8、Agency in the field of telecommunications. The I” Telecommunication Standardization Sector (ITU-T) is a permanent organ of the . Some 179 member countries, 84 telecom operating entities, 145 scientific and industrial organizations and 38 international organizations participate in ITU-T which is the

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

10、 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 IEC. The text of ITU-T Recommendati

11、on X.246 was approved on 5th of October 1996. The identical text is also published as ISO/IEC International Standard 8823-2.

16、ation I International Standard describes the protocol implementation conformance statement for the OS1 connection-mode presentation protocol (see ITU-T Rec. X.226 I ISOAEC 8823-1). The PICS presents, in tabular form, the mandatory and optional elements of the TP protocol. The PICS is utilized to rep

17、resent the choices and features of a particular implementation of the OS1 presentation protocol. Introduction This Recommendation I International Standard is one of a set of Recommendations I International Standards produced to facilitate the interconnection of information processing systems. It is

18、related to other Recommendations and International Standards in the set as defined by the Reference Model for Open Systems Interconnection (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,

19、 each of manageable size. The goal of Open Systems Interconnection is to allow, with a mimurn of technical agreement outside the interconnection standards, the interconnection of information processing systems: - fiom different manufacturers; - under different managements; - - of different technolog

20、ies. of different levels of complexity; and ITU-T Rec. X.226 1 ISOAEC 8823-1 specifies the connection-oriented presentation protocol. It specifies a common encoding and a number of functional units of presentation protocol procedures to be used to meet the needs of presentation-service-users. To eva

21、luate the conformance of a particular implementation, it is necessary to have a description of the capabilities and options which have been implemented. Such a description is called a Protocol Implementation Conformance Statement This Recommendation 1 Intemational Standard includes the PICS proforma

22、 for the connection-oriented presentation protocol as defined in ITU-T Rec. X.226 I ISOAEC 8823-1. (PICS). ITU-T Rec.

43、 purpose of this PICS proforma is to provide suppliers of implementations of ITU-T Rec. X.226 I ISOAEC 8823-1 with a consistent 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 capab

44、ility for which an implementation choice is allowed. Items are also provided for major mandatory capabilities for which no implementation 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 p

45、rovided by the supplier. This subclause provides general information and instructions for completion of the proforma. Subclause A.3 is for identification of the implementation. Subclause A.4 contains the means of speciSling, at a high level, the protocol and corrigenda that have been implemented. Su

46、bclause AS contains the global statement of conformance. Subclause A.6 onwards contain tables in which the supplier specifies details of the implementation options chosen. A.2.2 Symbols, terms and abbreviations A.2.2.1 Introduction Notations have been introduced in order to reduce the size of tables

47、 in the PICS proforma. These have allowed the use of multi-column layout where the columns are headed Status, and Support. The definition of each is 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 quest

48、ion 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 pro
