  • Apparatus for continuous assessment of data transmission accuracy in a communication system
    Patent number: 3934224
    Abstract: A method and apparatus are disclosed for monitoring the accuracy of electronic data transmitted over a communication channel or telemetry link. Data is monitored at the transmitting point and also at the receiving point. Data monitored at the receiving point is transmitted to the data transmitting station and then compared with the data monitored at the transmitting point. Means are provided to synchronize the data monitored at two points, so that comparison is conducted over the same monitored data. After synchronization the bit error rate (BER) is calculated based on the number of miscompares that result for a given quantity of data transmitted. When the system exceeds a predetermined level corrective action is taken.
