Test loop selection
Caller ID path control
Disable high-pass in transmit direction
Disable high-pass in receive direction
2nd tone of caller ID not detected
ALB_CIF: Cap. interface loop of the signal from the input circuit
(CAP_B11/12 is connected to the output drivers (CAP_A11/12,
CAP_C11/12)
ALB-CID: Caller ID loop; the output signal from the caller ID
comparator is connected to the output drivers of the capacitor
interface (CAP_A11/12, CAP_C11/12);
DLB-2M: Loop via HW filters;
DLB-128k: Loop inside DSP;
DLB-64k: Loop inside DSP;
DLB-PCM: Loop via PCM interface; the received data is sent back
in the next frame;
Test loops via impedance path selected
Test loops via receive path selected
Caller ID interface enabled during ringing mode
Caller ID interface will be selected by the Call_pon bit in CR2
Transmit high-pass enabled
Transmit high-pass disabled
Receive high-pass enabled
