Application requirements differ with regard to ringing amplitudes, power requirements,
loop length and loads. The DuSLIC options include three different SLICs to select the
most appropriate ringing methods (see

SLIC-S allows balanced ringing up to 45 Vrms and is dedicated for short loop or PBX
applications.
For SLIC-S2 only external ringing is provided.
SLIC-E/-E2 allows balanced ringing up to 85 Vrms and can therefore be used in systems
with higher loop impedance.
