LED
An LED bank is provided to give visual indica-
tion of board status as defined by GPOUT1 and
GPOUT0. GPOUT1 is lit when the echo cancel-
ler is in half-duplex mode and dim when in
full-duplex mode. GPOUT0 indicates when the
volume control range has been exceeded by
flashing the LED momentarily.
