Dial Pulse Signal Transmission
Transmits 10pps/20pps dial pulse by a open/close action between Tip and Ring with Photo MOS relay which is controlled by DSP
GPIO port.
The make width, break width and inter digit width for 10pps/20pps can be set respectively.
When making DP[0-3] pin of DSP becomes Low level, and PC902A-D turns ON. When breaking, DP[0-3] of DSP becomes High
level, and PC902A-D turns OFF.

4.2.3.3.
Circuit For Line Acquisition
Making DP[0-3] pin of DSP becomes Low level, and PC902A-D turns ON and the line is acquired.
It is used in common as Dial Pulse transmitting circuit.
DC Loop Path:
1. Ring 
 D902  D906  D908  Q900(C-E)  Q904(C-E)  R920  D908  Tip
2. Tip 
 D908  R920  Q904(C-E)  Q900(C-E)  D908  D906  D902  Ring
After line acquisition, DC and/or AC characteristics (Dynamic Range and Distortion etc) are controlled by current controll function of
DC Loop Circuit.
Also it provides the SHUNT control function for the stabilization of line power depending on the destination. Turning on  PC903A-D
when transmitting pulse reduces the impedance at making, and stabilizes the line power.
4.2.3.4.
DTMF Signal Transmission
DTMF signal is generated by DTMF generator in the DSP device.
