PROTECTORS FOR LUCENT TECHNOLOGIES L7581/2/3 LINE CARD ACCESS SWITCHES

The TISPL758LF3 is an integrated combination

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
