Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic exchange having a function of receiving a dial pulse as a selection signal and executing outgoing exchange control.

[0002]

2. Description of the Related Art Conventionally, some exchanges of this type are provided with an in-call service function such as a transfer service. This in-call service function performs so-called one-dial hooking, for example, in which a speaker dials a dial pulse type "1" during a call, and this operation causes a disconnection pulse (hooking pulse) sent through an extension line by a switch. It is executed by detecting. Therefore, the in-call service can be easily received from the dial pulse type standard telephone.

[0003]

However, this type of conventional exchange is configured to unconditionally execute the in-communication service when a hooking pulse arrives from the extension telephone during a call. Therefore, for example, when a curl cord touches a hook button during a call, an erroneous hooking pulse is generated, or the user mistakenly turns the dial, which causes a pulse equivalent to the hooking pulse. There is a problem in that the exchange executes unnecessary call service that the speaker does not want in response to these pulses.

The present invention has been made in view of the above circumstances, and an object of the present invention is to perform unnecessary call service even if a hooking pulse is erroneously generated from an extension telephone during a call. It is to provide an electronic exchange that can prevent such a situation.

Another object of the present invention is to individually regulate the execution processing of the in-call service for each extension to be accommodated, whereby a more versatile electronic exchange depending on the usage of each extension terminal. To provide.

[0006]

In order to achieve the above object, the present invention receives a dial pulse sent as a selection signal from an extension terminal at the time of making a call from the extension terminal to perform a predetermined call origination control and at the same time during a call. When a disconnection pulse is sent from the extension terminal to request execution processing of a predetermined in-call service, it is accommodated in an electronic exchange equipped with a one-dial hooking function for executing the requested in-call service execution processing. Storage means for storing information indicating whether or not to permit execution processing of the in-call service by the one dial hooking function for all extensions.
In response to a predetermined change operation, a change control means for changing the information stored in the storage means, and an extension terminal in a call, when a request to execute a service during a call due to the disconnection pulse arrives, A means for determining whether or not to execute the above-mentioned service during a call based on the information stored in the storage means, and processing it.

According to another aspect of the present invention, when an extension terminal makes a call, a dial pulse sent from the extension terminal as a selection signal is received to perform a predetermined call control, and the extension terminal in the call can perform a predetermined in-call service. In the electronic exchange equipped with the one-dial hooking function for executing the requested in-call service when the disconnection pulse requesting the execution processing is sent, the one-dial hooking function for each extension accommodated. Storage means for storing information indicating whether or not to permit execution processing of the in-call service by means of a change control means for changing the information stored in the storage means in response to a predetermined change operation. And when an extension terminal in a call receives a request to execute a service during a call due to the disconnection pulse, based on the information stored in the storage means. The inner wire and to and means for processing to determine whether to execute processing of the call in the service.

[0008]

As a result, according to the present invention, when the disconnection pulse arrives from the extension terminal during a call, whether the execution process of the requested service during the call is in the permitted state or the prohibited state is stored in the storage means. It is determined based on the stored contents, and when it is determined that the execution processing of the in-call service is in the permitted state, the execution processing of the in-call service is performed,
On the other hand, when it is determined that the execution process of the in-call service is in the restricted state, the execution process of the in-call service is prohibited. Therefore, if you want to prohibit the execution of in-call service due to hooking, the user of the extension terminal must register in advance that the one-dial hooking function should be restricted. Even if you end up dialing or dialing "1", the service during the call is not executed.

According to another aspect of the present invention, by storing information indicating whether or not the execution processing of the in-call service is permitted for each extension accommodated in the exchange, it is desired to use the one-dial hooking function. Person and a speaker who do not want to use can be accommodated in the same system according to their wishes. This makes it possible to provide a more versatile private branch exchange according to the usage status of each extension terminal.

Km is exchange-connected with each other, and the extension circuits LC1 to LCn are exchange-connected with each other.

The memory circuit 3 is composed of (a), (b) and (c) of FIG.
System data registration table 3
1, an individual data registration table 32, and a call processing data registration table 33. The system data registration table 31 stores, as system data common to each extension, a flag indicating permission (“00”) / regulation (“01”) of one-dial hooking. Individual data registration table 32 and call processing data registration table 33
Stores a flag indicating permission (“00”) / restriction (“01”) of one-dial hooking for each of the extensions L1 to Ln. Of these, the above-mentioned data 31, Required individual data is registered when the registration of 32 is changed and the exchange is started up (initialization). A specific value "FF" is stored for the extension for which individual data is not registered in the individual data registration table 32.

