In the CHANNEL A and CHANNEL B boxes:
INPUT FAIL: Red. These LEDs light up when no valid signal is present at their
corresponding inputs.
They blink when the oscillator is incapable of locking to the signal being
received. The two most common causes of this are an input signal with
excessive frequency deviation or with excessive jitter.
SIG. PRES.: Green. These LEDs light up when the signal at their corresponding
outputs is a digital version of the signal received at the input.
They blink when digital black (generated by the module) is being sent to
the outputs.
