Abstract

PURPOSE:To efficiently contrive the operation of a line by providing an incoming index to a 2nd line fixed to a terminal equipment independently of a trunk type index to a trunk class data and connecting the line with the priority of the incoming index so as to use the 2nd line by sharing all terminals as a 1st line at an origination. CONSTITUTION:A DIL index 16 being an incoming index to the 2nd line is provided to the trunk class data of central office line trunks BWT11 - BWT13 independently of the trunk classification index 15 and when the content of index 16 is '1', it represents to be an incoming call to the line DIL. When an incoming call comes to the central office line trunks BWT11 - BWT13, a controller CC6 decides the call to the BWT13 to be the call to the line DIL, thereby connecting the BWT13 and the line DIL. Moreover, in depressing the button L3 of optional multi-functional telephone sets EK11 - EK13, the BWT13 is acquired according to the trunk classification index of the trunk class data and enabled for the origination. That is, the line fixed to a terminal equipment is used by a multi-functional telephone set.

Description

[Detailed Description of the Invention] [Summary] A first line that is shared by multiple terminals, and a second line that is fixed to the terminal and that receives calls from the office line directly only to the corresponding terminal.
In the line connection method of a private branch exchange equipped with a line, the trunk class data includes an incoming call indicator to the second line that is independent of the trunk type indicator, and this incoming call indicator is given priority when connecting the line. The second line can also be used as the first line that can be shared by all terminals when making a call.

[Industrial application field]

The present invention relates to a line connection system, and particularly relates to a connection system between a first line shared by a plurality of terminals and a second line fixed to the terminal.

For the line connected to the private branch exchange, one central line is used as the first line shared by multiple terminals, and one line corresponds to one of the multiple buttons on the multi-function telephone, allowing calls to be made to the central office line and calls to the central office line. There is a line used for operation by pressing a corresponding button (so-called direct line method), and a second line that directly calls a predetermined terminal in response to an incoming call from the central office line. Since there are lines used for the operation method (so-called direct inline method), it is necessary to operate these lines efficiently.

[Conventional technology]

FIG. 4 shows a configuration diagram of an example of a conventional line connection system. In the figure, EKl, EK2 and EK3 are each multi-function telephones, each having a plurality of (in this case two) variable function buttons L+,
It has L2 and a lamp (not shown) corresponding one-to-one. Each button 1 of the multifunction telephones 11EKI to EK3 is commonly connected to the office line trunk BWT1 via the line DL1, and the button L2 is commonly connected to the office line trunk BWT2 via the line L2. .

On the other hand, S+ is a general black telephone (601 苧 telephone) and has a telephone ID.
It is connected to the office line trunk E3WT3 via IL. Furthermore, since a black telephone interface is required for incoming calls to the facsimile F1, the facsimile F1 is connected to the office line trunk BWT3 via the line DIL.

In this state, the central office line trunks BW'r1 to BW-r

You can respond by pressing . In addition, in the case of an incoming call from line DIL, it is directly sent to black phone S1 and facsimile F.
1 and can be answered simply by lifting the handset of the black telephone S1.

[Problem that the invention seeks to solve]

In the conventional line connection method, lines D L 1 and D
L2 and line DIL are treated as separate and independent lines, and line DIL that accommodates facsimile F1 and black telephone S1 cannot be used as line DL.

Therefore, the facsimile F1 is the multifunction telephone EK1 to EK.
Although line DIL is generally used less frequently than line 3 and has a high percentage of line DIL being vacant, line DIL is a multi-function phone.
It could not be used for transmission by EK1 to EK3, and its usage efficiency was poor.

The present invention was created in view of the above points, and an object of the present invention is to provide a line connection system that allows a fixed terminal line to be shared with a remote terminal for use when making a call.

[Means for solving problems]

The line connection method of the present invention provides a first line connection system that is shared by multiple terminals.
In the line connection system of a private branch exchange, which is equipped with a line and a second line fixed to the terminal, in which incoming calls from the central office line are directly transmitted only to the corresponding terminal, the second line is It detects whether there is an incoming call on the line, connects the line with priority given to incoming calls on the second line, and when making a call, the second line is shared by all terminals as the first line. be.

[Effect]

The trunk class data has an indicator of incoming calls to the second line that is independent of the trunk type indicator, and based on this incoming call indicator, when an incoming call is received, it is first determined whether the call is incoming to the second line or not. It is checked whether or not.

If the incoming call is to the second line, the predetermined terminal and the second line are connected. If the incoming call is not to the second line, connections are made between a plurality of other terminals and the first line.

In use, when making a call, the second line is shared by all terminals as the first line. The reason why the second line is not used as the first line when a call is received is that if this is done, it will not be possible to determine whether the call is received on the second line.

(Embodiment) FIG. 1 shows a configuration diagram of an embodiment of the present invention. In the figure, the same components as in FIG. 4 are given the same reference numerals. In FIG. 1, each of the multifunction telephones 11EK1 to EK3 has 3
It has two buttons 11 to [3, respectively. BW711~
13 are central office line trunks each having a built-in microbrochure. In addition, 5 is a switch, 6 is a control device (CC),
7 is a memory device (MM).

In a private branch exchange with such a configuration, the central office line trunk BWT

4 to the second line, independent of the trunk type indicator 15.
A DIL index 16, which is a reliability index, is provided, and is also composed of various other data. For example, when the value of the DIL index 16 is V □ t, it is not an incoming call to line OIL, but vl
When the value is v, it indicates that the call is received on the line DIL.

Therefore, in step 10 above, the central office line trunk B

When the value of 6 is 717, it is determined that the trunk BWT 13 is incoming to the line aD[L, the DIL incoming 8M side is activated, and the connection between the trunk BWT 13 and the line DIL is performed.

(Step 11 in Figure 2). In addition, in this case, for example, a message "In use by others" is displayed at the positions corresponding to the buttons L3 of the multifunction telephones EKI1 to EK13.

On the other hand, in step 10 above, the DIL index 16
If it is detected that the value of Di - Incoming call mechanism 13

).

In this manner, when a call arrives, it is determined preferentially whether or not the call is to the line DIL fixed to the terminal, and the line is connected.

Next, to explain the operation when making a call, the multi-function telephone EK
11 to EK13, when you press the button L1 or L2 whose lamp is off on any multi-function telephone, the corresponding trunk BWTII or BWT1 is connected.
It is connected to the line via 2.

Furthermore, when the button L3 of any of the multifunction telephones EK11 to EK13 is pressed, the office line trunk BWT13 is captured according to the trunk type index of the trunk class data, and a call can be made. In other words, the line fixed to the terminal can also be used by a multifunction telephone.

On the other hand, calls from the black telephone S1 or the facsimile F1 can be made via the office line 1-rank BWT13, as in the conventional case. Therefore, when making a call, the terminal-fixed line DIL can be used by all terminals.

This makes it possible to effectively utilize the line DIL, which has a low usage tendency.

Note that the present invention can also be applied to a system that uses a computer terminal or a computer main body instead of the facsimile F1.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to use both a fixed terminal line and a line shared by multiple terminals when making a call. can be shared between devices,
This system has features such as being able to operate the line efficiently without adopting a new incoming call/outgoing method.
