104 Avaya Application Solutions IP Telephony Deployment Guide
Capacity limit for media gateways
A combined IP-PNC and fiber-PNC system can support up to 250 Media Gateways including
the G150, G250, G350, G450, and G700.
Configuration rules
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:
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.
