The EUROSIG specifications were subsequently updated by the UNISIG Consortium 4 in consideration of further technical work in development and test areas. The UNISIG technical documents were finally submitted to the CENELEC WGA9B group for review, integration, and consolidation. The main body of Part 1 of this Norm, and the relevant Annexes designated as normative, constitute the mandatory requirements for achieving air-gap interoperability between any possible combination of wayside and train-borne equipment. Annexes designated as informative, either provide background information for the mandatory requirements, or outline non-mandatory requirements and optional functionality. Part 2 of this Norm (UNISIG SUBSET-085) specifies test methods and tools for verification of compliance with the mandatory requirements of Part 1 (this document) The EUROSIG Consortium was composed of the following European Companies working in the Railway Signalling area: ACEC Transport, Adtranz Signal, Alcatel SEL, GEC Alsthom Transport, Ansaldo Trasporti, CSEE Transport, SASIB Railway, Siemens, and Westinghouse Signal. UIC: Union Internationale de Chemins de Fer. EEIG ERTMS User Group: European Economic Interest Group was composed of some European Railways managing the implementation of ERTMS/ETCS trial sites aimed at full functional verifications. The UNISIG Consortium was composed of the following European Companies working in the Railway Signalling area: Adtranz Signal, Alcatel, Alstom, Ansaldo Signal, Invesys Rail, and Siemens.

Step G2.3 Step G2.4 Step 4 170 Page 10 of Introduction 1.1 Application Range This Norm is part of the overall set of normative background that constitutes the basis for the European Union Directive 96/48/EC on Trans-European High Speed Railway Network Interoperability, and for the relevant Technical Specification for Interoperability (TSI). The TSI (Technical Specification for Interoperability) defines the concept of Technical Interoperability that applies to the Constituents of the Control-Command Sub-System. As far as the Balise Location and Transmission System is concerned, the wayside Balises and the complete onboard ATP/ATC equipment, including the Balise Location and Transmission Functionality, are interoperability Constituents considered in this Norm. 1.2 Scope The present Norm considers requirements and performance for wayside and On-board transmission units, interacting for a reliable and safety related data transmission between track and train. These units are the Balises, (standing alone fixed data Balises, or controlled data Balises linked to the wayside signalling system) and the On-board Antenna Units integrated with the transmission functionality of the overall On-board ATP/ATC equipment. The Norm considers specific application and environmental conditions for Balises and Antenna Units (e.g., installation constraints and debris) that may have a direct impact on the achievable transmission performance. It also defines constraints and conditions for the external interfaces of the Eurobalise Transmission System with other interacting equipment, both wayside and On-board. A detailed Coding Strategy involving telegram generation, transmission, and reception, covers the issue of statistical data protection against random error conditions in the entire communication path. Requirements of compatibility or interoperability with earlier generations of ATP/ATC transmission systems, using similar electrical characteristics, are explicitly defined in order to allow an easy transition from those systems to the new Norm. Applicable sub-clauses of existing European Norms that cover issues of general interest (e.g., environmental conditions), that are deemed relevant for the purposes of an interoperable track-train data transmission, are also considered. The Norm specifies detailed functional and non-functional requirements for the Balise, identified as a basic wayside constituent of interoperability. A special focus is given to the air-gap interface, where the Balise interacts with the On-board equipment. The air-gap requirements for the Balise have been defined in all needed details in order to serve as a solid basis for the interoperability with any ERTMS/ETCS compliant On-board equipment. The interface of the Balise with the wayside equipment has also been considered for the purpose of interchangeability of wayside components. The Norm specifies a set of functional and non-functional requirements for the transmission parts of the Onboard equipment, which are deemed indispensable for the purpose of interoperability. The mandatory requirements, applicable to the Balise location and transmission functionality, integrate other mandatory requirements specified for the ERTMS/ETCS On-board equipment by correlated Norms. Also in this case, a special focus is given to the air-gap interface, where the On-board Antenna Unit interacts with the wayside Balise. Page 11 of 170 Compared with the Balise case, only a minimum set of mandatory requirements has been defined for the Onboard equipment. This allows any kind optimisation, in costs and performance, for the overall architecture of the On-board system, while still ensuring interoperability. Finally Part 1 of the present Norm, in a general way outlines methods, procedures, and tools required for compliance verification of the Eurobalise products. More detailed requirements on test, test procedures, and test tools are given in Part 2 of the Norm. The present Norm does not explicitly consider the following issues, because they are already considered by the correlated specifications: Contents and structure of the user data exchanged between track and train (see UNISIG SUBSET-026); The Interface between the transmission functionality and the rest of the On-board ATP/ATC system (see UNISIG SUBSET-031); Quantitative RAMS performance regarding the transmission functionality of the On-board equipment (see UNISIG SUBSET-088). Whenever referring to Part 2 of this Norm, it means referring to UNISIG SUBSET-085. In a similar way, Part 1 refers to this document.

The On-board Transmission Unit, with the main functions to transmit signals to and/or receive signals from the Balise through the air gap. A wayside Transmission Unit that uses the Magnetic Transponder Technology. Its main function is to transmit and/or receive signals through the air gap. The Balise is a single device mounted on the track, which communicates with a train passing over it. In this Norm, Balise is used as a short word for Eurobalise, unless otherwise stated. The zone outside the Contact Zone and the Side lobe Zone, where less stringent requirements on Up-link field conformity with the reference field is defined for the Balise. One or more Balises that on a higher system level together create a quantity of information related to the location reference in the track, the direction of validity of data, and train protection information. This is the location in the track where spot transmission occurs. The information part of the Balise Telegram (i.e., the telegram without CRC, control bits, and synchronisation bits), i.e., the user bits. These correspond to the centre of symmetry of the Balise radiation pattern. The Balise Telegram located in the Balise Data. The telegram consists of information, CRC, and synchronisation bits. An On-board module for intermittent transmission between track and train, that processes Up-link as well as Down-link signals and telegrams from/to a Balise. It interfaces the ERTMS/ETCS Kernel and the Antenna Unit. An On-board function that processes Up-link and Down-link data, and that interfaces the ERTMS/ETCS Kernel and the On-board Antenna Unit. This is not necessarily a physical device, and it is not a Constituent itself (but is part of the ERTMS/ETCS On-board Constituent). One or more Balises that seen from the vehicle, regardless of the contained information, are close to each other. The definition of close is dependent on the maximum line speed. Compatibility between two systems means that they can coexist under defined conditions without interfering with each other as to specified functions.
