Description of the Related Art In general, a switching system has, as terminal information, physical information such as the accommodating position of a terminal interface and information such as an extension number and an allowable service for terminals accommodated therein, and refers to this terminal information. However, various processing such as exchange processing is performed.

By the way, the terminal information is manually registered by a maintenance person from a maintenance device when the system is constructed. Therefore, it takes a lot of time and effort to construct the system. In addition, after the system construction is completed, when it is desired to add terminals by using the vacant ports, the maintenance person must be requested to register the terminal information. If you want to temporarily add a terminal by using an empty port, you must ask a maintenance person to delete the terminal information even when you remove this terminal when you no longer need it.

And

Further, according to the present invention, the temporary storage setting information indicating whether to temporarily store the management information corresponding to the specific port in the management information storage means in association with the specific port is stored. A temporary storage setting information storage means such as a registration setting mode table and a management information deletion means such as a temporary registration information management means, and the management information deletion means detects the connection of the terminal by the terminal connection detection means. If the temporary storage setting information stored in the temporary storage setting information storage means in association with the specific port that is no longer stored indicates that the management information is temporarily stored in the management information storage means, The management information corresponding to the port is deleted from the management information storage means.

The present invention further includes management information notifying means such as terminal information notifying means, and the management information notifying means creates the management information by the management information creating means and stores the management information in the management information storing means.

3d manages the terminal information registered by the terminal information automatic registration means 23c in the terminal information table 22a when it should be temporarily registered, and extracts the corresponding multi-function digital telephone terminal DTEL. The terminal information is deleted according to the information received. The terminal information notifying unit 23e performs a process of notifying the user of the corresponding multifunctional digital telephone terminal DTEL of the extension number registered by the automatic registration of the terminal information by the terminal information automatic registration unit 23c. Is.

Next, the operation of the exchange system configured as described above will be described according to the processing procedure of the control unit 23. Note that, here, among the ports of the DSTI 14-1 installed in the slot to which the slot number is assigned “0010”, the port to which the port number “15” is assigned (hereinafter, referred to as the port of interest) has multiple functions. The main operation is to temporarily connect the digital telephone terminal DTEL.

First, at the time of constructing a communication system using the exchange system of this embodiment, terminal information about a terminal which is to be installed at that time and which is fixedly used,
Alternatively, the maintenance person registers the terminal information about the standard telephone terminal TEL in the same manner as in the past by the command input by the maintenance person. In addition, the maintenance person may use D to allow automatic registration of terminal information when the multi-function digital telephone terminal DTEL is connected.
Set the registration mode for STI14 to "automatic",
It is registered in the registration setting mode table 22b by command input. Furthermore, the maintainer is STTI13 and each DS
For each TI 14, it is set whether the automatically registered terminal information is permanent or temporary (storage mode), and is registered in the registration setting mode table 22b by command input.

When the multifunctional digital telephone terminal DTEL is connected to the port of interest, this is detected by the DSTI 14-1 and the control unit 23 is notified to that effect. Control unit 23
In the standby state as shown in FIG. 4, the terminal waits for a new connection of the terminal, removal of the terminal, or a request for exchange connection (step ST
1 to step ST3). Therefore, when the control unit 23 receives the notification from the DSTI 14-1 as described above, the step S
It is determined that a new connection of the terminal is made at T1. At this time, the control unit 23 reads the terminal information of the port (here, the port of interest) to which the terminal is connected from the terminal information table 22a (step ST4).

Subsequently, the control section 23 determines whether or not the terminal information on the port of interest has been registered in the terminal information table 22a (step ST5). If the information stored in the terminal information table 22a is in the state shown in FIG. 2, the terminal information of the target port (the terminal number is the slot number “0010” and the port number “1”).
5 "is not registered yet. Therefore, the control unit 23 reads the registration mode for the relevant port, that is, the port of interest from the registration setting mode table 22b (step ST6), and the automatic registration is designated as the registration mode. (Step ST7) Note that the port to which the multifunctional digital telephone terminal DTEL is connected is, for example, the port to which the port number “00” is given among the ports of the DSTI 14-1. If the terminal information is already registered in the registration setting mode table 22b as shown in FIG. 2, the control unit 23 returns to the standby state.

If the terminal information is not registered and automatic registration is designated as the registration mode, the control unit 2
In step 3, the terminal information automatic registration means 23c creates terminal information (step ST8). To create this terminal information,
Specifically, this is performed as follows. That is, the control unit 23 arbitrarily selects an extension number that is not currently used and sets it as the extension number of the port of interest while referring to various types of terminal information already registered in the terminal information table 22a. The service class of is set as the service class of the multifunctional digital telephone terminal connected to the port of interest.

Then, the control section 23 causes the terminal information automatic registration means 23c to store the extension number and the service class set as described above in the terminal information table 22a in association with the terminal number of the terminal connected to the port of interest. Therefore, the terminal information is registered (step ST9). Here, the extension number set for the port of interest is "401
2 ", and if the service class related to the multifunctional digital telephone terminal connected to the target port is" class C ", the state in the terminal information table 22a changes from the state of FIG. 2 to the state of FIG. It will be.

