Module: DOCS-IF31-MIB
OID (symbolic): DOCS-IF31-MIB::docsIf31CmtsCmUsOfdmaChannelRxPower
OID (numeric): 1.3.6.1.4.1.4491.2.1.28.1.4.1.1
Node type: OBJECT-TYPE
Type: TenthdBmV
Access: read-only
Description: This attribute is the total received power in a specified OFDMA channel, normalized to power in a 1.6 MHz bandwidth, at the RF input port of the CMTS for a given CM.
What is docsIf31CmtsCmUsOfdmaChannelRxPower?
Reports, in tenths of a dBmV, the total received power the CMTS measures from this modem on a specific OFDMA upstream channel, normalized to a 1.6 MHz reference bandwidth. This is one of the core signal-quality metrics an admin checks when diagnosing weak or noisy upstream signal from a cable modem, analogous to upstream power readings on older DOCSIS channels but normalized for OFDMA's wider spectrum.
