CAN/CSA-Z243.179-91 (R2000)

Scope

This International Standard is to be applied by reference from other specifications. This is done within such specifications by reference to the CCR services defined in ISO/IEC 9804. A reference to a CCR service invokes the procedures of this International Standard to cause external effects.

This International Standard applies whenever the use of CCR services does not encompass any communication activity which makes direct or indirect use of the session activity management services defined in ISO 8326. It can be used inside a session activity, and on a session-connection where the session activity functional unit is not in use. It can also be applied when the S-ACTIVITY service is used through the mechanisms of annex B.

This International Standard specifies the static and dynamic conformance requirements for systems implementing these procedures. It does not contain tests which can be used to demonst rate conformance.
