Recieving T3 Time outs, Event type Codes: 5, 16 and 24 intermitten disconnects from internet

Hello, I've been trying to diagnose a long standing internet problem at my residence. I've currently replaced modems, routers, and cables from desktop to the wall. Last being the coaxial cable from the receiver on the side of the house. My internet will intermittently disconnect for roughly 5s or so and reconnect at random points throughout the day. Checking my Modem's event logs I'm receiving several error codes. Shown below, I've removed the CMAC addresses out of privacy.

So I have reason believe this is a higher level issue and possibly an issue at the node, how would I go about getting this remedied?
