Communication Mode

(1)

Priority

• This system has two communication modes: ECM and G3. Communication will be estab-
lished with an appropriate mode determined by the capability of the remote terminal. The
priority of the communication modes is as follows:
Communication
Priority
mode
1st ECM
2nd G3
Note:
G4/UHS/G2/MF modes are unavailable to the system.
(2)

Communication modes of ECM/G3

An optimal mode will be selected according to the capabilities of both terminals:
V.34/ECM
TX V.17/ECM
(Sender) V.17/G3
V.29/ECM
V.29/G3
V.34: 33600 ~ 240 bps starting mode
V.17:14000 bps starting mode
V.29: 9600 bps starting mode
<<2>> Encoding Method
There are 4 encoding methods available to this system: JBIG, MMR, MR, MH. An optimal
method will be selected according to the capabilities and image quality of both terminals.
