2.9 Signals Transmitted by the Transmitter (unique to the V.8 procedure)

CM (call Menu)
It is used to indicate the available modes of modulation.
CJ (CM Terminator)
It is used to indicate the detection of JM or the end of CM.
CI (Call Indicator)
When the receiver that did not detect CM declares the use of a V.8 procedure by DIS, the
signal is sent to start the V.8 procedure (late stat).

2.10 Signals Transmitted by the Receiver (unique to the V.8 procedure)

ANSam (Modulated Answer Tone)
It is used to indicate that reception is possible using the V.8 procedure. It is a 2100-Hz
tone signal whose amplitude is modulated by 15-Hz; if the transmitter is not capable of a
V.8 procedure, it is recognized as CED.
JM (Joint Menu)
It is used to communicate the modes of modulation that may be used in relation to the
modes of modulation that are indicated by CM of the transmitter. It is also used to indi-
cate the type of terminal.

2.11 Signals Transmitted by the Transmitter (unique to the V.34 procedure)

INFO0c (INFO Sequence)
It is used to communicate modem capabilities (modulation speed, frequency transmis-
sion; 2 frequency ranges used for measurement of line characteristics, i.e., high group/
low group) and also to request adjustment.
_
B/B (Tone B/Tone B
It is a 1200-Hz tone signal used to synchronize modems. B
the phase of B by 180 degree.
L1/L2 (Line Probing Signal L1/Line Probing Signal L2)
It is a tone signal used for analysis of line characteristics in probing.
_
S/S (S Signal /S
It is a short training signal. S
PP (PP Signal)
It is used by the modem of the other party for the training of the equalizer.
TRN (TRN Signal)
It is used by the receiver to determine the speed of transmission.
1
It consists of binary 1's transmitted to declare a switch-over to a high-speed procedure.
B1 (Sequence B1)
It is a scrambled data frame transmitted at the end of start-up.
Turn-Off
It consists of scrambled 1's, transmitted for 35 msec.
