There 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.

Normal telephone line conditions exist, there is no requirement for specialist testing.

There are two wiring constraints that MUST be adhered to if data corruption is to be avoided:

a) No wiring stubs (unterminated untwisted pair)
b) Secondary line jacks ONLY, NOT primary/master jacks.
