Type: Unsigned32
Access: read-only
Description: This attribute specifies the center frequency of the subcarrier 0 of the OFDM transmission. Note that since subcarrier 0 is always excluded, it will actually be below the allowed downstream spectrum band. This is the frequency of subcarrier X(0) in the definition of the DFT.
What is docsIf31CmDsOfdmChanSubcarrierZeroFreq?
Reports, in Hz, the center frequency corresponding to subcarrier 0 of the OFDM transmission's DFT definition; since subcarrier 0 is always excluded from actual use, this reference frequency actually falls just below the real allocated downstream spectrum band. Admins mainly use this as a reference point when calculating or cross-checking the actual frequencies of specific active subcarriers on this channel.
