1.INTRODUCTION
The aim of this section is to show the behavior of
our new telecom line protection device.
Figure 1
is a simplified block diagram of a
subscriber line protection that is mainly used so
far.
This shows two different things :
A “primary protection” located on the Main Dis-
tribution Frame (MDF) eliminates coarsely the
high energy environmental disturbances (light-
ning transients and AC power mains distur-
bances) for which the ITU-T-K20 requires a 4kV
10/700
μ
s test. This can be assumed either by
gas-tubes or silicon protection such as the
TLPxxM.
A “secondary protection” located on the line
card eliminates finely the remaining transients
that have not been totally suppressed by the
first stage. The ITU-T-K20 requires a 1 kV
10/700
μ
s test. At this stage, the protection is
managed by the CLP30-200B1.

2.1 Evolution of the SLIC protection
Over the years, the performances of the SLICs
considerably increased and therefore the need of
the protection has also evolved.
The CLP30-200B1 is especially designed for the
protection of this new generation of SLIC. For this,
it is based on both overvoltage and overcurrent
protection modes.
The
figure 2
summarises the performance of the
CLP30-200B1 which basically holds the SLIC
inside its correct voltage and current values.
