Failure cases:
• damaged AESOP connection between amp n and n+1:
the audio and ethernet continuity is preserved thanks
to the real-time switch of the AESOP stream toward the
uncorrupted source coming from the trailing amplifier.
• damaged AES3 input connection: no sound inter-
ruption would be heard because the failured input is
immediately replaced by the AESOP stream. Ethernet
connectivity is not affected by this kind of failure.
• damaged Etehrnet input connection: no data corruption
would occur because the failured input is immediately
replaced by the AESOP stream. The audio stream is not
affected by this kind of failure.
Even if this network configuration implements both data
and audio redundancy, its robustness is the same as that
of the previous topology: Connectivity of data and audio is
garanteed in case of 1 single cable failure only (redundancy
of first failure type).
