SW5 No. 1, No. 2 Auto dial mode delay timer of before line
connect
Delay time between the dial key input and line connection under the
auto dial mode.
RAPID01 CML RELAY ON
No.1 No.2
0 0 0sec
0 1 1.5sec
1 0 3.0sec
1 1 4.5sec
SW5 No. 3 Sender's information transmit
When it is set at "0", sender's name, sending page number and so on
are automatically printed in the recording paper on the receiving side
during transmission. Thus, the sender can be known on the receiving
side.
0: Applied
1: Not applied
SW5 No. 4 Footer print
When set to "1", the date of reception, the sender machine No., and the
page No. are automatically recorded at the end of reception.
SW5 No. 5 ECM MMR
See SW 2 No. 3.
SW5 No. 6, No. 7 Reserved
Set to "0".
SW5 No. 8 CSI transmission
CSI signal contains the sender's phone number registered in the ma-
chine. If this switch is set to "1", no sender's name will be printed at the
receiving side.
SW6 No. 1 H2 mode
Used to determine reception of H2 mode (15 sec transmission mode).
When set to OFF, H2 mode reception is inhibited even though the trans-
mitting machine has H2 mode function.
SW6 No. 2 ~ No. 4 Reserved
Set to "0".
SW6 No. 5 ~ No. 8 Modem speed (DCS data reception speed)
Used to determine the initial modem speed. The default is
14400BPS(V.17). It may be necessary to program it to a slower speed
when frequent line fallback is encountered, in order to save the time
required for the fallback procedure.
SW7 No. 1 Forced 4800bps reception
When line conditions warrant that receptions take place at 4800 BPS
repeatedly.
It may improve the success of reception by setting at 4800 BPS.
This improves the receiving document quality and reduces handshake
time due to fallback during training.
SW7 No. 2 Protect from echo
Used to protect from echo in reception.
SW7 No. 3 DIS receive acknowledgement during G3 transmission
Used to make a choice of whether reception of NSF (DIS) is acknowl-
edged after receiving two NSFs (DISs) or receiving one NSF (two DISs).
It may be useful for overseas communication to avoid an echo sup-
pression problem, if set to "1".
SW7 No. 4 Non modulated carrier for V.29 transmission mode
Though transmission of a non-modulated carrier is not required for trans-
mission by the V29 modem according to the CCITT Recommendation,
it may be permitted to send a non-modulated carrier before the image
signal to avoid an echo suppression problem.
It may be useful for overseas communication to avoid an echo sup-
pression problem, if set to "1".
DIALLING
SW7 No. 5 EOL detect timer
25 seconds or 13 seconds are selected for the detection timer of EOL
(end of line). This is effective against communication trouble on a spe-
cific type of long EOL.
0: 13 seconds
1: 25 seconds
SW7 No. 6 Protocol monitor
Normally set to "0". If set to "1", communication can be checked, in case
of trouble, without using a G3 tester or other tools.
When communication FSK data transmission or reception is made, the
data is taken into the buffer. When communication is finished, the data
is analysed and printed out. When data is received with the line monitor
(SW07 No.7) set to "1" the reception level is also printed out.
SW7 No. 7 Line monitor
Normally set to "0". If set to "1", the transmission speed and the recep-
tion level are displayed on the LCD. Used for line tests.
SW7 No. 8 Length limitation of copy/send/receive
Used to set the maximum page length.
To avoid possible paper jam, the page length is normally limited to 1m
for copy or transmit, and 1.5 meters for receive.
It is possible to set it to "No limit" to transmit/receive a long document,
such as a computer print form, etc. (In this case, the receiver/transmit-
ter must also be set to no limit.)
SW8 No. 1, No. 2 Digital equalization setting (Reception)
The specific line equalizer is inserted.
No. 1 No. 2
0 0 The line equalizer built in the modem is turned off
0 1 Line equalizer corresponding to 1.8 km
1 0 Line equalizer corresponding to 3.6 km
0 1 Line equalizer corresponding to 7.2 km
SW8 No. 3 Dial pausing (sec/pause)
Pauses can be inserted between telephone numbers of direct dial con-
nection. Selection of 4 sec or 2 sec pause is available.
SW8 No. 4 ~ No. 8 Signal transmission level
Used to control the signal transmission level in the range of –0dB to
–31dB.
SW9 No. 1, No. 2 CED tone signal interval
For international communication, the 2100Hz CED tone may act as an
echo suppresser switch, causing a communication problem. Though this
soft switch is normally set to "00", it should be change the time between
CED tone and DIS signal from 75ms to 1000ms to eliminate the commu-
nication problem caused by echo.
SW9 No. 3 Equalizer freeze control (MODEM)
This switch is used to perform reception operation by fixing the equal-
izer control of modem for the line which is always in an unfavorable
state and picture cannot be received. Usually, the control is executed
according to the state of line where the equalizer setting is changed
always.
SW9 No. 4 Equalizer freeze control 7200bps only
Setting which specifies SW9 No.3 control only in condition of 7200bps
modem speed.
SW9 No. 5 Protocol monitor (Error Print)
If set to "1", protocol is printed at communication error.
SW9 No. 6 Reserved
Set to "0".
SW9 No. 7 Dial tone detection (before auto dial)
Used to set Yes/No of dial tone detection in auto dialing.
