Abstract

The system includes terminals and extension installations which are operated at ISDN multi apparatus links by a system utilising ISDN performance characteristics. In the analog terminal or extension installation is integrated a terminal adapter (TA) with A-B interfaces. The adapter contains an So interface, coder and decoder for converting analogue signals into digital signals and vice versa. The terminal adapter can be integrated with e.g. a facsimile apparatus.

Description

Die Erfindung betrifft eine Anordnung zum Betreiben analoger Endgeräte und/oder Nebenstellenanlagen an ISDN-Mehrgeräte- Anschlüssen zur Nutzung von ISDN-Leistungsmerkmalen.The invention relates to an arrangement for operating analog Terminal devices and / or private branch exchanges on ISDN multi-device Connections for the use of ISDN features.

Herkömmliche analoge Endgeräte, wie Telefone, Fax-Geräte oder Modems, können an ISDN-Netzen angeschlossen werden. Die Leistungsmerkmale des ISDN-Netzes sind durch die analogen Geräte jedoch nicht nutzbar.Conventional analog terminals, such as telephones, fax machines or Modems can be connected to ISDN networks. The Features of the ISDN network are due to the analog However, devices cannot be used.

Der Erfindung lag daher die Aufgabe zugrunde, analoge Endgeräte, die mit einem Mehrfrequenz-Wahlverfahren ausgestattet sind, ISDN-fähig zu schalten, so daß zusätzliche Leistungsmerkmale anwendbar sind.The invention was therefore based on the object, analog End devices using a multi-frequency dialing process are equipped to switch ISDN-compatible, so that additional Features are applicable.

Diese Aufgabe ist durch die Erfindung gelöst, wie sie im Patentanspruch dargelegt ist.This object is achieved by the invention, as in Claim is set out.

Anhand einer aus drei Figuren bestehenden Zeichnung wird die Erfindung nachfolgend näher erläutert. In der Zeichnung zeigen dieUsing a drawing consisting of three figures, the Invention explained in more detail below. Show in the drawing the

Fig. 1 die Anschlußkonfiguration eines Terminaladapters, die Fig. 1 shows the connection configuration of a terminal adapter, the

Fig. 2 das Blockschaltbild eines Fax-Gerätes mit einem Terminaladapter und die Fig. 2 shows the block diagram of a fax machine with a terminal adapter and

Fig. 3 die Zusammenfassung der Elemente nach der Fig. 2. Fig. 3 shows the summary of the elements according to Fig. 2.

Zum Nutzen von ISDN-Leistungsmerkmalen durch analoge Endgeräte wird ein Terminaladapter TA verwendet (Fig. 1). An diesen Terminaladapter TA sind analoge Endgeräte über die Eingänge a/b anschließbar, die somit an einem ISDN-Mehrgeräteanschluß betrieben werden können. Der Terminaladapter TA umfaßt eine S0-Schnittstelle sowie Codierer und Decodierer zum Umsetzen der analogen Signale in digitale Signale und umgekehrt. Am ISDN-Mehrgeräteanschluß kann für jeden der beiden analogen Anschlüsse eine eigene Rufnummer programmiert werden, so daß die Endgeräte unabhängig voneinander gleichzeitig betreibbar sind. Die unterschiedlichen Rufnummern werden z. B. mittels des Mehrfrequenzwahlverfahrens der Endgeräte programmiert.A terminal adapter TA is used to use ISDN features by analogue terminals ( FIG. 1). Analog terminal devices can be connected to this terminal adapter TA via inputs a / b and can thus be operated on an ISDN point-to-multipoint connection. The terminal adapter TA comprises an S 0 interface as well as encoders and decoders for converting the analog signals into digital signals and vice versa. A separate call number can be programmed for each of the two analog connections on the ISDN point-to-multipoint connection, so that the terminals can be operated independently of one another at the same time. The different numbers are e.g. B. programmed by means of the multi-frequency dialing method of the terminals.

Werden an einen Terminaladapter TA ein analoges Fax-Gerät oder eine analoge Nebenstellenanlage angeschlossen, so werden das Gerät bzw. die Anlage ISDN-fähig und verfügen über eine zusätzliche a/b-Schnittstelle (Fig. 2).If an analog fax machine or an analog private branch exchange is connected to a terminal adapter TA, the device or the system becomes ISDN-compatible and has an additional a / b interface ( FIG. 2).

Durch Integration des Terminaladapters TA in z. B. ein Fax-Gerät (Fig. 3), verfügt das Fax-Gerät über eine zusätzliche externe a/b-Schnittstelle.By integrating the terminal adapter TA in z. B. a fax machine ( Fig. 3), the fax machine has an additional external a / b interface.
