Re: Evidence of 8 Downstream Channel Bonding - Post Here

said by EG:

I'm so glad that I purchased this 8 X 4 modem !! Looks like the power levels just need a "little" more balancing. Performance is terrific !!

Yeah when I got 8 downstream the power levels went up to about 10-11dBmV.
They did bring them down to 5-6 , but now my upstream power level went from 44 to 51.

FWIW, I was more referring to the balance (within 2-3 dB) between the multiple bonded carriers rather than the overall total power.

More than 5 dB diff between some channels but the "uncorrectables" are not really spiking much. No packet loss either.
