Detector output. Active low when indicating
loop or ring-trip detection, active high when
indicating ground key detection.
+5 V power supply.
Programmable loop detector threshold. The
loop detection threshold is programmed by a
resistor connected from this pin to AGND.
Programmable overhead voltage. If pin is left
open: The overhead voltage is internally set
to min 1.0 V in off- and on-hook. If a resistor
is connected between this pin and AGND:
The overhead voltage can be set to higher
values.
Programmable line current, the constant
current part of the DC feed characteristic is
programmed by a resistor connected from
this pin to AGND.
A reference, 49.9 k , resistor should be
connected from this pin to AGND.
Receive summing node. 200 times the AC
current flowing into this pin equals the
metallic (transversal) AC current flowing from
RINGX to TIPX. Programming networks for
two-wire impedance and receive gain
connect to the receive node. A resistor should
be connected from this pin to AGND.
Analog ground, should be tied together with
BGND.
