Figure 3 above showsthe topology of a protected
analog subscriber line at the exchange side. The
CLP200M is connected to the ring relay via two
balancedRp resistors, and to the SubscriberLine
Interface Circuit. A second device is located near
theSLIC : it can be either a LCP1511Dor a THDT
series.
These two devices are complementary and their
functionsare explainedbelow :
The first stage based on CLP200M manages
the high power issued from the external
surges. When used in ringing mode, the
CLP200M operates in voltage mode and pro-
vides
a
symmetrical
overvoltage protection at +/-215 V on both TIP
and RING lines. When used in speech mode,
the CLP200M operates in current mode and
the activation current of the CLP200M is ad-
justed by R
SENSE
.
and
bidirectional
The second stage is the external voltage refer-
ence device which defines the firing threshold
voltage during the speech mode and also as-
sumes
a
residual
suppression.This protectionstagecan be either
a fixed or programmable breakover device.The
THDTxxfamily acts as a fixedbreakover device
whilethe LCP1511Doperates as a programma-
bleprotection.
Thanks to this topology, the surge current in the
line is reduced after the CLP200M. Because the
remainingsurgeenergyis low,thepowerratingsof
Rp,theringrelaycontactsandtheexternalvoltage
referencecircuit maybe downsized.This resultsin
a significant costreduction.