The control circuit 2 has a one-dial hooking change control means 21 and a one-dial hooking execution control means 22 in addition to ordinary control means such as exchange control relating to incoming and outgoing calls. When a system data change request is input from the maintenance terminal 5, the one-dial hooking change control means 21 responds to the information indicating the change content that comes with the change request, according to the system data registration table 31 and the call processing. A flag "00" or "01" indicating permission / restriction of one-dial hooking is stored in all storage areas of the data registration table. Further, when a request for changing individual data is input from the maintenance terminal 5, the one-dial hooking change control means 21 controls the individual data registration table 32 and the individual data registration table 32 according to the information indicating the contents of the change coming with the change request. A flag "00" or "01" indicating permission / restriction of one-dial hooking is stored in each corresponding storage area of the call processing data registration table 33. Further, the one-dial hooking change control means 21 refers to the registered contents of the system data registration table 31 and the individual data registration table 32 at the time of startup of the exchange to permit the one-dial hooking to the call processing data registration table 33. /
The flag "00" or "01" indicating the regulation is written. At this time, the flag written in the call processing data registration table 33 has priority for individual data, and is referred to as system data when there is no individual data (when "FF").

One dial hooking execution control means 22
When a disconnection pulse due to one-dial hooking arrives from the extension telephone during a call, the one-dial hooking is enabled or restricted for the extension based on the registered contents of the call processing data registration table 33. If it is in the permitted state, the requested in-call service is executed, and in the prohibited state, the execution of the in-call service is prohibited.

Next, the operation of the private branch exchange configured as described above will be described. Now, for example, it is assumed that the maintenance personnel of the exchange inputs from the maintenance terminal 5 a system data change request and, following this change request, information indicating the change contents, that is, data indicating permission / restriction of one-dial hooking. When the control circuit 2 detects a system data change request in step 3a of FIG. 3, it determines in subsequent step 3b whether the information indicating the change content is "permitted" or "restricted". As a result, when the information indicating the changed contents indicates "permitted", the control circuit 2 causes the step 3c.
Then, a flag "00" for permitting one-dial hooking is written in all the storage areas of the system data registration table 31 and the call processing data registration table 33. On the other hand, when the result of the above determination indicates that the information indicating the changed contents indicates "restriction", the control circuit 2 causes the step 3d
Then, a flag "01" for restricting one-dial hooking is written in all the storage areas of the system data registration table 31 and the call processing data registration table 33. When the change of the system data is completed in this way, the control circuit 2 clears (to "FF") all the registered contents in the individual data registration table 32 in step 3e.

On the other hand, the maintenance personnel of the exchange uses the maintenance terminal 5 to indicate a change request for individual data relating to an arbitrary extension and information indicating the change following this change request, that is, permission / regulation of one-dial hooking. Suppose you have entered data. When the control circuit 2 detects a request for changing individual data in step 4a of FIG. 3B, it determines in subsequent step 4b whether the information indicating the change is "permitted" or "restricted". As a result, when the information indicating the changed contents indicates "permitted", the control circuit 2 stores the individual data registration table 32 and the call processing data registration table 33 corresponding to the corresponding extensions in step 4c. Write a flag "00" indicating that one-dial hooking is permitted in the area. On the other hand, when the result of the above determination indicates that the information indicating the changed content indicates "restriction", the control circuit 2 corresponds to the corresponding extension of the individual data registration table 32 and the call processing data registration table 33 in step 4d. Write the flag "01" to the effect that the one-dial hooking is restricted in the storage area.

Here, a procedure for generating call processing data from system data and individual data will be described.
That is, the control circuit 2 first refers to the individual data registration table 32 in step 5a of FIG. 5, and first determines whether or not data other than the specific value "FF" is registered in the storage area corresponding to the extension L1. To do. As a result, the extension L
Assuming that "00" or "01" has been registered as individual data in the storage area corresponding to 1, the control circuit 2 reads this individual data in step 5b, and at the same time calls the individual data for call processing data in step 5c. Write to the storage area corresponding to the extension L1 of the registration table 33. On the other hand, as a result of the above determination, when the specific value "FF" is registered in the storage area corresponding to the extension L1, the control circuit 2 at step 5d reads the system data ("00" or "01") from the system data registration table 31. "), The system data is written in the storage area corresponding to the extension L1 of the call processing data registration table 33 in step 5c.
When the initialization of the extension L1 is completed in this way, the control circuit 2 repeats the above procedure until the initialization of all lines is completed.

