ÖNORM EN ISO 12855

This document specifies: - the interfaces between electronic fee collection (EFC) back-office systems for vehicle-related transport services, e.g. road user charging, parking and access control; - an exchange of information between the back end system of the two roles of service provision and toll charging, e.g.: - charging-related data (toll declarations, billing details), - administrative data, and - confirmation data; - transfer mechanisms and supporting functions; - information objects, data syntax and semantics. This document is applicable for any vehicle-related toll service and any technology used for charging. The data types and associated coding related to the data elements described in Clause 6 are defined in Annex A, using the abstract syntax notation one (ASN.1) according to ISO/IEC 8824-1. This document specifies basic protocol mechanisms over which implementations can specify and perform complex transfers (transactions). This document does not specify, amongst others: - any communication between toll charger (TC) or toll service provider (TSP) with any other involved party; - any communication between elements of the TC and the TSP that is not part of the back-office communication; - interfaces for EFC systems for public transport; - any complex transfers (transactions), i.e. sequences of inter-related application data units (ADUs) that can possibly involve several application protocol data unit (APDU) exchanges; - processes regarding payments and exchanges of fiscal, commercial or legal accounting documents; and - definitions of service communication channels, protocols and service primitives to transfer the APDUs.
