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.
