CAN/CSA-Z243.171-89 (R2000)

This National Standard of Canada is equivalent to International Standard ISO 8650-1988. 1 Scope and Field of Application The procedures defined in this International Standard are applicable to instances of communication between systems which wish to interconnect in an open systems interconnection environment. This International Standard specifies: (a) procedures for the transfer of information relating to application-association control between application-entities; and (b) the abstract syntax for the representation of the ACSE APDUs. The ACSE procedures are defined in terms of: (a) the interactions between peer ACSE protocol machines through the use of presentation-services; and (b) the interaction between an ACSE protocol machine and its service-user. This International Standard also specifies conformance requirements for systems implementing these procedures. It does not contain tests which can be used to demonstrate conformance.
