Abstract

The invention relates to a method for a microprocessor-controlled PABX system, in articular an intercom system with external terminals. The terminals in the intercom system operate with digital control signals and the external terminals with analog control signals. A call diversion facility is provided from the internal terminals. If this call diversion is forgotten, a facility is to be provided from an authorised external terminal for incoming calls to diverted there without a call of this type being lost when an external terminal is not busy and an internal terminal is busy. This is implemented in that a flag can be inserted by the external terminal in the central system memory by means of which the call is routed in parallel to the external terminal and to the corresponding internal terminal. This flag can be deleted again by the external terminal. The analog-digital conversion and vice versa are performed by an adaptation device. The method can be used essentially in extensions with mixed control-signal and dialling methods.

Description

Hieraus ergibt sich der Vorteil, daß entsprechend einer über das Betriebsfeld der zentralen Steuerung in den Kundendatenspeicher eingegebene Berechtigung und Zuordnung parallel zur Reihenanlagenstation von einer Außenstation aus eingeleitet der Ruf zur Reihenanlagenstation auch an der Außenstation ankommt und daß bei Vergessen der Abschaltung dieser Rufparallelschaltung bei unbesetzter Außenstation trotzdem eine Anrufentgegennahme an der Reihenanlagenstation erfolgen kann. This has the advantage that a corresponding one over the Authorization entered in the customer data memory operating field of the central controller and assignment initiated parallel to the row system station from an outstation the call to Row system station also arrives at the outdoor station and that if you forget to switch off this call parallel connection when unoccupied Outside station, calls can still be received at the row system station can.

Eine vorteilhafte Weiterbildung des erfindungsgemäßen Verfahrens besteht darin, daß an der im Kundendatenspeicher dem ersten Kennzeichen zugeordneten Reihenanlagenstation ein in der Wählart der Reihenanlage gehaltenes das Merkzeichen im Systemspeicher - sofern eingegeben - löschendes Kennzeichen eingebbar ist. An advantageous further development of the method according to the invention consists in that assigned to the first identifier in the customer data memory Line system station a flag held in the dial system of the line system In the system memory - if entered - the deleting identifier can be entered.

Hieraus ergibt sich der Vorteil, daß die Rufparallelschaltung bei Vergessen der Abschaltung an der Außenstation nachträglich von der Reihenanlagenstation aus abgeschaltet werden kann. This has the advantage that the call parallel connection with Forgetting to switch off the outdoor station afterwards from the row system station can be switched off.

Das erfindungsgemäße Verfahren wird nachstehend anhand einer Figur erläutert. Dabei sind in der Figur nur die erfindungswesentlichen Anlageeinheiten skizziert. The method according to the invention is illustrated below with reference to a figure explained. Only the system units that are essential to the invention are shown in the figure outlined.

Diese Einheiten bestehen aus der zentralen Steuerung ZSTmit dem Kundendatenspeicher KDS, dem Systemspeicher SS, dem Betriebsfeld BFund den Anpassungseinheiten AE 1 bis AEX, aus den Reihenanlagestationen RS1 bis RSX, aus den Außenstationen AS 1 bis ASX und aus den weiterführenden Verbindungsleitungen (Amtsle: ungen) AL 1 bis ALX Bei Reihenanlagen der vorgenannten Art ist jeder Funktionstaste, wie Anschalten einer Amtsleitung, Direktruf einer anderen Reihenanlagestation, Rückruf, Betätigen einer Taste des Tastwahlblockes einschließlich Betätigen des Gabelumschalters usw. ein bestimmter digitaler Code zugeordnet, der über das Signaladernpaar zwischen Station (z. B. RS 1) und zentraler Steuerung (ZST) zur zentralen Steuerung (ZST) übertragen und von einem Signalprozessor aufgenommen und zur Weiterverarbeitung an einen Vermittlungsprozessor weitergegeben wird. Dabei ist ein Kundendatenspeicher (KDS) vorgesehen, der jeweils bei Einleiten eines Teilnehmerwunsches abgefragt wird, wobei auf eine vorliegende Berechtigung des Teilnehmers geprüft wird. Die einzelnen Berechtigungen können über das der zentralen Steuerung (ZST) zugeordnete Betriebsfeld (BF) in bekannter Weise eingegeben bzw. geändert werden. Die Durchschaltung der Sprechverbindung zwischen zwei Teilnehmerstationen wird über zwei Sprechadern realisiert. Soll eine Verbindung von einer Reihenanlagestation (z B. RS 1) über eine Amtsleitung (z. B. AL 1) hergestellt werden, dann erfolgt die Umsetzung der in Codeform von der Reihenanlagestation abgegebene Wahlinformation in der zentralen Steuerung ZST und zwar in die Wahlart, die von der weiterführenden Anlage verarbeitet werden kann (z. B.These units consist of the central control ZST with the customer data memory KDS, the system memory SS, the operating field BF and the adaptation units AE 1 to AEX, from the serial system stations RS1 to RSX, from the outstations AS 1 to ASX and from the connecting lines (Amtsle: ungen) AL 1 to ALX In series systems of the aforementioned type, each function key is like switching on an exchange line, direct call to another key exchange station, callback, press a key on the keypad including actuation of the hook switch, etc. a specific digital code is assigned that is transmitted via the signal wire pair between Station (e.g. RS 1) and central control (ZST) for central control (ZST) transmitted and recorded by a signal processor and for further processing is passed on to a call processor. There is a customer data store (KDS) provided, which is queried each time a participant request is initiated, whereby a present authorization of the participant is checked. The single ones Authorizations can be obtained via the operating field assigned to the central control system (ZST) (BF) can be entered or changed in a known manner. The switching of the Speech connection between two subscriber stations is implemented via two speech wires. Should a connection from a key system station (e.g. RS 1) via an exchange line (e.g. AL 1) are then implemented in code form of dialing information given to the row system station in the central control ZST namely in the type of choice that can be processed by the secondary system (e.g.

