Function
The RINGX pin connects to the ring lead of
the two-wire interface via over voltage
protection components and ring relay (and
optional test relay).
Battery ground, should be tied together with
AGND.
The TIPX pin connects to the tip lead of the
two-wire interface via over voltage protection
components and ring relay (and optional test
relay).
Battery supply voltage. Negative with respect
to GND.
An optional second (2) Battery Voltage
connects to this pin via an external diode.
Programmable saturation guard. The
resistive part of the DC feed characteristics is
programmed by a resistor connected from
this pin to
Connection for low pass filter capacitor,
Other end of
Input to the ring trip comparator. With DR
more positive than DT the detector output,
DET, is at logic level low, indicating off-hook
condition. The external ring trip network
connects to this input.

C1, C2, C3 are digital inputs (positive logic,
internal pull-up), which control the SLIC
operating states. Refer to
