Description

In gleicher Weise läßt sich eine Datenverbindung zur zentralen Datenverarbeitungseinrichtung DV hersteilen. Eine solche Datenverbindung kann entweder durch Wahl einer vorgegebenen Kennzahl mit der Wähleinrichtung des Telefons FG oder aber durch Einlegen bzw. Einstecken einer gelochten Karte in einen Leser als Datenendgerät DE eingeleitet werden, der zunächst die entsprechende Kennzahl und nach Abruf durch die Ein-AusgabesteuerungE,'A-ST der Datenverarbeitungseinrichtung DV die eigentlichen Daten aussendet. Auch eine Datenverbindung wird in der Regel unmittelbar nach Auftrennen der Teilnehmerschleife ausgelöst. A data connection to the central data processing device can be established in the same way Manufacture DV. Such a data connection can either be by choice a predetermined code with the dialing device of the telephone FG or through Insertion or insertion of a perforated card into a reader as a data terminal DE are initiated, the first the corresponding code and after being called by the input-output control E, 'A-ST of the data processing device DV is the actual Sends out data. A data connection is also usually opened immediately after it has been disconnected the subscriber loop triggered.

Gemäß der Erfindung unterbleibt jedoch die sofortige Auslösung einer Datenverbindung, wenn es sich um Teilnehmerstellen mit Datenendgeräten handelt, die eine Vielzahl von gleichartigen Verbindungswünschen erwarten läßt, z.B. bei einem Kartenleser zur Meldung des Arbeitszeitbeginns oder -endes von Angehörigen eines Unternehmens im Rahmen einer gleitenden Arbeitszeit. Ein solches Endgeräts läßt sich entweder an Hand des Identifizierergebnisses oder aber an Hand des gewünschten Betriebsprogrammes der Datenverarbeitungseinrichtung zur Behandlung der ermittelten Daten erkennen, wobei die tYberwachung durch die Zentralsteuerung ZST oder aber durch die Datenverarbeitungseinrichtung DV selbst vorgenommen werden kann. According to the invention, however, there is no immediate triggering of a Data connection, if it is a question of subscriber stations with data terminals, which allows a multitude of similar connection requests to be expected, e.g. at a card reader for reporting the start or end of working hours for relatives of a company as part of flexible working hours. Such a terminal can either be based on the identification result or on the basis of the desired one Operating program of the data processing device for handling the determined Recognize data, with the monitoring by the central control ZST or else can be carried out by the data processing device DV itself.

Die bei einer derartigen Datenverbindung vorzunehmende Auslösung wird um eine vorgegebene Zeitspanne, z. B. 15 Minuten. verzögert. Während dieser Zeitspanne bleibt der bestehende Verbindungsweg zwischen der beteiligten Teilnehmerschaltung TS und belegten DatenübertragungDUe im Koppelnetzwerk KN unabhängig von der Auftrennung der Teilnehmerschleife durchgeschaltet, so daß bei erneuter Dateneingabe durch einen anderen Benutzer desselben Datenendgerätes DE die erneute Verbindungsherstellung entfällt. Nach jeder Dateneingabe wird die Zeitspanne neu begonnen, so daß ein einmal aufgebauter Verbindungsweg wie eine Standleitung über einen längeren Zeitraum zur Verfügung steht. Das Ende des Auslöseverzuges kann entweder in der Datenübertragung selbst oder aber zentral durch die Zentralsteuerung erfolgen. Besonders einfach läßt sich auch eine Überwachung durch die Datenverarbeitungseinrichtung selbst mit Hilfe eines entsprechenden Programmes durchführen.The triggering to be carried out with such a data connection is by a predetermined period of time, e.g. B. 15 minutes. delayed. During this period the existing connection path between the subscriber circuit involved remains TS and occupied data transmission DUe in the coupling network KN regardless of the separation the subscriber loop switched through, so that when data is entered again by a other users of the same data terminal DE to re-establish the connection not applicable. After each data entry, the period is restarted, so that a once established connection path like a leased line over a longer period of time Available. The end of the trigger delay can either be in the data transmission itself or take place centrally through the central control. Particularly easy can also be monitored by the data processing device itself Carry out the help of an appropriate program.

Ist das DatenendgerätDE z. B. an die Anschlußleitung eines Pförtners angeschaltet und soll während des Auslöseverzuges über die Anschlußleitung ein Telefongespräch geführt werden, so kann die Auslösung der bestehenden Datenverbindung zwangläufig durch Senden eines gesonderten Datenzeichens, z. B. If the data terminal DE z. B. to the connection line of a porter switched on and should make a telephone call over the connecting line during the release delay then the existing data connection can inevitably be triggered by sending a separate data character, e.g. B.

