Description: The signal to noise ratio perceived for this cable modem on the upstream logical channel as of the last station maintenance.
What is docsIfExt2CmtsCmMscStatusMeasuredSNR?
This value, in tenths of a dB, reports the signal-to-noise ratio the CMTS measured for a specific cable modem's upstream logical channel at the last station maintenance. An admin watches it per modem to catch upstream RF degradation for that subscriber before it causes packet loss. A dropping SNR reading over successive polls on one modem points to a developing plant or wiring problem for that customer.
