PURPOSE:To realize a telephone exchanger provided with an order trunk, through which a subscriber can order a required commodity with a telephone number. CONSTITUTION:When a subscriber 1 hooks up a handset, the subscriber is connected to e.g., an outgoing register 8 through a vacant line of a crossbar switch 7. When the subscriber 1 dials a telephone number ''80'' with a push button, a microcomputer 21 makes control to save an order trunk 16. When the subscriber 1 transmits a number corresponding to the item of a commodity and its quantity with push buttons, the number is interpreted and stored with a decoder and a memory provided at the post-stage of the trunk 16 and printed on a recording paper of a printer. A called party receiving the order can know the information such as telephone number of caller, items, quantity and date. |
