The SNR threshold is used to determine if a channel is capable of 
operating error free in the modulation mode that is specified for 
data IUC in the configured modulation profile for the upstream 
receiver.
              
A default SNR threshold is used for each modulation type. 
The operator can override this by configuring a different SNR 
threshold for a specific modulation type that is used in the 
primary or secondary modulation profile.
              
This threshold is used to transition channel states.
              
SNR thresholds are configurable with a resolution of 1dB.
              
The following  table lists default SNR thresholds for the
different modulation modes, with no FEC:
              
        QPSK                        16dB
        8QAM                        19dB
       16QAM                        22dB
       32QAM                        25dB
       64QAM                        28dB
       128QAM                       31dB
       256QAM                       34dB
