These power levels ok ?
 

My areas finally been finished after some capacity upgrade work. Ive left it a week as they might have been finish off a few things. It went down on Sunday for about 20 mins and the power levels had changed a couple of notches.

These ok or is it worth calling out the tech to tweak them?
Also i find it odd that its connecting to 26,29,30,31 - why the strange 2 number gap ?

They seem OK to me. Are you getting any problems? If not dont worry.

I have a slight oddity at the moment. Have never seen this before.

The speedtest is still perfect though at 30Mbit.

@arcimedes

As you've noticed, DS3 is unstable with an untenable SNR. Others might agree if it's working OK don't worry, but it isn't working OK and there shouldn't be so much DS noise that the channel doesn't function properly. It will give you gyp.

Thanks for the comments I have posted the data on the VM forum. I dont want to re-boot the shub in case it doesnt come up;)

We'll see what comments there are.
