Module: DOCS-IF31-MIB
OID (symbolic): DOCS-IF31-MIB::docsIf31CmtsDsOfdmChanSubcarrierSpacing
OID (numeric): 1.3.6.1.4.1.4491.2.1.28.1.19.1.11
Node type: OBJECT-TYPE
Type: SubcarrierSpacingType
Access: read-only
Description: This attribute defines the subcarrier spacing associated with a particular FFT mode configured on the OFDM downstream channel. If it is 4K mode, then the subcarrier spacing is 50kHz. If it is 8K mode, then the subcarrier spacing is 25kHz.
What is docsIf31CmtsDsOfdmChanSubcarrierSpacing?
Reports, in kHz, the subcarrier spacing configured on this OFDM downstream channel from the CMTS's perspective, tied to FFT mode: 50 kHz for 4K mode, 25 kHz for 8K mode. This is the CMTS-side counterpart to docsIf31CmDsOfdmChanSubcarrierSpacing, which admins use to confirm which FFT mode the CMTS actually configured for this channel.
