Device block apartment

An apartment block is a subscriber unit, which usually has the appearance of a wall-mounted landline phone with a display. Traditional models are installed on the wall in the living room.

Video door phones for apartment buildings are additionally classified into analog and digital. In the case of the analog version, the data from the call panel to the apartments go through the wires, which designate both tens and units. In digital versions, apartment numbers are set in the calling unit by jumpers, while signals are sent along two wires.
