JPH01265651A - Display system for busy opposite party - Google Patents

Abstract

PURPOSE:To prevent simultaneous call to same opposite destination by adding a lamp to a one-touch dial button and lighting a corresponding lamp in the case of dialing by abbreviated dial from one and same system. CONSTITUTION:When a board BD depresses a one-touch dial button, a line circuit LIN is started and a registered abbreviated dial number is sent automatically. When an exchange controller ICU receives the abbreviated dial number, an office trunk COT is acquired automatically and a destination number corresponding to the received abbreviated dial is sent to a public line, a talking start order is added to the abbreviated dial number to be called by the LCU to send the result to an interface device INFU. The INFU sends the abbreviated dial number and the talking start to all BDs and when the DB receives it, whether the dialing is sent from its own board or other board is identified and the result is displayed by a lamp. Simultaneous dialing to one and same destination is prevented by the display.

Description

[Detailed Description of the Invention] [Prior Art] Generally, when making a call to a public line in a telephone switching system, a speed dial that can be used commonly within the system is registered, and the speed dial code is dialed from the terminal's talking console or telephone. Therefore, a speed dial function is provided that automatically sends out the destination dial.

In some cases, a terminal has a one-touch dial function, in which multiple buttons are provided on the talk stand or telephone set, speed dials are registered in the buttons, and pressing the button automatically calls the other party. (Tokukosho [Problem to be Solved by the Invention]) However, when making a call using these functions, the terminal in the system does not display the destination of the call, so there is a possibility that calls may be made to the same destination at the same time. It is only after dialing the other party that you know that the other party is busy.

There were also problems such as not being able to tell even if the person on the other end of the call was talking within the own system.

[Means to solve the problem]

The present invention is intended to solve these problems by adding a lamp to the one-touch dial notification, so that when a call is made using speed dial or one-touch dialing from within the same system, the corresponding lamp is lit to send a call to the same destination. This prevents simultaneous transmission of .

Furthermore, by color-coding the lamps depending on whether the call is made in confession or the call is made in lieu, it is possible to know at a glance which party is making a confession call.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, BD is a telephone desk LIN is a line circuit, LCU is a switching control device, CUT is a central office line trunk, INFU is an interface device between BD and LCU, and MP is a maintenance panel.

Speed dials used in the system are registered in advance by the maintenance panel.

The HD has one button for one-touch dialing, and the system speed dial number of the other party is registered for each button.

When you press the one-touch button on the HD, l, IN is activated and the registered speed dial number is automatically sent.

When the LCU receives the speed dial number, it automatically dials C.
It captures the OT and sends the received destination number compatible with speed dialing to the public line. At the same time, the LCU adds a call start order to the dialed speed dial number and sends it to INFU.
Send to.

INFU sends the speed dial number just dialed and a call start order to all BDs.

When the BD receives a speed dial number and a call start order, it identifies whether it is a confession call or a trial call and displays a lamp.

When the BD is restored after the call ends, the LCU sends the speed dial number and call end order to the INFU.

INFO sends a speed dial number and end call order to all BDKs.

When the HD receives this information, it decreases the corresponding lamp.

The above is for a one-touch call, but the same operation occurs when a speed dial call is made.

〔Effect of the invention〕

According to the invention, when a call is being made using speed dial or one-touch dial within the same system, the call status is displayed on all terminals in the system, which has the effect of preventing simultaneous calls to the same destination. .

Claims (1)

[Claims] 1. In a telephone exchange system, when multiple telephone consoles are equipped with buttons for one-touch dialing of public lines, and one-touch dialing or termination is made from any of the telephone consoles, a call is started to the speed dial number issued by the exchange control device. A system for displaying a party during a call, characterized in that a signal to which an order or a call termination order is added is received by all of the talking consoles via an interface device, the call or the call termination is identified, and a lamp is displayed.
