DEDICATED TRANSMISSION PARAMETERS
COMMENTS
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.
Note that 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.
COMMENTS
If the setting is "Disabled", the current setting of G4
parameter switch 2 (bits 0 and 1) is used.
Do not change the settings.
