Figure 4 V.8/V.34 Control Procedure
A-4
Declares the usable modulation mode.
Declares that V.34 capability exists on
each machine, and transfers the V.34
procedures with phase 2.
After declaring the modem's modulation
speed capacity, etc. to each machine,
the receiving side determines the
modulation speed based on the results
of a probing signal output by the
transmitting side.
The transmitting side outputs a training
signal to determine the image transmission
speed.
The optimum image transfer speed is
determined by the condition in which the
training signal is received.
The pre-message protocol is done in the
same way as a normal T.30, at 1200bps.
The training signal is output with the
determined parameters, and continues to
transmit the image data.
The post-message protocol is done in the
same way as a normal T.30, at 1200bps.
