Abstract
Innerhalb derartiger Fernmeldeanlagen sind Ein-Ausgabeeinrichtungen (IOP1, m) und/oder allen Einrichtungen zur Ansteuerung von Koppelpunkten zur Durchschaltung des Sprechwegekoppelnetzwerkes (CNS) jeweils eigene Rückstelleinheiten (R) zugeordnet, so daß die Zentralsteuereinrichtung (CP) den Fehlerzustand der Ein-Ausgabeeinrichtungen (IOP1, m) und/oder der Einrichtungen (LTU1, n) zur Ansteuerung von Koppelpunkten zur Durchschaltung des Sprechwegekoppelnetzwerkes (CNS) im Hinblick auf die Freischaltung steuern kann. Derartige Schaltungsanordnungen werden für zentralgesteuerte Fernmeldeanlagen, insbesondere für Fernsprechnebenstellenanlagen, eingesetzt.Within such telecommunication systems, input / output devices (IOP1, m) and / or all devices for controlling crosspoints for switching through the speech path coupling network (CNS) are each assigned their own reset units (R) so that the central control device (CP) detects the error status of the input / output devices ( IOP1, m) and / or the devices (LTU1, n) for controlling crosspoints for switching through the speech path coupling network (CNS) with regard to activation. Such circuit arrangements are used for centrally controlled telecommunications systems, in particular for telephone private branch exchanges.

IEC ansteuerbar sind. Durch die Zentraisteuereinrichtung CP können mittels der Schaltmittel zur Überwachung der Aktivmeldung die Ein-Ausgabeeinrichtungen /OPl, m und/oder die Einrichtungen LTUi, η zur Ansteuerung von Koppelpunkten zur Durchschaltung des Sprechwegekoppelnetzwerkes angesteuert werden, die jeweils mittels des adressierbaren Rückstellbefehls die Ein-AusgabeeinrichUj'pgen lOP\,m und/oder die Ein- 6<> richtungen LTU1, η zur Ansteuerung von Koppelpunkten zur Durchschaltung fies Sprechwegekoppelnetzwerkes CWSfreischalten.The input / output devices IOP \, m and all devices LTU 1, η for controlling the crosspoints for switching through the speech path coupling network CNS are shown as decentralized devices. At the devices LTUi, η , for example, subscriber circuits TA 1, η are connected, and the devices for controlling crosspoints for switching through the speech path coupling network CNS as well as the input / output devices \ OP \, m have the reset units R , which, depending on the control program can be controlled by the central control device CP via the first or via the further data transmission line bundle HDLC or IEC . The central control device CP can be used to control the input / output devices / OPl, m and / or the devices LTUi, η for controlling crosspoints for switching through the speech path coupling network by means of the switching means for monitoring the active message, which in each case use the addressable reset command to control the input / output devicesUj ' pgen lOP \, m and / or the devices LTU 1, η for controlling crosspoints for switching through the speech path coupling network CWS.
