Abstract

PURPOSE:To fulfill a telephone reservation function further by storing up to extension numbers of a reception side in case of the telephone reservation and connecting automatically an external line to an extension when no reply is given to a telephone reservation reply tone. CONSTITUTION:In applying facsimile communication between facsimile equipments 1 and 5, when telephone reservation is applied from the facsimile equipment 1 by depressing a telephone button, an extension telephone number addition section 11 adds a know telephone number in advance to a telephone number. When the facsimile communication is finished and handset is not hooked off even if a reply tone of telephone reservation is sent by the facsimile equipment 5, the facsimile equipment 5 holds the extension number sent before, the extension number is sent to a PBX from an automatic dial section 27 and the line section 12 is controlled through switching to connect the facsimile equipment 5 to the extension side, that is, the PBX side. Thus, the extension, e.g., No. 7, is called by the PBX and the telephone set of the facsimile equipment 1 and the extension of the opposite party are connected to fulfill the telephone reservation function.

Description

[Detailed description of the invention] [Table of contents] Overview Industrial field of application Prior art (Fig. 5) Problems to be solved by the invention Means for solving the problems (Fig. 1) Working examples ( 1) Structure of the embodiment (Figs. 2 and 3) (2) Operation of the embodiment (Fig. 4) Effects of the invention [Summary] When a telephone reservation is made by facsimile, when a call is made by the telephone reservation, If there is no response from the other party, the two lines are switched from the outside line to the extension line, allowing you to connect to the person in charge of the extension line.

C. Industrial Application Field] The present invention relates to an extension connection control method based on facsimile telephone reservation, and in particular, when there is no answer even if there is a call based on the facsimile telephone reservation, the present invention is concerned with a system for controlling extension connections based on facsimile telephone reservation. 2, relates to a device that automatically connects the other party's extension.

[Conventional technology]

Most facsimiles are installed with automatic reception. In addition, the installation location is often within an office where normal office work is performed. The facsimile machine is equipped with a telephone reservation function, which allows telephone communication with the other party immediately after the facsimile is completed. In this case, the telephone reservation operation may be performed during facsimile transmission.

As shown in Figure 5, 1 Nippon Telegraph and Telephone Corporation (NTT
) has multiple facsimile machines 41, 42, 4 on the exchange 44.
3... is connected and the facsimile 41 is currently conducting facsimile communication with the receiving facsimile 45. For example, by pressing the telephone button from the facsimile 41 side, a call is reserved.

Then, when the facsimile communication between the facsimile machine 41 and the facsimile machine 45 is completed, the telephone reservation process that was input when the telephone button was pressed during the second communication is performed.
Facsimile 45 produces a ring tone, and telephone communication can now take place between facsimiles 21 and 25.

[Problem that the invention seeks to solve]

By the way, when you make a telephone reservation, even if the fax machine outputs a telephone reservation response tone such as "Blue, Blue" after the facsimile communication is finished, if there is a person in charge in front of the fax machine, the answer will be there and you can still make the telephone reservation call. becomes. However, when the person in charge is not in front of the fax machine, few people understand the meaning of this response tone.
Since it is not known that a call request based on a telephone reservation has been made, no response processing is performed in response to the call request. Therefore, in FIG.

When you make a telephone reservation, the data sent from the facsimile 21 that made the telephone reservation is transferred to the NTT exchange 44.
After the reception is completed, the facsimile 45 emits a response tone "Blue, Blue" indicating this telephone reservation, but if nine people do not pick up the receiver, the line will be disconnected.

When the line is disconnected in this way, the sender calls again in order to convey the message, ◎ via NTT's exchange 44 and the other party's PBX 46, and then calls the person in charge at the receiving end on that extension. For example, I was calling using the number 47. In addition, 48 in FIG. 5 also indicates an extension telephone.

For this reason, there are few cases where Kirikaku's telephone reservation function is effectively used.1 Normally, reservations could be made by telephone, but T
Therefore, the purpose of the present invention is to store the extension number of the receiving party when making a telephone reservation, so that even if the telephone reservation is made after one communication This provides an extension connection control system based on a factor i telephone reservation in which connection is made to the extension telephone when there is no response.

[Means for solving problems]

To achieve the above object, as shown in FIG.

For example, the facsimile machine 1 is provided with an extension telephone number addition section 11, and the line section 12 of the facsimile machine 5 is formed with an internal/external line switching circuit.

