True but had i left it at 5.1 it would have dropped by another db today then another the day after and a resync would have occured... a few of these and ip profile is affected (IMHO).
But wouldn't a prolonged test such as that actually confirm beyond any doubt that there is still an ongoing issue/fault that experienced engineers would be able to easily diagnose & hopefully repair?
Such similar symptoms as SNRM graudually dropping over a number of days, disconnections when using the phone etc. were resolved on my connection via a combination of replacing the SSFP (my own test with a dangly filter identified that it was faulty) & remaking a connection in the DP at the top of the pole across the road from my house.
TBH, I believe replacing the SSFP had the greater instant impact & remaking the DP connection has hopefully finally cured my connection's general, but ongoing intermittent instability issues.
Gradually dropping SNRM suggests (to me) that resistance is gradually building over a number of days, only being "released" by physically rebooting/disconnecting & reconnecting the modem.
My SNRM used to immediately increase by quite a few dB when whatever was causing the issue was "released" by the telephone ringing pulses when dialling in.
Sometimes this would also cause an immediate connection drop, with things returning to normal for a few hours at a time.
FWIW, see my attached 8 day graphs.
The before & after conditions are clear to see.
There has only been one connection resynsc that was not initiated by me.
That was when DLM decided that my connection is now sufficiently stable to turn off Interleaving, INP & delay (unless it is just lulling me into its regular false sense of security that it has had so much fun with over the last few months.
DS error seconds have increased (to be expected I suppose, due to Interleaving being turned off)
DS Output is also fluctuating more than what I would class as "normal".
Other than those, it all looks quite promising.
If my connection is indeed now permanently fixed (a couple of weeks monitoring will confirm one way or the other), it will just show how inadequete the fault finding efforts of the previous visiting engineers have been.
Have you tried the ongoing graphing scripts yet?
They can be a lot more revealing (& useful when trying to "prove" that fault conditions still exist than trying to study numbers in a chart/list.
