Avaya S8700-series Media Servers
Issue 6 February 2007 87
● ATM Switch (duplicated control networks)
● ATM Switch (duplicated control and bearer networks)
Connectivity when sending voice bearer over IP
The following connection methods are available with IP-PNC configurations:
● IP-PNC (single control network)
● IP-PNC (duplicated control network)
In addition, a single MCC1 cabinet can be configured to house multiple PNs that use the voice
bearer over IP configuration.
Note:
Note: When using IP-PNC between PNs, video cannot be sent directly between port
networks. In this case, video calls must be routed through the public network and
back into the media server’s network.
Combining IP- and fiber-PNC port networks
An S8700-series Media Server supports only one type of configuration from the list of available
direct-connect, CSS, or ATM configurations. However, the two IP-PNC configurations can be
mixed together, and either or both of the IP-PNC configurations can be mixed with any one of
the direct-connect, CSS, or ATM configurations.
High-level capacities
The S8720/S8710 Media Server provides a large scale solution with a high number of
endpoints.
