Description: HDR Data Dedicated Transmission Mode (DDTM) preference: unknown(1) - DDTM preference is unknown off(2) - DDTM preference set to OFF on(3) - DDTM preference set to ON noChange(4) - DDTM preference is no change
What is c3gHdrDdtmPreference?
This read-write enumeration configures the EV-DO modem's Data Dedicated Transmission Mode (DDTM) preference, letting an admin set it off(2), on(3), leave it as noChange(4), or see it as unknown(1). DDTM affects how the device shares its radio resources between voice and data on EV-DO, so an admin would adjust this setting to optimize behavior for a data-only cellular WAN deployment versus one that also needs voice capability. For example, an admin operating a pure data-backup router with no voice use case might explicitly set this to off(2) to avoid DDTM-related data interruptions during any voice activity.
