2 AMHS Addressing MHS OR-Address (Mnemonic Form) AMHS MF-Address Common semantics for the high level attributes C, A and P for international routing Common AMHS Addressing Scheme (CAAS) SARPs defined MF-Addressing Schemes XF-Addressing Scheme Locally Defined Addressing Schemes Definition of low level attributes for routing within an PRMD ATS Message Handling System (AMHS) Part 1-2

3 AMHS Addressing Scenario with CAAS Originator uses AFTN (AF) address of recipient Gateway converts AF! CAAS address AFTN (1) x 4 AMHS 2 AFTN (2) x x AFTN users are identified by AFTN (AF) and CAAS addresses Gateway converts CAAS! AF address AFTN/AMHS Gateway 3 1 x CAAS Originator uses CAAS address of recipient Originator Originator uses AFTN (AF) address of recipient AFTN (3) Gateway converts AF! CAAS address x Recipient Message Flow ATS Message Handling System (AMHS) Part 1-2
