What is docsIf31CmtsDsOfdmChanLowerGuardbandWidth?
Reports, in Hz, the width of the lower guardband configured on this OFDM downstream channel, valid as either 0 (no guardband) or 1 MHz to 1.77 GHz. Guardbands are unused spectrum buffers at the channel edges that protect against interference from adjacent services; admins can check this to understand how much spectrum is being reserved as a buffer versus used for active subcarriers on this channel.
