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.

1. Any of these configurations can also have duplicated IP bearer.

Single control network only

and

Single control network only

Duplicated control network 

2

2. Not available with S8500 Servers

and

Single control network only

and

Duplicated control network

3

3. Only if the fiber-PNC portion has a duplicated control network

and

Single control network for some PNs 

and duplicated control network for 

other PNs

Duplicated control network and 

duplicated bearer network

and

Single control network only

and

Duplicated control network

and

Single control network for some PNs 

and duplicated control network for 

other PNs. Duplicated IP bearer 

network.
