Scenario 4 - Network with VLAN and digital interconnects
This scenario is similar to the previous scenario (on page 48), but substitutes digital
interconnects), such as AES/EBU or SPDI/F, for analog interconnects.
ƒ NION digital interface cards contain built-in sample rate converters (SRCs), which isolate
audio clock domains from each other and allow interchange of digital audio data
regardless of which clock domain the transmitting and sending devices are in.
ƒ VLAN 1 and VLAN 2 each have their own Conductor, so are in different audio clock
domains.
ƒ The SRC built into the digital interface card will allow exchange of digital audio between
the NIONs in the two clock domains.
ƒ Bypassing the SRC, which is possible, will cause errors on the AES/EBU interface.
Scenario 5 - Network with an XDAB cluster
In this scenario, digital audio is exchanged between NIONs through XDAB.
ƒ The XDAB master can be any device within the cluster.
ƒ The CobraNet Conductor can be any device outside the cluster.
ƒ Remember that all XDAB slaves and their CobraNet interfaces take their clocks from
XDAB.
