Dedicated Transmission Parameters
If "inch only" is selected on the machine uses
inch-based resolutions for scanning, the printed
copy may be slightly distorted at the other end if
that machine uses mm-based resolutions.
If the setting is "Inch-mm conversion available ",
Inch-mm conversion become effective to the
special senders.
If the setting is "Disabled", the bit switch setting is
used.
(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.
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.
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.
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.
