5、ns working towards the further development and improvement of voluntary standardization in the national interest. The principal objects of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety, and welfare of the p
6、ublic, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which reilects a reasonable
7、agreement among the views of a number of capable individuals whose collective interests provide to the greatest practicable extent a balance of representation of producers, users, consumers, and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard w
8、hich is capable of making a significant and timely contribution to the national interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria and procedures established by the Slandards Council of Canada. Approval does not refer to the technical
9、 content of the standard; this remains the continuing responsibility of the accredited standards-development organization. Those who have a need to apply standards are encouraged to use National Standards of Canada whenever practicable. These standards are subject to periodic review; therefore, user
10、s are cautioned to obtain the latest edition from the organization preparing the standard.

Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory C
15、ommittee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the IS0 member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Ca
16、nada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). This Standard coexists with CAN/CSA-Z243.165-89 (adoption of IS0 8823:1988). This International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Informati
17、on Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Committee Administrator.) From time to time, 1SO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication. For a listing, re
18、fer to the CSA Information Products Catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by these Committees and has been approved as a National Standard of Canada by the Standards Council of Canada. February 7997 0 Canad

It is expected that the initial users of this ITU-T Recommendation I International Standard will be designers and implementors of equipment and therefore it contains, in notes or in annexes, guidance on the implement
28、ation of its procedures. It has not been possible as yet to prepare a product standard containing a set of objective tests for conformance to this ITU-T Recommendation I International Standard, but it does contain a section on conformance of equipment claiming to implement the procedures it specifie
29、s. Attention is drawn to the fact that this ITU-T Recommendation I International Standard does not contain any tests to demonstrate this conformance and cannot, therefore, be considered as a complete product standard. The variations and options available within this ITU-T Recommendation I Internatio
30、nal Standard are essential to enable a presentation-service to be provided for a wide variety of applications. Thus, a minimally conforming implementation will not be suitable for use in all possible circumstances. It is necessary, therefore, to qualify all references to this ITU-T Recommendation I
31、International Standard with statements of the options provided or required, or with statements of the intended purpose of provision or use.
