CSA Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This International Standard specifies service description and control aspects of the broadband connection oriented bearer services which may be provided by Broadband Private Integrated Services Networks (B-PISNs). One of the purposes of the service specification for broadband connection oriented bearer services is to guide and constrain the work on signalling protocols. Therefore, this International Standard is concerned mainly with the control aspects of services. Change of traffic characteristics during a call is outside the scope of this International Standard. Charging considerations are outside the scope of this International Standard.
