The present invention relates to a cable broadcasting and response method and apparatus for a switchboard in a private exchange.

In general, when a predetermined subscriber wants to broadcast announcements in a private exchange and a key phone system, when a specific key is sequentially pressed by an appointment, it is checked and processed in the system. But announcements were not allowed on the switchboards of private exchanges.

Therefore, an object of the present invention is to provide a method for informing the announcement by the operator's announcement or connecting the subscriber (outside the trunk line, leased line) when the subscriber finds the person inside the private exchange.

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

A memory unit 20, an interface 30 for buffering and interfacing the input / output data of the CPU 10, and a subscriber circuit 40 for interfacing between systems while supplying a voice current of a voice band to a telephone of an extension subscriber. And a switching circuit 50 for multiplexing digital tones and speech data under the control of the CPU 10 to send data corresponding to a voice band to a corresponding time slot, and the CPU Tone supply (60) for generating various tone signals under the control of (10) and outputting them to the switching circuit 50, and the internal subscriber (STN) of the subscriber circuit 40 Dual Tone Multi a tone receiver (DTMF Receiver) 70 for analyzing the trequency and inputting corresponding digit data to the CPU 10, and a tone sender for generating a double tone and coding and outputting the double tone by the control data of the CPU 10. A DTMF sender 80 and a CO line circuit 90 for interfacing a signal coming in from a CO line by forming a trunk line loop by scissing a CO line which is idle under control of the CPU 10. And a scissor response signal (Seizure) by an incoming signal signal by sending a predetermined input signal by scissoring a dedicated line under control of the CPU 10, and transmitting a scissor response signal (Seizure) between the station and the station. A dedicated line circuit 100 for interfacing a dedicated line, a ring generotor 10 for generating a ring signal under the control of the CPU 10, and in case of wired broadcasting in the premises, Caesar the broadcasting circuit 120 by the control and the CPU through the speaker 130 By controlling the control circuit 10, the broadcasting circuit 120 that broadcasts through the switching circuit 50, and the various keys (Access) accessed by the CPU (10) by analyzing the control diagram is exchange circuit (hereinafter referred to as And "switchboard" (140).

When the purpose of the switching circuit 140 is added, the incoming signal for distributing the incoming call from the trunk line circuit 90 or the dedicated line circuit 100 from the STN of the subscriber circuit 40 and accordingly the extension of 40, 90, 100, It is a switchboard interface circuit that acts as a relay for generating and connecting new calls to trunk lines and leased lines.

FIG. 2 is a flow chart illustrating a guide flow according to the present invention, a first step of checking a broadcast key input of a switchboard, a second step of checking whether a total zone number is pressed when the broadcast key is used in the first step, and the second step. When the whole zone number is pressed in the process, a confirmation sound is exchanged as a switch and a speaker is heard in the entire zone, and then a call is performed between the speakers of the switchboard. In the second process, the whole zone is not pressed. If not, it checks whether a specific zone number is pressed and gives a confirmation tone to the switchboard, opens the speaker of the zone, plays the confirmation tone, and makes a call between the switchboard and the speaker.

3 is a response flow chart according to the present invention, a first step of checking whether an extension subscriber has responded, and a second step of checking whether it is time for the extension subscriber to respond when there is a subscriber response in the first step; In the second step, when the time to respond in the second step has passed, the third party interrupts the pending sound and generates a call as an exchange to be originally broadcasted, and when the extension subscriber responds in the first step, the reserved sound is held by the subscriber. Hang up and the extension consists of a fourth process of connecting the call.

Therefore, when a specific embodiment of the present invention will be described in detail with reference to Figs. 1-3, the present invention generally refers to a case in which an operator makes an internal broadcast and a call and a call that is incoming from the trunk line 90 or the leased line 100. If you are in the middle of the announcement and the process of automatic response. Normally, the speaker 130 of FIG. 1 may be connected to eight, and the speakers 130 may be installed at a predetermined place in the premises so that broadcasting may be performed by zones in which each speaker 130 is located or simultaneously in the entire zone. It may be.

If only the broadcast is performed in the exchange, the CPU 10 checks the input of the broadcast key on the switchboard 150 in step (2-1) and checks whether the entire zone number is pressed in step (2-2) when the broadcast key is the broadcast key. (10) checks. At this time, under the control of the CPU 10 in the zone number date and time (2-5), the confirmation sound is heard through the tone supply circuit 60 through the switching circuit 50, and the switching circuit 140 and the broadcasting circuit 120 are switched. After the control by listening to the confirmation through the switching circuit 50 to make a call between the switchboard 150 and the speaker 130.

However, when the whole zone number is not pressed in step (2-2), the CPU 10 checks whether a specific zone number is pressed and checks with the switchboard 150 in step (2-4). Hear the sound and open the speaker 130 of the corresponding zone to hear the confirmation sound and open the communication path between the switchboard 150 and the speaker 130.

On the other hand, if the switchboard 150 has previously talked to an external subscriber through the trunk line circuit 90 or the dedicated line circuit 100 of FIG. 1 in the process (2-1) of FIG. 2-3) (2-4) (2-5) through the same process, and after pressing (2-4) (2-5) switchboard (150) answer key (specific key) to talk to the CO line The call hears the hold tone of the tone supply circuit 60 from the tone supply circuit 60 to the subscriber of the trunk line circuit 90 through the interface unit 30 under the control of the CPU 10. Reserved on switchboard 150.

In this case, when the subscriber who listened to the announcement broadcasts the telephone and calls the switchboard 150, the subscriber station responds by interconnecting the reserved local call with the incoming internal call on the switchboard 150 (at this time). The way of calling the switchboard is the announcement broadcast response number + the corresponding trunk line number) and the switchboard 150 presses the auto answer key in the process after (2-4) (2-5). Pick up the station subscriber (STN) picked up to listen to the announcement now waiting for the switchboard 150 is completely exited.

And the response process is when the subscriber receives the announcement and listens to the telephone at the nearest extension telephone and presses the announcement announcement response number + the corresponding call number while checking the subscriber's response in the process (3-1) (3 In the process of -2), the call subscriber hears a pending sound and connects a call with the extension subscriber, so that the call can be mutually communicated with the subscriber who is found by the corresponding station by the control of the CPU 10 of FIG.

If the station subscriber does not respond in the process (3-1), after a certain time has elapsed (3-1) → (3-3) → (3-4) by monitoring (monitoring) the CPU 10 of FIG. Through the process of receiving a guide broadcast on the switchboard 150 may be re-information broadcast again. As described above, the case in which the switchboard 150 relays the response or the automatic response or the extension method of the extension subscriber who listens to the announcement is the same.

As described above, the switchboard relaying various calls of the private exchange has the advantage of delivering announcements by independently guiding announcements. If you are in the receiving premises has the advantage of automatic connection.
