[3] Circuit description of TEL/LIU PWB

1. TEL/LIU block operational description

1.1. Block diagram

1.2. Circuit description

The TEL/LIU PWB is composed of the following 6 blocks.

1. Speech circuit section

2. Dial transmission section

3. Speaker amplifier section

4. Ringer circuit section

5. CI detection circuit

6. Signal/DTMF transmission level & receiving level

1.3. Block description

1. Speech circuit section

• The receiver volume is an electronic volume type, this model is

switched in 3 steps.

2. Dial transmission section

• D.P. transmission: The CML relay is turned on and off for control in

the DP calling system. (Refer to the attached sheet.)

• DTMF transmission: It is formed in the modem, and is output.

3. Speaker amplifier section

• Ringer volume: It is controlled by the combination of the attenuator

value of the LINE DRIVER in the modem and the ringer sending
level sent from the modem.

• Speaker volume: It is controlled by the attenuator value of the LINE

DRIVER in the modem.

4. Ringer circuit section

• The ringer sound is formed in the tone of modem when CI signal is

detected. The amplifier circuit drives the speaker of the main body.
