# Commission Decision of 30 May 2002 concerning the technical specification for interoperability relating to the control-command and signalling subsystem of the trans-European high-speed rail system referred to in Article 6(1) of Council Directive 96/48/EC (notified under document number C(2002) 1947) (Text with EEA relevance) (2002/731/EC), Division 5.2: GROUPING OF INTEROPERABILITY CONSTITUENTS

Extent: E+W+S+N.I.

The control-command interoperability constituents defined in Tables 5.1 and 5.2 may be combined to form a larger unit. The group is then defined by the functions of the integrated interoperability constituents and the remaining inter-faces on the outside of the group. The groups are defined in Tables 5.1 and 5.2. Each group has to be supported by European specifications. A group so formed is then to be considered as an interoperability constituent.
The declaration of conformity for an interoperability constituent requires that each of its interfaces referred to in Table 5 is supported by one or more European specifications. The specifications concerned will be referenced by Annex A. As long as a European specification is not available to support an interface given in Table 5, this interoperability constituent cannot be supported by a declaration of conformity. Therefore the interoperability constituent concerned shall be integrated into a group of interoperability constituents for which a declaration of conformity is then possible.
Table 5.1a
Basic interoperability constituents in the on-board control-command assembly
Definition of safety platform a building block (generic product, independent of the application) made of hardware and base software (firmware and/or operating system and/or support tools), which can be used for building more complex systems (generic applications, i.e. classes of applications). Its safety acceptance and approval shall be carried out on the basis of a ‘generic product’ (i.e. independent of the application) safety case, as specified by standard ENV 50129.
An asterisk (*) indicates that initially a European standard for the interface will not be available.
Module H2 can be applied only when a sufficient degree of confidence in the ERTMS technologies exists through return of experience from commercial installations.
