S8700-series Fiber-PNC
A PKT-INT module resides on each IPSI board. LAPD links are terminated by the PKT-INT
modules in the IPSIs that are distributed out to the port networks. The non IPSI connected port
networks do not have their own PKT-INT capability, so their LAPD links are terminated by IPSIs
in the IPSI connected port networks.
Three items can be duplicated for increased reliability: server, IPSI, and PNC. They can be
duplicated independently. Duplicated control networks and duplicated IPSIs go together, so
that when the IPSIs are duplicated, the control networks must be duplicated. The set of items in
your configuration that are duplicated depend on the reliability option chosen for your system:
duplex, high or critical. See Table 303: Reliability Options.

The duplex-reliability configuration shown in Figure 92: Duplex-Reliability Configuration has
duplicated servers, an unduplicated control network, unduplicated IPSIs in the IPSI connected
PNs, and an unduplicated bearer network. Because the IPSIs are not duplicated, the PKT-INT
modules contained within them are not duplicated.
