Switch 03
No FUNCTION COMMENTS
2-3 DIS/NSF detection method
Bit 3: 0, Bit 2: 0 = First DIS or NSF
Bit 3: 0, Bit 2: 1 = Second DIS or NSF
Bit 3: 1, Bit 2: 0 = Not used
Bit 3: 1, Bit 2: 1 = Disabled
(0, 1): Use this setting if echoes on
the line are interfering with the set-up
protocol at the start of transmission.
The machine will then wait for the
second DIS or NSF before sending
DCS or NSS.
If the setting is "Disabled", the bit
switch setting is used.
4 V.8 protocol
0: Off
1: Disabled
If transmissions to a specific
destination always end at a lower
modem rate (14,400 bps or lower),
disable V.8 protocol so as not to use
V.34 protocol.
0: V.34 communication will not be
possible.
If the setting is "Disabled", the bit
switch setting is used.
5 Compression modes available in transmit
mode
0: MH only
1: Disabled
This bit determines the capabilities
that are informed to the other
terminal during transmission.
If the setting is "Disabled", the bit
switch setting is used.
6-7 ECM during transmission
Bit 7: 0, Bit 6: 0 = Off
Bit 7: 0, Bit 6: 1 = On
Bit 7: 1, Bit 6: 0 = Not used
Bit 7: 1, Bit 6: 1 = Disabled
For example, if ECM is switched on
but is not wanted when sending to a
particular terminal, use the (0, 0)
setting.

V.8/V.34 protocol and JBIG
compression are
automatically disabled if
ECM is disabled.

If the setting is "Disabled",
the bit switch setting is
used.
