These circuits enable the acceptance of data from a magnetic stripe reproducing terminal in pulse rate modulation (PRM) or F/2F data format at conventional terminal speeds and the transmission of this data, without changing the format, over voice-grade telephone lines at compatible Speeds. Data from a terminal device, such as a magnetic stripe card data reproducing device, is applied to a data rate generator circuit 12.
