Abstract An improved implementation of pre-paid telephone calling cards uses a switch-based intelligent network (IN) for automated processing of pre-paid calling card account transactions. Calling card account number, corresponding PINs, account status information and others are stored in tables maintained by one or several switches for routing calls, each switch nominally including a Service Switching and Control Point (SSCP), an Originating Call Processor (OCP), and a Terminating Call Processor (TCP).
