8、ns of P3 and P7 introduced in Recommendations X.411 and X.413. The P1 conformance requirement has been revised to achieve common text with ISO/IEC. The ASN.1 has been fully revised to use the new Recommendations X.680 and X.880, while retaining complete compatibility with the 1988 and 1992 P1 and P3
9、 protocols. This Recommendation | International Standard incorporates an enhancement on use of ISO/IEC 10646 characters in OR-addresses and numerous defect corrections. Source The ITU-T Recommendation X.419 was approved on 18 June 1999. The identical text is also published as ISO/IEC International S
10、tandard 10021-6. Following ITU-T decision to publish new editions of the set of Message Handling Recommendations, this edition of ITU-T Rec. X.419 (11/1995), X.419 Technical Corrigendum 1 (08/1997), X.419 Amendment 1 (12/1997) and X.419 Amendment 2 (09/1998). ii ITU-T Rec. X.419 (06/1999) FOREWORD T
11、he International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Re
12、commendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
13、 The approval of ITU-T Recommendations is covered by the procedure laid down in WTSC Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Ad
14、ministration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Pr
15、operty Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had/had not received not
16、ice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2003 All rights reserved. No par

31、his Protocol Specification is one of a set of Recommendations | International Standards defining Message Handling in a distributed open systems environment. Message Handling provides for the exchange of messages between users on a store-and-forward basis. A message submitted by one user (the origina
32、tor) is transferred through the Message Transfer System (MTS) and delivered to one or more other users (the recipients). A user may interact directly with the MTS, or indirectly via a Message Store (MS). The MTS comprises a number of message-transfer-agents (MTAs), which transfer messages and delive
33、r them to their intended recipients. This Protocol Specification was developed jointly by ITU-T and ISO/IEC. It is published as common text as ITU-T Rec. X.419 | ISO/IEC 10021-6. ISO/IEC 10021-6:2003 (E) ITU-T Rec. X.419 (06/1999) 1 INTERNATIONAL STANDARD ITU-T RECOMMENDATION Information technology

36、cifies 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 S
37、ystems. 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 P
38、rotocol (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
39、 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

Annex B describes protocol rules for interworking with implementations of the CCITT Recommendation X.411 (1984) using
41、 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 cov
42、ers 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.
