Abstract

A PROTECTIVE CIRCUIT (10) FOR A TELECOMMUNICATIONS SYSTEM TO PROTECT EQUIPMENT SUCH AS FACSIMILE MACHINES. THE CIRCUIT INCLUDES A PAIR OF SIGNAL LINES (12, 13) TO BE ATTACHED TO THE TELECOMMUNICATIONS SYSTEM. THE SIGNAL LINES (12, 13) ARE CONNECTED TO AN EARTH LINE (15) BY MEANS OF A GAS FILLED PROTECTOR (14). A PAIR OF VARISTORS (17) ARE ARRANGED SO THAT EACH SIGNAL LINE (12, 13) IS CONNECTED TO THE EARTH LINE (18) VIA ONE OF THE VARISTORS (17), WHILE LOCATED IN EACH SIGNAL LINE (12, 13), BETWEEN THE GAS FILLED PROTECTOR (14) AND THE VARISTOR (17), IS A RESISTOR (19). THE GAS FILLED PROTECTORS (14) ACT TO LIMIT THE VOLTAGE APPLIED TO THE EQUIPMENT SHOULD THE SIGNAL LINES (12, 13) BE SUBJECTED TO A LIGHTNING STRIKE.