Next, the control section 23 reads the storage mode relating to the port of interest from the registration setting mode table 22b (step ST10), and "temporarily stores" as the storage mode.
Is determined (step ST1).
1). If "temporary storage" is designated for the slot number "0010" of the slot in which the DSTI 14-1 is mounted, as shown in FIG.
To determine that "temporary storage" is specified as the storage mode for the port of interest, which is the port provided in I14-1, and to indicate that the terminal information corresponding to the port of interest has been temporarily registered. As shown in FIG. 5, the flag is turned on (step ST12). When the terminal information is automatically registered for the port for which "permanent storage" is specified as the storage mode, the control unit 23 sets the flag to OFF.
Leave as is. Steps ST10 to S above
The processing of T12 is performed by the temporary registration information management means 23d.

Upon completion of various registrations as described above, the control unit 23 uses the terminal information notifying means 23e to notify the user of the multifunctional digital telephone terminal DTEL connected to the target port of the extension number, for example, the multifunctional digital signal. This is performed by means such as displaying on the display of the telephone terminal DTEL (step ST13). After that, the control unit 23 finishes the process and returns to the standby state.

Now, each line interface card 12,
When a connection request is detected by either the STTI 13 or each DSTI 14 and is notified to the control unit 23, the control unit 23 determines in step ST3 that a connection request has occurred. Then, at this time, the control unit 23 reads the terminal information of the connection request source and the requested connection destination from the terminal information table 22a (step ST14),
From the result, it is determined whether or not the terminal information of at least one of the request source and the connection destination is not registered in the terminal information table 22a (step ST15).

Here, if both the terminal information of the request source and the terminal information of the connection destination can be read, the control unit 23 determines that the registration has been completed, and with this, the authentication for the connection request is OK. At this time, the control unit 23 uses the exchange control means 23a to perform the exchange process in the same procedure as that conventionally performed (step ST1).
6). Therefore, after the multifunctional digital telephone terminal DTEL is connected to the target port and the terminal information is automatically registered to the target port as described above, the extension number "4012" set for the target port is connected to the target port. When the connection request designated as is made, the control unit 23 performs the exchange process with the authentication for this connection request as OK. Alternatively, as described above, after the multifunctional digital telephone terminal DTEL is connected to the attention port and the terminal information is automatically registered to the attention port, a connection request is made from the multifunctional digital telephone terminal DTEL connected to the attention port. Then, the control unit 23 performs the exchange process with the authentication for this connection request as OK.

On the other hand, if one of the request source terminal information and the connection destination terminal information cannot be read normally, the control unit 23
Determines that it is unregistered, and with this, authentication for the connection request is set to NG. At this time, the control unit 23
For example, a request rejection process (step ST17) such as outputting a predetermined tone signal for notifying a dial error to the request source of the connection request is performed, and no exchange process is performed.
Therefore, as described above, the extension number "40" is set before the multifunctional digital telephone terminal DTEL is connected to the target port.
Even if a connection request specifying 12 "as a connection destination is made, the control unit 23 rejects this connection request and does not perform the exchange process.

By the way, when the multifunctional digital telephone terminal DTEL connected to the port of interest becomes unnecessary and is removed from the port of interest, this is detected by the DSTI 14-1,
This is notified to the control unit 23. Then the control unit 2
3 determines that the terminal has been removed in step ST2. Then, at this time, the control unit 23 reads the terminal information of the port (here, the port of interest) from which the terminal is removed from the terminal information table 22a (step ST
18) Then, it is determined whether or not the flag attached to this terminal information is ON (step ST19).

Since the flag attached to the terminal information registered for the port of interest is ON,
The control unit 23 deletes the terminal information registered for the port of interest from the terminal information table 22a by the temporary registration information management unit 23d (step ST20). If the flag attached to the terminal information is not ON, the control unit 23 does not delete the terminal information. The above is the normal operation for realizing an actual communication system.

Next, a case will be described in which the software describing the operation of the control unit 23 is tested at the development stage or the manufacturing stage of the exchange system of this embodiment.
At this time, the unique device simulator 8 is connected to the central controller 2 via the Ethernet interface 15 as shown in FIG. Further, a terminal simulator 9 is connected to the unique device simulator 8.

The unique device simulator 8 includes a switch unit 1
A switch simulating unit 81 for simulatingly implementing the function of No. 1, a line interface simulating unit 82 for simulatingly implementing the function of the line interface card 12, and a terminal interface simulating unit 83 for simulatingly implementing the functions of the STTI 13 and DSTI 14. It has and simulates the function of the exchange-specific device 1. The terminal simulator 9 simulates the functions of the standard telephone terminal TEL and the multifunction digital telephone terminal DTEL.

The unique device simulator 8 and the terminal simulator 9 are realized by a general-purpose computer such as a workstation or a personal computer, or an application in a one-board computer or the like.

At this time, the central control unit 2 performs substantially the same operation as the above-mentioned normal operation according to various data given from the unique device simulator 8. This allows
The software describing the operation of the control unit 23 can be tested by verifying whether or not the central control device 2 performs appropriate processing on arbitrary data from the unique device simulator 8.

