Abstract
A telephone set-computer terminal assembly is provided having a single decimal keyboard and a switchable local supply. The telephone interface, connected to the decimal keyboard, is supplied by its line input through a switching relay which connects it at one time to a local power supply of the man-machine interface equipment and at another to the line through a switch depending on whether the line is unlooped or not. The telephone interface is connected to the man-machine interface equipment by message communication lines comprising a galvanic insulation device.
