The present invention relates to a simultaneous command method that can be serviced in an exchange or a key phone system, and in particular, after dividing the extension subscribers into a specific group, all the speakerphone extension subscribers in a predetermined group can be commanded through the speakers in the same group. The present invention relates to a subscriber one-way forced configuration method.

Conventional Japanese command methods include a method of installing and commanding an external speaker arbitrarily in an exchange system, and a method of forcibly opening the speaker to only one of the extension subscribers of a specific speaker phone and commanding the speaker. The conventional Japanese command method will be described in detail with reference to FIGS. 1 and 2, and FIG. 1 is a ring driving block diagram of a known time switch 20 and an analog telephone card, which is controlled by the central controller 50. By addressing the transmitter 1 time switch 20 and simultaneously connecting to the time switches 20 of the multiple receivers 2, the sender may be one person, but the receiver may be multiple people. That is, the command can be made by controlling the time switch 20 so as to spray one transmitting end 1 address simultaneously with the addresses of several receiving end 2 due to the characteristics of the time switch 20. If one subscriber at the receiving end 2 responds with the receiver while checking the address, the responder's pod is checked and addressed, and then all the time switches 20 except for the address are disconnected and the receiving end of the original sender 2 is received. Both calls are made by connecting the time switch 20 of the transmitting end 1 of the responder to the time switch 20 of the responder. Of course, at this time it is configured to reset the codec (10,30) of the remaining recipients and release the opponent.

FIG. 2 is a ring driving block diagram of an analog telephone card. The ring relay 42 is simultaneously driven after the mode search and addressing of a port of the telephone ST1 not in use in the same group. When the first answer is picked up by the receiver, all ring relays 42 in the group are disconnected, the responder's port is checked, the codec 44 is addressed, and the call is established by connecting the sender and the responder's time switch 20 to both parties. . At this time, of course, it is configured to release the status of the remaining subscribers.

1 and 2 are known configurations, and FIG. 3 is a conventional flow chart. The conventional method of FIG. 3 checks in step (2a) whether the dialed telephone number is busy and gives a ringing tone to the calling party in step (2b) when the call is busy. However, when the call is not busy in step (2b), it is checked whether the subscriber is a speakerphone subscriber in step (2c).

When the speakerphone subscriber is not the speakerphone subscriber in step (2c), the ringer 42 is driven in step (2e) to raise the ring to the corresponding phone. Run it, put the ring on the speakerphone for a while and hang up. Subsequently, in step 2f, the condeck 30 is driven and the time switch 20 of the calling party is connected to the receiver timing switch of the speakerphone subscriber to make a one-way call.

After the one-way communication path is formed in step (2f), it is checked whether the receiver has heard the receiver in step (2g). In step (2h), the calling party of the speakerphone is connected to the receiving end time switch 20 of the calling party in step (2h). Connect the time switch to make a two-way call. When the handset is not picked up in step (2g), it is checked whether the handset is lowered in step (2i).

When the receiver is put down in the process (2i), the connection with the codecs 10 and 30 on both sides is disconnected from the time switch (2o) in the process (2j) and made free (one direction for one subscriber speakerphone). In the case of a forced call, as described above, when a conventional external speaker is to be known, the serial number of the speaker must be known, and then the time switch 20 of the corresponding receiver 2 of the speaker is known after knowing whether the speaker is in use. ) Is made by connecting the time switch 20 of the transmitting end 1 of the caller side. When any extension subscriber forcibly opens the speaker through the speakerphone and checks whether the extension subscriber is busy or not, after driving the speaker of the speakerphone, the time switch of the receiving end 2 is operated. (20) was connected to the time switch 20 of the transmitting end 1 on the calling side so as to talk in one direction.

For this reason, although the conventional exchange system has speakerphones, there is no way to make Japanese order through these speakerphones, and in order to make Japanese order, external speakers must be separately installed in the system, and these speakers may be installed outdoors. There was no way to inform everyone in a given department at the same time.

Accordingly, an object of the present invention is to use a speakerphone in accordance with the digitization of the sub-cell in the exchange system is a common method that can be commanded through the speakerphone of all extension subscribers in a specific group or without any external speakers in the system In providing.

In order to accomplish the above object, the present invention dials an arbitrary extension telephone number within a group after dialing an access card and searches all the speakerphone subscribers in the group to which the extension belongs, thereby forcing speakerphones not in use. The database is configured to be commanded in one direction by connecting the calling party time switch of the calling party to the receiving party time switch of these speakerphone subscribers. Process to enable bi-directional connection, and in the process of dialing the subscriber number that does not belong to any group in the process to raise the ring according to the normal call processing flow, and the speakerphone in the owner specific group None If there are any speakerphone subscribers in the group, even if they are in use, all the unused extension subscribers in the group are put in a ring, and the two subscribers make a two-way call with the first responder. When the ring is ringing after disconnecting, it is characterized in that the process is made to give the calling party a ring tone.

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

FIG. 4 is a flowchart according to the present invention, in order to implement according to the flowchart of FIG. 4, first, extension subscribers of an exchange or keyphone system should be divided into specific groups, and speakerphone subscribers should be present in those groups. .

