Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic exchange used in a premises such as offices and business establishments.

[0002]

2. Description of the Related Art In general, a private branch exchange accommodates a plurality of extension lines and office lines, and exchanges between these extension lines and between extension lines and station lines are controlled according to an extension number registration table in a main memory. . In other words, the extension number registration table stores extension numbers (logical port numbers) corresponding to the physical port numbers fixedly assigned to the plurality of extension terminal connection ports provided in the exchange main body. Therefore, when an incoming call occurs, the exchange retrieves the extension of the physical port number corresponding to the extension number of the called party based on the extension number registration table and performs the incoming call process.

When an extension telephone is added or relocated in this type of private branch exchange, for example, it is performed as follows. That is, first, an extension telephone is connected to an unused port. It is assumed that the extension number of this port has not been assigned yet. Then, the central control unit of the exchange is accessed by using a specific management terminal attached to the exchange to request the central control unit to register the extension number. Next, when the person in charge inputs an extension number by associating with the unused port by a key operation or the like, the extension number registration table in the main storage unit controls the extension terminal connection port by the control of the central control unit. The input extension number is registered in the storage area corresponding to the physical port number.

[0004]

As described above, the extension number registration processing associated with the extension of extension telephones, for example, is a function for the maintenance personnel of the exchange to register the extension number in the extension port number registration table. It is carried out by using a specific management terminal having the above. For this reason, when it is necessary to register the extension number, the registration applicant has to bother the maintenance staff in another place for the registration, which is troublesome. Further, if there is no maintenance staff who can operate the management terminal, the extension number cannot be registered. Further, generally, the processing using the management terminal requires a complicated operation procedure such as command input, so that the work related to the extension number registration processing is very troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic exchange capable of easily performing extension number registration processing associated with extension or relocation of extension terminals without using a specific management terminal. .

[0006]

To achieve the above object, the present invention accommodates at least one station line and a plurality of extensions to which a plurality of extension terminals including at least one specific extension terminal are connected. An electronic exchange having a memory table in which an extension number is registered corresponding to each of the above-mentioned extensions, and having a function of performing a call reception process by retrieving an extension of a call destination based on the registered contents of the memory table when an incoming call occurs. When a connection request to the specific extension terminal is received from an unregistered extension terminal connected to an extension whose extension number is not registered, the specific extension terminal is called and the connection request is sent to the unregistered extension terminal. A connection means is provided for connecting with an extension terminal to enable transfer of extension number information desired to be registered from the unregistered extension terminal to the specific extension terminal, If the registration request extension is sent from the extension terminal comprises a registration request detecting means for detecting this, the extension number registration control unit. Then, when the arrival of the registration request is detected by the registration request detection means, by the extension number registration control means, based on the extension number information of the unregistered extension terminal sent from the specific extension terminal together with the registration request, The extension number is registered in the memory table in association with the unregistered extension number.

[0007]

As a result, according to the present invention, when a connection request from an unregistered extension terminal connected to an extension whose extension number is not registered to a predetermined specific extension terminal, the specific extension terminal is connected. A call is made to the extension terminal that has sent the connection request and the speaker of the unregistered extension terminal notifies the speaker of the specified extension terminal of the extension number to be registered. It becomes possible to do. That is, a speaker of an unregistered extension terminal can make a call to a specific extension terminal from a self-registered extension terminal, which is confident that it cannot be used (call origination / termination), so that the extension terminal can use its own extension terminal. A number registration request can be sent to a specific extension terminal. Therefore, the registration request can be made easier and faster than in the conventional case in which the registration request must be sent by searching for another registered extension terminal and handing a memo etc. separately to the person in charge of maintenance. Can be told. Further, when the speaker of the specific extension terminal that has received the notification inputs a request for registering the extension number from the specific extension terminal to the memory table and the notified extension number, the input extension The extension number is stored in the memory table in association with the extension number which is not registered. Therefore, the extension number can be registered in the exchange easily from a specific extension terminal without using a specific management terminal that requires a complicated operation procedure. For example, if the above-mentioned specific extension terminal is set as a station line repeater that seems to be always stationed by an exchange operator, problems such as postponement of registration due to the absence of a registration processor can be avoided, which is particularly effective. .

