For the technical guys here.
I saw some strange behaviour on my VDSL line this morning.
The SNRM both up and down jumped up a notch but remained extremely level with no uptick in FEC / CRC errors.
I'm struggling to understand - maybe interference, or DLM playing around ?
Looks too uniform to be interference ?
Cheers