Impulswahl, MFV-Wahl usw.).Pulse dialing, DTMF dialing, etc.).

An jeder Reihenanlagestation befinden sich außerdem Schalter, mit denen die Station für ankommende Anrufe (Amtsanrufe) freigeschaltet werden kann, wobei diese Anrufe zu einer anderen im Kundendatenspeicher hierfür einprogrammierten Station weitergeleitet werden. There are also switches, with, at each row system station which the station can be activated for incoming calls (outside calls), these programmed calls to another in the customer data store for this purpose Station to be forwarded.

An eine vorgenannte Reihenanlage können weiterhin Außenstationen angeschlossen werden (AS 1 bis ASX), die aus üblichen Fernsprechapparaten mit z. B. Impulswahl bestehen und wobei je ein Adernpaar zur Reihennebenstellenanlage führt. Die Schnittstelle zwischen der zentralen Steuerung ZSTder Reihennebenstellenanlage und einer Außenstation bildet eine Anpassungseinrichtung (AE1 bis AEXl die mit einem eigenen Mikroprozessor ausgerüstet ist. Die von der Reihenanlage kommenden und für die Außenstation (z. B. ASt) bestimmten Daten werden in der Anpassungseinrichtung (z. B. AE1) z B. in Rufwechselströme oder Hörtöne umgesetzt und zur Außenstation (AS 1) gesendet. In Gegenrichtung nimmt die Anpassungseinrichtung (AE 1) die Signale der Außenstation (ASt) (Signale des Gabelumschalters, des Wahlvorganges und der Erdtaste) auf und wandelt sie in für die zentrale Steuerung verständliche Daten um. Geht man davon aus, daß die Außenstation AS 1 eine Nachtstelle sei, zu der zu bestimmten Zeiten alle für die Reihenanlagestation oder auch für die gesamte Reihenanlage ankommenden Anrufe umgeleitet werden sollen, dann werden z. B. an der Reihenanlagestation RS 1 (in diesem Falle übergeordnete Station) der oder die Schalter so umgelegt, daß eine Anrufumleitung zur Außenstation AS 1 erfolgt. Dabei ist die Zuordnung des jeweiligen Umleitschalters zur jeweiligen Außenstation im Kundendatenspeicher KDSeinprogrammiert. Outstations can still be connected to an above-mentioned series system be connected (AS 1 to ASX), which consist of conventional telephones with z. B. impulse dialing and with one pair of wires each leading to the series private branch exchange. The interface between the central control ZST of the series private branch exchange and an outstation forms an adaptation device (AE1 to AEXl with a own microprocessor is equipped. The coming from the series system and for the external station (e.g. ASt) certain data are stored in the adaptation device (e.g. AE1) e.g. converted into ringing alternating currents or audible tones and to the front-door station (AS 1) sent. The adaptation device (AE 1) receives the signals in the opposite direction the front-door station (ASt) (signals from the hook switch, the selection process and the Earth button) and converts it into data that the central controller can understand around. If one assumes that the outstation AS 1 is a night station to which to certain times all for the series system station or for the entire series system incoming calls are to be diverted, then z. B. at the row system station RS 1 (in this case the higher-level station) the switch (s) switched so that that a call forwarding to the front-door station AS 1 takes place. The assignment of the programmed into the customer data memory CD.

