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.
