For SLIC-P two selections are possible.

with SLIC-P SEL-SLIC[1:0] = 10 should be chosen. In this case
internal unbalanced ringing in not needed and therefore there is no
need to switch the C3 pin of the SLIC-P to 'High'. The C3 pin of the
SLIC-P has be connected to GND and the IO2 pin of the SLICOFI-2
is free programmable for the user.
There is no need for a high battery voltage for ringing either. This
mode uses VBATR for the on-hook voltage (e.g. – 48 V) in Power
Down Resistive (PDR) mode and the other battery supply voltages
(e.g. VBATH = – 24 V and VBATL = – 18 V) can be used for the
off-hook state. This will help to save power because the lowest
possible battery voltage can be selected (see DuSLIC Voltage and
Power Application Note).
