5 Signal send
level
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.

SW6 1 ECM 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.
YES 1 Setup in
communication
other than V.34
2 ANSam (CED)
signal send
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.)
YES 1 Effective only
when V.34
mode function
are disable.
3 CSI send Used to set whether CSI signal send is perform or not.
The CSI signal includes the transmitter No.
YES 1

Used to set whether DIS reception is checked or not in
G3 mode.

5 None-
modulation
carrier in V.29
send
Used to set whether non-modulation carriers are sent or
not in V.29 transmission.

6 EOL detection
timer
Used to set the detection timer of EOL (End Of Line) in
phase C reception.
13 sec 0
7 Countermeasure
for echo in
reception (CED
toner send
interval)
Used to set the time interval from CED sending to FSK
signal sending of DIS.

7 or SW6-8 is
effective, open

completion of
communication
is delayed by

transmission
Used to set the time interval from DIS reception to DCS
signal sending.
