适用范围：This Recommendation is one of a series of Recommendations and describes the access protocol for Teletex Terminals to the Message Handling System (MHS). This Recommendation specifies the protocol to be used by Teletex (TTX) terminals when accessing the MHS for the purpose of providing the Interpersonal Messaging (IPM) Service to their users. The IPM service elements are made available to users of the Teletex Service.Other Recommendations in the series contain additional information essential to a thorough understanding of the MHS. Recommendation X.401 outlines the basic service elements and optional user facilities of the IPM and Message Transfer (MT) Services. Recommendation X.400 describes the MHS model and defines the IPM and MT service elements. 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 the MHS uses when converting between different types of encoded information. Recommendation X.410 describes general techniques used for MHS protocols and the way in which standard Open Systems Interconnection (OSI) protocols are used to support MHS applications.§ 2 of this Recommendation defines the Teletex Access Model, the actions of the protocol used by the Teletex terminal, and the operation of the Teletex Access Unit (TTXA U). § 3 describes the various action elements used. § 4 provides details on the control procedures defined. § 5 defines the error recovery procedures. § 6 describes the encoding and formatting of control information. § 7 lists the appropriate references.
