General
Version 1.0
6.8.5.1 Super G3 Fax
In 1996 ITU-T, [Super G3 Fax] is recommended.[Super G3 Fax] supports 28.8Kbps Fax com-
munication, has modem capability of V.8 and V.34, and its protocol consists of V.8 and V.34
parts....33.6Kbps is also available as an option. With [Super G3 Fax], 28.8Kbps communication
with the other companies Fax is made possible, and so is the communication with the conven-
tional 14.4K/9600 bps G3 Fax.
• When communicating via [Super G3] mode, [SG3] is recorded in the Report Mode col-
umn.
• [Super G3] Image Information Transmission is performed in 'ECM (Error Correction
Mode)'.
• V.34 is the standard for 28.8K (option: 33.6K) to 2400 bps modem; V.8 is the standard for
deciding on the procedure to select the optimal mode for the preceding line condition to
V.34.FIF configuration (Table 1) of CM and JM signals used in V.8 and the details of every
bit are as follows.
[Super G3 Fax] can communicate with conventional Fax in standards other than V.34 (28.8K),
such as V.17 (14.4K) and V.29/V.27ter(9600/4800), and has V.8 feature which supports the
procedure for selecting the optimal speed for verifying the line condition.
• TCF signal (in Phase B) is not used in V.34.
• The command (such as NSF/DIS) speed for the conventional procedure is 1200bps in
V.34.

NOTE1 Signal Names and Contents
CNG (Calling signal):
The signal for showing the communication function from the outgoing terminal is
sent continuously until ANSam arrives.
CNG is not recorded in Trace.
During Manual Send, 'CI' signal is sent as V.8 Calling signal
When Phase B is entered without ANSam being detected and DIS V.8 capability is
available (bit 6=1)', send CI from the outgoing side and return to the V.8 procedure in
Super G3 mode.
ANSam (Response signal):
