ABSTRACT:
A repeater connected in a telecommunication line receiving a pseudorandom digital signal from the line is tested in-line by superimposing a noise signal of steadily increasing amplitude on the digital signal and measuring the amplitude of the noise signal at an output of the source of the noise signal when the amplitude of the noise signals produces a predetermined number of errors in the digital signal at the output of the repeater.
