The context of the NTCIP is one part of
44、 the Intelligent Transportation Systems standardization activities covering base standards, profiles, and registration mechanisms. Base Standards define procedures and rules for providing the fundamental operations associated with communications and information that is exchanged over fixed-point com
45、munications links. Profiles define subsets or combinations of base standards used to provide specific functions or services. Profiles prescribe particular subsets or options available in base standards necessary for accomplishing a particular function or service. This provides a basis for the develo
46、pment of uniform, nationally recognized conformance. Registration Mechanisms provide a means to specify and uniquely identify detailed parameters within the framework of base standards and/or profiles. This publication provides the definition of an NTCIP Subnetwork Profile. It defines requirements f
47、or the data link and physical layers of a communications stack based upon the OSI Basic Reference Model. It also contains optional and conditional clauses that are applicable to specific environments for which they are intended. This document is an NTCIP Subnetwork Profile document. Subnetwork Profi
48、le documents define the requirements of the data link and physical layers of a communications stack based upon the OSI Basic Reference Model.
