Started Unicast Maintenance Ranging - No Response received - T3 time-out

This indicates a problem on your upstream connection. Confirm that all connections are tight. Replace interior cables with brand new high quality RG6 if practical. Remove all unnecessary splitters. If problems persist, contact Cox and request a tech visit as T3 timeouts are often caused by problems outside the boundaries of your property. Post your modem signals and full logs for more complete advice.
No. It indicates a lack of response from the upstream server to a request from the modem. Repeated requests without a response leads to a failure.
Uh, not sure why you're downvoting when I'm trying to help. That's technically true bit it makes it sound like there's a problem with the Cox CCAP. If your modem sends several RNG-REQ messages without receiving an RNG-RSP message it logs a T3 timeout. If the whole CCAP was down you'd see a complete loss of connectivity. The reason the modem isn't getting a RNG-RSP is because the RNG-REQ is never getting to the CCAP. This is almost always due to noise on the upstream which only a Cox technician can fix.
Or it does get there, but CCAP does not respond.
