Battery Selection
Battery selection is a technique, for a two battery supply
system, where the SLIC automatically diverts the loop
current to the most appropriate supply for a given loop
length. This results in significant power savings and lowers
the total power consumption on short loops. This technique
is particularly useful if most of the lines are short, and the on
hook condition requires a -48V battery. In Figure 26, it can
be seen that for long loops the majority of the current comes
from the high battery supply (V
BH
) and for short loops from
the low battery supply (V
BL
).
