Description

Description: TECHNICAL FIELD The present invention relates to a facsimile storage and exchange device, and more particularly to a facsimile storage and exchange device employing a dial-in system.

(Prior Art) Recently, with the spread of facsimile apparatuses, facsimile storage and exchange apparatuses for performing various communication services have appeared.

In this facsimile storage and switching apparatus, a plurality of extensions and external lines are accommodated, facsimile communication is performed with a facsimile terminal connected to the internal and external lines, and connection and exchange between extensions and between an extension and an external line are performed. Is going. For example, a facsimile storage and exchange device receives a message from an extension facsimile terminal, temporarily stores the message in an image memory, and then transmits the message to a designated destination. On the other hand, various communication services are provided, such as a proxy reception service for receiving a message and temporarily storing it in an image memory, and then transmitting the message to a designated extension, and a direct exchange service for directly connecting an extension and an outside line.

In this facsimile storage and switching apparatus, there is a dial-in method for receiving an extension using a dial-in number registered for each extension using a dial-in number designated by the central office.

Conventionally, in this dial-in system, the dial-in number is always associated with the extension number, and the function setting of the facsimile storage and exchange device for each extension number is either a direct connection function or an alternate reception. It is a target. Therefore, if the alternate reception function is set as the extension function, only the alternate reception is performed for the incoming call to that extension, and if the direct connection function is set as the extension function, the incoming call to that extension is not received. Direct connection takes precedence,
When the extension cannot be received due to busy or the like, the substitute reception is performed.

(Problems to be Solved by the Invention) However, in such a conventional facsimile storage and exchange apparatus, in the dial-in system, all dial-in numbers are assigned to extensions, and the function of the extension is direct connection or alternate reception. Therefore, if alternate reception is set as a function of the extension, if an external line requests the facsimile storage and exchange device to perform the alternate reception, it is possible to perform the alternate reception by calling the extension.
Conversely, there is a problem that only alternate reception can be performed for the extension, and it is not possible to directly communicate from the outside line to the extension. Conversely, if all extensions are set to the direct connection function, even if you want to request the facsimile storage and exchange device to perform alternate reception, if the called extension is available, it will be directly connected, and the alternate reception request will be made. There was a problem that it could not be done.

(Object of the Invention) Therefore, the present invention provides a dial-in number which is larger than the number of extensions of a facsimile storage and exchange apparatus adopting a dial-in method, assigns an extension number to the dial-in number, and sets the remaining dial-in numbers. By setting the alternate reception function to the number, you can consciously select direct communication with the extension and alternate reception from the outside line,
It is an object of the present invention to improve the usability and convenience of a facsimile storage and switching apparatus by making it possible to perform alternate reception without changing the incoming call form of an extension.

(Constitution of the Invention) In order to achieve the above object, the present invention is connected to a plurality of facsimile terminals via a plurality of extensions and an outside line connected to a central office, and an external line is connected to the central office by a dial-in number. A dial-in method that allows you to call an extension directly from a telephone. An alternate reception function that receives a message from an outside line, temporarily stores it in a storage unit, and then sends it to a designated extension facsimile terminal, or a direct exchange function that directly connects an extension to an outside line In the facsimile storage and exchange apparatus provided with the above-mentioned functions, the number of extensions to be received and the assignment relationship of dial-in numbers are set as follows: the number of extensions is smaller than the dial-in number, and the proxy reception function is provided for dial-in numbers exceeding the extension assignment. It is characterized in that only one is set.

 Hereinafter, a specific description will be given based on examples of the present invention.

 1 to 3 are views showing an embodiment of the present invention.

External LO ₁ ~LO _m is connected to the station switch, a facsimile store and forward device 1 receives the service Dialing from the station exchanger. Line control unit 2 connected to external LO ₁ ~LO _m and the communication control unit 3, the connection between the external line LO ₁ ~LO _m and extension LI ₁ ~LI _n connection and extension LI ₁ ~LI _n and the communication control unit 3 It operates as an exchange to perform.

The communication control unit 3 includes a modem, an encoding / decoding unit, etc., and exchanges facsimile control signals, and changes transmission / reception signals.
A facsimile communication process is performed by performing demodulation and image data compression / reproduction processes.

