CLP30-200B1
4/11
Figure above shows the topology of a protected
analog subscriber line at the line card side.
I
A first stage based on CLP30-200B1 manages
the high power issued from the external surges.
When used in ringing mode, the CLP30-200B1
operates in voltage mode and provides a
symmetrical and bidirectional overvoltage
protection above 200 V on both TIP and RING
lines. When used in speech mode, the
CLP30-200B1 operates in current mode and
the activation current of the CLP30-200B1 is
adjusted by R
SENSE
.
I
A second stage which is the external voltage
reference device defines the firing threshold
voltage during the speech mode and also
assumes a residual power overvoltage
suppression. This stage can be either a fixed or
programmable device such as LCP1511D.
