Abstract: A coin/credit operated public telephone is capable of making local, toll, and international calls using coins, credit card, or IC card and also of making a voice announcement regarding its operation method to the caller through a handset (1). Moreover, it provides graphic/character information through the LCD (10) and can transmit fault status that has been detected as a result of a highly reliable self-diagnosis carried out by receiving control signals from a remotely located central management system.
