The video resolution and frame rates that are specified in this screen are used only during a failure.
Because the failover ISP can back up different video ports from different ISPs, this setting does not
necessarily match the original setting of the primary ISP. Setting all encoder ports to a high video
resolution and frame rate guarantees that video quality is maintained during a failure.
Figure 34. Port Configuration
For this example, Table 8 shows how the first eight ISP encoder ports have been assigned to the
first eight matrix output ports. All ports are configured with video resolution of 4 CIF and frame rate
of 30 fps. A second failover ISP in the network would use different matrix output ports.
