Figure 8-36. Center Stage Switch Configuration with Unduplicated PNC
For an unduplicated stage switch configuration, only one EI is needed in each port
network. Notice that there is no direct connection between the PNs, rather every
inter-PN connection is made through the center stage switch. Each SNI in the
switch node carriers can be connected to an PN through an EI circuit pack.
