8、s Protocol, as defined in ITU-T Rec. X.413 I ISOAEC 10021-5 and ITU-T Rec. X.419 I ISOLIEC 10021-6. Source ITU-T Recommendation X.487 was prepared by ITU-T Study Group 7 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 18th of June 1999. FOREWORD ITU (International Telec
9、ommunication 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 for studying technical, operating and tariff questions and issuing Recommendations on
10、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 their turn, produce Recommendations on these topics. The approv
11、al 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 are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation the
12、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 correspondence are defined in the Constitution of the ITU (Geneva, 1992). INTELLECTUAL PROPERTY RI
13、GHTS 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 evidence, validity or applicability of claimed Intellectual Property Rights, whether asser
14、ted 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, which may be required to implement this Recommendation. However, impiementors are caution
15、ed that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. O ITU 1999 All rights reserved.

18、GL- 1999 = 44b2573 0bb4543 305 lsl 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 store-and-forward basis. A message submitted by one use
19、r (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 capabilities of a particular im
20、plementation, it is necessary to have a statement of which capabilities and options have been implemented for a given OS1 protocol. Such a statement is called a Protocol Implementation Conformance Statement (PICS). iv Recommendation X.487 (06/99) I I Recommendation X.487 MESSAGE HANDLING SYSTEMS - I
21、PM-MS ATTRIBUTES PICS PROFORMA (Geneva, 1999) 1 Scope This Recommendation provides the Protocol Implementation Conformance Statement (PICS) proforma for the IPM-MS attributes specified in ITU-T Rec. X.413 I ISO/IEC 10021-5 and ITU-T Rec. X.419 I ISO/IEC 10021-6. The PICS proforma presents in tabular
22、 form the mandatory and optional IPM-MS attributes. This PICS proforma is based on the relevant guidance for PICS proformas given in ITU-T Rec. X.296 I ISOAEC 9646-7. 2 Normative references The following Recommendations and International Standards contain provisions which, through reference in this
23、text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and Standards are subject to revision, and parties to agreements based on this Recommendation are encouraged to investigate the possibility of applying the most rece
24、nt edition of the Recommendations and Standards listed below. Members of IEC and IS0 maintain registers of currently valid International Standards.

38、f the PICS proforma is to provide suppliers of implementations of the P7 protocol with a consistent means of 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
39、 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 requirement, and room for a support answer to be provided by the supplier. I A.0.1.2 Ite
40、m 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 within the PICS proforma. A.0.1.3 Base column In each table, the “Base“ column r
41、eflects the level of support required for conformance to the base standard. 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 uses the same classification. In the case of pro
42、tocol 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. Where the range of values to be supported for
43、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, and/or receive the element and perform all associated procedures (i.e. i
44、mplying 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. Mandatory support of an MS attribute for the M
45、S requires that it is supported in the context of all applicable supported operation arguments and results. Mandatory support of an MS attribute by the MS-user requires that it is supported in the context of at least one supported operation argument and result. The way in which attribute values are
46、stored by an MS implementation, or used by a UA implementation, is otherwise a local matter. 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 is not
47、claimed, and the element is an argument, then an implementation shall generate an appropriate error indication if the element is received. If support is not claimed, and the element is a result, then an implementation may ignore the element if it is received. If support of an operation as a responde
48、r is not claimed, then an appropriate error indication shall be generated (as a minimum, a ROSE reject shall be generated). 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 i
49、t were specified as mandatory support. If these conditions are not met, the element shall be treated as if it were specified as optional support (unless otherwise stated). out of scope (i): The element is outside the scope of this Recommendation - i.e. it will not be the subject of a conformance test. not applicable (-): The element is not applicable in the particular context in which this classification is used.
