Abstract

PURPOSE:To attain displaying the number of the calling terminal at the called terminal without increasing the load on the central processing unit by storing each terminal information in the subscriber's circuit that controls the terminals. CONSTITUTION:When a terminal 111 is calling a terminal 121, the dial tone is received by a subscriber's circuit 110 to which the calling terminal belongs. At this time, a microcomputer 200 in the circuit 110 reads out the terminal information from a storing circuit 202, and transmits it to the call signal reception line 122 of the subscriber's circuit to which the called terminal belongs via a terminal information transmit circuit 203. Meanwhile, the called subscriber's circuit 120 receives the calling terminal's information sent to the reception line 123 by its terminal information reception circuit 204. The information is transmitted to the terminal 121 via a terminal control interface circuit 206, and displays the number of the calling terminal for the terminal 21.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for transmitting calling terminal information in an electronic exchange;
More specifically, the present invention relates to a method for transferring calling party information to be displayed on a called terminal to a called terminal without going through a central control unit.

(Prior art) Conventionally, if this type of calling side information is simple information such as a terminal (telephone) number, a central control unit reads the terminal information stored in correspondence with the accommodation location and controls the called side terminal. Each time a connection was made, the terminal information of the calling party was transferred to the subscriber circuit and displayed.

(Problems to be Solved by the Invention) Therefore, if there is a large number of terminal information or terminals on one calling party, the processing by the central control unit becomes enormous.

The disadvantage is that the processing capacity is reduced.

Purpose of the Invention When connecting arbitrary terminals, when displaying calling side terminal information on the called side terminal, the subscriber circuits controlling the terminals can directly communicate with each other via a communication path without going through a central control unit.

A terminal information transmitting circuit that transmits the terminal information stored in the memory circuit to the communication path, and a terminal information receiving circuit that receives the terminal information sent from the connection destination. During connection, while the called terminal equipment is being called, the terminal information stored in the calling side storage circuit is transferred from the calling side terminal information sending circuit to the called side terminal information receiving circuit via the communication path. The device is configured to display the calling terminal information on the called terminal.

According to the above configuration, since the central control unit is not used, the processing capacity of the central control unit does not deteriorate, and the object of the present invention is completely achieved.

Further, a call signal transmission line 122 from the subscriber circuit 120
and the call signal receiving line 113 to the subscriber circuit 110. The audible sound generating circuit 131t is connected to the call signal receiving line 113 to the subscriber circuit 110 on the calling side, and the ringing tone is transmitted through the call signal receiving line 113 to the call signal receiving line 113.
14 to terminal I'll.

On the other hand, the called subscriber circuit 120 connects the calling signal 130 to the first terminal communication line 124 and puts the terminal 121f into a calling state.

FIG. 2 shows subscriber circuits 11G and 120 according to the present invention.
FIG. 2 is a circuit block diagram showing one embodiment of the present invention.

The subscriber circuits 110 Th and 120 are a microcomputer 200, an OPU IP-Y IP circuit 201, a storage circuit 202, a terminal information sending circuit 203, a terminal information receiving circuit 204, a terminal communication interface circuit 205, and a terminal control interface Oo path. and relay R2
It consists of 1G, 211, and 212.

The microcomputer 200 (LP) controls the inside of the subscriber circuit and the terminal. The terminal 224 is connected to the control signal bus 102 shown in FIG. 1, and the microcomputer 200 can communicate with the central control unit 101 via the OPU interface circuit 201.

2G? a microcomputer 2000 control signal line bus (LP-BUS), and a storage circuit 202 stores information regarding terminals controlled by the subscriber circuit.

As explained in FIG. 1, the terminal 111 makes a call and the terminal 121
, the calling side subscriber circuit 110 receives the ringing tone via the call signal receiving line 113t-.

This call signal receiving line 113 is connected to a terminal 223 in FIG. At this time, relay Rzxt is connected to call receiving line 2.
It has been switched to the 09 side (dotted line side), and relay B
212 is also switched to the terminal call interface circuit 205 side (dotted line side), so the ringing tone received via the terminal 223 is transferred to the terminal 220 via the relay Rztx - call reception line 209 - terminal call interface circuit 205 - relay R212j - sent to.

Terminal 220 is connected to terminal communication line 114, and terminal 111 hears the ringing tone.

The message is sent to the terminal communication line 124 via the terminal 121, thereby placing the terminal 121 in a calling state. Also, since the microcomputer 200 simultaneously switches the relay IFL 211 to the terminal information receiving circuit 204 side (solid line side), the calling side terminal information sent to the call signal receiving line 123 is transferred to the terminal information receiving circuit via the terminal 223. It is received at 204. Here, the microcombiator 200 reads the received calling side terminal information from the information receiving circuit 204, converts the information into a control format for the display of its own terminal, etc., and then sends the information to the terminal 221 via the terminal control interface circuit 206. Sends control signals to. Since the terminal 221 is connected to the terminal control signal line 125 in FIG. 1, this control signal is transmitted to the terminal 121 and displayed.

Note that when the called party answers, the information is sent to the central controller 10.
1, the central controller 1°01 instructs each subscriber circuit to set the call status, and connects the reserved line of the time-division call path Zoo.

In this manner, all relays in the subscriber circuit are switched to the communication path side, and the terminal information sending circuit and receiving circuit are separated from the communication path.

(Effects of the Invention) As explained above, the present invention stores each terminal information in the subscriber circuit that controls the terminal as follows, and when the called terminal is being called, the called subscriber circuit By transferring the calling terminal information to the side subscriber circuit via the communication path, there is an effect that the terminal information can be displayed without increasing the burden on the central control unit.
