4.2.2.13. Caller ID Reception
The Caller ID signal from Central Office goes through the following circuits.
- Capacitors between TIP/RING and Caller ID Circuit for isolation
- Resistors between capacitors and ASIC for circuit protection or signal level control
- Diodes for protection against incomming surges.
- Capacitors between TIP/RING and Caller ID Circuit for isolation
- Resistors between capacitors and ASIC for circuit protection or signal level control
- Diodes for protection against incomming surges.
Then the Caller ID signal received by Caller ID ASIC(CIDA, IC308, IC409, IC508, IC509).
An ASIC(CIDA) supports four CO lines.

Power Supply Circuit
4.2.3.1.
Power Supply Circuit Operation
The circuit which generates output +3.3V, +5V with input +15V. It is configured with the circuit that reduces the voltage from
+15V to +3.3V by IC801, Q801, D801 and L801 switching power supply, and with the circuit that reduces the voltage from +15V
to +5V by IC802, Q802, D802 and L802 switching power supply.
There are two protection lines. One is F1 for +15V short protection, the other is the over voltage protection which detects
+15V to +3.3V by IC801, Q801, D801 and L801 switching power supply, and with the circuit that reduces the voltage from +15V
to +5V by IC802, Q802, D802 and L802 switching power supply.
There are two protection lines. One is F1 for +15V short protection, the other is the over voltage protection which detects
+3.3V/+5V voltage rise and make FET Q15 OFF.
