Transmission
1. Same processing as COPY items 1) - 3).
2. The data stored in RAM of IC1 is output from IC1 via routes (6)
and (10), and is stored in the system bus. / Via route (11), it is
stored in the communication buffer inside RAM (IC3).
3. While fetching data stored in the communication buffer
synchronous with the modem, the CPU inputs data to the modem
along route (12) and (14). / In the analog front end IC (IC5) it is
converted to serial analog data and forwarded over telephone
lines via the NCU Section.
Reception
1. The serial analog image data is received over telephone lines and
input to the analog front end IC (IC5) via the NCU section, where it
is demodulated to parallel digital data. The balance data is sent to
the modem. Then the CPU stores the data in the communication
buffer of RAM (IC3) along route (11) and (15).
2. The data stored in RAM (IC3) is decoded by the CPU via route
(12), and is stored in RAM by routes (13) and (5).
3. Same processing as COPY item 4).