Now, in such a state, it is assumed that, for example, the speaker mistakenly performs hooking operation or dial operation on the extension telephone P1 in a talking state. Then, a hooking pulse corresponding to the hooking operation or the dial operation is sent to the exchange through the extension line. In the exchange, when the arrival of this hooking pulse is detected by the extension circuit LC1, the fact is notified to the control circuit 2
Will be notified to. At this time, the control circuit 2 monitors the arrival of the hooking pulse from the extension telephone P1 in step 6a of FIG. 6, and when the hooking pulse arrives, the control circuit 2 determines in step 6b whether the extension L1 is busy. To do. As a result, when it is determined that the extension L1 is busy, the control circuit 2 subsequently determines in step 6c whether the one-dial hooking for the extension L1 is "permitted" or "prohibited". judge. This determination is made by checking whether the stored content corresponding to the extension L1 in the call processing data registration table 33 is "00" or "01". As a result of this determination, the extension L1
If the stored content corresponding to "00" is "00", the control circuit 2 determines that the one-dial hooking for the extension L1 is in the permitted state, and executes the required in-call service in step 6d. Perform hooking process. However, if the stored content corresponding to the extension L1 is "01", the control circuit 2 determines that the one-dial hooking for the extension L1 is in the restricted state, and ends the processing. When it is determined that the extension L1 is not in a call as a result of the determination in step 6b, the control circuit 2 performs dial analysis for call control in step 6e.

As described above, according to this embodiment, the system data registration table 31 in which a flag indicating permission or restriction of one-dial hooking is stored as the system data common to all the extension lines to be accommodated, and each extension line L1 to be accommodated. L
An individual data registration table 32 in which a flag indicating permission or restriction of one-dial hooking is stored in association with each n, and an extension in which the individual data is registered in the table 32 according to the stored contents of each of these tables For each extension, and for the extension whose individual data is not registered in the table 32, the call processing data registration table 33 in which the system data is read out and stored respectively, is prepared, and the extension telephone which is talking in this state is prepared. When a hooking pulse comes from the call processing data registration table 33, it is determined whether the one-dial hooking for the extension telephone is in the permitted state or the regulated state based on the stored contents of the call processing data registration table 33. If there is a call, the above service during call is executed. Since the execution process of the screw is prohibited, the user of each extension phone can erroneously make a mistake during a call after that by registering the restriction of one-dial hooking for the extension phone of his / her own extension phone in advance through the maintenance staff etc. Even if "1" is dialed or a hooking operation is performed, it is possible to prevent the problem that the in-call service is unconditionally executed as in the conventional case.

For a speaker who wants to use the one-dial hooking function, if the speaker has previously registered the one-dial hooking permission by associating it with his / her own extension telephone, the talker will continue to talk as usual. The desired in-call service can be received by hooking operation or dialing "1". Further, the permission / registration registration of the one-dial hooking can be arbitrarily changed using the maintenance terminal, so that it is possible to flexibly deal with a change in the usage status of the extension telephone of the speaker.

The present invention is not limited to the above embodiment. For example, in the above embodiment, a call processing data registration table 33 in which one dial hooking permission / restriction data is stored is provided for each extension, and permission / restriction of a service during a call is determined based on the stored contents of the table 33. However, this is configured with only a memory table in which system data is registered,
Permission for one-dial hooking for all extensions /
The regulation may be determined and processed. In addition, the data structure of the memory table, the configuration of the private branch exchange, and the like can be variously modified and implemented without departing from the scope of the present invention.

[0023]

As described in detail above, according to the present invention, a storage means for storing in advance information indicating whether or not to permit execution processing of a service during a call by one-dial hooking is provided, and a call is made in this state. When a disconnection pulse requesting execution of the in-call service is received from the internal extension terminal, it is determined whether or not to execute the in-call service based on the stored contents of the storage means. Therefore, even if a hooking pulse is erroneously generated from the extension terminal during a call, it is possible to provide an electronic exchange that can prevent unnecessary service during a call from being executed. .

According to another aspect of the present invention, since information indicating permission / restriction of the one-dial hooking can be set for each extension to be accommodated, it is possible to flexibly respond to the usage status of each extension terminal. It is possible to provide an exchange with high serviceability.