1 is a circuit block diagram showing the configuration of a private branch exchange according to an embodiment of the present invention. In the figure, this private branch exchange has a switching circuit 1 and a control circuit 2.
A memory circuit 3, extension circuits LC1 to LCn, station line circuits TRK1 to TRKm, and a control data bus line 4 for transmitting various control signals between these circuits and the control circuit 2. There is.

Each of the extension circuits LC1 to LCn has an extension L1.
To Ln are connected to extension telephones EKT1 to EKTn, and office lines SL1 to SLm are connected to office line circuits TRK1 to TRKm, respectively. Extension circuit LC
1 to LCn and station line circuits TRK1 to TRKm are connected to the extension lines L1 to Ln and the station line S, respectively.
While monitoring the states of L1 to SLm, control information is exchanged with the central control circuit 2 to perform predetermined line control.

Under the control of the central control circuit 2, the exchange circuit 1 includes the extension circuits LC1 to LCn and the office line circuits TRK1 to TRK1.
Switching connection with the TRKm is performed, and switching connection with the extension circuits LC1 to LCn is performed.

A relay stand 5 is connected to the exchange circuit 1 via an extension circuit LC. The relay stand 5 gives to the control circuit 2 an instruction such as an intermediary to an extension for an incoming call from a station line.

The storage circuit 3, as shown in FIG. 3, stores an extension number (logical port number) for each physical port number fixedly assigned to each of a plurality of extension terminal connection ports of the exchange main body. It has a registration table 31. For a physical port number for which an extension number is not registered in the table, it indicates that the extension of that physical port number is in an unused state, and the call is made from the extension in this state or is received by the extension. You can't usually do that.

The control circuit 2 is provided with, for example, a microcomputer as a main control unit, and in addition to ordinary control means such as exchange control relating to incoming and outgoing calls, relay console connection control means 21 and extension number registration control means. 22 and 22.
The relay stand connection control means 21 calls the relay stand 5 when a special number requesting a connection to the relay stand 5 is input from an extension telephone connected to a port whose extension number is not registered, When the relay stand 5 responds, the extension telephone which has made the connection request is connected to enable the call. The extension number registration control means 22 receives the extension number from the relay stand 5 when the extension number registration table 31 is requested to register the extension number, and the extension number is followed by information indicating the extension number. The extension number represented by the number information is stored in the extension number registration table 31 in association with the physical port number of the port whose extension number is not registered. A maintenance terminal 6 for maintenance and management is connected to the control circuit 2.

Next, the procedure for registering an extension number in the private branch exchange configured as described above will be described. Now, suppose that the physical port number of the port accommodating the extension L3 is "003" and that the extension L3 is in an unused state. In this state, it is assumed that the user of the extension telephone connects the extension telephone to the extension L3 and then calls the relay stand 5 from the extension telephone to request the extension number registration process for the extension telephone. At this time, the registration requester dials in the relay stand calling special number for requesting the calling of the relay stand 5. Then, the dial signal corresponding to the special number for calling the relay stand is detected by the extension circuit, and the control signal representing the special number is transferred from the extension circuit to the control circuit 2.

When the control circuit 2 detects the arrival of the relay stand calling special number from the extension L3 in step 301 of FIG. 3, it checks the state of the relay stand 5, and if the relay stand 5 is empty, the control stand 2 is concerned. In step 302, the extension circuit LC is instructed to send an incoming signal to start calling the relay stand 5. Then, an incoming signal is sent from the extension circuit LC to the relay stand 5, thereby calling the replacement person of the relay stand 5. The control circuit 2 monitors in step 303 whether or not a response is made in the relay stand 5. Then, when the exchange operator responds to the call, the control circuit 2 connects the relay stand 5 and the extension telephone which has made the call request in step 304 to enable the call.

