9、participate in ITU-T which is the body which sets world telecommunications standards (Recommendations). The approval of Recommendations by the Members of IT-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, 1993). In addition, the World Telecommunication Standardization Con

10、ference (WTSC), which meets every four years, approves Recommendations submitted to it and establishes the study programme for the following period. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IE

17、 service element protocol (see ITU-T Rec. X.852 1 ISOAEC 9805-1). The PICS present, in a tabular form, the mandatory and optional elements of the ACSE protocol. The PICS are utilized to represent the choices and features of a particular implementation of OS1 ACSE. Introduction This Recommendation I

18、International Standard is one of a set of Recommendations I International Standards produced to facilitate the interconnection of information processing systems. It is related to other Recommendations and International Standards in the set as defined by the Reference Model for Open Systems Interconn

19、ection (see ITU-T Rec. X.200 I ISO/IEC 7498-1). The Reference Model subdivides the area of standardization for interconnection into a series of layers of specification, each of manageable size. The goal of Open Systems Interconnection is to allow, with a mimum of technical agreement outside the inte

20、rconnection standards, the interconnection of infomation processing systems: - fiom different manufacturers; - under different managements; - - of different technologies. of different levels of complexity; and ITU-T Rec. X.227 I ISOAEC 8650-1 specifies the connection-oriented mode protocol for the a

21、pplication-service-element for application-association control:.the Association Control Service Element (ACSE). The ACSE connection-oriented mode provides services for establishing and releasing application-associations. The ACSE protocol also includes an optional functional unit for exchanging info

22、rmation to support authentication during association establishment. The ACSE services apply to a wide range of application-proccess communication requirements. To evaluate the conformance of a particular implementation, it is necessary to have a description of the capabilities and options which have

23、 been implemented. Such a description is called a Protocol Implementation Conformance Statement (PICS). This Recommendation I International Standard includes the PICS proforma for the connection-oriented ACSE protocol as defined in ITU-T Rec. X.227 I ISOAEC 8650-1. . ITU-T Rec. X.247 (1996 E) 111 ST

Identification of PICS proforma corrigenda I I con: A.2 Instructions A.2.1 The purpose of this PICS proforma is to provide suppliers of implementations of IT-T Rec. X.227 I ISOAEC 8650-1 with a consiste

45、nt means of stating which capabilities have 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 major mandatory capabilities for which no im

46、plementation choice is allowed. Each item includes an item number, an item description, a status value speciQing the support requirement, and room for a support answer to be provided by the supplier. This subclause provides general information and instructions for completion of the proforma. Subclau

47、se A.3 is for identification of the implementation. Subclause A.4 contains the means of speciaing, at a high level, the protocol and comgenda that have been implemented. Subclause A.5 contains the global statement of conformance. Subclause A.6 onwards contain tables in which the supplier specifies d

48、etails of the implementation options chosen. A.2.2 Symbols, terms and abbreviations Purpose and structure of the proforma A.2.2.1 Introduction Notations have been introduced in order to reduce the size of tables in the PICS proforma. These have allowed the use of multi-column layout where the column

49、s are headed Status, and Support. The definition of each are given below. Additionally, the following definitions apply: A.2.2.1.1 (PICS) item: A row in a PICS proforma table. A.2.2.1.2 (PICS) question: The question to be answered in the intersection of a PICS item and either a support column (Le. “Is this item supported in the context applying to this table and column”) or supported values column (i.e. “What values are supported for this item in the context applying to this table and column”) in a PICS proforma table.
