Abstract

Inventia se refera la un interfon procesor destinat retelelor cu abonatii pe linie comuna si ranguri diferite de prioritate, care utilizeaza o linie comuna pentru toate posturile, pe care se transmite semnalul audio reprezentând mesajele, cât si, pe un alt conductor, o tensiune de semnalizare care nominalizeaza atât postul chemator printr-un semnal de recunoastere, cât si postul chemat printr-un semnal de apel. Fiecare post are o prioritate în retea; el realizeaza o supraveghere permanenta a liniei de semnalizare si intra în functionare audio fie atunci când este chemat de un alt post, fie atunci când cheama el un alt post si linia este libera sau sunt în convorbire cu prioritate mai mica.
