What happens if a network cable fails during operation?
The audio processing of all the units will continue as normal, although any audio signals being passed down the network may not be available. (Warning at present, this can mean that an unexpected audio signal is routed: it is a wishlist item to ensure that network audio inputs mute if their source becomes disconnected.) The control processing will work fine for units which are still connected to each other, so there will be two sub-networks remaining which will work OK internally. Naturally, any control information which would have been routed across the failed cable will not operate correctly.
