This is the mirror of grantEntitlement: setting it to a channel's channelId revokes that customer's entitlement to the channel in a single lightweight SNMP SET instead of rewriting the untimedEntitlements1/2 bitmap. An operator processing a mass cancellation, such as a premium sports package expiring for many subscribers, would SET this object per customer rather than issue a full bitmap update, saving significant management-plane traffic across the access network. Setting revokeEntitlement to the same channelId used when granting access to a discontinued premium channel would cause the OLT/ONU to clear that channel's bit in the customer's entitlement bitmap.
