Description

Automatic Broadcasting Method for Absence of Exchange System

The present invention relates to a simple switching system, and in particular, the automatic switching method of the switching system that automatically broadcasts to the inside of the building or the office when the extension subscriber does not have a seat and does not answer even when the subscriber telephone is sent a predetermined number of rings. It is about.

In general, when an extension subscriber of a simple exchange system picks up a handset to talk to a desired party, the simple exchange system connects the corresponding subscriber to the trunk line and outputs a dial tone from the local exchange to the subscriber. It is possible to make a dialing state so that a call can be made, and when a call is made between extension subscribers, the extension subscriber presses an extension number to be called to make a call by sending a ring tone to the corresponding extension subscriber.

A conventional simple exchange system that provides the functions described above, when a call is made to any extension subscriber from a trunk line or extension, can notify the extension subscriber that the call has been made when the extension subscriber is not present. Due to the absence, the operator or a co-worker must directly notify the extension subscriber that the call has occurred, so there was a problem in that a time loss occurs.

The present invention has been made to solve the above-described problems, and even if the extension subscriber does not have a seat because the extension subscriber does not have a seat, even if the ring tone is transmitted to the extension subscriber a certain number of times, the building is automatically received. It is an object of the present invention to provide an exchange system that can reduce the time loss of human resources by allowing the user to promptly respond to an extension subscriber call by performing an announcement broadcast inside or in an office.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the simplified exchange system having the automatic broadcasting function according to the present invention includes the trunk line interface 120, the switching unit 122, the extension interface 124, and the first and second tone detection units 126 and 130. ), A control unit 128, a memory unit 132, and a digital audio unit 134.

In the simple switch 12, the trunk line interface 120 matches signals input and output through trunk lines connected to the local exchange 10, and the station interface 124 is a signal input and output to the extension telephones 14 and 16. In accordance with the present invention, the switching unit 122 forms a communication path for the extension subscriber by switching the communication path between the trunk line interface 120 and the extension interface 124. In addition, the first tone detection unit 126 detects the tone signal from the local exchange 10 and applies it to the control unit 128, and the second tone detection unit 130 from the extension telephones 14 and 16. The tone signal is detected and applied to the control unit 128, the memory unit 132 stores an operation program and data, and the control unit 128 is operated according to the operation program stored in the memory unit 132 to perform the operation of each circuit unit. The digital voice unit 134 transmits the recorded voice data to the external speaker 18 according to the control command of the controller 128.

The operation of the simple switch 12 according to the present invention configured as described above will be described in detail with reference to FIG. 2.

When an outsider connected to the local exchange 10 dials to call an extension telephone housed in the simple exchange 12, the trunk line ring applied through the local exchange 10 is received by the simple exchange 12, and the controller 128 When a call is set up with an outsider (step S1) and the outsider dials the extension number of the extension telephone 14 to be called (step S2), the control unit 128 transmits the dial tone to the first tone detection unit 126. Through the extension interface 124 to detect the call to the extension telephone 14 to send a ring tone, and the call ring is ringing in the extension telephone 14 as the call tone is sent (step S3).

Subsequently, the control unit 128 of the simple switch 12 confirms whether the user of the extension telephone 14 has picked up the handset, that is, if the user of the extension telephone 14 responds (step S4).

Here, when the user of the extension telephone 14 responds, the controller 128 controls the switching unit 122 to form a communication path between the outsider and the extension telephone 14 to make a call with the outsider (step S5), Otherwise, when the user of the extension telephone 14 does not answer, the control unit 128 determines whether the number of times of the ringing tone of the extension telephone 14 exceeds the predetermined number (step S6).

At this time, the control unit 128 of the simple switch 12 returns to the step S3 if the number of times of the ring tone has not exceeded the predetermined number of times and resends the ring tone, and if the number of times of the ring tone has been exceeded the predetermined number of times, the automatic broadcasting function. Whether or not this is set is checked (step S6).

When the extension subscriber sets up the automatic broadcasting function, the toggle switch installed in the extension telephone 14 is set manually, or the combination of the number buttons and the '#' and '*' buttons installed in the extension telephone 14 is input. The controller 128 checks whether the automatic broadcasting function is set based on the corresponding setting information.

If the automatic broadcasting function is not set in step S7, the process returns to step S3 to resend the ring tone, and if the automatic broadcasting function is set, the control unit 128 of the simple switch 12 sends a control command to the digital voice unit 134. And outputs the voice data recorded in the digital voice unit 134 to the external speaker 18 to broadcast the call to the extension telephone 14 to the user (step S8).

At this time, the external speaker 18 has an audible range for the office or building, and the voice data stored in the digital voice unit 134 has a plurality of fields, and consists of subscriber identification data and a plurality of message data.

In more detail, the digital voice unit 134 stores subscriber identification data including extension number data, name data, and calling data, and message data in order, and is authorized by the sender in step S2. Based on the extension number, subscriber identification data (name data, calling data, extension number data) and message data are broadcasted in combination with each other.

For example, the extension number of the extension telephone 14 is 10, the user's name is Hong Gil-dong, the title is exaggerated, and the message data comes from the name data + nominal data and the extension data. If you want to answer the phone, the digital voice unit 134 is the manager, Gil-dong Hong, the call came to 10, so as soon as possible, please answer the call at the spot and outputs a broadcast message.

At the same time, it may be desirable to inform the external sender of the guidance voice, 'Please wait for a while because the extension user is looking for your location.'

In addition, if you are going to go out for a certain period of time and cannot hear the above automatic broadcasting, the user of the extension telephones 14 and 16 may turn off the automatic broadcasting function.

On the other hand, since the extension user who has listened to the automatic broadcast needs a certain time to reach the place where the extension telephone 14, which is his working seat, is located, the controller 128 of the simple switch 12 performs the operation of step S8. After that, the timer for setting a delay time for a predetermined time is operated (step S9).

Then, the control unit 128 performs a time delay loop on the operation program and continuously checks whether the extension telephone 14 responds, and if a response is detected, immediately exits the delay loop and calls the extension telephone 14 and the external caller. If the call is connected, and if a response is not detected, an announcement voice for guiding that the called extension subscriber is in a state that cannot receive a call is sent to an external sender (step S11), and the operation is terminated.

In the above operation description, a case where a call is received from a trunk line has been described as an example, but the present invention is not limited thereto, and an automatic broadcast function is performed in the same manner as described above for calls generated between extension telephones.

According to the present invention as described above, it is possible to reduce the work of the operator, as well as to reduce the operator's work because it automatically broadcasts to the extension subscriber that is not in the outside or inside the phone to notify the work There is an advantage to improve the efficiency.
