ABSTRACT:
A fault location arrangement for either electrical or optical digital transmission systems is provided by a distinct diagnostic signal at each of a series of regenerators which is used to modulate data signals. The modulated data signals are then recovered by demodulation and analyzed to determine the status of each regenerator. Diversion of signals by "loop-back" at each regenerator is also provided for.
