ABSTRACT:
The method is for controlling performance features of an exchange. In step a) a static table of performance feature object codes, having corresponding code values, is transmitted from the exchange to a terminal equipment during an equipment initialization. The static table of performance feature object codes is specific for the exchange and contains all performance features available in the exchange. Information for the specification of the performance feature object is allocated to each performance feature object code value. In step b) the static table of performance feature object codes is stored in the terminal equipment. In step c) a dynamic table of performance feature object codes, which correspond to the performance features that can be activated in the respectively current switching-oriented state of the terminal equipment, is transmitted from the exchange to the terminal equipment. In step d) the performance features of the current switching-oriented state are displayed by the terminal equipment, according to the dynamic table of performance feature object codes. In step e) the desired performance feature is selected in the terminal equipment. In step f) the selected performance feature is acknowledged through transmission of the corresponding performance feature object code value from the terminal equipment to the exchange. In step g) the switching-oriented state corresponding to the selected performance feature is altered, and then a return is made to step c).
