7.7.2. MODEM CIRCUIT OPERATION
The modem (IC505) has all the hardware satisfying the ITU-T standards mentioned previously.
When the ASIC IC501 (61) is brought to a low level, the modem (IC505) is chip-selected and the
resistors inside IC are selected by the select signals from ASIC (IC501) ADR0-ADR4(pin 83~87).
Commands are written through the data bus, and all processing is controlled by the ASIC
(IC501) according to ITU-T procedures. Here, the INT signal dispatched from IRQ (pin 60 of
IC505) to the ASIC (IC501) implements post processing.
This modem (IC505) has an automatic application equalizer. With training signal 1 or 2 at the
time of G3 reception, it can automatically establish the optimum equalizer. The modem (IC505)
clock is supplied by pin 55 of ASIC (IC501).
1. Facsimile Transmission/DTMF Line Send
The digital image data on the data bus is modulated in the modem
(IC505), and sent from pin 44 via amplifier IC501(2 1), Analog SW
