DC SC2020
Version 1.1
Stops after the signal with amplitude of 2100Hz modulated by15Hz is being sent continuously
for 4sec, or once CM is detected. Fax without Super G3 capability is detected as CED.
CM (Calling Menu Signal):
300bps signal (*) that declares the modem mode that can be used at outgoing terminal.
JM (Joined Menu Signal):
Stops when 300bps signal, which declares the modem mode that can be used on the outgoing/
incoming terminal, and CJ are detected (For CM or JM FIF, refer to No. 2 'V.8 CM/JM Signal')
CJ (CM terminator):
Continuation of 300bps and 3 octet '0' by signals which indicate the end of CM and verify JM.
NOTE2 Signal Names and Contents
V.34ph2 (Phase 2): Probing
Measures the line attribute using Probing signal.
V.34ph3 (Phase 3): Equalizer Training
Set up the modem equalizer by the TRN signal
V.34ph4 (Phase 4): Final Training
Determines the signal speed
(V.34 Phase 1 is V.8 procedure)
This section (Phase 2 to 4) is automatically performed by the modem at the outgoing and incoming
terminals. Send Level, Equalizer, and Modulator Speed are determined. The value determined here
takes precedence over the NSF/DIS contents.

6.6.5.2 V.8 CM/JM Signal
FIF configuration (Table 1) of CM and JM signals used in V.8 and the details of every bit are as follows.
V.8 is the standard that decides the procedure for modem with multiple capabilities to auto select the opti-
mal mode corresponding to the line condition.
