ITU-T RECOMMENDATION X.481 MESSAGE HANDLING SYSTEMS - P2 PROTOCOL PICS PROFORMA Summary This Recommendation provides the Protocol Implementation Conformance Statement (PICS) proforma for the Message Handling Systems (MHS) 2 protocol specified in ITU-T Rec. X.420 I ISOAEC 10021-7. The P

8、ICS proforma presents in tabular form the mandatory and optional elements of the P2 protocol. Source ITU-T Recommendation X.481 was revised by ITU-T Study Group 7 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 25th of September 1998. As a result of Study Group 7 decisi

9、on 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 published with 1999 dates. I Recommendation X.481 (06/99) 1 FOREWORD ITU (International Telecommunicat

10、ion Union) is the United Nations Specialized Agency in the field of telecommuni- cations. The ITU Telecommunication Standardization Sector (IT-T) is a permanent organ of the ITU. The IT-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a

11、 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 their turn, produce Recommendations on these topics. The approval of Recom

12、mendations 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 IT-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation the term recogni

13、zed operatirlg agency (ROA) includes any individual, company, corporation or governmental organization that operates a public correspondence service. The terms Administration, ROA and public correspondence are defined in the Constitution of the ITU (Geneva, 1992). INTELLECTUAL PROPERTY RIGHTS The IT

14、 draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The IT takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU me

15、mbers 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, which may be required to implement this Recommendation. However, implementors are cautioned that this

16、may not represent the latest information and are therefore strongly urged to consult the TSB patent database. o ITU 2000 All rights reserved.

Recommendation X.481 (06199) 111 Introduction This Recommendation is one in a set of Recommendations defining Message Handling in a distributed open system environment. Message Handling provides for the exchange of messages between users on a stor

20、e-and-forward basis. A message submitted by one user (the originator) is transferred through the Message Transfer System (MTS) and delivered to one or more users (the recipients). The users access is through a User Agent (UA). To evaluate the capabilities of a particular implementation, it is necess

21、ary 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.481 (06/99) .- STD-ITU-T RECMN X-481-ENGL 1999 = 48b2593i Obbb2b7 980 m Recommendation X.

22、481 MESSAGE HANDLING SYSTEMS - P2 PROTOCOL PICS PROFORMA 1 Scope This Recommendation provides the Protocol Implementation Conformance Statement (PICS) proforma for the P2 protocol specified in ITU-T Rec.

X.296 I ISO/IEC 9646-7. 2 Normative references The following ITU-T Recommendations and International Standards contain provisions which, through reference in this text, constitute p

24、rovisions of this Recommendation I International Standard. At the time of publicacion, the editions indicated were valid. All Recommendations and Standards are subject to revision, and parties to agreements based on this Recommendation I International Standard are encouraged to investigate the possi

25、bility of applying the most recent edition of the Recommendations and Standards listed below. Members of IEC and IS0 maintain registers of currently valid International Standards. The Telecommunication Standardization Bureau of the ITU maintains a list of currently valid ITU-T Recommendations. I 2.1

Subclause A.2 is allocated but not used; it is present to keep the numbering alignment with the corresponding ISP. Subclause A.3 allows additional information to be provided for certain aspects of an

38、implementation where no specific requirements are included in the base specifications. All subclauses shall be completed as appropriate. NOTE -The numbering of subclauses and items in this annex is identical to that in ISOIIEC ISP 12062-2, “Information technology - International Standardized Profile

A.0 Instructions and identification A.O.l Instructions A.O.l.1 Purpose of the proforma The purpose of the PICS proforma is to provide suppliers of implementations of the P2 protocol with a consistent means o

40、f stating which proforma has been implemented. The proforma is in the form of a questionnaire and consists of a set of items. An item is provided for each capability for which an implementation choice is allowed. Items are also provided for mandatory capabilities for which no implementation choice i

41、s allowed. Each item includes an item number, an item description, a status value specifying the support requirement, and room for a support answer to be provided by the supplier. * Copyright release for PICS proformas Users of this Recommendation may freely reproduce the PICS proforma in this annex

Recommendation X.481 (06199) 3 STD-ITU-T RECMN XmYBL-ENGL 1999 48b259L 0666270 ri75 D A.0.1.2 Item numbering Each line in the PICS proforma which requires implementation detail to be entered is given a numb

43、er in the first column. The item number column provides a means of uniquely referencing each possible answer 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 following classifications are u

44、sed in this PICS to specify static conformance requirements - i.e. capability. NOTE 1 - The Profile column is used for functional profiles and uses the same classification. The classification of information objects and items (elements) is relative to that of the containing information element, if an

45、y. 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. 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

46、 supported. mandatory support (m): The element shall be supported. An implementation shall be able to generate the element, andor receive the element and perform all associated procedures (Le. implying the ability to handle both the syntax and the semantics of the element) as relevant, as specified

47、in the MHS base standards. Where support for origination (generation) and reception are not distinguished, then both capabilities shall be assumed. NOTE 2 - In the case of character repertoires, mandatory support implies that the IPM UA implementation is able to generate and/or receive the encodings

48、 of all characters within those repertoires. How graphic characters are originated and rendered is outside the scope of this Recommendation. NOTE 3 - Where required by the base standards, mandatory support also implies that the IPM UA implementation is able to pass the element on the origination por

49、/reception port to/from the corresponding element on the submission poddelivery podretrieval port. optional support (o): An implementation is not required to support the element. If support is claimed, then the element shall be treated as if it were specified as mandatory support. If the element is not supported on reception, then it shall be ignored. conditional support (c): The element shall be supported under the conditions specified in this Recommendation. If these conditions are met, the element shall be treated as if it were specified as mandatory support
