Zusammenfassung:The operation of a data communication system having a central transmitter and receiver and a data set transmitter and receiver, usually remotely positioned, can be tested by connecting a frequency converter between the data-set transmitter output and the data set receiver input so that signals from the central transmitter to the data set transmitter are returned by the data set receiver back to the central receiver. The data transmitted by the central transmitter can be compared with the data received by the central receiver to provide an indication of the operation of the data communication system.