In Figure 1, 2.3 is a facsimile.

4 is an NTT exchange, 6 is a PBX, 7 to 9 are extension phones,
10 is a facsimile.

During facsimile communication between facsimile 1 and facsimile 5, when a telephone button is pressed from facsimile 1 to make a telephone reservation, a known extension telephone number is also added in advance and sent.

[For production]

When the facsimile communication ends and the facsimile 5 does not pick up the receiver even though the answer tone for telephone reservation is emitted, the facsimile 5 retains the extension number sent earlier and transfers this extension number to the PBX. Sending, facsimile 5
Connect the line section 12 to the extension side, that is, to the PBX side.
Switch and control. As a result, the optical extension telephone, for example 7, is called by the PBX 6, so that the facsimile telephone 1 and the other party's extension telephone are connected and a call can be made.

In this case, a case will be described in which the facsimile 1 shown in FIG. 1 communicates with the facsimile 5 having an internal/external line switching function.

■ First, dial the telephone number of facsimile 5 from facsimile 1, and then faxes 1 and 5 will be connected via fiNTT exchange 4.

At this time, the contacts of each relay r right to r16 are in the state shown in FIG. Then, a 16Hz signal tone indicating the transmission of facsimile 1 is detected by the 16H2 detection circuit 26 and notified to the MPU 23.

■ Relay rl for facsimile communication of MPU23.
The + possible contact is connected to contact C2 to hold the line. As a result, the facsimile signal is (rll-Cs)
-(rl2-cs)-DC regeneration circuit 29-(r)s
-C1) - From the line section 12 via the DC regeneration circuit 31 to the modem 21. The data is transmitted to the facsimile transmitting/receiving section 22, data is exchanged, and facsimile communication is performed.

■ When facsimile communication is being carried out in this way,
Input button 35-O of input operation section 35 of facsimile 1
When the extension number entry capo 35-1 is operated, the extension number corresponding to the extension number entry capo 35-1 is read out from the extension holding section 36 by the extension number extraction section 37, and is sent to the telephone reservation control section 38. This extension number is inserted into the created telephone reservation signal and sent to the facsimile 5.

This telephone reservation signal is sent to the facsimile transmitting/receiving section 22.
Since the information is transmitted to the PU 23, the MPU 23 extracts this extension telephone number and recognizes that a telephone reservation has been made. And when the facsimile communication ends.

The MPU 23 outputs a reserved call tone to the facsimile 5. At this time, the MPU 23 controls the relay rlz to switch its movable contact to the contact C1 side.

When the outside line telephone 32 is hooked off by this telephone reserved tone, a telephone call is made by this tone.

Note that this hook-off can be detected by the reverse detection circuit 25 due to the polarity change of the outside line.

(2) However, even if this telephone reservation tone is output a certain number of times, the outside line telephone 32 is not hooked off.

Call control to an extension telephone is performed as follows.

First, (rls-Cx) p (rla4-Ct) MPU2 so that the movable contacts of each relay are switched to the O state.
ADR section 27 (rls-Cz) (rla-Ct
) - reverse detection circuit 28 - an extension circuit is formed.

Then, the MPU 23 notifies the ADH 27 of the call originating from the extension number held in advance. Accordingly, ADR27 is (r
1, -"x) (rl4-C1) - Reverse detection port g28t - An extension call is made to the PBX6.

(2) Along with this extension call, the MPU 23 performs control to turn on the contact CI of the relay rls.

In this way, if the telephone with the extension number via the PBX 6 hooks off, the outside line-reverse detection circuit 25- (r

The KMPU 23 controls each relay so that a circuit of -C,) -(rl4-C1) is formed. In this way, facsimile 1 and the desired extension telephone are connected via PBX 6, so that the telephone can be passed through. ■ When this telephone passage is completed, the hook-on state is established, and the polarity of the line is reversed. It is detected by the reverse detection circuit 28 and reported to the MPU 23. This MPU
23 returns the operation of each relay to the standby state shown in FIG.

〔Effect of the invention〕

According to the present invention, if there is no response even after making a telephone reservation, the two lines are switched from an outside line to an extension line.

By extension number included in the telephone reservation signal.

Since the telephone can be automatically routed to the person in charge of the extension telephone via the PBX, the telephone reservation function can be further enhanced.
