qamChannelModulationFormat
Module: SCTE-HMS-QAM-MIB
OID (symbolic): SCTE-HMS-QAM-MIB::qamChannelModulationFormat
OID (numeric): 1.3.6.1.4.1.5591.1.11.5.3.1.1.1.1.2
Node type: OBJECT-TYPE
Type: QAMChannelModulationFormat
Access: read-only
Description: RF Modululation for this output QAM channel when qamChannelContWaveMode is off.
What is qamChannelModulationFormat?
This read-only object reports the RF modulation format, such as QAM64 or QAM256, used on a QAM channel when Continuous Wave mode is off. Admins check this to confirm the channel is modulated at the density expected for its service, since higher-order QAM carries more data but is more susceptible to noise. For example, seeing qam256 confirms that channel is running the higher-capacity modulation typically used for digital video or DOCSIS downstream service, versus the lower-order qam64.
