SPEAKER PHONE WITH SPEECH NETWORK

1. Receive Mode

2. Transmit Mode

3. Slow Idle Mode

4. Fast Idle Mode

Which of the above modes is to be determined depending on the following conditions:

1) Receive Mode

DETOTX1 < DETORX1, DETOTX2 < DETORX2, PDTX, X, PDRX : 1

2) Transmit Mode

DETOTX1 > DETORX1, DETOTX2 > DETORX2, PDTX : 1, PDRX : X

3) Slow Idle Mode

DETOTX1 > DETORX1, DETOTX2 > DETORX2, PDTX : 0, PDRX : X

DETOTX1 < DETORX1, DETOTX2 < DETORX2, PDTX : 0, PDRX : X

DETOTX1 < DETORX1, DETOTX2 > DETORX2, PDTX : 0, PDRX : X

DETOTX1 > DETORX1, DETOTX2 < DETORX2, PDTX : 0, PDRX : X

4) Fast Idle Mode

DETOTX1 > DETORX1, DETOTX2 < DETORX2, PDTX : 0, PDRX : 0

DETOTX1 < DETORX1, DETOTX2 > DETORX2, PDTX : Y, PDRX : Y

* "<" and ">" refer to voltage level : "X" refers to "It doesn't matter : "Y" is not zero

5. SWITCHING TIME

The switching time of the speaker phone is determined by the CT and RT of the outside elements.

1. Idle Mode → RX or TX Mode

ST = 4,000 X CT

2. TX or RX Mode → Fast Idle Mode

ST = 2,000 X CT

3. TX or RX Mode → Slow Idle Mode

ST = RT X CT

* CT, RT refer to the capacitor and resistor between Pin 34 and VCC.
