Description
ATEN
0x16[4]
W
Active Termination Loop Enable
Enables or disables Active Termination Loop.
0 = Disable. (Default)
1 = Enable Active Termination Loop.
Note: normal operation requires this bit to be set to always enable a
termination circuit.
DCIV
0x13[7:6]
W
DC Current Voltage Characteristic Control
Hold state with ENDC and ENAC=1, at 20 mA DC loop current
measured at DCI. The Tip/Ring voltage assumes that there is a 5:1
attenuation of off-hook voltage at the DCI input pin.
DCIV1
DCIV0
Description
0
DC Loop On Voltage of 0.73 V
(5.60 V at Tip/Ring assuming a
5:1 step down of off-hook
voltage)
0
1
DC Loop On Voltage of 0.977 V
(6.75 V at Tip/Ring assuming a
5:1 step down of off-hook
voltage)
1
0
DC Loop On Voltage of 1.232 V
(7.65 V at Tip/Ring assuming a
5:1 step down of off-hook
voltage)
1
DC Loop On Voltage of 1.488 V
(9.35 V at Tip/Ring assuming a
5:1 step down of off-hook
voltage)
*Seize state with ENDC=1 and ENAC=0, 20 mA loop current.
DCIV =xxProvides a DC Loop “On” Voltage of 0.281V (3.9 V at Tip/Ring
assuming 5:1 step down of off-hook voltage)
ENAC
0x12[5]
WO
Enable AC Transconductance Circuit
0 = Shut Down AC Transconductance Circuit. Aux A/D input = Ring
Detect Buffer (RGP/RGN) / Line Voltage (DCI). Seize state for going
off hook. (Default)
1 = Enable AC Transconductance Circuit. Aux A/D input = Line Current
(DCS) / Line Voltage (DCI).
ENDC
0x12[6]
WO
Enable DC Transconductance Circuit
0 = Shut down Transconductance Circuit. (Default)
1 = Enable Transconductance Circuit.
ENFEL
0x12[2]
WO
Enable Front End Line-Side Circuit
0 = Power down Front End Line-Side circuits. (Default)
1 = Enable Front End blocks excluding DCGM, ACGM, shunt regulator.
