Using the DuSLIC chip set, ringing voltages up to 85 Vrms sinusoidal can be applied,
and trapezoidal ringing can be programmed as well.
For a detailed application diagram of internal balanced ringing see

2.5.6
The internal unbalanced ringing supported by SLIC-P can be used for ringing voltages
up to 50 Vrms. The SLICOFI-2 integrated ringing generator is used and the ringing signal
is applied to either the Tip or Ring line. Ringing signal generation is the same as
described above for balanced ringing. As only one line is used for ringing, technology
limits the ringing amplitude to about half the value of balanced ringing, to a maximum of
50 Vrms.

The maximum ringing voltage is:
V
When the called subscriber goes off-hook, a DC path is established from the Ring to the
Tip line. The DC current is recognized by the SLICOFI-2 because it monitors the IT pin.
An interrupt indicates ring trip if the line current exceeds the programmed threshold.
The same hardware can be used for integrated balanced or unbalanced ringing. The
balanced and unbalanced modes are configured by software. The maximum achievable
amplitudes depend on the values selected for
