Started Unicast Maintenance Ranging no Response received. T3 time-out.
Explanation The cable modem is online and has sent 16 periodic Ranging Request (RNG-REQ) messages without receiving a Ranging Response (RNG-RSP) message from the CMTS within the T3 timeout periodic. The cable modem is therefore resetting its cable interface and restarting the registration process. This typically is caused by noise on the upstream that causes the loss of MAC-layer messages. Noise could also raise the signal-to-noise ratio (SNR) on the upstream to a point where the cable modem's power level is insufficient to transmit any messages. If the cable modem cannot raise its upstream transmit power level to a level that allows successful communication within the maximum timeout period, it resets its cable interface and restarts the registration process. This error message is DOCSIS event message is R06.0, Ranging Request.
Recommended Action Check the upstream transmit power for the cable modem to see if it is at or near the maximum allowable levels. Check the RF plant for cabling or connector issues that could generate sufficient noise to lose MAC-layer management messages. If using a Cisco CMTS, you can use the show cable flap-list command to determine if other cable modems on the upstream are having problems. You can also use the show interfaces cable upstream command and examine the noise, microreflection, and uncorrectable error counters to determine the level of noise on the upstream.
