Abstract
An integrated customer owned coin operated telephone (COCOT) and regulated paystation telephone system permits the functionality of the paystation to be remotely programmed, in order to increase the versatility of the paystation in either mode of operation. The integrated paystation telephone system includes a central microprocessor coupled with a memory that stores the firmware for operating the paystation telephone. Circuitry is provided under the control of the microprocessor to operate such functions as the power control and coin relay (the relay which excepts or refunds a deposited coin) in either mode of operation. The paystation telephone system is remotely configured to operate in either the COCOT or regulated mode without requiring any hardware changes. Because of the remote configuration of the paystation telephone system, various features can be programmed, increasing the versatility of the paystation.