In the first step of checking which group the dialed number is in, and the number dialed in the first step is not in a specific group. If the telephone does not have the speakerphone function while not in a call, the second process of driving the ringer to hand the ring to the telephone and the telephone number dialed in the second process belong to the specific group. A third step of checking whether all the phone numbers are used by the speakerphone function and checking whether their speakerphones are busy, and in the third step, all the subscribers (speakerphones) having no phone or speakerphone function in the group or And audible phone), the caller hears a ringing tone when the call is in progress, and has a speakerphone function in a specific group. The fourth step of driving a ringer of the speakerphone of the analog phone which is not in a busy state to raise a ring for calling the corresponding phone, and when there is a telephone having a speakerphone function that is not in the third process. When the phone has the speakerphone function in the second step, the ringer is driven to open the speakerphone, raise the ring for a while, hang up again, drive the codec of the speakerphones, and then call the calling party time switch to the calling party time switches. Answering when answering by checking whether the group has picked up the receiver by connecting the location at the same time and making a call in one direction and connecting and ringing in the one-way call in steps 4 and 5 Connect the calling party time switch of the telephone with the receiving party time switch of the calling party to make a two-way call, and The sixth process of disconnecting the receiver's time switch and codec and making it free state, and if the receiver does not answer the call when it is not answered in the sixth process, continues the process and continues the process. When put down, the seventh step is to turn off the time switch and codec / ringer and to free all phones.

Therefore, a specific embodiment of the present invention will be described in detail with reference to FIGS. 1 and 4.

From step (3b), the memory unit of the central controller 50 finds out whether there is a group to which the telephone number dialed in step (3a) belongs. In step (3b), if the group is not in the corresponding group in step (3c) and checks whether the corresponding number is in a call, in step (3e), a call tone is heard to the calling party, and in step (3c) Otherwise, check whether the number is speakerphone in step (3f). In step (3f), when the corresponding phone is the speaker phone, the step (3j) is executed and when the phone is not the speaker phone, the ring signal of the ring generator 41 periodically generated by addressing the corresponding analog phones by the ring relay 42 is performed. In order to be controlled, (3g), the ringer is driven to raise the ring on the telephone.

On the other hand, when it is not the corresponding group in step (3b), the phone searches for all the speakerphone functions belonging to the group in step (3b). From the search result of step (3b), it is checked whether there is a telephone with a speakerphone function in step (3h). Here, if there is a telephone with speakerphone function, check whether there is speakerphone that is not busy in the process (3i). However, if there is no telephone with a speakerphone function or no speakerphone function in the process (3h) (3i), and if there is no telephone in the speakerphone function, in step (3k) it is checked whether there is a telephone in the group.

If there is no telephone in the process (3k), the caller hears a ringing tone. If the telephone is not used, the ringer is driven to raise the call ring to the corresponding telephones.

In the process (3i), when the state of the speakerphone is not in use, as shown in FIG. 1, the central processing unit 50 gives a message to address the transceiver of these speakerphones to ring the ring for a while. At this time, the speaker unit receives this from the transmitting and receiving unit, the CPU 50, addressed through the codec (10, 30), the voice control time switch 20 is switched to the ring relay 42 for a short time (3j) Drive in the process to raise the ring and hang again. When the main processing unit 50 receives the address of the speakerphones from the main processing unit 50 to switch quickly the time switch 20 corresponding to each speakerphone, the central processing unit 50 analyzes the information. After addressing according to the analyzed information, the voice switch is switched through the codecs 10 and 30, and then a speaker is connected, thereby enabling one-way communication in the process (3t).

Of course, in the main system, the reception time switches 20 corresponding to these speakerphones were connected to the sender's transmission time switch 20. Therefore, in the process (3n), the ring is heard in the process (3t) or (3l). When a one-way path is formed, i.e., a one-way call or an analog phone rings, and when the ring is ringing, it is detected in step (3n) whether there is a subscriber to listen to the handset in the group. If the ringing subscriber listens to the handset, address it in the main system to cut off the ring relay 42, and instead, by connecting the highway transmitting and receiving end 45 to the subscriber via the codec 44 in both directions (3p). You can make a call. Of course, all analog phones raised by the ring in the group break the ring relay 42. On the other hand, if a speakerphone subscriber who is talking in one direction picks up the handset, the speakerphone set is searched for in the process (3n) to disconnect the speaker of the voice time switch unit 20, switch to the handset again, and then pick up the handset as the main system. Inform. The main system receives this message, analyzes whether it is also received from the speakerphone, and addresses it, and then makes a two-way call by connecting both time-switches of the corresponding highway. Of course, at this time, the rest of the speakerphones in the group are also sent to the message to turn off the speaker (3g, 3r) in the free state.

However, if the receiver hangs up at step (3o), it returns to step (3t) and repeats the above execution.

The above description is as follows.

Dial a command number, dial a random phone number in the group, get the group number to which the dialed phone number belongs, search all the phone numbers in the group for speakerphone, and check whether the speakerphones are busy. Drive a speaker such as a speakerphone that is not in a call, connect the time switch (MT8980D) in the switching system to the calling party time switches of the speakerphone subscriber in the group at the same time, and Able to make one-way call, and when all speakerphones in the group are busy or no speakerphone is in operation, ringer is ringed by subscribers who are not in the group. Two-way call by connecting time switch in both directions And it makes the rest of the subscribers to the free state. If the receiver first hangs up before responding in the group, all subscribers in the group are freed.

As mentioned above, if you want to order all the people in a certain department, you can make a command through the speaker of the speakerphone subscriber in the department without installing the external speaker in the exchange system. In this case, it is possible to communicate quickly by raising the ring at the same time and making a two-way call with the subscriber who answered first, and when the calling party announces the broadcast before answering at the receiving side, and then first drops the handset, all the subscriber phones in the group are free. The advantage of this feature is that the efficiency of the function can be improved.
