Figure 4 shows a typical powering arrangement for a multi-supply rail SLIC. V BATL is a lower (smaller) voltage supply than V BATH . With supply
switch S1 in the position shown, the line driver amplifiers are powered between 0 V and V BATL . This mode minimizes the power consumption
for short loop transmission. For long loops and to generate ringing, the driver voltage is increased by operating S1 to connect V BATH . These
conditions are shown in Figure 5.
Conventional ringing is typically unbalanced ground or battery backed. To minimize the supply voltage required, most multi-rail SLICs use
balanced ringing as shown in Figure 5. The ringing has d.c., V
has a peak value, V

10 V. This makes a total, V
In some cases a trapezoidal a.c. ring signal is used. This would have a peak to r.m.s ratio (crest factor) of about 1.25, increasing the r.m.s. a.c.
ring level by 13 %. The d.c. ring voltage may be lowered for short loop applications.
