Abstract

PURPOSE:To transmit audible tone information to a subscriber circuit without increasing the processing of a CPU by transferring the audible tone information to the subscriber circuit through a main channel network together with an audible tone. CONSTITUTION:When the audible tone is transmitted to a terminal 104, the CPU101 controls a switch 100 through a bus 112 to connect a sound signal line 110 and a connection signal line 111 between an audible tone generator 102 which generates the necessary audible tone and the subscriber circuit 103. Consequently, the audible tone of the generator 102 is sent to the terminal 104 through the signal line 110 and circuit 103. At the same time, the audible tone information sent out of an audible tone infornation sending circuit 105 where specific data is set according to the kind of the audible tone is transmitted to an audible tone information receiving circuit 106 through the signal line 111 and circuit 103. Then, the information received by the circuit 106 is read by a subscriber circuit processor 107 which controls the circuit 103 and the audible tone information is displayed through a control circit 113 according to the information.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for transferring terminal display information in an electronic exchange.

Conventionally, audible sound transmission information for displaying the audible sound transmission status on this type of terminal is transferred between a central control unit and a subscriber circuit that controls the terminal to which the user wishes to listen. This system controlled the main channel network to connect the audible sound generation circuit that generated the audible sound, and at the same time transferred this audible sound information to the subscriber circuit each time the audible sound was transmitted and displayed it on the terminal. .

Therefore, the more terminals there are with display functions, the more processing the central control device has to perform, creating a greater burden.

Particularly when audible sounds have to be sent to a large number of terminals, a delay in sending occurs, which is a big problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide an audible sound information transfer system that reduces the processing amount of a central control unit and greatly reduces the burden on the central control unit.

In order to achieve the above object, the audible sound information transfer system according to the present invention connects an audible sound generation circuit that generates various audible sounds and a subscriber circuit through a main channel network, and transmits the information to a terminal by the subscriber circuit. In an audible sound information transfer method in an electronic exchange that controls to display the audible sound transmission status,
The audible sound generation circuit is provided with an audible sound information sending circuit that sends identification information of various audible sounds, and the subscriber circuit is provided with an audible sound information receiving circuit that receives the audible sound information. The main channel network is configured to be able to simultaneously transmit a voice signal and a connection information signal, and configured to transmit audible sound transmission information from the audible sound generation circuit to the subscriber circuit together with the audible sound. .

According to the above configuration, the burden on the central control unit regarding the transmission of audible sounds can be reduced, and the object of the present invention can be completely achieved.

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

FIG. 1 is a block diagram showing an embodiment of an electronic exchange to which the audible information transfer method according to the present invention is applied.

In the figure, 100 is a main channel network (hereinafter referred to as "SW") that can connect audio signals and connection information signals at the same time, and 102
104 is a terminal with a display function, 103 is a subscriber circuit (hereinafter referred to as LO) that controls the terminal 104, and 101 is a central control unit (hereinafter referred to as LO).
(hereinafter referred to as "CPU").

If it is necessary to make the terminal 104 listen to audible sound, the CPU
101 is s w io via a signal line 112 .

TGU 102 and L that control the
An audio signal line 110 and a connection information signal line 111 are connected to O103.

As a result, the audible sound of the TGU 102 is transmitted through the audio signal line 110,
It is sent to the terminal 104 via the LO 103.

At the same time, audible sound information sent from the audible sound information transmitting circuit 105 in which specific data is set depending on the type of audible sound is transmitted to the audible sound information receiving circuit 106 of the LO 103 through the connection information signal line 111.

The audible sound information received by the audible sound information receiving circuit 106 is L.
Subscriber circuit processor (hereinafter referred to as ""L") that controls O103
OP'') 107 reads the information, and causes the terminal 104 to display audible sound information via the terminal control line 113 in accordance with the information.

As described above, without the OPU 101 transmitting audible sound information to the LOP 107 via the signal line bus 112,
The terminal 104 can listen to an audible sound and at the same time perform a display corresponding to the audible sound.

As described in detail above, the present invention provides an audible sound information sending circuit in the audible sound generation circuit, and transmits the audible sound information together with the audible sound to the subscriber circuit via the main channel network, thereby controlling the central control unit. The advantage is that audible information can be conveyed to the subscriber circuit without increasing processing.
