TELEMETERING REMOTE RECORDING UNIT

A system is disclosed for reading utility meters over a switched telephone network. In the system, information, including a telephone number is stored on a first punch card and reproduced by a card duplicator on a second initially blank punch card. The information representing the telephone number in addition to being reproduced on the second card, is also entered into a storage register. The number in the storage register is called up by an automatic calling unit and pulsed out onto a switched telephone network. The switched telephone network activates a meter reading circuit at an appropriate location represented by the telephone number. The meter reading circuit generates signals indicative of the meter reading and sends them back over the switched telephone network to be stored in the same storage register where the telephone number was entered. When the complete meter reading signal is in the storage register, the card duplicator is again activated to now receive information from the storage register. This information is then punched onto a still blank area on the second punch card. Details of the storage register and the circuitry at the meter are also disclosed.
