Most cable modems are incapable of transmitting higher than 51 dBmV (upstream power). For example, I've read the specifications sheets for the Arris SB6183, SB6190 and TM822. They all have a maximum upstream power of 51 dBmV.Windows 2k/XP Registry Tweaks Windows 2k/XP - More Tweaks Windows 9x/ME Registry .
Yes. There appear to be some issues with errors (the correctable/uncorrectable in the report) on the downstream frequencies, specifically 591 MHz.

What cable modem signal levels are considered good
As Arris has mentioned, the target ONT upstream power is ~45dB, because this is in the best operating range of the ONT. You could add a 12dB RF attenuator at the input to the ONT, but .To comply with the FCC RF exposure compliance requirements, the separation distance between the antenna and any person’s body (including hands, wrists, feet and ankles) must be at least .All DOCSIS cable modems require that the RF signals fall within a very specific range to be an acceptable level for the modem to operate properly. These levels apply to all SURFboard .

They all have a maximum upstream power of 51 dBmV. By accessing the tiny little web server hidden inside your modem and reading the diagnostic pages, you can learn a ton of things about your modem and connection like general status, signal strength, and event history via the system log.Cable Modem RF Signal Specifications. All DOCSIS cable modems require that the RF signals fall within a very specific range to be an acceptable level for the modem to operate properly. These levels apply to all SURFboard cable modems and cable modem/gateways. Yes. There appear to be some issues with errors (the correctable/uncorrectable in the report) on the downstream frequencies, specifically 591 MHz. Correctable errors are just as they say, correctable, however, you don't want too many correctable. And if you have uncorrectable errors, you have problems.
Acceptable ranges are about + to - 10 dBmV depending on the cable company. SNR above 40 is excellent. Anything below 35 is iffy. You want to be close to 0 on the corrected column. Those 15’s are really nothing to worry about even more so because of the 0’s across the board on the uncorrectables. I am getting the following which I assume are pretty high. I have no connection problems however, and speedtest reports correct speeds for my tier. Downstream Bonded Channels. Channel ID. Lock Status. Modulation. Frequency. Power. SNR/MER. In DOCSIS, a device at the cable operator’s headend call the CMTS or Cable Modem Termination System, is responsible for managing hundreds or thousands of cable modems residing in subscriber’s homes (aka you and me).
As Arris has mentioned, the target ONT upstream power is ~45dB, because this is in the best operating range of the ONT. You could add a 12dB RF attenuator at the input to the ONT, but then your downstream receive levels would be below the ONT operating range (-10dB to +10dB, typical).To comply with the FCC RF exposure compliance requirements, the separation distance between the antenna and any person’s body (including hands, wrists, feet and ankles) must be at least 8 inches (20.3 centimeters).
All DOCSIS cable modems require that the RF signals fall within a very specific range to be an acceptable level for the modem to operate properly. These levels apply to all SURFboard cable modems and cable modem/gateways. This document describes how to verify the cable signal levels. To Verify Signal Levels
