Example #5 - Two-Wire Interface (separate network hardware):
Example #5 is conceptually similar to example #4. The difference here is that separate networks are created by providing each local
area network (LAN) with its own network switch. Therefore, traffic segmentation is physical rather than logical. Example #5 also pro-
vides an additional level of fault tolerance, although at the expense of additional network hardware. The figure shows a separate net-
work switch for QSControl.net traffic and a separate network switch for CobraNet audio traffic. All of the previous comments regarding
network expansion still apply.
