stuRecvRfSrEstimate
Module: COM21-HCXSTUPRXY-MIB
OID (symbolic): COM21-HCXSTUPRXY-MIB::stuRecvRfSrEstimate
OID (numeric): 1.3.6.1.4.1.1141.3.3.1.1.4
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Received Signal S/R estimate in dB on Rf Downstream. This value is an approximation in dB. Received value should be divided by 10 to get a fixed point representation. e.g., value 185 means 18.5 dB.
What is stuRecvRfSrEstimate?
This read-only Integer32 gives an approximate downstream signal-to-noise estimate in dB, where the raw value must be divided by 10 to get the actual figure - for example a returned value of 185 means 18.5 dB. It's a leading indicator of downstream RF quality that an engineer watches for gradual degradation before it turns into outright service-affecting errors. For example, a stuRecvRfSrEstimate that has drifted down from 220 (22.0 dB) toward 100 (10.0 dB) over several weeks would flag a plant issue worth investigating before the link actually drops.
