[0001] METHOD FOR CONFIRMING BROAD CASTING AUDITION STATE OF PRIVATE BRANCH EXCHANGE SYSTEM [0002]

The present invention relates to a broadcast response confirmation method in a simple exchange system, and more particularly, to a broadcast response confirmation method for confirming whether a partner has listened to a broadcast when performing a broadcast function in a plurality of exchange systems connected by a dedicated line.

In general, when a broadcasting function is performed in an exchange system such as a key telephone or a simple exchange, a system calls a plurality of systems at the same time, and a desired voice message is transmitted and heard. Therefore, it was impossible to know whether broadcast contents were correctly transmitted by listening to broadcast contents in the partner system.

Accordingly, it is an object of the present invention to provide a broadcast response confirmation method for confirming whether a partner system correctly listened to a broadcast when a broadcast function is performed in an exchange system.

It is another object of the present invention to provide a broadcast response confirmation method for receiving a broadcast acknowledgment signal from a partner system and recognizing the presence or absence of broadcast contents when a broadcast function is performed in an exchange system.

According to an aspect of the present invention, there is provided a system for transmitting broadcasts in a plurality of switching systems that listened to broadcast contents when a broadcasting function is performed, and a broadcasting listening confirmation signal indicating that the broadcasting is listened to is transmitted by a polling method, The presence or absence of the broadcast reception in the exchange system is recognized.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram illustrating a connection structure between a simple switching system for performing a broadcasting function according to an embodiment of the present invention, and a connection state of two simple switching systems is shown for convenience of explanation, although the two or more key telephone systems can be connected. The first key phone system 100 and the second key phone system 200 are connected to each other by an exclusive line (EM) line. A plurality of telephones are connected to the first keyphone system 100 and the second keyphone system 200, respectively.

FIG. 2 is a control flowchart of a first key phone system 100 for confirming a broadcast content listening response when a broadcasting function is performed according to an embodiment of the present invention.

3 is a control flowchart of a second key phone system 200 for confirming a broadcast content listening response when a broadcasting function is performed according to an embodiment of the present invention.

The operation of the preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3. FIG.

In the embodiment of the present invention, a case where the first keyphone system 100 broadcasts to the second key phone system 200 will be described. The first key phone system 100 and the second key phone system 200 typically incorporate a DTMF receiver.

First, the user of the first keyphone system 100 presses the broadcast button of the key input unit of the extension telephone 101 to broadcast. At this time, the first keyphone system 100 checks whether a broadcast key signal is inputted from the extension telephone 101, If the key signal is input, the process proceeds to step 102. In step 102, the first keyphone system 100 receives a channel of a leased line and dials the telephone number for broadcasting, connects the second keyphone system 200 to the call channel, and transmits a broadcast request signal. Then, in step 103, the first keyphone system 100 controls the extension telephone 101 to blink the LED, which is a display device. At this time, the second keyphone system 200 checks if a broadcast request signal is received from the first keyphone system in step 201, and proceeds to step 202 when a broadcast request signal is received. In step 202, the second key phone system 200 detects whether or not the broadcast is possible. That is, it searches whether other extensions are broadcasting or restricted broadcasting by rating. At this time, if it is not possible to broadcast, the process proceeds to step 203, where the second key phone system 200 transmits a NAK signal, for example, a DTMF * signal indicating that broadcast can not be used, to the first keyphone system 100. In step 104, the first keyphone system 100 searches the DTMF receiver to see if a signal indicating that broadcasting is disabled is received. If the signal indicating that the broadcast is unavailable is received, the process proceeds to step 105, where the first keyphone system 100 generates an error tone to the extension phone 101 to indicate that the broadcast is impossible. In step 202, the second keyphone system 200 transmits a DTMF 101 signal to the first key phone system 100, for example, a system number indicating that the second key phone system 200 is in a broadcastable state. At this time, the first keyphone system 100 checks whether the DTMF signal 101 indicating the broadcasting usable state is received in step 106, and proceeds to step 107 when the DTMF signal 101 indicating the broadcasting usable state is received. In step 107, the first keyphone system 100 turns on the broadcasting LED of the extension telephone 101 to indicate that it is in a broadcasting state. In step 108, the first keyphone system 100 receives the broadcast contents input by the user from the extension phone 101 and transmits the broadcast contents to the second key phone system. Then, the second key phone system 200 causes the extension phone 201 to listen to the broadcast contents in step 205. When the user of the extension telephone 201 of the second key phone system 200 finishes listening to the broadcast contents, the user presses the CON button provided in the extension telephone key input unit. At this time, in step 206, the second keyphone system 200 checks whether the CON key signal indicating the end of listening to broadcast contents is inputted from the extension telephone 201. [ When the CON key signal is input, the second key phone system 200 transmits a broadcast listening confirmation signal to the first key phone system 100 in step 207, and cancels the call loop in step 208 in step 208. In step 109, the first keyphone system 100 checks whether a broadcast listening confirmation signal indicating reception of a broadcast has been received. If the broadcast listening signal is not received, the first key phone system 100 proceeds to step 111. If a broadcast listening confirmation signal is received, In step 110, the first keyphone system 100 controls the extension phone 101 to turn off the broadcast LED. Then, it is checked whether the communication loop of the broadcasting station is interrupted. If the communication loop is blocked, the broadcasting is canceled by proceeding to step 112.

On the other hand, when broadcasting is performed simultaneously to a plurality of key telephone systems at one time, if the broadcasting is possible for each system, the system number of the broadcasting system is polled to broadcast the broadcasting system. Then, the broadcasting LED corresponding to the number received from the calling system can be turned on so that the system can listen to the broadcasting and recognize which system has not listened to the broadcasting.

As described above, according to the present invention, when a broadcasting function is performed in a plurality of switching systems connected to each other through a leased line, a broadcast listening acknowledgment signal indicating that the broadcasting has been listened to is transmitted to a system that listens for broadcasting contents, There is an advantage that the broadcast system can recognize the presence or absence of the broadcast.
