Source ITU-T Recommendation X.483 was revised by ITU-T Study Group 7 (1997-2000) and was approved under the
9、WTSC Resolution No. 1 procedure on the 25th of September 1998. As a result of Study Group 7 decision to publish a consolidated new edition of the set of Message Handling Recommen- dations, it was decided that, in agreement with the TSB Director, X.481, X.482, X.483, X.484 and X.486 will also be publ
10、ished with 1999 dates. Recommendation X.483 (06/99) 1 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommuni- cations. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible
11、 for studying technical, operating and tariff questions and issuing Recommendations 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
12、 Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards a
13、re prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation the term recognized operating agency (ROA) includes any individual, company, corporation or governmental organization that operates a public correspondence service. The terms Administration, ROA and public corresponde
14、nce are defined in the Constitution of the ITU (Geneva, 1992). INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evi
15、dence, 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, the ITU had not received notice of intellectual property, protected by patents, wh
16、ich 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. O ITU 2000 All rights reserved.

19、 Page 1 1 1 1 1 2 2 3 39 . 111 STD-ITU-T RECMN X.483-ENCL Introduction This Recommendation is one in a set of Recommendations defining Message Handling in a distributed open system environmen t. Message Handling provides for the exchange of messages between users on a store-and-forward basis. A mess
20、age submitted by one user (the originator) is transferred through the Message Transfer System (MTS) and delivered to one or more users (the recipients). The MTS comprises a number of Message Transfer Agents (MTAs), which transfer messages and deliver them to their recipients. To evaluate the capabil
21、ities of a particular implementation, it is necessary to have a statement of which capabilities and options have been implemented for a given OS1 protocol. Such statement is called a Protocol Implementation Conformance Statement (PICS). iv Recommendation X.483 (06/99) - Recommendation X.483 MESSAGE
22、HANDLING SYSTEMS - P3 PROTOCOL PICS PROFORMA 1 Scope This Recommendation provides the Protocol Implementation Conformance Statement (PICS) proforma for the P3 protocol specified in ITU-T Rec. X.411 I ISOIEC 10021-4 and ITU-T Rec. X.419 I ISOAEC 10021-6. The PICS proforma presents in tabular form the
23、 mandatory and optional elements of the P3 protocol. This PICS proforma is based on the relevant guidance for PICS proformas given in ITU-T Rec. X.296 I ISOIEC 9646-7. 2 Normative references The following ITU-T Recommendations, and other references contain provisions which, through reference in this
24、 text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; all users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent e

41、mendation may freely reproduce the PICS proforma in this annex so that it can be used for its intended purpose and may further publish the completed PICS. Recommendation X.483 (06/99) 3 STDoITU-T RECMN Xa483-ENGL 1999 4862573 0667228 028 The proforma is in the form of a questionnaire and consists of
42、 a set of items. An item is provided for each capability for which no implementation choice is allowed. Items are also provided for mandatory capabilities for which no implementation choice is allowed. Each item includes an item number, an item description, a status value specifying the support requ
43、irement, and room for a support answer to be provided by the supplier. A.0.1.2 Item numbering Each line in the PICS proforma which requires implementation detail to be entered is given a number in the first column. The item number column provides a means of uniquely referencing each possible answer
44、within the PICS proforma. A.0.1.3 Base column In each table, the “Base“ column reflects the level of support required for conformance to the base standard. The generic term “MTS-user“ is used in the tables where the distinction between different types of MTS-user is not significant. Where a column i
45、s headed “UA“, then an MS is only required to be able to pass through such elements transparently between a UA and the MTA. The following classifications are used in this PICS to specify static conformance requirements - i.e. capability. NOTE - The Profile column is used for functional profiles and
46、uses the same classification. In the case of protocol elements, the classification is relative to that of the containing element, if any. Where the constituent elements of a non-primitive element are not individually specified, then each shall be considered to have the classification of that element
47、. Where the range of values to be supported for an element is not specified, then all values defined in the MHS base standards shall be supported. mandatory support (m): The element or feature shall be fully supported. An implementation shall be able to generate the element, andor receive the elemen
48、t and perform ail associated procedures (i.e. implying the ability to handle both the syntax and the semantics of the element) as relevant, as specified in the MHS base standards. Where support for origination (generation) and reception are not distinguished, then both Capabilities shall be assumed.
49、 optional support (o): An implementation is not required to support the element or feature. If support is claimed, the element shall be treated as if it were specified as mandatory support. If support for origination is not claimed, then the element is not generated and, in the case of non-support of a critical extension by an MTA implementation on delivery, shall cause a non-delivery notification to be returned. If support for reception is not claimed, and the element is an argument, then an implementation may ignore a non-critical extension on delivery but sha
