[Signals] Loss of upstream channel bonding

Click for full size
Click for full size
I was noticing some cutting out on the music choice channels this morning (as I listen to them in the overnight) but then I checked the modem later this afternoon and I noticed that I had lost upstream channel bonding. This is in Springfield MA. The modem is an Arris CM 820. I have the 50/10 speed tier. I am wondering if this is a sign of problems to come. I also noticed a higher than normal amount of uncorrectable codewords.

Western Mass Electric tree contractors were out trimming the trees around the lines and the overhead cables next door go underground and feeds the pedestal that feeds my cable. I am wondering if they could have damaged the lines.

Update: Truck roll scheduled. Comcast CS could see the issue. I am wondering what the tech should look for.

The level on your one US channel looks great, so I don't suspect anything related to the signal level. Have you tried rebooting the modem? That has worked for me when US bonding drops and doesn't come back on its own.

T3s & T4 certainly point to plant issues.
If they were doing tree maint in the area, could very well have messed up your drop, could be as simple as a loose connector.
If your problem persists I'd certainly call in a ticket.

What about the uSNR as gar187er See Profile stated. This can't be read at the modem and may be an issue regardless of the forward signal stats.

But I wonder how that call would go? I imagine it would be very frustrating to go through the rigamarole to clear cookies, plug directly into CM, etc. But if IowaCowboy See Profile has the patience for it, it might work. Although I wonder if they will see it as a "problem", given the upstream power is ok. But if the uSNR is bad, they could see that and potentially roll a truck I s'pose.

I'll meet you over at Iowa's house to help you break in so you can reset the modem.

Just had the tech over, DOCSIS test failed at the tap. They are going to have to run some more tests in the morning outside as the techs meter died.
