Unable to Decrypt Response (encrypted)

Introduction/Additional information: 

This ASM implements the Project 25 OTAR Unable to Decrypt Response message.

Usage Notes

  • This message is sent from the Mobile Radio (MR) to the Key Management Facility when a Key Management Message cannot be decrypted by the MR.
  • When the KMF receives this message, it is assumed that it refers to the most recently transmitted message.
  • This message is broadcast as a non-addressed message to reduce the message size, and to avoid issues from a relocated RSI to a different MMSI.
