ITU Mask .
Predefined masks can be selected, in which quality requirements regarding jitter and wander of the input signals
are defined. If the default values are exceeded, the affected input port is switched off.
Hysteresis .
To avoid that signal inputs are continuously switched off and back on when exceeding the ITU mask, a hysteresis
for switching on again can be defined. The signal input port is only reactivated when all the selected mask
points are below the defined percentage value’s limits.
Discard input signal if selected ITU mask violated .
Only if this box is selected, the input signal is switched off when exceeding an ITU mask.
