' Deux RJ11, J1 et J2 connectent les 2 appareils. L'appel debute en ' decrochant J1. Les "Confort Tones" sont generes et le Talk Voltage (-28V) ' est present. Les tonalites sont: ' 1- Dial tone si on decroche J1 ' 2- Ligne occupee si J2 est decroche apres composition, "b" est affiche ' 3- Alert tone si ligne decrochee sur J1 et aucune action pour plus de 20s ' Un afficheur 7 segments affiche les tonalites composes de 0-9. ' L'affichage est allonge pour mieux voir les codes. ' La derniere tonalite est affichee pour 3 sec. ' Le * est affiche par A, le # par P. En attente, affiche n pour normal. ' Si on compose un numero de 7 ou 11 chiffres, le telephone sur J2 sonne. ' Si J2 decroche, J1 et J2 sont connectes ensemble. Un module ring ' generateur reproduit parfaitement le ring 20Hz, 90V peak sinusoidale. ' Un interrupteur "Ring" permet de faire sonner manuellement J1 sans ' compose un numero sur J1. Durant le ring, "r" est affiche. ' Une sortie jack 1/8 permet de monitorer L'audio sur la ligne a l'aide ' de haut-parleur amplifies.
