company.
Important:

- This unit is designed in accordance with the ETS (Euro-

pean Telecommunication Standard) and only supports 
the basic CLIP (Calling Line Identification Presentation) 
features.

- This unit will only display the caller’s telephone number 

and name. 

- This unit will not support future additional telephone ser-

vices.

- Depending on the service of the local telephone com-

pany, the date/time of the call or the callerís name may 
not be displayed.

- This unit is set to AOH service by default.

The following is an outline of each device IC on the digital board.

1. ASIC (IC106)

This custom IC is used for general FAX operations.

2. G/A (IC107)

(1) OPERATION PANEL I/F: Serial interface with Operation Panel.
(2) ANALOG GATE ARRAY I/F: Controls the ANALOG GATE ARRAY.
(3) MOTOR I/F: Controls the ENGINE Motor.
(4) FAN I/F: Controls FAN MOTOR and detect the rotation of FAN MOTOR.
(5) SENSOR I/F: Controls the LED and detect the sensor signal.
(6) I/O PORT: I/O Port Interface.

3. ROM (IC105)

This 8MB FLASH ROM contains all of the program instructions on the unit operations.

4. Synchronous Dynamic RAM (IC108)

This SDRAM is used for CPU work and receiving memory and page memory.

5. MODEM (IC111)

Performs the modulation and the demodulation for FAX communication.
Detects the CALLER ID signal.

6. Read Section

CIS image sensor to read transmitted documents.

7. LSU (Laser Scanning Unit)

Forms the images on the OPC drum by rotating polygon motor and reflecting the laser beam against polygon.

8. BBIC (Base Band IC): IC4

Handling all the audio, signal and data processing needed in a DECT base unit
Controlling the DECT specific physical layer and radio section (Burst Module Controller section)
ADPCM codec filter for speech encoding and speech decoding (DSP section)
Echo-cancellation and Echo-suppression (DSP section)
Any tones (tone, sidetone, ringing tone, etc.) generation (DSP section)
DTMF receiver (DSP section)
Clock Generation for RF Module
ADC, DAC, timer, and power control circuitry
All interfaces (ex: RF module, EEPROM, Analog Front End, etc.)

9. RF Module: IC2

PLL Oscillator
Detector
Compress/Expander
First/Second Mixer
Amplifier for transmission and reception

10. FLASH MEMORY: IC23

12. Analog Board

Composed of ITS circuit and NCU circuit.

13. Sensor Section

Composed of 4 switches and 5 sensors.

14. Power Supply Board Switching Section

Supplies +4V, +5V and +24V to the unit and controls the HEATER.

(1) CPU:

This model uses a Z80 equivalent CPU operating at 16MHz.
Many of the peripheral functions are handled by custom designed LSIs.
As a result, the CPU only needs to process the results.

(2) RTC:

Real time clock.

(3) DECODER:

Decords the address.

(4) ROM/RAM I/F:

Controls the SELECT signal of ROM or RAM and bank switching.

(5) LSU I/F:

Controls the polygon motor and outputs the VIDEO signal to LSU.

(6) I/O PORT:

I/O Port Interface.

(7) ANALOG UNIT:

Sends beep tones,etc.
Convert the analog signal to the digital signal.

(8) MOTOR I/F:

Controls the SCAN Motor.
