Access: read-write
Description: This attribute is the Subcarrier index corresponding to the frequency at the start of the spectral notch.
This value can only be changed while the value of 'docsPnmCmtsDsOfdmNprEnable' is 'false'. An attempt to set this value while the value of 'docsPnmCmtsDsOfdmNprEnable' is 'true' will return 'inconsistentValue'.
What is docsPnmCmtsDsOfdmNprStartSubcar?
The subcarrier index (0-8191) marking the start of the spectral notch the CMTS creates for Noise Power Ratio testing; can only be changed while docsPnmCmtsDsOfdmNprEnable is 'false'. An admin sets this along with the stop-subcarrier to define a deliberately excluded band used to measure in-channel noise floor via the NPR technique.
