mode.
Select Bell mode answer tone. Interacts with DR bit D2
and TR bit D5.
Select CCITT mode answer tone. Interacts with DR bit
D2 and TR bit D5.
Select 1800 Hz guard tone.
Select 550 Hz guard tone.
D1 interacts with D4 as shown.

Selects 2-wire duplex or half duplex
D2 selects 4-wire full duplex in the modulation mode
selected. The receive path corresponds to the receive
mode selected by 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.
