Module: DOCS-IF31-MIB
OID (symbolic): DOCS-IF31-MIB::docsIf31CmtsUsOfdmaChanSubcarrierSpacing
OID (numeric): 1.3.6.1.4.1.4491.2.1.28.1.23.1.6
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 OFDMA upstream channel.
What is docsIf31CmtsUsOfdmaChanSubcarrierSpacing?
Reports, in kHz, the subcarrier spacing configured on this OFDMA upstream channel from the CMTS's perspective, tied to the channel's FFT mode (50 kHz for 2K mode, 25 kHz for 4K mode, matching the modem-side object docsIf31CmUsOfdmaChanSubcarrierSpacing). Admins use this to confirm which FFT mode the CMTS actually configured for the channel.
