It is already mentioned voice switch is necessary
for the hands-free conversation. Here, we explain
the principle of the voice switch circuit used in the
EXES-6000 system. The voice switch circuit
mentioned here is an improved version of one
that is used in the EXES-5000 system.
The voice switch is employed in the DL unit and
its operations differ depending on the conversa-
tion mode (hands-free or handset) between the
stations.
