Abstract

PURPOSE:To transfer the same user/user's information(UUI) from an arbitrary general data terminal(DTE) to plural ISDN terminals(TRM), and to simultaneously transmits the same message to the entire TRM in an emergency. CONSTITUTION:When a DTE 3 calls, a CPU 11 detects the calling through a data adaptor 6 from a data line circuit(DLC) 9, and connects the DLC 9 through a time division switch(TDSW) 10 with a UUI trunk circuit(UUT) 13. Then, a UUI message and the other side line number (subaddress of TRM as necessary) to be communicated to the other side are input and set from the DTE 3, according to a preliminarily set procedure. At that time, when a line number 4000 is input, the UUT 13 transmits the line number 4000 and a layer 3 message including the UUI to the CPU 11. The CPU 11 connects the UUT 13 through the TDSW 10 with an ISDN line circuit(ILC) 7 when receives the layer 3 message, and transfers the UUI from the UUT 13 to TRM 1 and 4.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a user-to-user information transfer system, and more particularly to a UUI transfer system in a digital private branch exchange that transfers ISDN user-to-user information (hereinafter referred to as UUI) to an ISDN terminal of an extension.

0002

2. Description of the Related Art Conventionally, the UUI transfer method in this type of digital private branch exchange only notifies one designated ISDN terminal of the UUI sent from an accommodated ISDN terminal.

0003

[Problems to be Solved by the Invention] The UUI transfer method of the conventional digital exchange described above only notifies the UUI set in an ISDN terminal to one terminal specified by a request from that ISDN terminal. In order to notify a plurality of ISDN terminals connected to a plurality of lines, it is necessary to perform a UUI transmission operation for the number of lines. Another drawback is that UUI can only be sent from ISDN terminals.

0004

[Means for Solving the Problems] The user-to-user information transfer system of the present invention is designed to connect a plurality of ISDN terminals accommodated in a time division switch of a digital private branch exchange connected to an ISDN, a data terminal for setting a UUI, and a data terminal for setting a UUI. The information processing apparatus is characterized by comprising a UUI setting means for setting a notification destination of the UUI from a data terminal, and a UUI transfer control means for transferring the UUI to the notification destination.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the UUI transfer method of the present invention.

In the digital private branch exchange of this embodiment, the ISD
N terminals (hereinafter TRM) 1, 2 and 4, 5 are I
Through SDN line circuits (hereinafter referred to as ILC) 7 and 8,
Further, a data terminal (hereinafter referred to as DTE) 3 is connected to a time division switch (hereinafter referred to as TDSW) 10 via a data adapter (hereinafter referred to as ADP) 6 and a data line circuit (hereinafter referred to as DLC) 9. Furthermore, the TDSW10 has an ISDN trunk circuit (
Also connected to the TDSW 10 is a UUI trunk circuit (hereinafter referred to as UUT) 13 which is connected to the ISDN 14 via the ITK (hereinafter referred to as ITK) 12 and sets the UUI and notification destination from the terminal. And ILC7, 8, DLC9, TDSW10,
ITK12 and UUT13 are central processing units (hereinafter referred to as CPU)
11.

Next, regarding the operation of this embodiment, the TRM connected to the line with line number 4000 (sub address 00
1), TRM4 (subaddress 002) and TRM2 (subaddress 0) connected to the line with line number 4100
01), TRM5 (subaddress 002) will be described as an example.

First, when the DTE 3 makes a call, the CPU 11 detects the call from the DLC 9 via the ADP 6, and
is connected to the UUT 13 via the TDSW 10.

[0010] Next, from the DTE 3, according to a predetermined procedure, the user inputs and sets the UUI message and the other party's line number (if necessary, the subaddress of the TRM) to be notified to the other party.

[0011] Here, line number 4000 (TR if necessary)
When the subaddresses 001, 002 of M1, 4 are input, the UUT 13 sends the line number 4000 and UU to the CPU 11.
Send a layer 3 message containing I. When the CPU 11 receives this layer 3 message, it connects the UUT 13 and the ILC 7 via the TDSW 10, and transmits the T from the UUT 13.
Transfer the UUI to RM1 and RM4.

[0012] Note that the destination of UUI transfer is TRM2,5.
In this case, from DTE3 to line number 4100 (T if necessary)
If the sub-addresses 001, 002 of RM2, 5 are input, the CPU 11 performs the same process to
The UUI is transferred to RM2 and RM5.

[0013]

Effects of the Invention As explained above, the present invention enables the transfer of UUI from any general data terminal to an ISDN terminal, and also uses the D channel to transfer the UUI. Multiple ISDs can be connected in one operation because they do not get busy like channels.
This has the effect that the same UUI can be transferred to N terminals.

Therefore, when the present invention is used, it is possible, for example, to send a conference notification to only those who need it from a personal computer or the like to the ISDN terminal that person is using, or to send the same notification to all ISDN terminals in an emergency. Can send messages.
