This document specifies the data transfer models between roadside equipment (RSE) and integrated circuit cards (ICCs) and the interface descriptions between the RSE and on-board equipment (OBE) for on-board accounts using an ICC. It also provides examples of interface definitions and transactions deployed in several countries.

This document covers:

—   

data transfer models between the RSE and ICC which correspond to the categorized operational requirements and the data transfer mechanism for each model;

—   

the interface definition between the RSE and OBE based on each data transfer model;

—   

the interface definition for each model;

—   

the functional configuration;

—   

RSE command definitions for ICC access;

—   

the data format and data element definitions of RSE commands;

—   

a transaction example for each model (Annex B).
