Module: DOCS-IF31-MIB
OID (symbolic): DOCS-IF31-MIB::docsIf31CmDsOfdmChannelPowerRxPower
OID (numeric): 1.3.6.1.4.1.4491.2.1.28.1.11.1.3
Node type: OBJECT-TYPE
Type: TenthdBmV
Access: read-only
Description: This attribute provides an estimate of the average power measured at the F connector input of the CM in the receive downstream channel set for this 6 MHz band.
If the band index is 0, then this attribute provides an estimate of the average power measured at the F connector input of the CM for a 6 MHz encompassed spectrum containing the DOCSIS 3.1 PLC at its center.
What is docsIf31CmDsOfdmChannelPowerRxPower?
Reports, in tenths of a dBmV, the modem's estimated average received power at its F-connector input for this 6 MHz band of the downstream OFDM channel; when the band index is 0, this instead reports power for the 6 MHz band centered on the DOCSIS 3.1 PLC. This is one of the primary downstream signal-level readings admins check when diagnosing weak or overdriven downstream signal on a cable modem, similar in spirit to legacy downstream power readings but broken out per 6 MHz band across the wide OFDM channel.
