rdnRQueryCmtsCmDownChannelPower
Module: RDN-CMTS-MIB
OID (symbolic): RDN-CMTS-MIB::rdnRQueryCmtsCmDownChannelPower
OID (numeric): 1.3.6.1.4.1.4981.2.2.15.1.1
Node type: OBJECT-TYPE
Type: TenthdBmV
Access: read-only
Description: The last polled value of the CM's docsIfdownChannelPower MIB object, the received downstream power level at the CM, in TenthdbMv. DOCSIS specifies this to be between +5.0 and - 15.0 dBmv.
What is rdnRQueryCmtsCmDownChannelPower?
Read-only value in tenths of a dBmV giving the last-polled downstream receive power measured at the cable modem (mirroring the modem's own docsIfDownChannelPower); DOCSIS specifies a valid range of roughly +5.0 to -15.0 dBmV. Admins use this to spot a modem receiving too weak or too strong a downstream signal, a common cause of intermittent connectivity.
