Noted last night that I have had US & DS SNRM step changes (decrease) on my VDSL2 line which have occured without a re-synch, would have thought that such SNRM step changes would be the likely to be the product or bi-product of a line re-synch, for whatever reason.
Not complaining, hence the post in "BB Technology" as opposed to "FTTC and FTTP Issues" forum, this is the first time I have achieved a 3dB DS SNRM target since migration from ADSL to VDSL in June 2018, just curious how the changes came about without a line re-synch.
DSLStats snapshots attached for reference, note, they are on a 4 day "X" axis.
Edit: Axis correction
