Abstract

Secondo una forma di realizzazione dell'invenzione, un metodo per stabilire toni di chiamata in corso per un sistema di commutazione avente un dispositivo di generazione di segnali generici, comprende le fasi di visualizzare almeno una forma su un visualizzatore e inserirla in campi delle definizioni di forma dei segnali generici di cadenza e particolari associati ad ogni tono di chiamata in corso per un piano di toni; memorizzare temporaneamente le definizioni in una memoria compilando le definizioni come segnali di controllo nel codice in oggetto; memorizzare il codice in oggetto in una memoria ad accesso casuale; e usare il codice in oggetto nell'elaborazione di una chiamata mediante un processore del sistema di commutazione per controllare l'invio di segnali particolari dal dispositivo di generazione di segnali generici con particolare livello di cadenza e di segnali a un abbonato o a un operatore.