However, in the central control unit 2 of the present embodiment, the processing when a connection request is generated is slightly different from the above-mentioned normal operation. That is, as shown in FIG. 7, the control unit 23 of the central controller 2 determines whether at least one of the request source terminal information and the connection destination terminal information is not registered in the terminal information table 22a (step S).
When it is determined that at least one of the request source terminal information and the connection destination terminal information is unregistered in the terminal information table 22a by performing T15), the unregistered terminal information is created according to a predetermined logic. To do. Specifically, assuming that the terminal information of the connection destination is not registered, if a connection request is made with the terminal of the extension number "4321" as the connection destination, the above "4321" is set as the extension number. If the request source is the multi-function digital telephone terminal DTEL, the terminal type is also set to the multi-function digital telephone terminal DTEL, and the port number does not have much meaning in the case of the simulator, so it is arbitrarily selected from the table according to the terminal type. .

Subsequently, the control unit 23 registers the terminal information created as described above in the terminal information table 22a,
In step ST16, the exchange process is performed with reference to the terminal information registered in the terminal information table 22a as described above.

As described above, according to the present embodiment, with respect to the port provided in the DSTI 14 installed in the slot in which "automatic" is set as the registration mode, a multifunctional digital telephone terminal is simply connected thereto. Then, the terminal information is automatically created and registered in the terminal information table 22a.

Therefore, by simply connecting the multifunctional digital telephone terminal, the multifunctional digital telephone terminal can make and receive a call and can make a call. This eliminates the need for a maintenance person to register the terminal information each time when adding or temporarily installing a multi-function digital telephone terminal. It is possible to construct a convenient communication system that can be easily performed. Also, if the number of terminals that can be used on the exchange system is limited, setting the minimum terminal information and automatically setting the rest will save resources.

According to the present embodiment, it is possible to arbitrarily set whether the terminal information is automatically registered or command registered for each port. Similarly, it is possible to arbitrarily set whether the terminal information once registered for each port is temporarily stored or permanently stored.
With these, flexible operation according to the communication system to be constructed is possible, and the versatility is high.

Further, according to this embodiment, the extension number set by automatic registration is notified to the user of the multifunctional digital telephone terminal to which the extension number is assigned, so that the setting of the terminal information is completed, The user can easily and surely know the set extension number.

Further, according to this embodiment, the central controller 2
When the unique device simulator 8 and the terminal simulator 9 are connected to each other and the software describing the operation of the control unit 23 is tested, the request source and connection destination terminal information of the connection request given from the unique device simulator 8 Even if not registered, since the exchange process is performed after automatically registering the terminal information related to the request source and the connection destination, there is no need to register the terminal information in advance for the above test, and the unique device In the simulator 8 and the terminal simulator 9, the connection request may be generated without considering the registration status of the terminal information in the central control unit 2 at all, so that the time and effort required for the above test can be greatly saved. As a result, it becomes very efficient when developing a new software service, and the service development cycle corresponding to various user needs can be shortened.

The present invention is not limited to the above embodiment. For example, in the above embodiment, some of the plurality of ports are set as ports (specific ports) that allow automatic registration of terminal information, but all existing ports may be specified ports. Moreover, although a specific port among a plurality of ports can be arbitrarily set, it may be fixedly set.

In the above embodiment, only the port for the multi-function digital telephone terminal DTEL is set as the specific port and the terminal information is automatically registered. However, the terminal information about the port for the standard telephone terminal TEL can also be automatically registered. You may do it. However, in this case, since the STTI 13 does not normally have a function of detecting the connection of the standard telephone terminal TEL, the STTI 13 is improved to improve the standard telephone terminal TE.
It is necessary to be able to detect the connection of L. In order to avoid this, the connection of the standard telephone terminal may be detected in response to the fact that the standard telephone terminal TEL, which does not know that it is connected, has gone off-hook. At this time, the terminal information is not set until the standard telephone terminal TEL is actually connected and before the off-hook is made.
This can be easily prevented by taking measures such as prescribing a work procedure so that the EL is once hooked off. Further, since the standard telephone terminal TEL usually does not have a display, it cannot notify the extension number by display, but it can be easily substituted by a voice message or the like.

In the above embodiment, the connection of the terminal is detected and the terminal information is registered for each port. However, for example, the new insertion of the interface card is detected, and the new interface card is inserted. At this time, the terminals may be regarded as connected to all the ports of the interface card, and the terminal information of each port may be automatically registered.

Further, it is possible to arbitrarily set the rules for creating the terminal information when automatically registering the terminal information. That is, for example, in the above embodiment, when the terminal information is automatically registered, the service class is set to the service class for automatic registration. However, the service class is set for each terminal type, each port, or each interface card. May be changed. Specifically, the service class for the multifunction digital telephone terminal is set at the port for the multifunction digital telephone terminal, and the service class for the standard telephone terminal is set at the port for the standard telephone terminal. In addition, various modifications can be made without departing from the spirit of the present invention.

According to the present invention, exchange means such as a switch unit for arbitrarily exchange-connecting a plurality of ports and predetermined management information such as terminal information corresponding to each of the plurality of ports are stored.
