Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ISDN private branch exchange, and more particularly to an ISDN private branch exchange having a facsimile reception notification function for notifying a recipient when facsimile information is received.

[0002]

2. Description of the Related Art In facsimile communication using a private branch exchange accommodating a facsimile terminal, in order to confirm the transmission by a sender, the transmission of a telegram is a communication such as a telephone call other than the facsimile communication. It is necessary to notify the recipient on the receiving side by means of means, which is troublesome.

In order to save the above-mentioned trouble, many private branch exchanges with a reception notification function have been proposed.

For example, Japanese Patent Laid-Open No. 3-38 as shown in FIG.
There is a private branch exchange disclosed in Japanese Patent Publication No. 962.

The private branch exchange 201 has a telephone number storage unit 203 for storing the telephone numbers of the facsimile terminal 211 and the telephone set 214 in advance and a voice signal storage unit 204 for storing a voice signal indicating the completion of the facsimile communication.
And a control unit 202 that detects the completion of facsimile communication and transmits a voice signal to the telephone set 214.

When the facsimile communication is completed, the control unit 202 calls the telephone number of the telephone set 214 registered in the telephone number storage unit 203 corresponding to the facsimile terminal 211 and is stored in the voice signal storage unit 204. A voice signal indicating that the facsimile communication is completed is transmitted.

As described above, the transmission of the voice signal saves the sender from having to notify the recipient of the completion of communication by telephone.

[0008]

However, in the case of the above-mentioned conventional example, when the number of telephones is larger than the number of facsimile terminals, that is, when a plurality of users use the same facsimile terminal 211, telephones are used. 214
There is a problem that only the user who uses can confirm the reception of the electronic message at his / her desk.

The present invention has been made in view of the problems of the above-described conventional technique, and even when a plurality of users use the same facsimile terminal, the recipient automatically receives the facsimile. The purpose of the present invention is to realize a private branch exchange that can be notified in advance.

[0010]

An ISDN private branch exchange with a facsimile reception notification function of the present invention is information for analyzing an information element included in a call setting message of an incoming call in an ISDN private branch exchange accommodating a facsimile terminal and a telephone terminal. An analysis unit, a call path control unit that transfers the incoming call to either the facsimile terminal or a telephone terminal according to the analysis result of the information analysis unit, and the analysis result of the information analysis unit indicates that the incoming call is a facsimile. If it is information and indicates the called party number of the telephone terminal, it has a signal control section for sending a message indicating that a facsimile has been received for the called party number. Is characterized by.

[0011]

The procedure for setting up, maintaining and disconnecting the network connection in the ISDN user / network interface is defined by "ISDN user / network interface layer 3 circuit switching". Information exchanged between them is called a message, and defines the content of the communication to be performed thereafter.

The "call setup" message, which is a message for starting the call setup, includes a message that defines the "transfer capability" of the call as an essential item. By referring to the "transfer capability", the reception side can identify the transmission content transmitted thereafter. Further, by using the called address of the "call setting" message, another called party number of the transmitting facsimile terminal can be transmitted.

In the present invention, when a facsimile terminal is received, it is confirmed whether or not there is a telephone terminal which should be notified of an incoming call by referring to the destination address or the like. If there is such a called party number, a message indicating that a facsimile has been received is sent out by the signal control unit, so that regardless of the arrangement state or number of facsimile terminals or telephone terminals, the facsimile can be surely sent. Will be notified that has been received.

[0014]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the ISDN private branch exchange of the present invention.

The ISDN private branch exchange 1 of this embodiment accommodates a plurality of ISDN terminals and facsimile terminals. In the figure, the facsimile terminal 12 on the transmitting side is the public network 1
3, a state in which a message is transmitted to the facsimile terminal 11 accommodated in the ISDN private branch exchange 1 is shown.
The ISDN private branch exchange 1 connects the facsimile terminal 11 to the facsimile terminal 11 and the ISDN terminal 15 according to the transmission content of the facsimile terminal 12.

The ISDN private branch exchange 1 comprises a control unit 2, a signal control unit 5, an information analysis unit 6 and a speech path control unit 7.

The control unit 2 actually sets a communication path and performs a switch operation. The signal control unit 5 stores a message signal indicating that the facsimile information is received,
The operation of each terminal accommodated is controlled. The information analysis unit 6 receives the received content via the signal control unit 5, analyzes the “information transfer capability” in the “call setting message”, and determines whether the received content is voice information or facsimile information. Then, the analysis result is sent to the signal control unit 5 and the communication path control unit 7 via the signal control unit 5.

The ISDN voice terminal 15 is connected to the LE.
The signal control unit 5 includes a D lamp and a display device (both not shown), and causes the signal control unit 5 to perform the display operation of each of the display units of the accommodated terminal in accordance with the received content indicated by the analysis result of the information analysis unit 6. The call path controller 7 sets a call path.

When the call sent from the facsimile terminal 12 is the voice information to the ISDN terminal, the call path control unit 7 sets the call path 10 to place the call.
Incoming call to.

The call sent from the facsimile terminal 12 is facsimile information to the facsimile terminal 11,
If the called number shown in the address or the like in the "call setting message" indicates the ISDN terminal 15, the call path control unit 7 sets the call path 8 and receives the call at the facsimile terminal 11. Then, the signal control unit 5 sends a message indicating that the facsimile information has been received to the ISDN terminal 15 and turns on the LED lamp provided in the ISDN terminal 15, and the display unit displays "facsimile reception". Is displayed.

By the above operation, the recipient can confirm the reception of the facsimile without the sender having to perform any special operation.

In the embodiment described above, I
The terminals accommodated in the SDN private branch exchange have been described as ISDN terminals and facsimile terminals, but the terminals accommodated are not limited to these, and a normal (analog) telephone terminal can be accommodated by providing a terminal adapter between them. It is possible to do so, and even in this case, the configuration of the present invention can be naturally utilized.

[0024]

Since the present invention is constructed as described above, it has the following effects.

The effect that the facsimile is surely received regardless of the arrangement state and the number of the facsimile terminals and telephone terminals, and the user can immediately confirm the reception of the message addressed to himself / herself at his / her desk. There is.
