This is a trigger object: setting it to the channelId of a channel grants that customer entitlement to the channel without the overhead of an SNMP SET against the large untimedEntitlements1/2 bitmap, per the description explaining this exists specifically to reduce management traffic. Note the odd choice of IpAddress purely to carry a 32-bit channelId value, not an actual network address; an admin scripting bulk entitlement grants, such as unlocking a sports package for thousands of customers, would SET this single object per customer instead of rewriting the whole bitmap each time. Setting grantEntitlement to a specific channelId would cause the OLT/ONU to automatically flip the corresponding bit in that customer's untimedEntitlements1/2 bitmap.
