Abstract
A telephone handset is described having an array of personal service buttons thereon employed by the user to carry out microprocessor controlled communication with a personal services facility. In an access mode of operation, by depressing one button, the handset will carry out dialing followed by an automatic protocol interaction and a subsequent transmission of account code specific to the user. The program then enters an interactive mode wherein the pushbuttons of the handset can be used for A VRS activity. Programming of the handset can be carried out by the dealer or at the user facility itself through the utilization of a small simple keypad which is coupled to the handset for that purpose. When combined with a security console, a priority protocol is established wherein security related signals are given precedence over handset activity.
