Abstract
Cette sonnerie de poste téléphonique est capable de recevoir des signaux d'appel provenant aussi bien de centraux électromécaniques classiques que de centraux électroniques. Il est prévu des moyens FI, RI pour détecter ces signaux d'appel, pour les isoler des bruits par filtration et pour exciter, sur la base de cette détection, une première alimentation stabilisée Al propre à exciter un circuit local GL propre à produire un bruit de sonnerie. Afin d'alimenter en permanence les moyens détecteurs-identificateurs FI, RI, il est prévu une seconde alimentation stabilisée A2, capable de prélever la tension de courant continue présente sur la boucle d'abonné et de produire à sa sortie une tension stabilisée de courant continu.
