Used to set the signal send level from the Modem. The
set range is 0 – 15 in the increment of 1dBm by binary
input. The value becomes – (Set value) – 5 dBm to the
actual in theory.

Used to set whether ECM (Error Correction Mode) is
performed or not. When, however, SW52-7 (V.34 mode
function) is set to OFF, or when SW52-7(V.34 mode
function is set to ON and the transmission is not the
super G3 transmission, ECM Disable setup is effective.
This is because the ECM function is indispensable in a
transmission other than super G3 transmission in V.34
mode and the other party machine may perform
checking. With SW52-7 (V.34 mode function) is ON and
this reception function is disabled.
1: YES
0: NO
Used to set whether ANSam (CED) signal send is made
or not. This is effective only when SW52-7 (V.34 mode
function) is OFF. This is because ANSam signal send is
indispensable in V.34 mode. (This machine uses the
ANSam signal also as the CED signal.)
1: YES

Used to set whether CSI signal send is perform or not.
The CSI signal includes the transmitter No.

Used to set whether non-modulation carriers are sent or
not in V.29 transmission.
