Composition/Operation
4.1.1 V.34 Mode Communication Procedure
V3.4 mode does not always select the transmission speed of 36.6 Kbit/s. An optimal
transmission speed will be selected according to the sequences described in the item 3
and 4 below in order to establish communication.
Transmission speed: 2.4 to 36.6 Kbit/s (by 2.4 K step)
Symbol rate: 6 rates (5 rates are supported)
3429, 3200, 3000, 2800, (2743), 2400 symbol/s
1. (CNG)
Calling tone
A monotone signal of 1100 Hz, transmitted with the period of 0.5 sec ON and 3 sec
2. (V.8)
Modem ID sequence
A 300 bit/sec signal.
This sequence exchanges information on function types and modulation methods
with a remote terminal. The following sequences will be proceeded with the modu-
lation method that both terminals have among the exchanged system information.
3. (Line probing)
Sequence to measure line characteristics.
This sequence measures the line characteristics by exchanging signals between
two modems.
The symbol rate will be determined by this sequence. This sequence will be one of
basis for data to determine the transmission sequence.
4. (TRN)
Equalizer training sequence
This sequence corresponds to the conventional procedure TCF. Sending a signal
with the fastest transmission speed specified by the remote terminal sets the equal-
izer of the modem of the receiver terminal.
5. (Control channel)
Sequence to determine modem parameters and system parameters.
A signal of 1200 bit/sec.
It corresponds to the conventional procedure of phase B.
A. A sequence for determining modem parameters
It determines the transmission speed of the primary channel by the results of the
line probing sequence and TRN (equalizer training sequence).
B. Sequence to determine system parameters
The same sequence as the conventional phase B procedure.
6. (Primary channel)
Sequence for transmitting image data.
It corresponds to the conventional phase C procedure.
7. (Control channel)
It corresponds to the conventional phase D procedure. A signal of 1200 bit/s.
Sequences between pages when there are multiple pages.
Page termination sequence.
