    The present invention relates to a call waiting method of a tele-electronic switch which properly waits for a call of a subscriber requesting a call to a CENTREX subscriber in a tele-electronic switch. In the case of a busy subscriber, when a particular subscriber calls the Centrix subscriber who is busy, a busy tone is connected to the caller who made the call, and the caller has no shortcoming. In an electronic exchange, a call from a Centrix subscriber is held by a call from a registered Centrix subscriber with a call waiting function, waiting for the call of the subscriber requesting a call, and the call being controlled by the call center subscriber with a call waiting function. Since the use is various and convenient, the above-described drawbacks can be improved.

    Call waiting method of electronic exchange
    The present invention relates to a call waiting method of an electronic switchgear, and more particularly, to a call waiting method of an electronic switchgear that properly waits for a call of a subscriber requesting a call to a CENTREX subscriber in a telephone switcher. It is about.
    In this regard, in the related art, when a call request is received from an external CENTRIC subscriber, the CENTRIC subscriber and the external subscriber can make a phone call by receiving the call.
    However, in this conventional technique, when a Centrix subscriber is busy, when a particular subscriber calls the busy Centrix subscriber, a busy tone is connected to the caller making the call. There was a flaw inevitably to try the call.
    The present invention has been made to solve the above-mentioned shortcomings, and the call waiting function is queued by waiting for a call of a subscriber requesting a call to a CENTRYS subscriber in a call waiting function registered in a telephone exchange. The object of the present invention is to provide a method of waiting for a call of an electronic switching system to be controlled by a registered Centrix subscriber.

    The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.
    Hereinafter, an embodiment of the present invention for achieving the above object in detail.
    1 is a block diagram showing an embodiment of an electronic switchboard for applying the call waiting method of the electronic switchboard according to the present invention. The line control subsystem 10 includes an extension subscriber, a general subscriber, and a subscriber. It connects incoming subscriber's call into trunk inside the exchange system.
    Next, the CENTREX line subsystem 12 performs an exchange service for the Centrix subscribers among the incoming calls from the line control subsystem 10, and the subscriber line subsystem 14 ) Performs a switching service for the general subscriber among the incoming calls from the line control subsystem 10, and the trunk line subsystem 16 relays the trunk line among the incoming calls from the line control subsystem 10. Perform exchange service for incoming subscribers.
    In addition, the number translation unit 18 receives the above-mentioned incoming call through the corresponding subsystem, performs the translation of the caller's number, and informs the corresponding subsystem so that the exchange service is properly performed. 20 is sequentially connected via the input / output unit 22 and the personal computer 24, and receives the data related to the Centrix function by the operation of the operator's personal computer 24, and performs appropriate processing to be applied to the exchange system.
    FIG. 2 is a flowchart illustrating a step-by-step embodiment of the call waiting method of the electronic switchboard according to FIG. 1. When an incoming call is requested from a subscriber to a busy CENTRIC station, the subscriber is waiting for a call. If the subscriber is registered to the function and the call waiting function is activated, ring back tone is connected to the caller who requested the call (302,303,304,305).
    Next, in step 302, 303, 304, and 305, if the extension subscriber is a subscriber who is not registered in the call waiting function or the call waiting function is not activated, the busy tone is connected to the caller (306).
    Subsequently, after performing the above-described steps 302, 303, 304, and 305, a camp on tone is connected to the calling extension subscriber, and when the calling extension subscriber hooks, the device is held by the extension subscriber and the other party in the call. The tone is connected, and the extension subscriber notifies the release of the hold tone subscriber when the aforementioned hold tone is timed out without hook flashing (307, 308, 309, 310, 311).
    Therefore, in step 307,308,309,310,311 described above, after the holdtone is connected to the other subscriber who is in the call with the extension subscriber, the extension subscriber and the outgoing subscriber are in a busy state, and the extension subscriber is held out without a hook flash. The holdtone subscriber is notified of the release, and when the extension subscriber hooks the flash, he connects the caller to the holdtone and returns the two subscribers who were originally on the call back to the call (312,313,314,315,316,317).
    If the extension subscriber is not hooked on, the process returns to the beginning of the above-described steps (307, 308, 309, 310, 311). If the extension subscriber is hooked on, the extension is connected to the subscriber again. The user is placed in a call state (318, 319, 320, 321, 322).
    At this time, in the registration procedure of the call waiting function described above, the operator enters the call waiting function registration code using MMC (Man Machine Communication), and uses the MMC to call the call waiting function to the extension subscriber. By registering, if the extension has sent a hook tone to that extension, the subscriber will dial a dial tone to the extension that has sent the call. All you have to do is attach a confirmation tone to the Rix subscriber, and finally the extension's Centrix subscriber hooks on.
    In addition, when the call waiting function is canceled, the operator enters the call waiting function cancel code through the MMC, and if the extension subscribers registered to the call waiting function hook off, When the dialtone is connected, and the Centrix subscriber dials the call waiting function cancellation code, the Centrix subscriber hooks on after confirming a connection to the Centrix subscriber.
    As described above, the present invention waits for a call of a subscriber requesting a call to a call center Centrix subscriber whose call waiting function is registered in an electronic exchange, and the call is sent to the call center. By using the control, the phone usage of the Centrix subscribers is effective and diverse.

    Claims (1)
    [1" claim-type="Currently amended] When an incoming call is requested from any subscriber to a busy Centrix extension subscriber, if that extension is a subscriber registered to the call waiting function and the call waiting function is activated, the caller who requested the call is ringed back. first steps (302,303,304,305) of concatenating a tone;
    A second step (306) of connecting a busy tone to the caller if the extension subscriber is a subscriber who is not registered in the call waiting function or the call waiting function is not activated in the first step (302, 303, 304, 305);
