I’ve started to see some regular variations in my SNRM. Something is affecting DS for about an hour overnight causing DSLstats to send me alarming emails that my SNRM has dropped to very low values, but recovers after about 1 hour. This has happened during the last 8 nights, but only to this extent on one of my lines, there is a tiny dip in the other line’s SNRM at the same time.
As it’s happening overnight it isn’t causing any issues for me, but I am curious as to what might be causing this. I’m in a rural village with no heavy plant as far as I now, although there is a sewage pump at the end of my drive, but it’s been there for years.
There are also swings on the US SNRM, but during the day and pretty much mirrored on both lines which seemed to start around the time the FTTC capability was increased in the cabinet.
Any thoughts on this?
