Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interrupt prohibition registration cancellation method, and more particularly to an interrupt prohibition registration cancellation method in an automatic private branch exchange having an interrupt function.

Generally, in an automatic private branch exchange, when an incoming office line call occurs on a busy extension, the office line relay board interrupts the busy extension and announces the occurrence of the office line incoming call.

There may also be cases where a call is interrupted for a test. However, in recent years, the types of communications carried out via automatic private branch exchanges have diversified from telephone calls to facsimiles, data communications, and the like. Among these communication types, such as facsimile or data communication, interference noise added by receiving an interrupt connection may damage the communication information, so interrupt connection is prohibited for this type of communication. Must be. FIG. 1 is an example of a relay system diagram of an electronic private branch exchange equipped with a conventional interrupt prohibition means.

In FIG. 1, the storage device M in the central processing system CP includes:
There is an interrupt qualification section OF for each extension, and before operating the switchboard, the maintenance person sets the interrupt qualification section OF to 1 or 0 from the maintenance panel MP, typewriter TYP, etc. depending on the presence or absence of the interrupt prohibition qualification for each extension. . In FIG. 1, extension A has an interrupt-disabled status and the corresponding interrupt-qualified field OF is set to 1, and extension B does not have an interrupt-disabled status and its corresponding interrupt-qualified field OF is set to 0. It is set. Extension A is trunk T
, and is connected by route 1 of the network NW, and during a call, an interruption is required from the office line relay stand ATT. The central processing system CP receives an interrupt request for extension A from the central office relay board ATT, learns that the interrupt qualification section OF of extension A in the storage device M is 1, and determines that extension A is not qualified for interrupts. It recognizes that there is a connection, does not execute an interrupt connection, and displays an interrupt-disabled display to the central office line relay stand ATT. Next, extension B is connected to trunk L.
is connected by route 2 of network NW and during a call,
An interrupt is required from the central office line relay stand ATT. central processing system C
As mentioned above, P knows that the interrupt qualification part OF of extension B in the storage device M is 0, recognizes that extension B does not have interrupt prohibition qualification, and creates route 3 in the network NW. settings and complete the interrupt connection from the central office line relay stand ATT. As is clear from the above explanation, according to the conventional system, the presence or absence of interrupt prohibition qualification is fixed for each extension.

However, according to recent technology, the same extension line can perform a variety of communications, and in such cases, the necessity of inhibiting interruptions changes each time depending on the type of communication. It is impossible to change the interrupt prohibition qualification of each extension as described above using the conventional method of setting the interrupt prohibition qualification from the maintenance panel MP, typewriter TYP, or the like. An object of the present invention is to eliminate the drawbacks of the conventional system as described above, and to realize a flexible interrupt prohibition qualification setting means that can sufficiently cope with the diversification and complexity of communication forms of automatic private branch exchange extension lines.

In order to achieve this object, the present invention provides an interrupt prohibition qualification that prohibits interruptions from other calls during a call on an extension telephone by a registration operation from the extension telephone in an automatic private branch exchange having an interrupt function. and a means for resolving the interrupt prohibition qualification when the extension telephone is restored after the end of the call, and means for resolving the interrupt prohibition qualification from another call to the extension telephone that has entered the talking state after registering the interrupt prohibition qualification. The feature is that interruptions are prohibited, and the qualification to prohibit interruptions is automatically canceled after the call ends.

An embodiment of the present invention will be described below with reference to FIG.

