Well, actually no. I've had no Downstream ES yet and the SNR Margin is very stable, of course if the line became unstable it would resync and connect back at a SNR Margin of 6 dB, but I have no intention of performing a manual power down for 30 minutes. The line is perfectly stable currently and the SNR Margin has always been stable, just has the normal swings day-to-day.
Seems good currently:
