ABSTRACT:
A method and apparatus for operating a lottery system. Customers purchase lottery entries using their customer stations to send lottery entry data to a toll switching system equipped to prompt customers and accept lottery entries. Customer identification data for identifying purchasers is transmitted to that toll switching system in the form of automatic number identification signals from switching systems connected to the customers and personal identification codes keyed by customers. Lottery data is stored in the toll switching system and transmitted to a centralized lottery data base system for determining lottery winners. Advantageously, customers may purchase entries in existing, periodic draw lotteries from their own customer stations, using the shared facilities, and the high peak capacity for handling lottery traffic of a public switched network.
