I expect that be of aid

T4 Timeout

Once the modem is online, the CMTS sends Periodic Ranging or keep-alive requests to it every
30 seconds. If the modem doesn't receive one, a T4 timeout occurs. Once 16 of the T4
timeouts have occurred, the modem resets.
If there is a downstream communication problem, the cable modem might not receive these
keep-alive requests. If the upstream utilization is too high, or too many modems are connected
to the same upstream port, it is possible that some modems will not get the required
bandwidth or transmit opportunities to respond to the keep-alive requests. Either of these
issues can cause T3 or T4 timeouts to occur.
