LTE filter table: 1) Normal (route), 2) Route all, 3) Block all
If the filter is set to "Block all" for area coupler Ac 15.0.0, no LTE telegrams are
transmitted between area 15 and the rest of the network.
The "Route all" setting for line coupler Lc 15.1.0 means that there is no filtering
between line 15.1 and main line 15.
If the devices in area 15 (e.g. third-party products) do not supply power to the bus,
an N125/x1 power supply unit must be installed in each line (main line 15, line 15.1
plus further lines 15.x, if applicable) for the bus power supply.
