Division 5.2.2 Grouping of interoperability constituents

The Control-Command basic interoperability constituents defined in Tables 5.1.a and 5.2.a may be combined to form a larger unit. The group is then defined by the functions of the integrated interoperability constituents and the remaining interfaces to the outside of the group. If a group is formed this way, it shall be considered as an interoperability constituent.

• Table 5.1.b lists the groups of interoperability constituents of the On-board Assembly

• Table 5.2.b lists the groups of interoperability constituents of the Track-side Assembly

When the mandatory specifications indicated in this TSI are not available to support an interface, a declaration of conformity may be possible by grouping interoperability constituents.
