Are you ex-Telewest or ex-NTL?

Downstream SNR, above 30 is preferred, 28ish being the lower limit (i think)

Downstream power should be as close to 0 as possible, with the limits being -6dbmv to +12dbmv

Upstream power should be no lower than around 32dbmv and no higher than 58dbmv. If you are on QAM16 the power level should not be higher than +55dbmv.

DS I wouldn't have it higher than +10 ... field runs with -10 - 10 across the board .. but it depends who you speak to ...
