Abstract
Innretning for anvendelse ved feilsøking i et telekommunikasjonssystem som omfatter en første og en andre del innbyrdes forbundet med en linje (4, 5), omfattende: (a) en første krets som kan serie- kobles med linjen og omfatter en første kondensator og en første komponent, slik at en vekselstrøm kan føres via linjen og kondensatoren og en likestrøm kan føres via linjen og den første komponent i minst en retning tilordnet en terskel- spenning, og (b) en andre krets som kan kobles i parallell over linjen og omfatter en andre komponent med en terskelspenning større enn 48 V og/eller innrettet for å kunne føre likestrøm bare i en retning.Device for use in troubleshooting a telecommunication system comprising a first and a second portion interconnected with a line (4, 5), comprising: (a) a first circuit which can be series connected to the line and comprises a first capacitor and a first a component such that an alternating current can be passed through the line and the capacitor and a direct current can be passed through the line and the first component in at least one direction assigned a threshold voltage, and (b) a second circuit which can be connected in parallel across the line and comprises a second component having a threshold voltage greater than 48 V and / or arranged to conduct direct current only in one direction.
