FXS Configuration
Open Circuit DC Feed
Voltage Set the DC feed voltage of between Telephone interface TIP
and Ring in open circuit.
The range is 36 ~ 57V 48
BatterySwitching
Offset Voltage DC feed voltage between TIP and RING can be high, and
also can be low. You can change the threshold of battery
switching offset voltage by modifying this parameter. When
the voltage between TIP and RING is less than the
reference value ( Reference value = low v offset +
voltage due to chip’s resi 4 V ) and reach 2 ms, it
will switch from high voltage to low voltage; on the contrary,
if it arrives 2ms higher than the reference value, it will switch
from low voltage to high voltage.
The range is 3 ~ 12V
9
Current Limit Active
Mode Telephone interface (TIP and Ring) provide constant-current
feed to the load.
The range is 18 ~ 49mA 18
Ring Waveform Set Ring waveform of FXS port:
- Sinusoid
- Trapezoid Sinusoid
Ring Voltage ( Peak
Value) Set FXS ring voltage (peak value). The range is 1 ~ 155V 90
Ring Frequency Set the FXS ring frequency, whose range is: The range is 1
~ 3,400Hz 25
Ring Tone Cadency Set FXS ring on-off time sequence.
The format is :COn1/COff1,COn2/COff2, COn3/COff3,
COn4/COff4
For each period, utmost 4 tones are allowed. If ring tone
adopt 1s on, 4s off, the format will be : 1000/4000, 0/0, 0/0,
0/0 1000/4000,
0/0,0/0, 0/0
Hook flash time Set up FXS flash time limit. The range is 100 ~ 1000s
If On-Off time length is smaller than the set value, it will be
treated as flash signal.
300
FXS Port Impedance Set resistance of external equipment which connects to FXS
port. You can solve the voice quality problem which caused
by unmatched resistance through adjusting this parameter.
