Networked System
A networked system with multiple nodes uses an NIU (network interface unit) to combine up to 24 CM9700-CC1 systems into a network—each
CC1 system is called a “node.” Multiple CM9770-MXB units can be connected to each CC1 through sideframing and downframing. An NIU is a
CM9700-CC1 loaded with networking software, sold as a CM9700-NW1. Refer to Figure 16.
