![]() This error message is DOCSIS event message is R04.0, Ranging Request. Typically, this indicates an occasional, temporary loss of service, but if the problem persists, check for possible service outages or maintenance activity on this particular headend system. The cable modem is resetting its cable interface and restarting the registration process. T4 ( Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received )Įxplanation: The cable modem did not received a station maintenance opportunity in which to transmit a Ranging Request (RNG-REQ) message within the T4 timeout period (30 to 35 seconds). Through there the App can check the signals on the modem. This error message is DOCSIS event message is R03.0, Ranging Request. I would recommend troubleshooting the modem from our Mediacom Connect App. 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. 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. This typically is caused by noise on the upstream that causes the loss of MAC-layer messages. The cable modem is therefore resetting its cable interface and restarting the registration process. Make sure the power indicators are lit, and the modem is plugged into a working outlet. Here’s how: Power status: Check if the modem has enough power. To avoid disruptions, it’s important to check the modem’s components, connections, and settings. This error message is DOCSIS event message is R01.0, Ranging Request.Įxplanation: The cable modem has sent 16 Ranging Request (RNG-REQ) messages without receiving a Ranging Response (RNG-RSP) message in reply from the CMTS. The cable modem plays a key role in internet connection. ![]() T2 ( No Maintenance Broadcasts for Ranging opportunities received )Įxplanation: The cable modem did not receive a broadcast maintenance opportunity in which to transmit a Ranging Request (RNG-REQ) within the T2 timeout period (approximately 10 seconds). This error message is DOCSIS event message is U01.0, Upstream Channel Descriptor. My question with regards to T3 errors is can the CMTS log be queried to see why it is not responding to my modem ranging requests? I understand the ranging request is communication between the two, so is the CMTS inundated with communication from modems or is my modem at fault in that it is not actually sending out the ‘hey, can you hear me?’ message?Įxplanation: The cable modem has not received any periodic Upstream Channel Descriptor (UCD) messages from the CMTS within the timeout period. I needed to look up the T errors and share them below to help other users.
