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. 7 (–12
dBm) 0
6 1

8 1
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
4 DIS reception
check in G3
send Used to set whether DIS reception is checked or not in
G3 mode. Once
when
receiving
NSF,
twice
when
receiving
DIS 0
5 None-
modulation
carrier in V.29
send Used to set whether non-modulation carriers are sent or
not in V.29 transmission. NO 0
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. 75 ms 0 If either of SW6-
7 or SW6-8 is
effective, open
of the line after
completion of
communication
is delayed by
1.5 sec.
8 Countermeasure
for echo in
transmission Used to set the time interval from DIS reception to DCS
signal sending. 200 ms 0
