Abstract

In order to identify a zero following a leading zero of a trunk dialling telephone number and to release or bar the output of this telephone number, a device of a dialling evaluator (W) which is assigned to a dialling procedure (TwB) is disposed in a telephone set (1). <IMAGE>

Description

Einrichtung zur wahlweisen Freigabe oder Sperrung einerDevice for the optional release or blocking of a

Fernwahl -Rufnu'nmer.Long-distance dialing number.

Die Erfindung betrifft eine Einrichtung zur wahlweisen Freigabe oder Sperrung einer Fernwahl -Rufnummer.The invention relates to a device for optional release or Blocking a long-distance dialing number.

Bei einer Änderung einer Nebenstellenanlagen in eine Hauptsprechstelle wird dem Benutzer des Fernsprechapparates die Möglichkeit gegeben, Ferngespräche auch in das nicht bundesdeutsche Ausland zu führen.When changing a private branch exchange to a master station enables the telephone user to make long distance calls also to lead to non-Federal German foreign countries.

Der Nachteil besteht hierbei, daß eine Kostenerfassung aufgrunt der Gebührenfreiheit für Amtsanschlüsse nicht möglich ist.The disadvantage here is that cost accounting is based on the Free of charge for trunk lines is not possible.

Bekannt ist ein Sperrmitlauf in der Vermittlungsstelle, der die Durchwahl nach zwei aufeinanderfolgenden führenden Nullen einer Rufnummer verhindert.Known is a blocking follow-up in the exchange, the extension prevented after two consecutive leading zeros of a phone number.

In digitalen Vermittlungsanlagen ist die Software-Programmierung so ausgelegt, daß eine Überleitung der unerwünschten Ferngespräche nicht erfolgt und eine entsprechende Signalgabe beim Teilnehmer hervorgerufen wird.This is how software programming is in digital switching systems designed so that a transfer of unwanted long-distance calls does not take place and a corresponding signaling is caused by the participant.

Der Erfindung liegt die Aufgabe zugrunde eine Einrichtung in den Fernsprechapparat einzubauen, die eine Durchwahl ins Ausland für jeden Fernsprechteilnehmer seperat ermöglicht oder verhindert.The invention is based on the object of a device in the telephone set to build in a direct dialing number abroad for each subscriber separately enabled or prevented.

Die Lösung dieser Aufgabe besteht in den kennzeichnenden Maßnahmen des Anspruches 1.The solution to this problem consists in the characteristic measures of claim 1.

Bei einem herkömmlichen Fernsprechapparat mit Wählscheibe wird die Einrichtung einer Wahl auswertung die aus einer )IP-Schaltung besteht in den Fernsprechapparat eingebaut.In a conventional rotary telephone set, the Set up a election evaluation that consists of an) IP circuit in the telephone set built-in.

Beim Eintippen der Rufnummer wird die Rufnummer in gespeichert und verglichen.When entering the phone number, the phone number is saved in and compared.

Werden zwei Nullen am Anfang der Rufnummer eingetippt, so wird je Programmierung des Mikroprozessors die Rufnummer ausgegeben oder gesperrt, indem der Gabelumschalter mechanisch betätigt wird.If two zeros are typed at the beginning of the phone number, each will be Programming the microprocessor to output or block the phone number by the hook switch is operated mechanically.

In einem digitalen Fernsprechapparat wird der Tastenwahlcode vom pP ausgewertet. Hierdurch erfolgt entweder eine Ausgabe oder eine Sperrung der Rufnummer entsprechend der uP-Progrmmierung.In a digital telephone, the keypad code is obtained from the pP evaluated. This either outputs or blocks the phone number according to the UP programming.

Vorteilhafte weitere Ausgestaltungen der einzelnen Maßnahmen dieser Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous further refinements of the individual measures of this Invention are characterized in the subclaims.

Die Erfindung soll anhand des in den Zeichnungen dargestellten Ausführungsbeispieles näher erläutert werden.The invention is based on the embodiment shown in the drawings are explained in more detail.

Es zeigt: Fig.l einen digitalen Fernsprechapparat mit einer Wahlauswertung nach der Erfindung, Fig.2 die Anordnung der Wahl auswertung im System.It shows: Fig.l a digital telephone set with a selection evaluation according to the invention, Fig.2 the arrangement of the choice evaluation in the system.

Die Fig.l zeigt, daß die Einrichtung einer Wahlauswertung, die aus einer Mikroprozessor-Schaltung als zusätzlicher Baustein oder auch als Bestandteil der Steuerung (hierbei werden Funktionen der Steuerung St für die benötigten Funktionen der Wahlanwertung W mitbenutzt) besteht i digitalen Fernsprechapparat 1 eingebaut ist.The Fig.l shows that the establishment of an election evaluation, which from a microprocessor circuit as an additional component or as a component the controller (functions of the controller St for the required functions the ballot evaluation W also used) there is i built-in digital telephone set 1 is.

Die Fig. 2 zeigt, wie die Wahl auswertung W auf die im Fernsprechapparat 1 vorhandenen Einrichtungen ist. 1 rk t.Fig. 2 shows how the election evaluation W on the telephone set 1 existing facilities is. 1 rk t.

Die Wahleinrichtung W erkennt nach Eingabe eine auf eine führende Null eingegebene Null und sperrt die Ausgabe der Rufnummer.After input, the selection device W recognizes a leading one Zero entered zero and blocks the output of the call number.

Die Wahl der zweiten Null wird nicht signalisiert, sondern auf den Gabelumschalter geschaltet.The choice of the second zero is not signaled, but on the Hook switch switched.

Die Wahlauswertung W wirkt direkt auf das Wählorgang z.B.The election evaluation W acts directly on the selection process e.g.
