"Register", but not linked
A '''sender''' was a circuit in a 20th century electromechanical [[telephone exchange]] which sent [[telephone number]]s and other information to another exchange. In some American exchange designs, for example [[1XB switch]] the same term was also used to refer to the circuit that received this information. The corresponding device in the British [[director telephone system]] was called a "director" and, in other contexts, "register".
