An offset-Threshold Degradation Monitor is developed which provides an operation and maintenance tool that measures the overall end-to-end performance in a Digital Communication System. The monitor derives performance information from the unregenerated partial-response waveform eye pattern found in most systems immediately prior to regeneration of the digital intelligence. Monitor performance tests indicate a sensitivity in excess of a 40 dB signal-to-noise ratio for detecting additive noise which provides degradation information 20 dB in advance of a 10 to the minus 7 power BER.
