In this scenario, a CAB 8n has been added at the near end. This device provides inputs for the microphones and outputs for the speakers, and is controlled by the NioNode from across the network.
The flyoff configuration for the previous scenario has been altered so that the input from the microphone at the far end is sent to the speakers at the near end via the CM-1 interface of the NioNode (and the CAB 8n).
We are using flyoffs to connect the four microphone inputs from the CAB 8n to the inputs of the internal AEC system. The audio arrives into the NioNode via the CM-1 interface, so CM-1 flyoffs are used in the wiring.
In order for audio to be sent between the NioNode and the CAB 8n, bundle numbers have been specified on the CM-1 tab of the NioNode block and the same numbers are used on the CAB 8n tab of the CAB 8n block.
