Duplex-Reliability Configuration
The duplex-reliability configuration shown in Figure 8-74 has duplicated media
servers, an unduplicated control network, unduplicated IPSIs in the
IPSI-connected PNs, and an unduplicated bearer network. Since the IPSIs are not
duplicated, the PKT-INT circuits contained within them are also not duplicated.
