6.9.6. SIDE TONE CIRCUIT (Change from original page 174)

1. Function

A sidetone is the returning of the TX signal to the RX signal. The sidetone circuit uses a bridge circuit to attenuate the

sidetone. Howling may occur if the attenuation of the sidetone is inadequate.

2. Circuit Operation

The TX signal is output to the circuit along the route from the IC10-1pin 

→

 C37 

→

 R58 

→

 R57 

→

 T1 

→

 TEL LINE. However,

if balance is lost in the bridge as shown below, a voltage occurs between the IC10-5 pin and 6 pin and a sidetone results.

Because the balance cannot be maintained completely at all frequencies in the audio range, some sidetones always occur.

6.9.8. AUTO DISCONNECT CIRCUIT (Addition)

   (1) Function

This circuit is used to detect that the telephone connected in parallel to the same line is OFF-hook while the unit picks up the

line. If this detection circuit is activated when TAM is being delivered, the delivery stops and the circuit is automatically

released.

   (2) Circuit Operation

If the line is picked up, C19 is charged by following the path shown below.

D6 (+) 

→

 Q3 

→

 R24 

→

 D12 

→

 C19

When the electric potential difference between the base and emitter of Q4 becomes less than about 0.3V, Q4 and Q6 and

PC5 turn off, then the IC5 pin 5 becomes a high level.

In this condition, if a telephone connected in parallel goes into OFF-hook status, the base of Q4 becomes low.

On the other hand, the emitter of Q4 goes down because the capacitor (C19) is charged. Q4 turns on when the electric

potential difference between the base and emitter of Q4 becomes more than 0.6 V while being charged.

When Q4 turns on, Q6 and PC5 also turn on, then the IC5 pin 5 becomes a low level.
