EXP-INTF (Expansion Interface Circuit Pack)
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.
Figure 28: Center Stage Switch Configuration with Duplicated PNC shows the location of EIs in
a typical two Switch Node Center Stage Switch configuration with duplicated PNC.
