Introduction
In order to keep old Teleprinters running and to be able to demonstrate the surviving machines, a group of enthusiasts has setup the so-called TelexPhone project [2]. It allows telex machines to be connected to a hobbyist telex network using standard (analogue) telephone lines (POTS).


A customized modem (TxP) has been developed to convert the special Telex signals into standard modem data, allowing any standard telex machine to be connected to another telex anywhere in the world, without any modifications to the equipment at either side. This project has meanwhile evolved into TelexPhone 2, also known as i-Telex, which allows connection via the internet.
