Abstract
En anordning for å tilføre abonnentlinjene (10) i en offentlig sentral redusert linjestrøm ved forekomst av en kraftsvikt, når temperaturen inne i den offentlige sentral eller temperaturen til individuelle komponenter, montert på kretskort på hvilke linjegrensesnittkretsene er til stede, overskrider en forutbestemt referanseverdi, når lengden av en abonnents linje er mindre enn en linjelengde-referanseverdi, eller når samtaletiden på en abonnentlinje overskrider en samtaletid- referanseverdi. Alle abonnentlinjer eller bare individuelle abonnentlinjer blir matet med redusert linjestrøm for en begrenset tid.
