hcxPortRealTimeMeanNoise
Module: COM21-HCXRX-MIB
OID (symbolic): COM21-HCXRX-MIB::hcxPortRealTimeMeanNoise
OID (numeric): 1.3.6.1.4.1.1141.2.32.1.1.28
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This attribute provides a realtime mean noise level in dBmv. It is updated every approx 5 seconds and provides a snap shot of the noise conditions on this receiver port.
What is hcxPortRealTimeMeanNoise?
This read-only Integer32, updated roughly every 5 seconds per the description, provides a near-real-time mean noise reading in dBmV for this receiver port. Unlike the 15-minute bucketed values, it gives the admin a live snapshot suitable for watching noise conditions change during an active troubleshooting session. For example, while a technician taps a suspect cable connector, the admin watches hcxPortRealTimeMeanNoise for an immediate jump that confirms the connector is the noise source.
