(1)With the LED as R light source, the image is scanned by t,he rontnct sensor, and
analogue image data sent to the SCNT hoard.
(2)The System controller IC (Internal UIIQ unit) converts analogue image data from the
(3)The system controller IC converts processed image data from srrinl data to parallel data,
(4)The MPU encodes raw data in the DRAM using a soft codec, and rewrites the encoded
(5)The MODEM IC modulates the coded image data.
(6)The modulated data arc then sent from the MODEM IC to the NCU board.
('7)The data are returned to the SCNT board and, from there, arc sent to the line for
