Re: 55 DbmV upstream power level

This confuses me a bit how a bad downstream SNR would cause the upstream transmit power level to increase so I'll look into it a bit more and speak to someone who will know, have seen bad downstream SNR and it did not appear to cause modems to increase their transmit power.

Thank you for the information!
