Avaya S8100 Series Manual page 1045

In a fiber-PNC configuration, the reliability level is an attribute of the communications system as
a whole. For IP-PNC port networks, the reliability level is an attribute of the individual PNs. The
converted communications system can include a mixture of fiber-PNC PNs and IP-PNC PNs. In
a mixed system, the fiber-PNC PNs have a single reliability level, and each IP-PNC PN has its
own reliability level. Therefore, no single reliability level can be attributed to a mixed fiber-PNC
and IP-PNC configuration.
Table 22 shows reliability options for the S8700 Series Media Server compared to reliability
options for a DEFINITY R system.
