Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a facsimile storage and forwarding device, and particularly to a facsimile storage and forwarding device that employs a dial-in system.

(Prior Art) Recently, with the spread of facsimile devices, facsimile storage and forwarding devices that provide various communication services have appeared.

This facsimile storage and forwarding device accommodates multiple extension lines and external lines, and performs facsimile communications with facsimile terminals connected to the internal and external lines, as well as connecting and exchanging internal lines with each other and between extensions and external lines. Is going. For example, a facsimile storage and forwarding device receives a message from an extension facsimile terminal, stores it in the image memory, and then sends it to a specified destination.When a call is made from an outside line, the message is sent to the specified extension facsimile terminal. Various communication services are provided, such as an alternate reception service in which messages are received and stored in an image memory, and then sent to a designated extension, and a direct exchange service in which an extension and an outside line are directly connected.

In this facsimile storage and forwarding device, there is a dial-in method in which a call is received at an extension using a dial-in number registered for each extension and designated by a central office exchange.

Conventionally, in this dial-in method, the dial-in number has always been associated with an extension number, and the function setting of the facsimile storage and forwarding device for each extension number has two options: direct connection function or proxy reception. It is true.

Therefore, if the interception function is set as an extension function, only interception will be performed for incoming calls to that extension, and if the direct connection function is set as an extension function,
Direct connection is prioritized for incoming calls to that extension, and proxy reception is performed when that extension is busy and cannot receive calls.

(Problem to be Solved by the Invention) However, in such conventional facsimile storage and forwarding devices, in the dial-in system, all dial-in numbers are assigned to extensions, and the functions of the extensions include direct connection or interception. If the extension function is set for interception, if you request the facsimile storage and forwarding device to receive an interception from an external line, you can receive the interception by placing a call to that extension. Conversely, there was a problem in that only proxy reception could be performed for that extension, and even if one wanted to communicate directly with that extension from an outside line, it would not be possible. Conversely, if all extensions are set to the direct connection function, even if you want to request interception to the facsimile storage and forwarding device, if the calling extension is available, it will connect directly and you will not be able to request interception. There was a problem that I could not retrieve it.

(Object of the Invention) Therefore, the present invention provides dial-in numbers greater than the number of extensions in a facsimile storage and forwarding device that employs a dial-in method, assigns an extension number to the dial-in number, and uses the remaining dial-in By setting the interception function on the number, you can consciously select between direct communication with the extension and interception from the outside line, and you can always receive interception without changing the reception mode of the extension. The aim is to improve the usability and convenience of facsimile storage and forwarding devices.

(Structure of the Invention) In order to achieve the above object, the present invention connects to a plurality of facsimile terminals via a plurality of extension lines and an outside line connected to a central office exchange, and connects an external line to the central office exchange using a dial-in number. It uses a dial-in system that allows you to call an extension directly from the phone, and has a proxy reception function that receives a message from an outside line, stores it in the memory, and then sends it to a designated extension facsimile terminal, and directly connects the extension and outside line. In a facsimile storage and forwarding device equipped with a direct exchange function, etc., a number of dial-in numbers greater than the number of extensions is provided, the extension number to which calls should be received is assigned to the dial-in number, and the above-mentioned interception function is set. It is characterized by this.

Hereinafter, the present invention will be specifically explained based on examples.

1 to 3 are diagrams showing one embodiment of the present invention.

FIG. 1 is a block diagram of the facsimile storage and forwarding device 1.

The storage unit 6 stores image data of telegrams, and the storage control unit 4 controls writing and reading of the image data into the storage unit 6.

In the registration section 5, various parameters used in the facsimile storage and forwarding device W1, particularly extension function parameters related to the present invention, are set as shown in FIG.

The system control unit 7 is a CPU (Central Pr).
cessingUnit), ROM (Read
RAM (Random)
The control program for the facsimile storage and forwarding device W1 is stored in the ROM. The system control section 7 controls each section of the facsimile storage and forwarding device 1 based on the program in the ROM and the setting parameters of the registration section 5 to execute processing as the facsimile storage and forwarding device 1.

Next, the effect will be explained.

This facsimile storage and forwarding device 1 is an extension LI.

~L1. We provide a variety of communication services in response to requests from and outside *LO, ~LO. For example, extension L■, ~L1
．． Timed transmission service requested from extension facsimile terminals F+ to F1 via ! For incoming calls from LO, ~LO, direct connection to a designated extension, interception service, etc. are performed.

In particular, the facsimile storage and forwarding device W1 uses a dial-in system, and the contracted extension L1. There are more dial-in numbers (D1 numbers) than ~LI,%. Now, as shown in Figure 2, extension LI+-Ll
Assuming that the number n is 4 lines and the DI number is 5, extension numbers l" to 4" of extensions Lit to L1. are assigned to D1 numbers 1' to 4" and registered in the registration unit 5. The substitute reception function (mode) of the facsimile storage and forwarding device 1 is set in the DI number 5, and is registered in the registration unit 5. Extensions Ll to LI.

As shown in FIG. 2, a direct communication, that is, a direct connection function is set as a function for each extension L1. ~L
1. There are two types of connections: direct connection and proxy reception.

As mentioned above, this proxy reception is carried out from extension L Ir to L1.
．． This is used when the facsimile storage/exchange unit W1 cannot receive calls directly, and the facsimile storage/exchange unit W1 receives calls from outside lines LO+ to LO on an alternate basis.

Therefore, as shown in FIG. 3, when the facsimile storage and forwarding device 1 receives a call from the outside fIt, or ~ LO, (step st), the facsimile storage and forwarding device 1 receives the D from the central office exchange m (step st).
The system control unit 7 retrieves the I number (step SZ), searches the registration unit 5 based on the DI number, and checks whether the designation of the DI number designates proxy reception (see Figure 2). (Step S3). If it is not a proxy reception, the internal glands tt+ to L1 specified by the DI number. and outside line L
01 to LO, are directly connected (step S4), and returns to the initial state (step S5). At this time, the corresponding extension L
1. ~L1. If the facsimile storage and forwarding device fft cannot receive the received message due to a busy business, the facsimile storage and forwarding device fft receives it on behalf of the user.

On the other hand, when the designation by the DI number is proxy reception, the external iLO, ~LO, and the communication control unit 3 are connected, the proxy reception is performed, and the image data of the received message is stored in the storage unit 6 (step Sh ). Thereafter, the facsimile storage and forwarding device l receives the specified extension L1. -L1. , reads the message from the storage unit 6, and transmits the message to the extension L1. -L1. Send to the extension facsimile terminal F, ~Fゎ and return to the initial state (
In this way, in a dial-in type facsimile storage and forwarding device, a contract is made for more dial-in numbers than the number of extensions, a dial-in number is assigned to each extension, and the remaining dials are By setting the interception function for the in-line number, you can consciously select between direct communication with the extension and interception from the outside line, and also ensure that interception is performed without changing the form in which calls are received to the extension. be able to. As a result, the usability and convenience of the facsimile storage and forwarding device can be improved.

Note that in the above embodiment, extension L1. Although the number of L1n lines is four and the number of dial-in numbers is five, it goes without saying that the number is not limited to this.

(Effects) According to the present invention, it is possible to consciously select between direct communication with an extension line and proxy reception from an outside line, and it is possible to always have proxy reception without changing the reception form of the extension, and facsimile storage and exchange. The usability and convenience of the device can be improved.
