this morning just after it stopped drizzling:
