IPC: H04M19/02
Filed: 1988-02-11
Abstract: Die erfindungsgemäße Schaltungsanordnung sieht vor, 
daß die an jede Ader einer Anschlußleitung angeschlossene 
Induktivität aus je einer Drosselspule (DR₁; DR₂) besteht, die 
jeweils eine Sekundärwickung (S₁; S₂) aufweist. Diese 
Sekundärwicklungen sind jeweils mit zwei gegeneinander 
parallel geschalteten Dioden (D1a, D1b; D2a, D2b) überbrückt. Das 
Übersetzungsverhältnis der Wicklungen auf den 
Drosselspulen ist so gewählt, daß der induzierte Anteil 
der Rufspannung ausreicht, um die Dioden in den 
Durchlaßbereich zu steuern. Diese Abwärtstransformation 
bewirkt außerdem, daß im Gesprächszustand durch die 
Sprechströme nur eine sehr geringe Spannung an den 
Sekundärwicklungen entsteht, die nicht ausreicht, 
die Dioden in den Durchlaßbereich zu bringen.
