ISO International Standard

This Recommendation | International Standard specifies:

a) procedures for the transfer of information among application-service-objects (ASOs); and

b) the abstract and concrete syntax for the representation of the A-UNIT-DATA ACSE APDU.

The A-UNIT-DATA procedure is defined in terms of:

a) The interactions between peer ACSE protocol machines by the use of a supporting service; and

b) the interaction between an ACSE protocol machine, its service-provider and its service-user.

These procedures are applicable to instances of communication between systems which wish to communicate in an open

systems interconnection environment in a connectionless mode.

This Recommendation | International Standard also specifies conformance requirements for systems implementing this

procedure. It does not contain tests which can be used to demonstrate conformance.
