Abstract
En anordning (1) for beskyttelse av telekommunikasjonsutstyr mot et unormalt transi-entspenningssignal mottatt over telekommunikasjonslinje (2, 3), der anordningen inne-holder komponenter (16, 18,20,22,26) for selektiv undertrykkelse av transient-spenningssignal fra andre normale kommunikasjonssignaler. Kretselementene som sørger for undertrykkelse (t6,18,20, 22, 26) reagerer på frekvens snarere enn spen-ningen på transientspenningesignalet. Kretselementer som sørger for overspennings-bekyttelse (12, 14) kan også tilveiebringes for å undertrykke transientsignaler og konti-nuerlige overspenningssignaler som opptrer på telekommunikasjonslinjen (2, 3).
