Why do I have so many Uncorrectables?

Sometimes the reasons for these Cable Modems to see some Uncorrecatables would be caused due to problems and errors that you might be having on the cables. ... You should understand that the reason behind these uncorrectables is something wrong with the cable or the modem you might be using.

What should my cable modem signal levels be?

Ideal levels are approximately 40 to 50 dBmV for single channels, 37 to 48 dBmV each for 2 to 4 channels. The Signal to Noise Ratios should also all be within three dB of each other. However, for power level -15 to -6 dBmV the SNR should be 33 dB or higher and for -6 to +15 dBmV the SNR should be 30 dB or higher.

What should the SNR be on a cable modem?

SNR is best over 30, (the higher the better, might work well with as low as 25 at times). Anything less than 25 will cause dropped connections, packet loss, slow transfers, etc.

What is extended upstream transmit power?

The term extended upstream power was coined to allow modems to transmit at higher powers, even exceeding those established for single channels. ... Extended upstream power allows modems to send at powers up to 61 dBmV per channel.

What is a T4 timeout?

T4 Timeouts result when a CM does not receive a Station Maintenance Opportunity in which to transmit a Ranging Request within the T4 timeout period which is approximately 30 seconds. T4s typically result from an impairment in the downstream.
