Test environment

The AMHS Test Suite uses a test configuration as shown in the figure below to verify the IUT's submission, transfer and delivery operation and to perform AFTN/AMHS gateway tests in both directions. It implements

  • three MTA instances representing three adjacent ATS Message Servers or three neighboring domains (PRMDs), and
  • one AFTN source/sink representing an adjacent AFTN environment with three countries.

The AMHS test tool will be interconnected with the IUT's standardized external interfaces, which are:

  • three AMHS transfer ports supporting the X.400/P1 protocol over a TCP/IP/LAN, and
  • one AFTN test interface supporting either asynchronous comunication over serial line, the CIDIN/X.25 protocols or the TCP/IP protocols for AFTN message exchanges.

AMHS over ATN protocols can be configured as an option.

The AMHS Test Suite makes use of the standardized test addressing plan, which is specified in the EUR AMHS Manual, Appendix D for AMHS conformance testing.

Test addresses are defined for three generic AMHS PRMDs called AMHSLAND-1, AMHSLAND-2, AMHSLAND-3 and and three generic AFTN countries called AFTNLAND-1, AFTNLAND-2 and AFTNLAND-3. This allows covering of all recognized addressing schemes including

  • CAAS, the Common AMHS Addressing Scheme, with either a single organization-name value, or
  • CAAS with multiple organization-name values for different sets of location identifiers, or
  • XF, the translated-form addressing scheme.
