P R O D U C T
The TISPL758LF3 is an integrated combination
of
protector and an asymmetrical bidirectional
overvoltage protector. It is designed to limit the
peak voltages on the line terminals of the Lucent
Technologies
Access Switches). An LCAS may also be
referred to as a Solid State Relay, SSR, i.e. a
replacement
mechanical relay.
The TISPL758LF3D voltages are chosen to give
adequate
conditions.

condition is low level power cross when the
LCAS switches are closed. Under this condition,
the TISPL758LF3D limits the voltage and
corresponding LCAS dissipation until the LCAS
thermal trip operates and opens the switches.
Under open-circuit ringing conditions, the line
ring (R) conductor will have high peak voltages.
For battery backed ringing, the ring conductor
will have a larger peak negative voltage than
positive i.e. the peak voltages are asymmetric.
An overvoltage protector with a similar voltage
asymmetry will give the most effective protection.
On a connected line, the tip (T) conductor will
have much smaller voltage levels than the open-
circuit ring conductor values. Here a symmetrical
voltage protector gives adequate protection.
Overvoltages are normally caused by a.c. power
system or lightning flash disturbances which are
induced or conducted on to the telephone line.
These overvoltages are initially clipped by
protector breakdown clamping until the voltage
rises to the breakover level, which causes the
Terminals T, R and G correspond to the
alternative line designators of A, B and C
