Abstract

The data transmission system is composed of one or more data transmitting terminals from which data are sent by way of conventional telephone lines to a central data receiving station. The data are read either from a record card or it is keyed on a ten-digit keyboard and transmitted over telephone wires to the central station where it is automatically punched in new record cards. The connection from a transmitting terminal to the central station is established through normal telephone dialing and voice communication.

The data transmission system is composed of one or more data transmitting terminals from which data are sent by way of conventional telephone lines to a central data receiving station. The data are read either from a record card or it is keyed on a ten-digit keyboard and transmitted over telephone wires to the central station where it is automatically punched in new record cards. The connection from a transmitting terminal to the central station is established through normal telephone dialing and voice communication.

The data transmitting terminal is composed of a card reader, a ten digit keyboard including several functional keys, and a speaker. Variable numerical data can be introduced into the system by pressing the ten digit keys. Numerical data can also be read from record cards by the card reader for introduction to the system. A speaker at the data transmission terminal is used to advise the operator through the use of variously coded audible signals of different operating conditions. The card reader comprises a single row of sensing brushes and a card carriage protruding from the side of the data transmission terminal. Cards are inserted individually in the carriage. The carriage is manually moved into the terminal until it strikes a carriage stop at which point a column 0 contact is closed and provides a 0 column tone that signals the terminal operator to release the carriage. As the carriage returns to its normal position, the card is r...
