Error-checking for 5-channel telegraphic tape

The uses and the advantages of 5-channel paper tape are well recognized in the business world. Paper tape has been used for many years for message sending. Its use in telegraphic communication equipment serves as the life line of communications for many businesses. In recent years the decentralization of factory equipment and the general growth of businesses have made the transmission of accounting or scientific data between cities increasingly important. The rapidly expanding use of commercial computers and business machines will result in a further increase in the volume of data that must be communicated between cities. As more and more data are communicated, one becomes aware that a major improvement is required to refine the system, especially with regard to error handling. There is a practical limit on the improvements that may be made in transmission facilities to decrease the error rate. However, these improvements, plus a system of error detecting, could provide a highly efficient system that would be able to handle large volumes of data with a minimum amount of error-handling techniques.
