Abstract

Le circuit joncteur de ligne d'abonné pour centraux PENTACONTA se différencie des joncteurs classiques à deux relais en ce que le relais d'appel qu'il comporte a un seul enroulement et en ce que chaque enroulement de relais coopère avec une diode pour assurer au circuit un fonctionnement autonome. Les diodes sont de type usuel; les relais sont des relais miniature existant dans le commerce. Le circuit procure un gain de place important. Applicable aux centraux télephoniques classiques du type PENTACONTA.
