[FAX Tx]
1. An analog image data is output from CIS unit to IC503.
IC503 decode the analog data to digital data, and output to IC300.
Scanner I/F in IC300 process image data and store it in IC400/401
through SDRAM I/F.
2. CPU compress the data in IC400/401.
3. CPU transfer the data to MODEM
and output it to TEL LINE through DAA circuit.
MB221x, MB251x is excludes.

[FAX Rx]
1. FAX data is input from TEL LINE to MODEM in IC300
through DAA circuit.
And then store it in IC402 .
2. CPU decompress the data from IC402 to IC400/401.
3. Print I/F retrieve the data from IC400/401 and output it to LSU.
