Abstract

PURPOSE:To issue an outgoing response afterwards even by the opponent of outgoing being in busy by transmitting the originator number of a terminal to the terminal in busy, storing the originator number by the terminal receiving it, and issuing the outgoing to an originator after completing communication with another terminal. CONSTITUTION:A central processing control unit 3 is provided with a transmission means which transmits the originator number to the terminal in busy, when the opponent to whom the outgoing is issued is in busy. When the terminal 1 is in busy, the signal of the originator number outputted from the central processing control unit 3 of another terminal is supplied to the terminal 1 passing a signal line D, and is converted to an information signal for storage by a processor 1b, and is stored in a storage part 1a. When a null state is set after completing the communication in the terminal 1, the processor 1b reads out the originator number stored in the storage part 1a, and it is converted to an outgoing signal by an originator number conversion part 1c, then, the terminal of the originator issued in busy is called.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an Integrated Services Digital Network (hereinafter referred to as ISDN) terminal relay device, and particularly to an efficient connection system between terminals.

[Prior art] In recent years, ISDN (Integrated 5e
Although many communication services have been developed and utilized by ISDN terminals, a relay device is required to connect these ISDN terminals.

In this type of r SDN terminal relay device, when the telephone is busy, the exchange allows the caller to hear the busy tone, and when the caller hears the busy tone, the caller can call again later. There is.

[Problems to be Solved] However, with the above-mentioned conventional relay device, the busy tone sent out by the exchange is identified and only the caller can connect the terminal, so the caller cannot hear the other party's phone. There was the inconvenience of having to make multiple calls until the terminal was free.

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a comprehensive service digital network terminal relay device that allows connection to be made by the calling party and enables efficient terminal relay. be.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a comprehensive digital service network terminal relay device that connects terminals of the comprehensive digital service network through an exchange, and provides an integrated service digital network terminal relay device that connects terminals of the integrated service digital network by an exchange. The exchange is provided with a transmission means for transmitting the caller number of the terminal to the busy terminal, and a storage section for storing the caller number transmitted by the transmission means, and a caller number output from the storage section. The terminal is provided with a converting section that converts the information signal into a calling signal, and after the conversation ends, the converting section outputs a calling signal to call the caller's terminal that is calling during the call.

[Operation] According to the above configuration, when the other party is busy, the caller's number is transmitted by the exchange, and the terminal that is currently on the line stores the received caller's number in its memory. . and,
When the terminal that was busy is finished talking, the caller number in the storage unit is converted into a call signal by the conversion unit, and the caller is thereby called and the two terminals are connected. It turns out.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the configuration of an ISDN terminal relay device according to an embodiment, and FIG. 2 shows the internal configuration of the terminal.

In FIG. 1, the terminal 1 is configured so that an exchange switch 2 and a central processing controller terminal 1 can be connected to an ISDN network 5 via an ISDN network interface trunk 4, and a terminal 1 is connected to an ISDN network 5 via an ISDN network interface trunk 4. It is possible to talk to other terminals through the network 5.

The central processing control unit 3 is equipped with a transmission means for transmitting the caller's number to the terminal when the other party is busy.

In FIG. 2, a storage unit 1a stores the caller number received from the ISDN network 5, and this storage unit 1a
is provided with a caller number converter 1c via a processor lb. The caller number conversion section 1c receives the caller number information received by the terminal 1, and converts the caller number information signal output from the storage section 1a into a transmission signal to the caller.

The embodiment has the above configuration, and the operation when another terminal calls while the terminal 1 in FIG. 1 is busy will be described below.

When the terminal l is busy, the caller ID signal output from the central processing control unit (3) in the other terminal is supplied to the terminal l through the signal line. Then, in the terminal 4111 shown in FIG. 2, the caller number signal is output to the processor 1b via the caller number converter 1c, and the processor l
b, the caller number is converted into an information signal for storage, and thereby the caller number is stored in the storage section 1a.

Then, when the conversation on the terminal Jal ends and the state becomes empty, the processor 1b reads out the caller number stored in the storage unit 1a, so the caller number information signal is converted into a call signal by the caller number converter IC. The terminal of the caller who is currently on the line will be called by this transmission signal.

[Effects of the Invention] As explained above, according to the present invention, the caller number of a terminal is transmitted to a busy terminal, and the terminal that receives one caller number memorizes this and transmits it to other terminals. After the conversation with the terminal is finished, it is now possible to make a call to the above caller, so that the connection between the terminals is not only established by the caller, but also by the other party who was currently on the line. will be possible.

Therefore, there is no need for the caller to make repeated calls until the other party's terminal is available, unlike in the past, and there is an effect that efficient terminal relay can be achieved.

FIG. 1 is a block diagram showing the structure of an ISDN terminal relay device according to an embodiment, and FIG. 2 is a block diagram showing the internal structure of the terminal.

Claims (1)

[Claims] In a integrated service digital network terminal relay device that connects integrated service digital network terminals through a switch, a transmission means is provided that transmits the caller number of another terminal when a terminal is busy to the busy terminal. Provided in the above exchange,
The terminal device is provided with a storage section that stores the caller number transmitted by the above-mentioned transmission means, and a conversion section that converts the caller number information signal outputted from this storage section into a transmission signal, and after the conversation ends, the A comprehensive service digital network terminal relay device characterized by outputting a calling signal from a converting section to call a caller terminal that is calling during a call.
