D2 selects 4 wire full duplex in the Modulation mode
selected. The receive path corresponds to the ANS/ORIG
bit CR0 D0 in terms of high or low band selection. The
transmitter is in the same band as the receiver, but does
not have magnitude filtering or equalization on its signal
as in the receive path.
NOTE:
DTMF0 - DTMF2 should be set to an appropriate state after DTMF dialing to avoid unintended
operation.
