Method for dynamic allocation of function keys to telephone terminal functions which can be invoked by said keys

摘要

The invention relates to a method for dynamic allocation of function keys to telephone terminal functions which can be invoked by said keys, a function key controller (FST, FST') enabling or disabling the implementation of functions which can be invoked through manual actuation of individual function keys depending on the connection condition of the telephone terminal. At least some of the function keys have function-key-specific visual display devices (AF1...AFn). Depending on the connection condition of the telephone terminal, the function key controller (FST, FST') activates only those display devices (AF1...AFn) which are allocated to function keys of this type, with which individual functions can be invoked through manual actuation in the respective telephone terminal connection condition. The display devices (AF1...AFn) have in particular first display elements (AF11...AFn1) and second display elements (AF12...AFn2) which indicate not only the ability to invoke individual functions but also the invocation of functions carried out through the actuation of function keys. <IMAGE>
