Docsis Modem Event Logs

Thanks for your time guys, I am looking for Definitions on some of these errors (or all of them if available), as it will help me do my Job a lot better. Things Like:

Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out

DHCP FAILED - Request sent, No response;

CISCO: RF disconnect,QAM lost.

And more, as well as looking for how we would troubleshoot such errors.

Thank you again for your time,
Jon

Its not that simple

Many errors like that are vendor specific and may vary.

Most of them will make sense to a CCNE and will need to be diagnostic accordingly.

would i have a better chance

would i have a better chance emails the Company that made it then? All of our modems are made by 1 of 2 companies

T counters and other errors

T4 is logged when the modem doesn't receive a ranging response

DHCP failed - that should be pretty much self explanitory

The Cisco specific event indicates a loss of the RF signal

looks like you have a modem that wasn't connected or the CMTS was down.
