Send Mixes:
Each far end signal is routed to the
opposite far ends, but not back to itself (mix-minus).
AEC output: Contains the local microphone signals
after the echo cancellation is applied, which is sent to
the far ends along with the far end signals.
AEC Reference Mix:
The far end signals are routed
to the input of the AEC to enable acoustic echo
cancellation.
For a Single Far End Connection
When a single far end connection is all that is needed,
one crosspoint provides the AEC Reference and
another is used to route the AEC Output to the far end.
