CAN/CSA-ISO/IEC 10021-6:04 (R2014)

This National Standard of Canada is equivalent to International Standard ISO/IEC 10021-6:2003. 1 Scope This Recommendation | International Standard specifies the MTS Access Protocol (P3) used between a remote user-agent and the MTS to provide access to the MTS Abstract Service defined in ITU-T Rec. X.411 | ISO/IEC 10021-4. This Recommendation | International Standard also specifies the MS Access Protocol (P7) used between a remote user-agent and a message-store (MS) to provide access to the MS Abstract Service defined in ITU-T Rec. X.413 | ISO/IEC 10021-5. This Recommendation | International Standard also specifies the MTS Transfer Protocol (P1) used between MTAs to provide the distributed operation of the MTS as defined in ITU-T Rec. X.411 | ISO/IEC 10021-4. ITU-T Rec. X.402 | ISO/IEC 10021-2 identifies the other Recommendations | International Standards which define other aspects of Message Handling Systems. Section two of this Recommendation | International Standard specifies the MHS Access Protocols (P3 and P7). Clause 6 provides an overview of the MHS Access Protocols. Clause 7 defines the abstract-syntax of the MTS Access Protocol (P3). Clause 8 defines the abstract-syntax of the MS Access Protocol (P7). Clause 9 defines the mapping of the MHS Access Protocols onto used services. Clause 10 specifies conformance requirements for systems implementing the MHS Access Protocols. Section three of this Recommendation | International Standard specifies the MTS Transfer Protocol (P1). Clause 11 provides an overview of the MTS Transfer Protocol (P1). Clause 12 defines the abstract-syntax of the MTS Transfer Protocol (P1). Clause 13 defines the mapping of the MTS Transfer Protocol (P1) onto used services. Clause 14 specifies conformance requirements for systems implementing the MTS Transfer Protocol (P1). Annex A provides a reference definition of the MHS protocol object identifiers cited in the ASN.1 modules in the body of this Recommendation | International Standard. Annex B describes protocol rules for interworking with implementations of the CCITT Recommendation X.411 (1984) using the MTS Transfer Protocol (P1). Annex C identifies the differences between the CCITT Recommendation X.411 (1984) and this Recommendation | International Standard. Annex D identifies the technical differences between the ISO/IEC and ITU-T versions of ITU-T Rec. X.419 and ISO/IEC 10021-6. Annex E covers use of lower layer services, and is only applicable to ITU-T Recommendation X.419. Annex F provides an index to this Recommendation | International Standard, categorised into: Abbreviations; Terms; Information Items; ASN.1 modules; ASN.1 information object classes; ASN.1 types; and ASN.1 values.
