Description: Signal/Noise ratio as perceived for upstream data from this cable modem. If the Signal/Noise is unknown, this object returns a value of zero.
What is docsIfCmtsCmStatusSignalNoise?
This OID reports the signal-to-noise ratio for upstream data transmission from a cable modem. It measures how clean the signal is—higher values indicate less electrical interference. A cable technician checks this value when diagnosing why a modem's connection quality is degraded.
