In apartments with ADSL lines, the interface should be connected via the splitter supplied by the ISP.
ADSL is not available after the interface.
As shown in the following examples, the telephone interface can also be connected to a PABX's input

The extensions that receive calls originating from line 1 are configured in the PABX to receive calls
from the PSTN line and calls from the audio door entry system.
