COBI DATA TRANSMISSION TESTING IN THE UNITED KINGDOM
Abstract
This analysis summarizes the data obtained during the measurement of the coded biphase (COBI) data transmission modem over the private wire services in the United Kingdom. Error statistics were recorded from June 4 to July 4, 1961. Occurrences of errors are correlated as much as possible with the daily log and its record of equipment failures and interruptions. The average bit error rate for this test was 3 bit errors in 106 bits received. As in previous tests in the U. S., the circuit was error-free for periods up to 24 hours and inoperable during some finite short periods. This test used the new COBI (Lincoln Laboratory Group Report, 25G-0035, 18 July, 1961) transmission modems for the first time. (Author)
