Description

Ring ringing method in key phone system

The present invention relates to a ring call method in a key phone system, and more particularly to a ring call method for ringing a ring to another extension group and a relay station at the same time when subscribers of a plurality of key phone phones belonging to a ring call group in a key phone system are absent. It is about.

In general, a key phone system uses one or more stations that can ring a ring for each CO line. However, when all users of the extension belonging to the called group are in a ringing state or there are a lot of subscribers who are away, the key phone system uses the MMC (Man Machine Code) to ring the ringing for a specified time and when there is no extension Switch ring to a station or trunk. At this time, the other party making the call waits for a long time until the call is connected, and it is considered that there is no other party and hangs up. However, the keyphone system may temporarily exclude users from ring extension groups, including their own extensions, from their extension groups, but it is difficult for keyphone users to know how many extension groups they belong to and their extensions belong to multiple groups. There was an uncomfortable problem of excluding one's own extension group in absence.

Accordingly, an object of the present invention is to provide a ring-calling method for ringing a ringing ring at the same time to a ringtone or another group when a subscriber of a plurality of key-phone telephones belonging to a ring-taking group in a key-phone system is absent.

Another object of the present invention is to exclude the extension that is on the seat / seat button on the phone of a number of extension subscribers in the ringing extension group to ring ringing ringing tone from other stations so that the other party making the call without waiting for a long time It is to provide a ring reception method to connect easily.

In order to achieve the above object, the present invention, in the keyphone system, turn off the seat / seat button of each extension to absent from the ring arrival group by ring on each extension in the ring belonging ring group is less than any number of possible extension In the case where the incoming ring rings at the same time to other extension groups and repeaters.

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

1 is a block diagram of a key phone system according to an embodiment of the present invention,

The control unit 10 controls call switching by accessing a preset program, and excludes an extension in which a ring service can be set and a number of available services are not included in the ring forwarding group. Control ring tones on the repeater. The memory unit 12 incorporates the program initial service data for performing calls and various functions, and temporarily stores data generated during program execution. The trunk line subscriber circuit 14 forms a trunk line loop by scissoring the trunk line in response to the control of the controller 10, and interfaces a signal coming from the trunk line. The subscriber subscriber circuit 16 supplies the voice current of the voice band to the subscriber's key phone and the general telephone, and performs interfacing between the extension telephone and the device. The switching circuit 18 switches various tones and voice data under the control of the controller 10. The tone generator 20 generates the various tone signals under the control of the controller 10 and provides them to the switching circuit 18. The ring generator 22 supplies a square wave shaped ring signal to the switching circuit 18 under the control of the controller 10. The DTMF transmitter 24 outputs a DTMF (Dual Tone Multi Frequency) signal under the control of the controller 10. The DTMF receiver 26 analyzes the dual tone multi frequency (DTMF) received from the subscriber of the extension subscriber circuit 16 and applies corresponding digit data to the controller 10.

2 is a flowchart for excluding a ringing extension group according to an embodiment of the present invention;

3 is a control flowchart for ring ringing to another extension group when a plurality of extensions of a ringing call group according to an embodiment of the present invention are absent.

1 to 3 will be described in detail a preferred embodiment of the present invention.

First, in order to carry out the present invention, the subscriber of the key phone system must turn on the seat / stone button provided in the phone phone, and when the seat / stone button is turned on, the ring subscriber extension group is excluded from the ringing extension group. Referring to the operation of excluding from the ring incoming extension group, the control unit 10 checks in step 101 whether the seat / seat button is pressed from the subscriber through the extension subscriber circuit 16, and if the seat / stone button is pressed, proceeds to step 102. Turn on the lamp of the seat / stone button. Then, in step 103, the controller 10 excludes the extension belonging to the ringing extension group from the ringing extension group. In other words, an extension that is turned on in the incoming ring tape is turned off from the incoming ring table. Then, in step 104, the controller 10 checks whether the seat / stone button is pressed again. If the seat / stone button is not pressed, the controller 10 returns to step 103, and when the seat / stone button is pressed, the flow proceeds to step 105. In step 105, the lamp of the seat / stone button is turned off and the process proceeds to step 106. In step 106, the controller 10 adds the extension, which is excluded from the ring-call table, to the ring-call extension group and ends the operation.

Referring to FIG. 3 to describe the operation of ringing a ringing call with another extension group when there is a ringing call in the ringing call extension group in the same state as the call forwarding / returning button in the same manner, the control unit in step 201. 10 checks whether ring incoming calls are detected from the trunk line subscriber circuit 14. If ring incoming calls are detected, the process proceeds to step 202. In step 202, the controller 10 checks whether the number of in-flight athletes who are not temporarily excluded from the landing call extension group is less than a predetermined number randomly designated by the MMC, and proceeds to step 203 if the number is not less than the specified specific number. In step 203, the controller 10 makes a ring tone to the extension belonging to the ring-destination group, and proceeds to step 205 to make a call. However, if the number is less than the specified number, proceed to step 204. If the number of members who are not temporarily excluded from the ring destination extension group is 0, the other station group and the relay station will ring at the same time. Calls are made in step 205 by ringing the call at the same time, including stations that are not excluded from the intermediary and the other ringer extension groups.

As described above, the present invention, when the seat / seat button is turned on when the key phone system is absent so that when the seat / seat button is turned on to be temporarily excluded from the ring incoming extension group is not excluded from the ring incoming extension group when there is a ring incoming When the number of unextended stations is less than the specified number, ringing tones are simultaneously ringed to other extension groups and repeaters, and thus, there is an advantage that the other party making the call does not answer the phone and can quickly connect the phone without waiting for a long time.
