scope:

This part of MIL-STD 2045-17502 covers the interchange of messages between Military Messaging (MM) User Agents (UAs) (see also figure 1). These specifications form part of the Military Messaging application functions, as defined in the parts of MIL-STD 2045-17502, and are based on the Common DoD Messaging content type-independent specification in MIL-STD 2045-17501.

This part of MIL-STD 2045-17502 is the second part of a multipart DSP identified as AMH2n(D) Message Handling Systems - Military Messaging.

This part of MIL-STD 2045-17502 specifies the following profile:

AMH21(D) - MM Content

The AMH21(D) profile may optionally be combined with profile AMH23(D) or profile AMH24(D) specifying OSI MHS communications protocols and supporting services for an MM UA.

The model used is one of indirect interchange of military messages (content type P772) between MM UAs via an intermediate Message Transfer System (MTS), as shown in figure 1. The provision of, and access to, the MTS is outside the scope of this profile.

The MHS services and functions covered by the AMH21(D) profile are specified in ACP 123. There are no OSI upper layer services and protocols within the scope of the AMH21(D) profile.