Ende der Übertragung, herbeigeführt werden. Der Teilnehmer erkennt die Notwendigkeit zur Aussendung dieses Zeichens in einfacher Weise daran, daß er nach Abheben des Handapparates seines Telefons FG kein Wählzeichen erhält. Infolge der geschlossenen Teilnehmerschleife wird nach Auslösung der Datenverbindung ein Wählsatz WS mit der anfordernden Teilnehmerschaltung TS verbunden, was dem Teilnehmer durch das Wählzeichen angezeigt wird. Danach kann mit der Wahl begonnen werden.End of transmission. The participant recognizes the need to send out this sign in a simple manner because he after picking up the handset of his telephone FG does not receive a dialing signal. As a result the closed subscriber loop is activated after the data connection has been released Dial set WS connected to the requesting subscriber circuit TS what the subscriber is indicated by the dialing character. The election can then begin.

Claims

Claims: 1. Circuit arrangement for telephone systems that cooperate with a data processing facility and in which, among other things Transferring data from the individual subscriber stations to the data processing device are, characterized in that send out depending on the type of data Subscriber station (e.g. terminal for working time recording DE) or the type of sent data triggering the data processing device (DV) set up Data connection path is delayed differently after cancellation of the assignment, in such a way that when new assignments take place within the specified trigger delay time by the same subscriber station (TLN) this immediately and without renewed connection establishment is connected to the data processing device (DV).

2. Circuit arrangement according to claim 1, characterized in that the respective effective release delay through a separate data character (e.g. end the data transmission) can be canceled and thus the subscriber station (TLN) for other Connections is released.

It is already known to existing telephone networks for transmission of additional data and in connection with a central data processing device special services, such as B.

Obtaining information, placing orders or collecting specified Data, to enable.

Either the telephone itself or a separate device, e.g. B. a punch card reader, serve. The production a data processing takes place in the same way as the production of a Telephone connection by dialing a predetermined code, which when using a separate data terminal can also be transmitted automatically.

Individual data services mean that a number of similar Data from a. Subscriber station from time-accumulated are to be expected, z. B. in Within the scope of the recording of working hours, the data on the start and end of work for the individual Workers.

This usually leads to excessive stress on the control equipment the telephone system and thus an impairment of telephone traffic, especially if these data services are set up subsequently. The invention now circumvents these difficulties by transmitting depending on the type of data Subscriber station or on the type of data sent, the triggering of the data processing device established data connection path after cancellation of the occupancy delayed differently is, in such a way that when taking place within the predetermined release delay time New assignments by the same subscriber station immediately and without renewed Connection establishment is connected to the data processing device.

As a result of the trigger delay for individual data services, in easily achieved the advantage of a dedicated line, since the connection is under certain requirements do not have to be rebuilt every time data is entered. The control devices the telephone system are thereby significantly relieved. On the other hand, that's for the data transmission does not require the telephone traffic constantly withdrawn like a real leased line.

The necessity of the release delay arises either through the Participation point itself, if this is only this. a data service allows or else from the data entered, which the corresponding utility program of the data processing device mark.

It is also useful that the respective effective release delay can be canceled by a separate data character, so during the time in which the data connection is still switched through as a result of the trigger delay, a telephone connection can be set up from the same subscriber station.

Further details are shown on the basis of the drawing Block diagram of an exemplary embodiment explained in more detail: The subscriber station TLN consists of a telephone setFG and a data terminal DE in the form a card reader. Both devices are connected to the same connection line that Via a subscriber circuit TS to the switching network KN of the exchange connected. This is used in connection with the central control ZST for production the connection you want in each case.

Furthermore, a WS dial set to accommodate the desired Connection characterizing dialing digits and a connection set VS for telephone connections shown. Data connections to the central data processing device DV run on the other hand via the D Ue transfer and the input-output control that is common to all I / O ST.

These transmissions are used in a known manner to monitor the Connection and adaptation of the different sign systems as well as the implementation of the data.

The process for establishing a connection is well known Way as follows: As soon as the handset of the telephone FG at the subscriber station TLN is picked up, this recognizes the subscriber circuit TS and reports .es to the central control ZST. This identifies the subscriber station to be registered and provides it via the coupling network KN establishes a connection to one of the elective sets WS. The participant then receives the dialing character. and dials the desired phone number recorded by the dialing set and is transferred to the central control. This determines the most favorable connection route from the requesting subscriber circuit TS through the switching network KN to a Free connection set VS and, in the case of an internal connection, continue to the desired one Subscriber and switches through the selected connection path. After manufacture The connection set VS monitors the continuation of the desired connection. To The existing connection path is immediately terminated triggered.
