Division 6.2.1.2 Functional integration verification of Track-side Assembly

The verification is to be made for a Control-Command Track-side Assembly installed on an infrastructure. For the Control-Command equipment that is not defined as Class A only the verification requirements associated with interoperability (for example EMC) are included in this TSI.

Before track-side functional verification can take place the interoperability constituents included in the assembly shall have been assessed in accordance with section 6.1 (Interoperability constituents) above and have an EC declaration of conformity. The notified body shall verify that they are suitable for the application (e.g., optional functions implemented).

Class A functionality already verified at interoperability constituent level does not require additional verification.

For the design of the ERTMS/ETCS part of the Control-Command Track-side Assembly, TSI requirements must be complemented by national specifications covering e.g.,

• the description of the line, characteristics such as gradients, distances, positions of route elements and Eurobalises/Euroloops, locations to be protected, etc.

• the signalling data and rules required to be handled by the ERTMS/ETCS system.

The integration verification tests shall be performed to demonstrate that the components of the assembly have been correctly interconnected and interfaced to national track-side equipment to ensure that the required functionality and performance of the assembly necessary for that application is achieved.

The following track-side interfaces shall be considered:

• Between the Class A radio system and the ERTMS/ETCS (RBC or Radio In-fill Unit, if relevant)

• Between Eurobalise and the LEU

• Between Euroloop and the LEU

• Between neighbouring RBCs

• Between the ERTMS/ETCS (RBC, LEU, Radio In-fill Unit) and Interlocking or national signalling, as relevant

The following shall be verified:

• correctness of installation of the ERTMS/ETCS part of the Control-Command Track-side Assembly (e.g. compliance with engineering rules, co-operation of interconnected pieces of equipment, absence of unsafe interactions and, where required, storage of application specific data according to the above mentioned national specifications).

• correctness of operations at the interfaces with national Track-side equipment.

• ability to interface with an On-board Assembly with corresponding characteristics (e.g., ETCS application level)
