An arrangement for allowing a subscriber to select telephone features from the subscriber terminal is disclosed. The subscriber terminal includes a touch screen display and a customer premises computer. The terminal in response to a touching of the appropriate area of the screen, displays a list of all possible telephone features available to this subscriber terminal together with an indication of currently subscribed features. By touching the screen in the appropriate areas, the subscriber may select features to be added or deleted. The information regarding the subscriber selection is transmitted to the central office to which the terminal is connected. The central office maintains a set of software packages corresponding to each of the possible combinations of features to be selected by a subscriber and in response to information from the terminal defining a new set of features, the central office transmits the appropriate software package to the terminal. From then on, the terminal is reconfigured to provide the newly selected set of features. The software package includes screen display software showing feature function buttons which indicate the current set of features when the terminal is activated.
