What causes T3 timeouts?

After several service calls, I finally got all of the issues with my connection resolved. There were multiple issues including bad exterior cable and bad amplifier on the pole. Everything was great f...

    The problem with those power levels is like I was saying earlier, it's just a snapshot.  A competent Cox tech can monitor in real time what your power levels are and see if there is fluctuation.  Your issue looks pretty similar to what I was dealing with (good TX-RX power, SNR, etc) and my problem started right after Cox split one of their nodes (Vegas) to ease congestion.  That's when I removed my only spiltter (was trying to keep RX levels closer to 0) and pulled a new cable to the curb from DMARC (3rd time).  Since then, I've been rock solid.

    I will say dealing with cox help over the phone or txt is a waste of time.  You need a good tech you can talk to face to face, because it seems you have the vocabulary to troubleshoot this, you just need a tech with more/better tools.

ingress, mostly.

That matches up with the answer I found in my own research. Is there anything I can do to determine if the ingress is coming from wiring or equipment on my premises or farther up the line? It would have to be low frequency ingress since error rates on the downstream (high frequency) channels are great. No uncorrectables, and 0 to 3 correctables per day depending on channel.

    change splitters and coax. if you have tv service one downstream channel is used for tv, and you wills see uncorrectables on it.

      All coax that I can change has been changed along with from the demarc to the pole. Only thing not changed is from demarc to exterior wall jack, but the last tech said that coax was fine even though it's old. No splitters, no TV service.
