Abstract

A telephone terminal designed for public use to be installed inside premises having total network access, which can be connected to any type of exchange or switchboard. It is comprised of a set of circuits contained on a single circuit board with the corresponding advantages of installation and maintenance, it is electrically energised from the line and has been designed so that it can be used with different types of intelligent cards currently in existence (electronic coin carrier, EPROM and EEPROM). Furthermore, it enables the loading of parameters and programs, as well as maintenance from a remote centre. Figures 1 and 2 show representative block diagrams of the circuit corresponding to the equipment of the invention. The set of circuits necessary for the proper functioning of the set in the above-described manner is constructed around a microcontroller unit which includes a microprocessor 1 and several pin expansion peripherals which provide the set of inputs and outputs necessary for controlling the different functions to be carried out by the other peripherals. <IMAGE>
