On the rear of the IMG 2020 are three redundant ethernet interfaces labeled CTRL 0/1, DATA A0/A1, and DATA B0/B1. Each of these interfaces can be configured so that they can pass IP packets. When configured, the interfaces can pass IP information for Services such as SIP or H.323 Signaling, Multimedia signaling, M3UA Signaling, NFS, RADIUS, and SNMP. The interfaces can also be configured to pass Media Info such as audio (RTP) or video data. Each individual interface is configured under the IP Network > Logical Interfaces object. Within the IP Network object, the IP Firewall field enables and disables the Denial Of Service functionality. To create the IP Network object, right click on the IMG 2020 physical node object and select New Network.