The storage unit 6 stores the image data of the message, and stores the image data.
Controls writing and reading of image data to and from the storage unit 6.

The registration unit 5 sets various parameters used in the facsimile storage and exchange apparatus 1, particularly, extension function parameters and the like according to the present invention as shown in FIG.

The system control unit 7 has a CPU (Central Processing Uni
t), ROM (Read Only Memory), RAM (Random Access M)
emory) and the like, and the control program of the facsimile storage and exchange device 1 is stored in the ROM. The system control unit 7 controls each unit of the facsimile storage and exchange apparatus 1 based on the program in the ROM and the setting parameters of the registration unit 5 to execute the processing as the facsimile storage and exchange apparatus 1.

 Next, the operation will be described.

The facsimile store and forward device 1 in response to a request from the extension LI ₁ ~LI _n and external LO ₁ ~LO _m to provide various communication services. For example the extension LI ₁ through ～LI _n extension facsimile terminal F ₁ timer transmission service requested by the to F _n, external
A direct connection or interception services etc. to specified extension against incoming call from LO ₁ ~LO _m.

In particular, the facsimile storage and exchange apparatus 1 employs a dial-in method, and is provided with more dial-in numbers (DI numbers) than the number of contracted extensions LI _{1 to} LI _n . Now, as shown in FIG. 2, _{assuming that} the number of extensions LI _{1 to} LI _n is 4 and the number of DIs is 5, the extensions LI ₁ to “4” of the DI numbers are used. It is registered in the registering unit 5 by assigning "4" from the extension number "1" of ~LI _n. The alternate reception function (mode) of the facsimile storage and switching apparatus 1 is set to “5” of the DI number, and is registered in the registration unit 5. As a function of the extensions LI _{1 to} LI _n , as shown in FIG. 2, a direct communication, that is, a direct connection function is set, and as a connection form of each of the extensions LI _{1 to} LI _n , direct connection, alternate reception and There is. As described above, this alternate reception is used when the extensions LI _{1 to} LI _n cannot be directly received, and the facsimile storage and exchange apparatus 1 uses the external line LO ₁
Intercept incoming calls from ~ LO _m .

Therefore, the facsimile store and forward device 1, as shown in FIG. 3, when there is an incoming call from the outside line LO ₁ ~LO _m (step
S ₁ ), receives the DI number from the network (that is, the central office exchange) (step S ₂ ), and based on the DI number, the system control unit 7 searches the registration unit 5, and the designation of the DI number indicates the alternate reception. whether or not to specify (second reference Figure) checks (step S _3). If you can not intercept the extension LI ₁ ~LI _n and external LO ₁ ~LO _m specifying the DI number directly connected (step
S _4), returns to the initial state (Step S _5). At this time, if the corresponding extensions LI ₁ to LI _n cannot be received due to busy etc.,
The facsimile storage and exchange device 1 performs interception.

On the other hand, designated by the DI number at Intercept, it connects the external line LO ₁ ~LO _m and a communication control unit 3 stores the image data of the message received by performing an interception in the storage section 6 (step S ₆ ). Thereafter, the facsimile storage and exchange apparatus 1 calls the designated extensions LI _{1 to} LI _n , reads out a telegram from the storage unit 6, and reads the extension facsimile terminals F ₁ to F _n of the extensions LI _{1 to} LI _n.
And it sends it to return to the initial state (step S _7, S _8).

In this way, in a dial-in facsimile storage and exchange device, a contract for more dial-in numbers than the number of extensions is made, dial-in numbers are assigned to each extension, and an alternate reception function is set for the remaining dial-in numbers. By doing so, direct communication with the extension and alternate reception can be intentionally selected from the outside line, and alternate reception can always be performed without changing the incoming call form to the extension. As a result, the usability and convenience of the facsimile storage and exchange device can be improved.

In the above embodiment, the number of extensions LI _{1 to} LI _n is 4
Although there are five lines and five dial-in numbers, it is needless to say that the number is not limited to this.

(Effect) According to the present invention, direct communication with an extension and alternate reception can be intentionally selected from an external line, and alternate reception can be performed without changing the incoming call form of an extension. The usability and convenience of the device can be improved.
