G3 Send Mode

Figure A2.2 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 IOGA4 (CPU). The IOGA4 (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 IOGA4 (CPU). After modulation, the

picture signal "S " is sent to the NCU board as the transmission data. The transmission data "S" goes through the

amplifier and is sent to the telephone line L1 and L2 via the transformer T1 as high speed signal.
