Abstract

PURPOSE:To release a set CAMP-ON by designating the time of CAMP-ON release after the setting of CAMP-ON and releasing the CAMP-ON automatically when the operation of talking end is not applied till the designated time. CONSTITUTION:A main switch 1 accommodates subscriber circuits 3, 5 connecting to extension telephone sets 2, 4. For example, when the subscriber of the extension telephone set 2 calls the subscriber of the extension telephone set 4 and the extension telephone set 4 is busy, a caller subscriber dials a specific number of CAMP-ON relating to the setting of CAMP-ON. Moreover, the caller subscriber designates the time when the CAMP-ON is automatically released and hooks off. A CPU 6 starts a clock circuit 7. The clock circuit 7 counts the elapsed time and the CAMP-ON is automatically released when the operation of the talking end is not applied till the designated time.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a camp-on system for private branch exchange equipment.

[Conventional technology]

Camp On is a function that notifies the end of a call when the other party's extension subscriber is in the middle of a call. Some private branch exchanges are equipped with this camp-on function.

For such exchanges, the camp-on method sets and cancels camp-on. When canceling camp-on, some operation by the person who set camp-on is required.

As this operation, for example, the setter makes some kind of response to the ringing indicating the end of the call. Also, dial the camp-on cancellation special number. Camp-on is canceled by such an operation.

[Problem to be solved by the invention]

The conventional camp-on method requires an operation by the setter to cancel camp-on. For this reason, the conventional camp-on method has the following drawbacks.

For example, if the call on the other party's extension goes on for a long time, the person who made the call may forget that they have set up camp-on and leave their desk. In such cases, other people may respond to the ringing.

An object of the present invention is to provide a camp-on method that eliminates such drawbacks and can automatically cancel camp-on.

[Means to solve the problem]

The present invention provides a camp-on method for canceling camp-on set on a private branch exchange device that accommodates an extension.When the called extension is busy, a special number for camp-on setting is dialed, and after setting camp-on, the time for canceling camp-on is determined. It is characterized by automatically canceling camp-on if there is no operation to end the call by the specified time.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an example of a private branch exchange device for implementing the present invention. FIG. 2 is a flowchart showing the operation of the private branch exchange device of FIG. 1.

The private branch exchange system of FIG.
and a clock circuit 7 connected to the CPU 6. Note that the number of extension telephones accommodated in the main switch 1 is not limited to two.

The main switch 1 of such a private branch exchange device connects the telephone extension telephones accommodated therein.

The clock circuit 7 counts the time specified by the subscriber of the extension telephone.

The CPU 6 controls the main switch 1 and the clock circuit 7.

In such a private branch exchange, the camp-on method operates according to the flowchart shown in FIG.

For example, a subscriber on extension telephone 2 calls a subscriber on extension telephone 4. That is, the subscriber of extension telephone 2 goes off-hook and dials the extension number of extension telephone 4 (
Step SL).

When the extension telephone 4 answers here, the extension telephone 2 is connected to the subscriber circuit 3. It is connected to an extension telephone 4 via a main switch 1 and a subscriber circuit 5. The CPU 4 controls such connections.

However, if the extension telephone 4 is busy (step S2
), the calling subscriber may set up camp-on. In such a case, the subscriber on the calling side dials the camp-on special number related to the camp-on setting (step S3). Further, in step S4, the subscriber on the calling side may specify a time period until the camp-on is automatically canceled.
), goes on-hook (step S5). Here, the clock circuit 7 is activated.

In such a state, there may be a ringing of the extension telephone 4 indicating the end of the call. Since this is a cancellation of camp-on (step S6), camp-on is canceled.

By the way, there are cases where the extension telephone 4 does not ring to indicate the end of the call, and the subscriber of the extension telephone 2 who has set camp-on does not cancel camp-on.

On the other hand, the clock circuit 7 is counting the elapsed time.

Then, when the time set by the subscriber of the extension telephone 2 has elapsed (step S7), camp-on is automatically canceled.

〔Effect of the invention〕

As described above, according to the present invention, there is an advantage that camp-on can be automatically canceled when there is no longer a need for a call after a specified time has elapsed after setting camp-on.

Claims (1)

[Claims] (1) A camp-on method that cancels the camp-on setting set on the private branch exchange device that accommodates the extension, in which the special number for the camp-on setting is dialed while the called extension is busy, and the camp-on is activated after setting the camp-on. The camp-on method is characterized by specifying a cancellation time and automatically canceling camp-on if there is no operation to end the call by the specified time.
