What is the reported status of a modern key after it has been loaded in the End Cryptographic Unit?

When a modern key has been loaded into the End Cryptographic Unit, its status is indicated as "Filled end equipment." This designation shows that the key is not only present in the device but is also ready for use in cryptographic operations. The process of loading the key into the End Cryptographic Unit usually signifies that the key has completed all necessary steps to be made operational, ensuring that secure communication can commence.

Labels such as “Pending” would suggest that further action is needed before activation, while “Active” implies that the key is currently being used, which may not necessarily mean it has been loaded successfully. "Not usable" clearly indicates that the key cannot be utilized, which does not align with what it means for a key to be loaded and filled into the equipment. Thus, the phrase “Filled end equipment” accurately reflects the operational readiness and proper state of the key after it has been successfully loaded.