In Fig. 2, the electronic on-premises communication≠In the storage device M in the central processing system CP of the back machine, there is an interrupt qualification section OF for each extension, as in Fig. 1, but each extension has its own settings. shall be carried out as necessary. Now, extension A makes a call to perform communication via trunk T, which requires interruption prohibition. Extension A is connected to register trunk ORT via path 1 of network NW in a well-known manner, and then
In order to register the interrupt prohibition qualification, a predetermined operation is performed, in this case, a specific number 111 is dialed. The central processing system CP detects the specific number 111 dialing of extension A via the register trunk ORT and activates the interrupt registration section 01. The interrupt registration unit 01 sets 1 in the interrupt qualification field OF corresponding to the extension A in the storage device M, and registers the interrupt prohibition qualification of the extension A. Central processing system CP Hashidisutorunk ORT
A special tone indicating completion of registration is sent back to the calling extension A. Next, extension A dials trunk T and the number for the subsequent route, causes central processing system CP to set route 2 of network NW, and starts desired communication. During this communication, an interruption is required from the office line relay stand ATT to the extension A.
The central processing system CP receives an interrupt request from the central office relay board ATT and learns that the interrupt qualification field OF of extension A in the storage device M is 1, and that extension A has registered the interrupt prohibition qualification. is recognized, the interrupt connection is not executed, and the central office line relay stand ATT displays an interrupt disabled display. When extension A finishes communication requiring interruption prohibition and is restored, the central processing system CP detects the restoration of extension A and activates the interrupt registration unit 01. The interrupt registration section 01 stores the interrupt qualification section OF'of extension A in the storage device M.
and cancel extension A's interrupt prohibition status. Next, extension B makes a call to perform communication via trunk L that does not require interrupt prohibition. After extension B is connected to the register trunk ORT via route 3 of network NW in a well-known manner, it dials the number for trunk L route connection and causes central processing system CP to set route 4 of network NW. , initiate the desired communication. Meanwhile, interrupt registration section 0
1 for registering extension B's interruption prohibition qualification, the specific number 1
11 is not dialed, it is not executed, and the interrupt qualification section OF of extension B in the storage device M remains set to 0. During this communication, an interrupt is required from the office line relay stand ATT to the extension B. The central processing system CP receives an interrupt request from the central office relay board ATT, learns that the interrupt qualification section OF of extension B in the storage device M is 0, and
recognizes that the interrupt prohibition qualification has been canceled, causes the network NW to set route 5, and executes an interrupt connection from the office line relay stand ATT to the extension B that is currently communicating. As is clear from the above explanation, according to this embodiment, the registration of an extension's interruption prohibition qualification is performed by specifying the registration of an extension's interruption prohibition qualification before dialing the called party number when each extension makes a call that requires interruption prohibition. number 11
The call is terminated by dialing 1, and when the call is terminated, the barge entitlement is removed.

Therefore, any extension is eligible to disable interrupts only for calls that require disable interrupts. It should be noted that FIG. 2 is merely one embodiment of the present invention. For example, the operation performed when registering an extension prohibition qualification may be modified in various ways as described below, but the effects of the present invention will not change in any case. do not have.

If extension A is to repeatedly carry out communications that require interrupt prohibition during a certain period, it will make a call before starting the communication, connect to the register trunk ORT, and then continue its interrupt prohibition status. For registration, a predetermined operation is performed, for example, dialing another specific number 112.

The central processing system CP detects the specific number 112 dial of extension A via the register trunk ORT and calls the interrupt registration section 0.
Start 1. The interrupt registration section 01 sets 1 in the interrupt qualification section OF of extension A in the storage device M, but the specific number 111
Unlike when extension A is dialed, even if extension A is restored, the interrupt registration section 01 remains in the interrupt qualification section OF of extension A in storage device M.
is not reset to 0.

Therefore, extension A continues to have the interrupt prohibition qualification. If extension A is restored after hearing a special sound returned from the register trunk ORT indicating the completion of registration, the registration of the interrupt prohibition qualification is completed. Thereafter, every time Extension A makes a call, even if he does not have to perform an operation to register the interruption prohibition qualification, all interruptions to communication are prevented. When extension A no longer requires interrupt protection, it calls and registers trunk ORT.
After connecting to , a predetermined operation is performed, for example, by dialing a specific number 113, in order to cancel the interrupt prohibition qualification. The central processing system CP detects the specific number 113 dialing of extension A via the register trunk ORT and activates the interrupt registration section 01. The interrupt registration unit 01 sets 0 in the interrupt qualification section OF of the extension A in the storage device M, and cancels the interrupt prohibition qualification of the extension A. The central processing system CP causes the register trunk ORT to return a special tone indicating completion of release to the calling extension A.
Thereafter, any communication that does not involve registering the interrupt prohibition qualification of extension A will not prevent the interrupt connection.

Furthermore, in FIG. 2, interrupt registration section 0 in the central processing system CP
1 and the functions of the interrupt qualification section OF in the storage device M may be modified in various ways, but the effects of the present invention will not change in any case.

As described above, according to the present invention, in an automatic private branch exchange having an interrupt function, any extension can register and cancel the interrupt prohibition qualification by performing a simple operation on its own only when necessary. A flexible interrupt prohibition registration canceling method that can fully cope with increasingly complex communication formats is realized.
