This part of ISO/IEC 15802 defines the Medium Access Control Service found in local area network architecture in abstract terms of
(a) the primitive actions and events of the service;
(b) the parameters associated with each primitive action and event, and the form they take; and
(c) the interrelationship between, and the valid sequences of, these actions and events.
The principal objectives of this part of ISO/IEC 15802 are
(a) to specify the characteristics of a conceptual Medium Access Control Service;
(b) guide the development of Medium Access Control Protocols; and
(c) guide the development of OSI protocols which make use of the MAC Service.
This part of ISO/IEC 15802 does not specify individual implementation or products, nor does it constrain the implementation of Medium Access Control entities and interfaces within an information processing system.
There is no conformance of equipment to this part of ISO/IEC 15802. Instead, conformance is achieved through implementation of conforming Medium Access Control Protocols that fulfill the Medium Access Control Service defined in this part of ISO/IEC 15802.
