发明名称 Telephone data recording system
摘要 A system is disclosed for recording incoming, numerically-encoded telephone messages generated by a caller via his touch-tone or rotary dial, and successively visually displaying the messages at the called telephone. The system includes an answer actuator for capturing the telephone line in response to an incoming ringing signal, and a memory circuit for storing incoming messages. Each numerically-encoded message is stored as a data set having a predetermined number of digits in a memory capable of storing several messages. In response to read-out command signals, the messages are successively transferred to a visual display. Each message may represent a telephone number where the caller can be reached, or other information such as a numerically-encoded instruction or message.
