and goes into the amplifier IC101 pin (3). This circuit is used to
cancel the transmission return signal.
6.8.7. AUTO DISCONNECT CIRCUIT
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.
2. Circuit Operation
If the line is picked up, C104 is charged by the following path
shown below.
Tip (Ring) D118 R185 D115 R182 Q111 PC104
If a telephone connected in parallel goes into OFF-HOOK status,
the base of Q111 becomes low and PC104 turns OFF.
When the line is connected, Q111 and PC104 turn on, then pin
(152) of IC501 (ASIC) on the digital board becomes low. On the
other hand, When the line is disconnected, Q111 and PC104 turn
off, then the pin (152) of IC501 (ASIC) becomes high.
6.8.8. CPC (Calling Party Control) DETECTION CIRCUIT
1. Function
This circuit detects the signal (cuts the current ) output from the
converter when the other party finishes ICM recording and goes
into the ON-HOOK status.
TAD detects this signal and disconnects the line. When the TAD
is operating, pin (4) of PC107 becomes a low level.
While detecting the CPC signal, pin (4) of PC107 becomes a high
level. When the CPC signal is detected, the TAD operation stops
and the line is disconnected.
