2) when the far-end talker answers, begin speak-

the system will move to full-duplex on its own
4) full-duplex operation can be verified by a dou-
ble-talk test in which both parties speak at the
same time

talker during far-end speech, then the CS6422
is in half-duplex mode. Continue speaking in
turns until the device switches to full-duplex
mode.
