scope:
Covers the services required of, or by, the data communication protocol (DCP) logical link control (LLC) sublayer entity at the logical interfaces with the LLC-user layer and the MAC sublayer, using the connection-oriented LLC procedures. Services are specified showing the information flow between the LLC user and the MAC service, by describing the service primitives and parameters which characterize each service: these service primitives are those specified in IEC 61334-4-32 and in this standard, only the specific details and changes for connection-oriented procedures are given. The primitives in this standard are associated with connection-oriented mode (CO) LLC protocol, providing connectionless services: a data transfer mode outside the connection context is provided and harmonized with the CO procedures.
