Note. According to conformance rules in ISO 8327:
•
At least one of the functional units Duplex and Half Duplex shall be implemented.
•
If the Capability Data Exchange functional unit is implemented, the Activity Management
functional unit shall also be implemented.
•
If the Exceptions functional unit is implemented, the Half-Duplex functional unit shall also
be implemented.
