Abstract : Rome Air Development Center's Digital Communications Experimental Facility (DICEF) has conducted a test and evaluation of the AUTOVON which has revealed the analog and digital characteristics of the system. The Digital tests incorporated various different modems and established that most of the errors occur in bursts because of the transient perturbations of the AUTOVON, and because of modem modulation and scrambling techniques. The Bit Error Rate (BER) of the digital transmission is affected by these bursts more than Throughput. Since Throughput is a measure of the actual message transfer rate of a digital system, both BER and Throughput should be measured when testing a digital system. The report discusses the importance of Throughput and its relationship to BER, how Throughput is measured, and construction of a device to aid Throughput measurements. (Author)