Wird diese Betätigung des Schalters vergessen, dann kann erfindungsgemäß von der Außenstation AS 1 aus dieses Versäumnis durch Wahl eines bestimmten Kennzeichens wettgemacht werden. Das z. B. in Impulsform abgegebene Kennzeichen (erstes Kennzeichen) wird durch die Anpassungseinrichtung A E 1 in eine für die zentrale Steuerung ZST lesbare Form (Digitales Datenformat) umgewandelt und an die erkennenden und verarbeitenden Einrichtungen der zentralen Steuerung weitergegeben. Zunächst wird im Kundendatenspeicher KDS geprüft, ob die Außenstation AS 1 zur Durchgabe dieses Kennzeichens berechtigt ist. Bei positivem Prüfungsergebnis wird entsprechend der Information ein »Merker« im Systemspeicher SS gesetzt, der bei für die Station RS 1 (oder für die gesamte Reihenanlage) ankommenden Anrufen den Ruf zusätzlich zur Außenstation AS1 weiterleitet. Damit kann bei nicht besetzter Reihenanlage der Anruf an der Außenstation entgegengenommen werden. If this actuation of the switch is forgotten, then according to the invention from the outstation AS 1 this omission by selecting a specific identifier be made up for. The Z. B. Identifiers issued in pulse form (first identifier) is converted into one for the central control ZST by the adapter A E 1 readable form (digital data format) converted and sent to the recognizing and processing Facilities of the central control passed on. First is in the customer data store KDS checked whether the outstation AS 1 authorizes the transmission of this identifier is. If the test result is positive, a "marker" is displayed according to the information is set in the system memory SS, which is available for the station RS 1 (or for the entire Series system) also forwards incoming calls to the front-door station AS1. This means that the call can be accepted at the front-door station when the row system is not occupied will.

Durch die Abgabe eines zweiten Kennzeichens (zweites Kennzeichen) an der Außenstation AS 1 kann der »Merker« in gleicher Weise im Systemspeicher SS der zentralen Steuerung ZST wieder gelöscht werden. By submitting a second license plate (second license plate) at the front-door station AS 1 the "marker" can be stored in the same way in the system memory SS the central control ZST can be deleted again.

In ähnlicher Weise kann der »Merker« auch von der Reihenanlagestation aus bei vorliegender Berechtigung durch ein in der Wahlart der Reihenanlage gehaltenes Kennzeichen gelöscht werden.In a similar way, the "marker" can also be sent from the key station from with existing authorization through a held in the dialing type of the series system License plate to be deleted.

Da die Reihenanlagestation RS1 eine durch eine Außenstation getätigte zusätzliche Rufanschaltung an diese Außenstation an der Stellung der Schalter für Rufweiterschaltung nicht erkennen kann, ist es wesentlich, daß bei einer solchen Prozedur an beiden Stationen (AS 1 und RS 1) der Ruf bei einem ankommenden Anruf ankommt Damit wird verhindert, daß bei unterlassenem Löschen des »Merkers« an der Außenstation AS 1 und bei nicht besetzter Außenstation eine jetzt an der Reihenanlagestation anwesende Bedienungsperson einen ankommenden Anruf nicht bemerkt. Since the row system station RS1 is an external station additional call connection to this outdoor station at the position of the switch for Can not recognize call forwarding, it is essential that with such a Procedure at both stations (AS 1 and RS 1) the call for an incoming call arrives This prevents the Outdoor station AS 1 and, if the outdoor station is not occupied, now one at the row system station operator present does not notice an incoming call.

In einer vorgenannten Reihenanlage kann durch eine entsprechende Eingabe in den Kundendatenspeicher festgelegt werden, daß bei Abgabe eines dritten Kennzeichens von Seiten einer Außenstation nicht nur die für eine Reihenanlagestation oder für alle Reihenanlagestationen ankommenden Rufe parallel zur Außenstation weitergeleitet werden, sondern daß die bei einer bestimmten Gruppe von Reihenanlagestationen ankommenden Rufe parallel zur Außenstation geleitet werden. In an aforementioned series system, a corresponding Input in the customer data memory are set that when submitting a third Identification from the part of an outdoor station not only for a row system station or forwarded incoming calls to the front-door station in parallel for all row system stations but that those arriving at a certain group of key station stations Calls are routed parallel to the front-door station.

