Abstract

PURPOSE:To always recognize the extension terminal set being an opposite connection party to a central office line by displaying a connection destination extension terminal number of a busy central office line onto a display means of a multi-function terminal set with display means accommodated to the extension side of an exchange master set. CONSTITUTION:Suppose that a central office line No(n) and a general terminal set 11m whose extension terminal number is No(m) are connected, then a key input of a special number decided in advance is applied from a multi-function terminal set 12k with display means to input the operating state display request data of the central office line No(n). A control circuit 35 sends the connection information data of the present central office line No(n) to the multi-function terminal set 12k with display means via a multi-function terminal interface circuit 34 with display. The returned connection data is used to display information of 'COn-TELm' representing the connection of the central office line No(n) to the terminal No(m) on the display means provided on the terminal set 12k, and the operator of the multi-function terminal set 12k with the display means recognizes the connection destination terminal of the central office line No(n).

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for displaying the usage status of a central office line, and in particular, a system for displaying the usage status of a central office line, in particular, mainly accommodating a plurality of terminals in an extension line and at least one central office line in an external line, and In the switching main device that controls the connection of
The present invention relates to a method for displaying the usage status of a central office line, which displays which extension terminal the central office line in use is currently connected to.

[Conventional technology]

In main exchange equipment that accommodates multiple terminals in the extension line and at least one central office line in the external line, it displays whether the central office line is currently idle or in use; , does not display which extension terminal is currently connected.

[Problem to be solved by the invention]

As mentioned above, conventionally, it is difficult to determine whether a central office line is in use or not.
Only two states were displayed, perhaps because it was empty. Therefore, even if the central office line is in a suspended state due to, for example, a half-hanging of the hand of the extension terminal, it is difficult to distinguish it from the usage status display, and it takes a lot of time to release the central office line from a suspended state. There was a problem in that it required There is also the problem that when a central office line is occupied for a long time, the user of that central office line cannot be confirmed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a system for displaying the usage status of a central office line that solves these problems.

[Failure to solve the problem]

The office line usage status display method of the present invention accommodates a plurality of terminals in an extension line and at least one office line in an outside line, controls connections between the terminals accommodated in the extension side, and controls the connections between the terminals accommodated in the extension line side. a switching main device having a control circuit for controlling connection between a terminal housed in the extension line and a central office line accommodated in the extension line side, and at least one of the terminals housed in the extension line side is equipped with a display means. The control circuit is a multi-function terminal with a display means, and the control circuit is configured to indicate which terminal the central office line is currently connected to, which is accommodated on an extension side, by a key operation from the multi-function terminal with a display means. The feature is that the information is displayed on the display means of the multi-function terminal.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

The exchange main device 30 includes m general terminals 111, 112,
..., 11°, and k multifunction terminals with display means 12.
．． 122. ..., 12. are accommodated and connected by an extension line 10, and a plurality of outside lines 20 are accommodated and connected.

The switching main device 30 includes a central office line interface circuit 31°, a communication path switch 32. -fm terminal interface circuit 33;
It has a multi-function terminal interface circuit 34 with display means and a control circuit 35. The control circuit 35 receives call information from the office line interface circuit 31, the general terminal interface circuit 33, and the multifunction terminal interface circuit 3 with display means.
Based on call information 7 received call response information etc. from 4, connection control (call processing) of the communication path switch 32 is performed, and use state display control described later is performed.

The outside line 20 is connected to a communication path switch 32 via a central office line interface circuit 31. A plurality of general terminals IL to 11□ and a multifunction terminal with display means 12. -12 are connected to the communication path switch 32 via a general terminal ink face circuit 33 and a multifunction terminal interface circuit 34 with display means, respectively.

Next, the operation of this embodiment will be explained.

Now, there is a general terminal 11 on the extension side with the office line No. n and the extension terminal number No. m. ．． Suppose that is currently connected.

At this time, a predetermined special number is pressed manually from the multi-function terminal with display means 12k, and the central line number is entered.

Input the usage status display request data of n. This usage state display request data is sent to the control circuit 35 via the multifunction terminal interface circuit 34 with display means. Control circuit 3
5 returns the connection information data of the current office line No. n to the multifunction terminal with display means 123 via the multifunction terminal with display means interface circuit 34. With this reply connection data, the display means provided on the multi-function terminal 12 was done,
Multifunctional terminal with display means 12. For those who handle station line N
You can see which terminals o and n are connected to. Of course, if the central office line is unused (idle) at this time, "CON-
IDLE", the station line number,
You can also check the empty status of n.

〔Effect of the invention〕

The central office line usage status display method of the present invention is capable of displaying the connecting destination extension terminal number of the central office line in use on the display means of a multi-function terminal with a display means housed on the extension side of the main switching device. If the central office line becomes disconnected for some reason, for example, because the extension terminal's handset rate is halved, or if the central office line is occupied for a long time, the extension terminal to which the central office line is connected This has the advantage of being able to quickly cancel a hold situation and confirm who is using the central office line.
