CM2050V T3 errors, Uncorrectables and disconnects

A couple of months ago I replaced my old reliable CM600 with the CM2050V so I could make full use of my 900Mbps plan. Since then, I have noticed that over the 32 Bonded Channels that I'm getting alot of Correctables and Uncorrectable each day, and the Error Log is showing alot of T3 and other errors. I can actually tell when this happens as I could be browsing or downloading and everything just stops for a minute or two. I've been replaced the older CommScope 2 Way splitter Comcast installed 5-6 years ago with a new one, but no difference.

Here is a copy of my Signal Strength and Error Log:

The signal stats are o/k but the error log entries indicate that something is going on. Perhaps there is noise ingress into the line(s) /  an upstream channel-return path impairment somewhere.

There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.

I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They will be able to poll the CMTS (Cable Modem Termination System) to check for any real-time degradation and / or error reports, see your node / cable plant, and modem health, and see whether or not everything is in the green zone. They can also see a history plot for the modem and poll for those upstream receive signal stats.


You should get a reply here in your topic. Good luck !

These are the signal levels without using the 2 way splitter(-3.5db).

@EG @XfinityMarcos 

I decided to add a -6db attenuator (that a Comcast tech gave me a few years ago) to lower the power level to see if that would make a difference. It did lower the power levels as expected, but still getting Correctables/Uncorrectables and T3 and other errors, see posts below:

Thank you for the update, Samuel. While looking over you account. I do want to clear up something with regard to the modems. I know you recently upgraded your modem for the internet is that the same modem you are using for the phone service. It appears so but I want to verify? 

I no longer work for Comcast.

The eMTA Modem we are using is only the Netgear CM2050V that we got several months ago. This replaced the Netgear CM600 (data only) and Arris TM822G (voice only). The TM822G is still shown on our account as a device, but it isn't connected and not in use. Only the CM2050V eMTA Modem is connected for data & voice.

@XfinityAshley I haven't had any issues with our TV service or Voice, though the voice service is from the CM2050V eMTA Modem. The data/internet service there has been times where it just "stops" for about 1-3 minutes, and after that happens, I check the Modem status, see that there are Uncorrectable and T3 error, Dynamic Range Window error.
