The combinations of two coded signals are used for the selection of the terminal equipment block selectors while one code signal is singly used for selecting one of the terminal equipments. According one aspect of the present invention the terminal equipments having special instruction codes recorded therein are inserted into the groups and blocks to facilitate the switching of readings from one group or block to another.
