From: Roland Vossen <rvossen@xxxxxxxxxxxx>
Transmit was muted in two ways: full mute and a partial mute called
'pre ism cac time' mute. But, this 'pre ism cac time' mute was done at
one place in the code (when tx_mute == false), and overridden later
on in another place in code.
To fix this, the 'pre ism cac time' mute has been replaced by a non
mute.
