Full Scale.
0 = Default.
1 = Transmit/receive full scale = +3.2 dBm.
This bit changes the full scale of the ADC and DAC from –1 dBm min to +3.2 dBm min. When this
bit is set, R2 must be changed from 402 Ω to 243 Ω. This mode can be useful for certain voice
applications and should only be used in the FCC/600 Ω AC Termination mode.
DTMF Dialing Mode.
This bit should be set during DTMF dialing in CTR21 mode if LCS[3:0] < 6 or
LVCS[4:0] < 12 decimal.
0 = Normal operation.
1 = Increase headroom for DTMF dialing.
Force Japan DC Termination Mode.
0 = Normal Gain
1 = When the DCT[1:0] bits are set to 10b (FCC mode), setting this bit will force the Japan dc ter-
mination mode while allowing for a transmit level of –1 dBm. See "4.13. DTMF Dialing" on page
19.
Line Voltage Adjust.
When set, this bit will adjust the TIP-RING line voltage. Lowering this voltage will improve margin
in low-voltage countries. Raising this voltage may improve large signal distortion performance.
0 = Normal operation.
1 = Lower DCT voltage.
