This read-only object reports the unit's model number, an integer between 0 and 999. This numeric code identifies which specific CDD-564 hardware variant is deployed, which matters because feature availability, like which demodulation or FEC options are actually supported, can differ between model variants sharing the same base MIB. An admin scripting an inventory audit across a satellite network would poll this object across all units to confirm which sites are running a particular hardware variant before rolling out a configuration change that assumes a specific feature set.
