Converting some or all direct-connect port networks to IP-connect
The converted configuration
The final converted configuration can be all IP-connect or a mixture of IP-connect and
fiber-PNC. For systems that are controlled by the S8500 media server, only simplex reliability,
no duplication, is available.
For systems that are controlled by the S8700-series Media Server, the IP-connect components
can have high reliability, duplicated control networks and a critical reliability duplicated bearer
network. The reliability level for the fiber-PNC portion of the converted system can also be
duplex, high, or critical. The reliability level of the IP-PNC portion of the converted system is per
PN and can be either duplex, high, or critical. That is, some IP-connect PNs can have
duplicated control networks and/or duplicated bearer networks, while other IP-connect PNs
have nonduplicated control networks.
If synchronization is required for any of the IP-PNC PNs, the synchronization source must be
administered separately for each IP-PNC PN.

Important:
Avaya recommends that you perform a traffic analysis when changes from a
Important:
fiber-PNC configuration to a mixed configuration that includes both fiber-PNC
and IP-connect PNs. A traffic analysis helps you understand Inter-PN bearer
traffic and determine the correct number of media processor resources, other
network parameters such as the use of network regions, codec sets, and VLANs.
