Abstract

Για τηλεφωνικές τερματικές συσκευές, οι οποίες μέσω μονάδας αποκλεισμού δικτύου συνδέονται προς το υπηρεσιακό ολοκληρωμένο ψηφιακό πληροφοριακό δίκτυο (ISDN), προτείνεται μία διάταξη κυκλώματος (συνδεσμολογία), η οποία στην περίπτωση διακοπής της παροχής ενέργειας κατά τη λειτουργία ανάγκης καθοδηγεί (ρυθμίζει) την παροχή μέσω του τηλεφωνικού κέντρου κατά τέτοιο τρόπο, ώστε στην κατάσταση ηρεμίας η απολαβή αποδόσεως της τηλεφωνικής τερματικής συσκευής να ελαττώνεται στο ελάχιστο. Για το σκοπό αυτό η τάση για εσωτερικό καταναλωτή της τηλεφωνικής τερματικής συσκευής αποσυνδέεται και μόνο στην ενεργό κατάσταση, δηλαδή με ερχομένη ή απερχομένη κατάληψη, επανασυνδέεται.ωFor telephone terminals, which are connected to the service integrated digital information network (ISDN) through a network blocking unit, a circuit arrangement (connection) is proposed, which in the event of a power failure during emergency operation guides (regulates) the supply through of the telephone exchange in such a way that in the idle state the performance gain of the telephone terminal device is reduced to a minimum. For this purpose, the voltage for an internal consumer of the telephone terminal device is disconnected and only in the active state, i.e. with incoming or outgoing occupancy, is it reconnected.
