Description: Signal/Noise ratio as perceived for upstream data from this MTA. If the Signal/Noise is unknown, this object returns a value of zero.
What is rdnIfCmtsMTAOnlyStatusSignalNoise?
Read-only value in tenths of a dB giving the upstream signal-to-noise ratio perceived from this MTA, or zero if unknown. A low SNR on the voice module specifically can explain choppy or dropped VoIP calls even when the modem's own data connection seems fine.
Examples
