This indicates detection of the Direct Message Profile protocol.
The Direct Message Profile protocol is specified in STANAG 4406 Annex E. It is a compact format used for transmitting time critical short X.400 messages (X.420 and STANAG 4406) on low bandwidth channels like HF-radios. It is used in tandem with s4406. The Military Messaging System converts messages from s4406 to DMP.
