Analog (Call Progress) Receive Path Mute.
00 = 0 dB.
01 = –6 dB.
10 = –12 dB.
11 = mute.
Analog (Call Progress) Transmit Path Mute.
00 = –20 dB.
01 = –26 dB.
10 = –32 dB.
11 = mute.
IIR Filter Enable.
0 = FIR filter enabled for transmit and receive filters. (See Figures 9–12 on page 13.)
1 = IIR filter enabled for transmit and receive filters. (See Figures 13–18 on page 14.)
Ring Detect Network Squelch.
This bit must be set, then cleared, following a polarity reversal detection. Used to quickly
recover the offset on the RNG1/2 pins after a polarity reversal.
0 = Normal.
1 = Squelch.
Ring Detector Full Wave Rectifier Enable.
When set, the ring detection circuitry provides full wave rectification. This will effect the
data stream presented on SDATA_IN during ring detection.
0 = Half Wave.
1 = Full Wave.
Read returns zero.
On-Hook Speed.
Sets speed of execution of an on-hook.
0 = Fast.
1 = Slow.
Billing Tone Detector Enable.
When set, a billing tone signal is detected on the line and off-hook is maintained through
the billing tone. If a billing tone is detected, the BTD bit of register 5Eh will be set to indi-
cate the event.
