Annex A (informative) A-deviations

This European Standard specifies DSRC profiles which provide coherent sets of communication tools for applications based on DSRC. These sets consist of subsets of functionality described in prEN 12253, EN 12795 and EN 12834, out of which a minimum subset is mandatory.The DSRC Standards prEN 12253, EN 12795 and EN 12834, which together form a three-layered architecture for DSRC, are designed to encompass a wide range of services for different purposes in order to make the basic DSRC architecture suited for many different applications and for a wide range of possible products and systems.DSRC systems can be built using one-way (downlink) or two-way (interactive) communication. The DSRC profiles described in this European Standard are intended for interactive DSRC systems based on two-way communication and DSRC systems using one-way communication (broadcast services).While prEN 12253 contains very little variation, EN 12795 and especially EN 12834 describe a wide range of communication services. It has not been considered feasible to assume that any one piece of equipment is designed to implement all of these services. It is often the case that the functionality of the on board unit is more limited than the functionality of the roadside unit.This European Standard covers-Physical Layer parameter values-Data Link Layer subsets-Application Layer subsets-Initialisation procedures-Late response procedures-Termination procedures
