Module: DOCS-IF31-MIB

OID (symbolic): DOCS-IF31-MIB::docsIf31CmtsDsOfdmChanTimeInterleaverDepth

OID (numeric): 1.3.6.1.4.1.4491.2.1.28.1.19.1.16

Node type: OBJECT-TYPE

Type: TimeInterleaverDepth

Access: read-only

Description: This attribute represents the number of samples for the OFDM Downstream channel. This is limited to 16 samples for and 32 samples for 50 kHz and 25 kHz Subcarrier Spacing, respectively.

What is docsIf31CmtsDsOfdmChanTimeInterleaverDepth?

Reports, in samples, the time interleaver depth configured on this OFDM downstream channel from the CMTS's perspective, limited to 16 samples for 50 kHz subcarrier spacing (4K mode) or 32 samples for 25 kHz subcarrier spacing (8K mode). Deeper interleaving improves resilience to short bursts of impulse noise at the cost of added latency, so admins can use this to see how the CMTS balanced noise resilience versus latency for this channel; note this is the CMTS-side counterpart to docsIf31CmDsOfdmChanTimeInterleaverDepth, whose own DESCRIPTION text is much terser about the same underlying value.
