Critical-Reliability Configuration - Fiber-PNC<br />

PKT-INT (Packet Interface)<br />

The critical-reliability configuration shown in Figure 60: Critical-Reliability Configuration -<br />

Fiber-PNC has full duplication of the following options: servers, control networks, IPSIs <strong>and</strong><br />

PNCs (bearer networks). As with the high-reliability configuration, this configuration requires<br />

that IPSI connected PNs have duplicated IPSIs. Because the IPSIs are duplicated in this<br />

configuration, the PKT-INT modules are duplicated.<br />
