2 PRINCIPLE OF OPERATION

The probe module is equipped with two Ethernet ports and an SFP optical port. The
user selects which transport stream signal input to be used by the monitoring engine,
either the Ethernet video/data port or the SFP optical input. Management of the probe
is conducted via the Ethernet management port or alternatively in-band via the
Ethernet video/data port.
