Figure 63

 shows the location of EIs in a typical center stage switch configuration with 

unduplicated PNC.

For an unduplicated center stage switch configuration, only one EI is needed in each PN. 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 a PN 
through an EI circuit pack.

on page 1180 shows the 

location of EIs in a typical two Switch Node Center Stage Switch configuration with duplicated 
PNC.
