MUTE key operation
During OFF HOOK (or turn HF on) mode.
Press MUTE will flip MMUTE pin level.
In the end of dialing, the MMUTE pin will be driven to “high impedance” state.
Enter any key will auto-release “high impedance” state.
I.P.P. ( Illegal Parallel Phone )detect function
The system provide the I.P.P. function to protect illegal connect. I.P.P. means Illegal Parallel Phone detect.
I.P.P. functions depend on IPP pin , HKS and HF status. When in the ON-hook condition and HF turn off, the
IPP pin will be a input pin to detect the voltage lever, otherwise, the IPP pin will be a normally output pin use
for control handfree speaker. When I.P.P. function detect. IPP pin at “ low ” status ( In ON-hook and HF turn
off state), the system will turn on HF and send alarm signal to telephone line. In alarm duration DTMF pin
will continue sending “ # ”, “ 8 ”, “ # ”, “ 8 ”, “ # ”, “ 8 ” signal ( pulse mode sending “ 8 ”, “ 8 ”, “ 8 ” signal
). The DTMF signal will interface the illegal user until the illegal user hang up the phone and the IPP pin
detect “ high ” again or pressing HF key once, or OFF-hook action ( pick up handset ). The telephone circuit
design can allow the legal internal connect user.
