Mixed reliability options

The reliability options separately available for each PNC method still apply except that fiber-connected PNs (fiber-PNC) with single control networks cannot be mixed with IP-connected PNs (IP-PNC) with duplicated control networks. To have duplicated control in the IP-PNC portion of the configuration, the fiber-PNC portion must have duplicated control.

The PNs in a mixed fiber-PNC and IP-PNC configuration can collectively have multiple levels of reliability. However, within the fiber-PNC portion of a system (direct, CSS, or ATM-connected PNs), all port networks must have the same reliability level --- all single control and bearer networks, all duplicated control and single bearer networks, or all duplicated control and bearer networks.

The following table summarizes the valid IP-PNC reliability options in a combined IP-PNC and fiber-PNC configuration.
