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.
