ISO 18445:2016

ISO 18445:2016 Practice defines extensions to the SLE API in terms of: a) the CLTU-specific functionality provided by API components; b) the CLTU-specific interfaces provided by API components; and c) the externally visible behavior associated with the CLTU interfaces exported by the components. It does not specify a) individual implementations or products; b) the internal design of the components; and c) the technology used for communications. ISO 18445:2016 defines only interfaces and behavior that must be provided by implementations supporting the forward CLTU service in addition to the specification in reference [5].
