are three telephones in this range (IDT 400, 410V, 415X based on and contained within the
same shell as the analogue Featurephone TX 435 or TX 445). Added components enable the
connection of one V24/X21 data device. The data components are mains driven by means of a
power cord connected to a wall mounted transformer plugged into a normal power socket.Made by GPT Ltd
