Module: RDN-CMTS-MIB
OID (symbolic): RDN-CMTS-MIB::rdnRQuerySigQMicroreflections
OID (numeric): 1.3.6.1.4.1.4981.2.2.15.1.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The last polled value of the CM's docsIfSigQMicroreflections MIB object, which is its estimate of the total microreflections including in-channel responses perceived on the upstream interface, measured in dBc below the signal level.
What is rdnRQuerySigQMicroreflections?
Read-only integer (0-255 dBc) giving the modem's last-polled estimate of total in-channel microreflections perceived on the upstream, measured in dBc below the signal level. High microreflection values point to impedance mismatches or cabling issues in the plant causing signal echoes.
