The present invention relates to a branch office incoming branch (branch) in a key phone system, in particular, when a subscriber using a key phone system is ringing a branch office incoming ring to another station, picking up a handset, the branch office branch in a key phone system where the trunk line is incoming It relates to the operation method, the following problems arising from the general CO line incoming method, that is, if the subscriber to the key phone phone, pick up the handset and press the corresponding CO line button, or if you are a regular phone subscriber, pick up the handset dial '*' button or ' By pressing the # 'button to answer the substitute phone phone or ordinary telephone to pick up the handset and another button hassle, the present invention provides a branch office call branch (branch) for the trunk line desired by the subscriber using the key phone system To be able to select whether or not to use, and accordingly the CO line to other station To ensure that the subscriber is the called trunk branch (branch) function assigned to the handset such that the incoming CO ring when there are new sounds, especially very convenient for ordinary telephone subscribers.

Description

The present invention relates to a trunk line incoming branch function in a key phone system. In particular, when an incoming signal comes to an external trunk line in an office that mainly uses a key phone system, a ring of a telephone to which a trunk line is designated is ringing, and a destination line is not designated. If you designate an incoming branch function for the CO line to other station subscribers, the ring will ring only on one phone, but other station subscribers nearby will also pick up the handset to receive the corresponding CO line. When the designated ringing line is called only by the designated ringing phone, and other phones have the same extension group as the ringing ringing phone, the handset is picked up and the dial * or # button is increased to allow the incoming call.

In general, the key phone system is configured as shown in FIG.

A controller 1 for managing and controlling all functions of the key phone system; A memory section 2, comprising a program memory (ROM) 2A and a data memory (ROM) 2B, which stores contents necessary for system operation; A data communication unit 3 which notifies the control unit 1 of the state of the trunk line and the station and transmits the information sent from the control unit 1 to the trunk line and the station; It consists of a matrix unit 4 for transmitting and controlling voice and various signals between the trunk line and the station or between the station and the station.

In this case, the key phone system is generally configured in three modes. These include the normal mode, which is the normal mode in which the key phone system is normally used, the state of the telephone in the system when the key phone system is installed, i.e., the ring signal is audible, and the light emitting diode of the button Test Mode to test whether LED) is working or the characters are displayed on the LCD, and the program contents that are initially set to meet the needs of the user, that is, the ring signal. It consists of Program Mode to change and operate the presence or absence. At this time, if there is a mode conversion switch in the phone, the switch operates in the normal mode if the switch is in the position of 'N' (Normal Mode), and the switch is in the 'T' (Test Mode) terminal. When in position, it operates in test mode. When the switch is in position of 'P' (Program Mode), it operates in program mode.

The general CO line incoming method in the key phone system configured as described above rings when an incoming signal arrives at a CO line and rings at one or more stations (hereinafter referred to as 'extension A') designated by the CO line. In Station A, you can receive a call when you pick up the handset, but in another station where the ring does not ring (hereinafter referred to as Station B), hold the handset and press the dial '#' button. If 'is designated as the same group, the incoming call is received. Otherwise, the incoming call is not received.

In order to compensate for this problem, the present invention has added a trunk line incoming branch function so that a trunk line can be received by lifting a handset for the trunk line for each station subscriber. Therefore, it is possible to program the incoming / outgoing branch function for the CO line required by each subscriber, so that only one phone can be assigned to one phone line so that the ring rings. Incoming calls were made for ease of use while creating a pleasant office atmosphere.

In addition, the present invention allows the subscriber using the key phone system to select whether to use the trunk line incoming branch (branch) function and the trunk line to be used, accordingly, the incoming branch function to the designated trunk line When a signal is received, it is characterized in that the corresponding CO line is received by lifting the handset. That is, the first step of programming if you want to designate and release the branch line destination (branch); When the incoming call signal of the corresponding trunk line is received from the telephone set to which the trunk line incoming branch function is designated, a second step is performed in which the corresponding trunk line is received by lifting a handset.

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

2 is a flowchart illustrating the operation of designating / releasing a branch office call branch in a key phone system of the first step of the present invention.

First, the mode state of the key-phone telephone is changed to the program mode, and then the 'hold' button and the call destination designation dial, for example, '75', are designated to designate the call destination branch field (step S1). In this case, the C.O RING BRANCH, which is an indication that a trunk line incoming / outbound branch field can be designated, is displayed on the LCD. Then, press the extension button to be designated (step S2). In this case, the station number designated as STA: 200 is displayed on the liquid crystal display (LCD), the designated station lamp is lit, and the trunk line lamp which is already designated with a call branch in the designated station is lit. Then, the CO line button to be designated is pressed (step S3). It is determined whether or not the designated trunk line is assigned to the selected station (step S4). If the designated branch line is designated, the incoming branch function of the corresponding trunk line is canceled. It is specified (step S5). At this time, when the incoming branch function is released, the CO line lamp that is turned off is turned off. When the incoming branch function is designated, the CO line lamp is turned on to indicate that the designated CO line lamp is turned on. At the selected station, it is determined whether to continue designation for another trunk line (step S6), and if it is to be continued, the process returns to step S3 and repeats the above steps (steps S4, 5, 6). If it is determined whether to continue designation for another station (step S7), if it is to continue, it returns to step S2, repeats the steps (steps S3, 4, 5, 6, and 7), 'Button to release the C.O. branch designation field (step S8). Finally, the mode state of the key-phone telephone is changed to the normal mode (step S9).

3 is a flowchart illustrating the operation of trunk line incoming, which is the second step of the present invention.

When an incoming signal arrives at the CO line, the ring rings at 'EXT A' where the CO line is designated (step T1). Station B, designated with a call destination branch function for the CO line, picks up the handset (step T2). Station B listening to the handset determines whether the incoming branch function is designated for the CO line (step T3), and if so, the ring stops and the CO line is received (step T4).

As described above, according to the present invention, when the subscribers who use the keyphone system make a ringing call, only one station is designated to ring, and then the other stations designate a branching call branch function to pick up the handset. By making the incoming calls, you can create a pleasant atmosphere in offices that use the key phone system. Especially, it is more convenient when you use a general telephone without a button and a lamp.
