A combined IP-PNC and fiber-PNC system can support up to 250 Media Gateways including 
the G150, G250, G350, G450, and G700.

Combined IP-PNC and fiber-PNC requires CM3.0 or later software but does not require any 
new hardware of firmware changes. The following configuration rules apply to combined 
IP-PNC and fiber-PNC configurations:

●

The current rules for IP-PNC and fiber-PNC (CSS or ATM) continue to apply. For example, 
if IP-PNC port networks are added to an existing S8700/S8710 fiber-PNC system, every 
IP-PNC port network must have one active IPSI circuit pack.

●

The current rules for IP-PNC and the rules for direct connect continue to apply. In a direct 
connect system, only one IPSI controls the direct-connect PNs.

●

There must be at least one IP Media Processor board (TN2302AP or TN2602AP) in a port 
network of the fiber-PNC portion of the configuration. The PN or PNs that contain the IP 
media processor circuit pack act as gateway port network(s) between the IP-PNC and 
fiber-PNC portions of the configuration.

Note:

The TN2602AP IP Media Resource 320 Circuit Pack is not supported in CMC1 
Media Gateways. The CMC1 supports the TN2302AP IP Media Processor board.

●

In an IP-connected port network, tone detectors (call classifiers, etc) must be engineered 
per port network bases, while in a fiber-connected CSS or ATM cluster, the tone detection 
resources can be shared over the fiber connected link.

●

There must be at least one C-LAN circuit pack in the fiber-connected portion of the 
configuration.
