BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ISDN (hereinafter referred to as ISDN) telephone, and more particularly to an ISDN telephone that is a subscriber terminal that is matched with an ISDN exchange that is currently serving or scheduled to serve a subscriber. .

In this regard, ISDN is a digital communication network that integrates and provides various services, and ISDN is an integrated service digital communication network that enables to provide not only voice but also image and data services by developing voice communication.

In this case, the services to be integrated are mainly narrowband services such as telephone, facsimile, teletex, telemetry, telewriting, and data terminal.

Typical features of ISDN include the fact that the subscriber and the communication network are connected through one circuit so that various services can be comprehensively provided, and the connection between the subscriber and the communication network is digital.

In other words, the subscriber network is digitalized and various services are integrated thereon.

In ISDN, there is an advantage that a variety of voice and non-voice services can be integrated and processed, which is possible because all information processing is performed by digital method.

Therefore, in ISDN, circuit switching and packet switching can be provided simultaneously, and transmission is digital.

ISDN provides a common access point for existing circuit-switched and packet-switched networks, and has the advantage of allowing various information resources in the network to be shared.

In other words, it is possible to put various databases in a communication network and use them jointly by all subscribers and service providers.

In addition, ISDN can provide various communication processing and information processing functions, and has advantages such as facilitating operation and management of a communication network.

In addition to the existing voice exchange, an era of non-speech exchanges has now opened, and many terminals have been developed.

When the ISDN exchange was already developed and entered into service to general subscribers, it was revived and faced the need for ISDN terminals requiring quality and excellent functions for maximum service for subscribers for smoother ISDN service.

Therefore, if the present invention enables the display of the additional service code on the ISDN phone which is already commercially available for the smooth service of the ISDN, the subscribers may feel very satisfied in terms of service.

In addition, there are dozens of supplementary services of the ISDN exchange, but it is no exaggeration to say that most of the supplementary services are executed by the supplementary service identification code between the terminal and the exchange.

ISDN telephones differ significantly in their functionality compared to analog telephones used in traditional voice exchanges.

Apparently, there are many options such as Option Key and Liquid Crystal Display (LCD) display panel.

The ISDN telephone according to the prior art is currently in the state that many exchanges have been developed in Korea, and the service is practical. Here, basically, a voice service or a non-voice service is basically provided, and there are many additional services, but many subscribers are added. Using services is not enough.

The public relations activities of Korea Telecom may also have problems, but in reality, it is difficult for subscribers to access additional services, and it is very difficult to remember and use them even if they actually try to receive the service.

The present invention has been made to solve the drawbacks of the prior art, it is possible to provide a smooth additional service to subscribers by embedding the code of the ISDN additional service in the memory area of the ISDN phone to display on the LCD instrument panel in the ISDN phone The purpose is to provide an ISDN telephone.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention for achieving the above object is as follows.

Referring to FIG. 1, FIG. 1 is a block diagram showing an embodiment of an ISDN telephone according to the present invention. The S-line connecting connector 10 and the S-line connecting connector 10 for connecting an S-line and an ISDN telephone are shown in FIG. S-connector 12, which transmits signals from the ISDN telephone and receives the other party's signal through the S-connector, receives power from the S-connector 12 to the S-line, and supplies power to the ISDN telephone. The master displays the contents of the additional service according to the embedded data under the control of the central control unit 16 and the central control unit 16 controlling the overall operation of the ISDN telephone while communicating with the power control unit 14, the S connection unit 12. A storage unit 20 storing the additional service contents and outputting the additional service contents under control of the central control unit 16 so that the corresponding additional service contents can be displayed on the display unit 18, and the central control unit. 16 controls The voice control unit 22 for controlling the voice signal of the ISDN telephone by means of the voice control unit 22, the handset 24 for communicating with the voice control unit 22 for handset with the other party, and the central control unit 16 for communicating with the external computer system. Data connection unit 26 for controlling data communication, RS-232C connector 28 for connecting the data control unit 26 and an external computer system, and a telephone connection for connecting the voice control unit 22 and an external telephone. It comprises a connector 30.

Referring to FIG. 2, the present invention thus achieved is as follows.

First, the S line connection connector 10 connects the S line from the ISDN switch side to the ISDN telephone, and the S connection part 12 transmits a signal of the ISDN telephone to the ISDN switch side through the S line connection connector 10. Receive a signal from the ISDN exchange side.

Next, the power control unit 14 receives the power of the S line from the S connection unit 12 to make a variety of power to supply each power required for the ISDN telephone, the central control unit 16 communicates with the S connection unit 12 Controls the overall operation of an ISDN phone.

Subsequently, the display unit 18 displays the additional service contents according to the data stored in the storage unit 20 under the control of the central control unit 16, and the storage unit 20 stores the additional service contents for the display and then displays the central service contents. The control unit 16 outputs the corresponding additional service content to the display unit 18.

The voice control unit 22 controls the voice signal of the ISDN telephone under the control of the central control unit 16, and the handset 24 communicates with the voice control unit 22 to communicate with the other party as a user's handset. The data control unit 26 communicates with the central control unit 16 to control data communication with an external computer system.

In addition, the RS-232C connector 28 allows the data control unit 26 and an external computer system to be connected, and the telephone connection connector 30 connects the voice control unit 22 with an external telephone.

In this case, the additional service codes stored in the storage unit 20 will be described with reference to FIG.

FIG. 2 is a diagram illustrating an embodiment of additional service codes stored in the storage unit 20 according to FIG. 1.

The first English letter indicates the type of supplementary service, the following code is the service code according to it, and the rightmost description means the function expression of the corresponding supplementary service.

As described above, the present invention has an effect of enabling the subscribers to easily use the desired additional service by embedding the code of the ISDN additional service in the storage unit 20 and displaying it on the display unit 18 of the ISDN telephone. .
