This Recommendation is one of a series of Recommendations and describes the system model and service elements of the message handling system (MHS). This Recommendation defines the message handling (MH) services that Administrations provide to enable subscribers to exchange messages on a store-and-forward basis. Two MH services are provided. The interpersonal messaging (IPM) service supports interpersonal communication, including communication with existing CCITT Telex and Telematic services. The message transfer (MT) service supports general, application-independent message transfer. Other Recommendations in the series contain additional information essential to a thorough understanding of the MHS. Recommendation X.401 lists the basic service elements and optional user facilities. Recommendation X.411 specifies the protocol aspects of the MT service. Recommendation X.420 specifies the protocol aspects of the IPM service. Recommendation X.409 defines the notation and representational technique used to specify and encode MHS protocols. Recommendation X.408 specifies the algorithms that the MHS uses when converting between different types of encoded information. Recommendation X.430 describes how Teletex terminals access the MHS. Recommendation X.410 describes the general techniques used for MHS protocols and the way in which standard Open Systems Interconnection (OSI) protocols are used to support MHS applications. The MH services and provided by means of the Message Handling System (MHS). § 2 of this Recommendation introduces a functional model of message handling systems and its applicability to a variety of physical and organizational configurations. § 3 describes the system's provisions for naming and addressing. § 4 describes the MH Service elements in detail. § 5 presents a layered model of the MHS, using the Reference Model of Open Systems Interconnection for CCITT Applications (Recommendation X.200) hereafter called the OSI Reference Model.