Aus dem Vorstehenden geht hervor, daß es nach dem erfindungsgemäßen Verfahren in einfacher Weise möglich ist, durch Eingabe eines ersten Kennzeichens einen zusätzlichen Ruf einer Außenstation zuzuleiten, durch ein zweites Kennzeichen von der Außenstation aus und durch ein drittes Kennzeichen von einer Reihenanlagestation aus diesen zusätzlichen Ruf wieder abzuschalten. From the foregoing it follows that after the according to the invention Procedure is possible in a simple manner by entering a first identifier to forward an additional call to an external station by means of a second identifier from the outdoor station and through a third identifier from a row system station to switch off this additional call again.

Claims

Claims: 1. Method for a microprocessor-controlled telephone private branch exchange, in particular series system with outstations, the subscriber stations over a central control with each other and with one of several trunk lines are connectable and the central controller is a customer data memory, a system memory and an operating field are assigned and still in the central controller an adaptation device designed as a microprocessor is provided for each outstation is, d a -characterized by the fact that if the customer data memory (KDS) is present, Authorization stored in the operating field (BF) from one of these authorizations corresponding outstation (AS 1 to ASX) a first from the associated adaptation device (AE 1 to AEX) into a code that can be read by the central control (ZST) certain identifier can be transferred to the central control system (ZST), which means that in the System memory (SS) a marker can be set which is activated when a call comes in a serial system station assigned to the first identifier in the customer data memory (KDS) (RSt to RSX) this call until the input of a second from the front-door station (AS 1 to ASX) passes the mark deleting mark to the outdoor station.

2. The method according to claim 1, characterized in that an the serial system station assigned to the first identifier in the customer data memory (KDS) (RSt to RSX) a flag in the dialing mode of the key system System memory (55) - if entered - the deleting identifier can be entered.

3. The method according to claim 1, characterized in that ßaß all calls from the front-door station to a group of row system stations (RS 1 to RSX) (AS.1 to ASX) by entering a third identifier from the front-door station (AS 1 to ASX) can be fed in parallel.

The invention relates to a method for a microprocessor-controlled Telephone private branch exchange, in particular a series system with external stations, whereby the subscriber stations via a central control with each other and with each one of several trunk lines can be connected and the central controller a customer data store, a system store and an operational field are allocated and one as a microprocessor in the central controller for each outstation trained adjustment device is provided.

In the case of a microprocessor-controlled telephone exchange, in particular in an aforementioned series system, each function key is on the subscriber stations (including the dialing keys) are assigned a specific digital code that is assigned by a Signal processor and is processed by a switch processor. Should one Dialing via a continuing line (e.g. exchange line), then will the actual, outgoing dialing impulses are formed by the central control. The connection between the row system stations and the central control is four-core. Two lines are used for signal transmission (code transmission) and two lines are used for voice communication. Are the row system outstations assigned, then the connection between the station and the central controller is two-wire. The choice is made by the front-door station in the form of the number of pulses and it is therefore to provide an adaptation device for each outstation in the central controller.

Such private branch exchanges are already known (Teletechnik 81 - Interface for external, external auxiliary parts set of the Conline E). Are there Ordinary telephones with rotary dials as front-end stations in the series system provided, which, as already mentioned, are connected via two-wire connections. With such a series of systems it is basically - possible and known - call forwarding z. B. from a first line system station to a second line system station or to an outdoor station. Certain switches are provided for this. An incoming call for the first station then goes to the second station or to Outstation. If one assumes that z. B. the outstation is a private station is that outside of business hours at a certain key system station incoming calls are to be received, then you will by switching over at the key system station carry out the call forwarding. This call forwarding must always be in the area of the Series system, so usually take place on the company premises.

The object of the invention is now to consist in a method to find, with the help of which it is possible, if the call is not forwarded, from a certain outdoor station from all for the aforementioned row system station to forward incoming calls to the front-door station. The calls should therefore both the front-door station as well as the row system station. The latter is therefore important because there is no switch for call forwarding at the key system station was operated and therefore z. B. the next day by the operator forwarding of the call to the branch office cannot be recognized.

Incoming calls for the key system station would be without parallel Call assignment as with call diversion only go to the front-door station, which is now is no longer busy and therefore cannot answer an incoming call.

According to the method according to the invention, this object is achieved by that in the case of the customer data memory stored via the operating field Authorization from an outstation corresponding to this authorization a first from the associated adaptation device into one of the central control device readable identifier specific identifier to be implemented for central control is transferable, whereby a flag can be set in the system memory, which in the case of an incoming call to one assigned to the first identifier in the customer data memory Row system station this call until the entry of a second from the outdoor station delivered the mark deleting mark of the outdoor station.
