Abstract

In order to give identity to, and select one of a number of function units, included in a stored program controlled telecommunication system, a control unit during its control period, generates and sends to an information bus an identification number assigned to the function unit. The function unit uses an access signal from an addressing unit, if the control period occurs during starting the system, for actuating a register connected to the information bus and arranged in the function unit for storing the identification number. The function unit converts the access signal, if the control period occurs during operation of the system, to a selection signal only if the identification number obtained from the bus agrees with that stored in the register. The function unit uses the selection signal for activating the reception of control information intended for the function unit.
