17 Compact Infinity Core
• Is the core currently controlled (e.g. by a desk) ? Or has it no control ?
• Are all SFP equipped A-Link ports active ?
• Are dropouts occuring in the audio processing ?
If at least one of these criterias is not met, the QoS of the A-Link signal gets
reduced. Each D23m frame then switches to the A-Link port (main or redun-
dant) with the better QoS value.
With the Infinity Core, the customer can decide the level of redundancy.
If A-Link cable redundancy is desired, two Infinity Cores have to be deployed.
Then, of course also core redundancy is provided : should an audio dropout
occur within the main core, the QoS of the A-Link signal is reduced and
therefore the D23m frame switches to the redundant port where the redundant
core is connected. In this case, also the active core would be switched from
main to the redundant. Also in case of a hardware failure of the core, the red-
undant core will take over the processing immediately without any audible
disturbance.

Other Infinity Core system redundancy features are : redundant fan system,
redundant power supplies, redundant control link between core and console.
If a complete re-imaging or factory reset of the core is required, this can be
done using a bootable USB stick and connect a monitor to the VGA port and
a keyboard to the USB port. The USB stick contains software to re-image the
core and some further tools for diagnostic purposes like memory checkers.
Software updates and general support is managed from the Vista desk using
