S8700 MC
On S8700 Multi-Connect, 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.
S8700 Multi-Connect architecture has three items that can be duplicated for increased 
reliability: media 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 
Duplex-Reliability Configuration
The duplex-reliability configuration shown in 
page 1807 has duplicated media 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.
