G3 Send Mode

Figure A2.1.2 shows the G3 send picture signal route
In the G3 mode, the data transfer route from the scan unit up to the DRAM is the same as in the copy
mode described in (1).
The picture data for one-line is transferred from DRAM to CPU. The CPU performs the picture data
processing (encode) for this picture data (FILLER, fill bits are inserted etc.) and again stores into the
DRAM. The stored encoded data is output from DRAM to the MODEM under the control of CPU.
After modulation, the picture signal "S" is sent to the NCU board as the transmission data. The transmis-
sion data "S" goes through the amplifier and is sent to the telephone line L1 and L2 via the transformer
T1 as high speed signal.
