Re: 55 DbmV upstream power level
They can fit attenuators to boost or reduce the power levels.
I stand corrected, attenuators are for downstream power levels and SNR.
The friend who corrected me knows their stuff, so I'll take their word for it.
Another edit after quick tutorial from said friend, the upstream can be adjusted by an attenuator.
This would usually happen at the cab, but if low downstream SNR is causing the upstream power level to increase to be heard by the ubr, fitting an attenuator would fix the SNR issue, lowering the upstream power level.
