Abstract :
AT 9 P.M. Eastern Standard Time on August 31, 1962, the largest system-wide cutover in the history of telephony took place. On that date, some 60,000 teletypewriter exchange stations (TWX) in the United States were successfully cut over to dial operation. This paper describes dial TWX service and some of the engineering considerations that made the project the success it was.
