1 Descriptions BCS II Simplex Repeater User Manual System-Level Application The simplex repeater regenerates DS3, E3, and STS-1 signals to equal level point over a distance of up to 900 ft (using RG-59/734 cable). Two repeaters are required to regenerate both the send and receive signals and complete the cross-connect. The repeater regenerates the signal that appears on the IX port and transmits it out the I port for a length dependent upon the type of cable used.