When a call is established with the relay stand 5, the registration requester informs the exchange operator of the extension number (for example, "300") desired to be registered. The exchange operator, who has received the extension number declaration from the registration requester, keeps the call with the registration requester and requests the execution of the extension number registration process to the control circuit 2 of the exchange. The extension number registration special number to be represented and the extension number declared above are dialed from the relay stand 5 subsequently. Then, the dial signal corresponding to the special number and the extension number which have been dialed are detected by the extension circuit LC, and the information representing the special number is transferred from the extension circuit LC to the control circuit 2. When the control circuit 2 detects the arrival of the extension number registration special number from the relay stand 5 in step 401 of FIG. 4, the control circuit 2 receives the extension number that arrives together with the extension number in step 402, and also in step 403, the extension number. Is already used, and whether the extension number does not deviate from the range of extension numbers permitted on the system, and it is determined whether or not the extension number can be registered. As a result, when it is determined that the extension number can be registered, the control circuit 2 relays the relay to the storage area corresponding to the physical port number of the extension L3, that is, "003" in the extension number registration table in step 404. Write the extension number "300" sent from the stand 5. When the writing is completed, the control circuit 2 sends a notification that the registration of the extension number in the extension number registration table 31 is completed to the relay stand 5 in step 405. This notification may be made by means of, for example, a tone or voice, or by lighting or displaying a message when the relay stand 5 has a display function such as an LED or a liquid crystal display (LCD).

Upon receipt of the notification of the completion of registration from the control circuit 2 in this manner, the exchange operator reports to the registration requester by telephone that the extension number has been registered and ends the call. After that, the telephone of the extension L3 is registered as an extension telephone of the private branch exchange, and the extension number is set to "300", and the incoming call processing is performed. If it is determined that the extension number sent from the relay stand 5 is unregisterable as a result of the determination in step 403, the control circuit 2 determines in step 406 that the extension number cannot be registered in the relay stand 5. Is notified and the process ends.

As described above, according to this embodiment, when assigning an extension number to an extension whose registration number is not registered, the registration requester first assigns a special number from the extension telephone connected to the extension whose registration number is not registered. By inputting, the exchange requester requests a connection to the relay stand 5 which is expected to be always stationed, and when a call is established with this relay stand 5, the registration requester is Request the extension number registration process and declare the extension number to be registered. Then, if the exchange operator who received this declaration inputs the special number requesting registration of the extension number from the relay stand 5 and the extension number declared by the registration requester, this is input. The extension number is stored in the extension number registration table 31 in association with the physical port number of the extension that has sent the connection request. That is, a registration requester who intends to register an extension number with an extension or the like makes a connection request from the extended extension telephone to the relay stand 5, and after connection, declares a desired extension number to a replacement operator. As a result, the extension number can be registered through the exchange operator. This eliminates the need to request maintenance personnel from other locations to register, and also eliminates the need to use a management terminal that requires complicated operation procedures. The registration process can be easily performed. Further, as described above, since the exchange handler is supposed to be stationed at all times during the daytime, it is possible to avoid problems such as postponement of registration due to the absence of a registration processor as in the past.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the registration requester requests the exchange operator of the relay stand 5 to register the extension number, and then the caller is in a call state until the registration result is returned by the exchange operator. Alternatively, the call may be temporarily disconnected after the registration request, and the registration requester may be called from the relay stand 5 and returned when the registration result is returned. Further, in the above-described embodiment, when the extension number to be registered is unregisterable, the control circuit 2 notifies that registration is impossible and ends the processing as it is. However, the notification that registration is impossible is received. The series of registration processes may be continuously repeated according to another extension number input from the registration requester through the exchange operator. Further, in the above embodiment, the extension number is notified from the registration requester to the exchange handler by telephone, but this may be done by a predetermined special number dial or function key operation. Regarding the notification of the registration processing result from the exchange operator to the registration requester, in addition to the call, if the tone or voice synthesis or the extension telephone has a display function such as LED or LCD, the result is used. You may make it notify. Further, in the above embodiment, the registration request destination from the extension telephone whose extension number is not registered is set to the relay stand 5, but this may be a predetermined specific extension terminal. Further, in the above embodiment,
When an extension telephone with an unregistered extension number receives a special number requesting a connection to the relay stand 5, the two are connected to each other. When the call is made, the extension telephone may be connected to the relay stand 5. In addition, various modifications can be made without departing from the scope of the present invention.
