Lineside Electronic Unit (LEU) ‒ a trackside electronic unit that interfaces the national trackside signalling / interlocking equipment with Eurobalise and Euroloop .

Loop ‒ track mounted device for the transmission of data between track-to-train .

Euroloop ‒ a semi-continuous, intermittent transmission system. It provides signalling in-fill information in advance as regards the next main signal in the train running direction as soon as they become available [EU Subsystems and Constituents of the ERTMS].

In ETCS Level 1 (Figure 5-1) a signal is usually connected to the Euroloop via LEU.
