Abstract

PURPOSE:To develop a calling party information, and to connect a specified called terminal to a calling terminal by checking a command display flag of a terminal state storing circuit, when a calling party instructs a response to the specified called terminal by a voice or a dial in the course of a dispatching command. CONSTITUTION:A controlling circuit 5 is connected to a digital time division channel 4 of a dispatching command system, a call connection is executed by the circuit 5 by a dispatching command service request of a calling terminal 7, and also a command indicating flag and a calling party information are set to a terminal state storing circuit 6. Also, a digital receiving circuit 10 is connected to a divided channel 4, and a response instruction of the calling terminal 7 is executed by a voice or a dial to a called party terminal 8c. Subsequently, basing on an information received by the receiving circuit 10, a flag of the circuit 6 is identified by the circuit 5, and thereafter, the specified called party terminal 8c is connected to the calling terminal 7.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention employs a simultaneous command system in a digital time division switch.

The conventional simultaneous command service, which connects one calling terminal and multiple called terminals using a digital time-division switch, is based on a call sent by a multiplex circuit 1 at time t2, as shown in Figure 1. Call terminal output a is connected to digital switch Sakae DsW
2 causes tl, t3. ts, 'ts..., and the disassembly circuit 3 sends it to multiple called terminals, so that the flow of information is one-way from the calling party to the called party. It has become. Therefore, there is a drawback that the calling party cannot confirm the response of the called party.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks and to provide a simultaneous command system that allows a calling party to confirm the response of a called party.

In order to achieve the above object, the simultaneous command system according to the present invention is a simultaneous command system in a digital time division switch that connects a calling terminal and a plurality of called terminals by means such as special number dialing of the terminal. A terminal status storage circuit is provided to store a command display flag and caller information during call connection processing, and when the caller instructs a specific called terminal to respond by voice or dial during the above-mentioned simultaneous command, By checking whether there is a command display flag in the terminal status storage circuit by the response instruction or by the response made by the particular called terminal by means such as 7-tucking, and then expanding the calling party information, The device is configured to connect the specific called terminal to a calling terminal.

With the above arrangement, the calling party can input the information of any called party while sending information to a plurality of called parties, and the object of the present invention is fully achieved.

Hereinafter, the present invention will be explained in more detail with reference to the drawings and the like. FIG. 2 is a diagram for explaining an embodiment of the simultaneous command system according to the present invention. In FIGS. 2(a), (b), and (c), 7.8a to 8d are terminals, 9 is an audible sound circuit, 5 is a control circuit, and 6 is a terminal state storage circuit, respectively. Assume that terminal 7 is a calling terminal, terminals 8a to 8d are called terminals, and 80 is a called terminal that requests a response. When the terminal 7 requests a simultaneous command service to a plurality of terminals 83 to 8d by means such as special number dialing, the control circuit 5 performs call connection using the same method as in FIG. 1 (FIG. 2(a)). Along with this process, the control circuit 5 also sends a command display flag indicating that a simultaneous command has been issued to the terminal status storage circuit 6 and caller information indicating the calling terminal. do. In this state, when the calling terminal 7 instructs the called terminal 8c to respond by voice, the called terminal 8C responds by means such as hooking. After the control circuit 5 identifies the command display flag in the terminal status storage circuit 6 based on the response of the called terminal 8c, it expands the calling party information and performs connection processing to the calling party (second
Figure (C)). After the above connection processing, the calling terminal 7 can listen to the voice of the called terminal 8c. Similar procedures can be used to connect other called terminals, making it possible to confirm responses from all called terminals. After confirming the response, the calling party restores the connection from the called party by means such as hooking, thereby returning to the original state shown in FIG. 2(a).

FIG. 3 is a diagram for explaining another embodiment of the present invention. In FIGS. 3(a), (b), and (c), parts that have the same functions and roles as those in FIG. 8a to 8d are called terminals, and 8C is a called terminal instructed to respond. Also 1
These are a 0-digit digit receiving circuit and an 11-digit DT circuit. The control circuit 5-digit second
As in the case shown in the figure, the call connection process is carried out, and the command display flag and caller information are set in the terminal state storage circuit 6.

In this embodiment, a digit receiving circuit 10 is provided, and the calling terminal 7 is instructed to respond by dialing the number of the called party to the called terminal 8c. Therefore, the control circuit 5 performs the same control as in the case of FIG. 2 based on the information received by the digit receiving circuit IO, and connects the called terminal 8c to the calling terminal 7 (FIG. 3 (C
)).

In this embodiment, as is clear from the above explanation, all processing operations can be performed by the calling party.

In FIG. 2.3, a process for connecting the audible sound circuit 9 to the called terminal 80 for a certain period of time can be inserted before the called terminal 8c and the calling terminal 7 are connected.

This is effective for easily determining that the called terminal has received a response instruction.

As explained in detail above, according to the present invention, it is possible to listen to the voice of any called terminal during a simultaneous command, so that
Qi command time! This has the effect of confirming the response of the Ir called party.
