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.

The signal aspect is communicated to the driver. Train can be close to the signal or hundreds of meters away. Balise communicates aspect of the signal to the train if train is close to the signal. Euroloop communicates the aspect of a signal if the train is more far away than a balise is.
