Converting some or all ATM port networks to IP-PNC
The converted configuration
The final converted configuration can be all IP-PNC or mixture of IP-PNC and fiber connect. The
IP-PNC 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-PNC PNs can have duplicated control networks and/or duplicated bearer networks, while
other IP-PNC 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-connect
and IP-PNC 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. For
more information, see Avaya Application Solutions: IP Telephony Deployment
Guide (555-245-600) and Administration for Network Connectivity (555-233-504).
