Discussion topic: Noise Margins?

I'm curious to know what is a good noise margin to have and what level I need to worry about and be needing to investigate further.

I'm currently showing 11.5 dB.

@AshPion Sky's target is usually 6db for stability and speed, some lines can go down to 3db but that can cause instability.

Yours is higher but it's nothing to worry about as you are syncing at the maximum speeds available on a fibre to the cabinet connection.

@AshPion

The fastest speed in the uk is 80Mbps . In your case whilst looking high if they where any lower then the line may become unstable. In the rest of europe faster speeds than 80 are obtained by supervectoring which openreach never introduced in the uk
