Furthermore, the dial number re-sending means 40 to read out the extension number of the outgoing side terminal from the re-sending dial number registration means 42 and to issue the outgoing based on the number is provided. Thereby, it is possible to issue the outgoing to the caller with the simple operation by the callee receiving the incoming after disconnecting the line.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dialed number retransmission system for an electronic exchange. The dialed number was automatically registered in the retransmission dial number storage area in the main memory, and even if the line was once disconnected, the caller could easily make the call again by performing a predetermined operation. .

[Problem to be solved by the invention]

However, after the line is disconnected, the called party cannot make a call to the caller with simple operations, and if it is necessary to make a call to the caller, it is necessary to confirm the caller's phone number in advance. It was necessary to dial the caller's phone number. Therefore, it is troublesome, and there is also a possibility that a call may be made by mistake due to a confirmation error or an erroneous operation.

The purpose of the present invention is to solve such problems and to provide a dial number retransmission system for an electronic exchange that allows the called party who receives a call to make a call to the calling party with a simple operation after disconnecting the line. Our goal is to provide the following.

[Means to solve the problem]

The present invention provides a dial number retransmission system for an electronic exchange having a retransmission dial number storage area in a main storage device, comprising: 19 means for storing an extension number of a terminal; and storage means for storing an extension number of a calling terminal in the storage means. registration means; retransmission dial number registration means for reading the extension number of the calling terminal from the storage means and storing it in the retransmission dialing number storage area when a predetermined operation is performed on the receiving terminal; and the receiving terminal. When a predetermined operation is performed, the telephone number retransmission means reads the extension number of the calling terminal from the retransmission dial number registration means and makes a call based on that number.

〔Example〕

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

FIG. 1 is a block diagram showing an embodiment of an electronic exchange using the dial number retransmission method of the present invention.

The main switch 10 has terminals 21.22 connected to its terminals A and B through line circuits 20, and a register 30 for storing the extension number of the terminal 21.22.
are connected, and the main switch 10 connects these terminals 21.
22. Interchangeably connect the registers 30 to each other. The central control device 40 is connected to the line circuit 20, the register 30, and the main storage device 50, exchanges data information among them, and controls exchange of the main switch 10.

Then, the central controller 40, as shown in FIG.
It includes a request analysis section 41 and a retransmission dial number registration means 42 realized by software.

The main storage device 50 is provided with an extension number storage area 52 and a retransmission dial number storage area 53 corresponding to the line position 51 as terminal data storage areas. In the extension number storage area 52, extension numbers are registered in advance by a maintenance person or a driver in correspondence with the line positions 51, that is, terminals A, B, . . . .

Table 1 shows the special dial numbers (special numbers) used in this electronic exchange and their corresponding functions.

Table 1 Next, a call arrives from terminal 22 to terminal 21, and after the line is disconnected,
The operation will be explained using an example where a call is made from the terminal 21 to the terminal 22. When the terminal 22 sends a call to the terminal 21, the central controller 40 controls the main switch 10 and the line circuit 20,
When the terminal 21 responds to the incoming call, a communication path is formed between the terminals 22 and 21. The central control unit 40 further acts as a registration means and registers the extension number "56" of the calling terminal 22.
78” is stored in the register 30.

The called party on the terminal 21 side receives a predetermined retransmission dial number registration special number "99°" during the call state or after the call ends.
Dial. Here, the request analysis section 41 of the central control device 40 analyzes the operation on the terminal 21, and if it is identified as a "resend dial number registration" request, the resend dial number registration means 4
Start 2. As a result, the registration means 42 registers the register 3
The extension number "5678" stored in 0 is read out and stored in a predetermined area of the retransmission dial number storage area 53 that corresponds to the terminal 21 and corresponds to A of the line position 51.

Next, after the line is temporarily disconnected, when the retransmission dial special number "00" is dialed at the terminal 21 to make a call to the terminal 22, the central control unit 40 operates as a dialed number retransmission means and analyzes this operation. The retransmission dial number storage area 53 identifies that the request is for retransmission dialing.
extension number "567" from the area of the retransmission dial number storage area 53 corresponding to the terminal 21 in the line position 51.
8'' is read out and a call is made to the terminal 22 based on this number.

That is, with this electronic exchange, the called party who receives the call can simply dial a special number, disconnect the line, and then make a call to the calling party.

〔Effect of the invention〕

As explained above, the present invention provides a dial number retransmission method for an electronic exchange having a retransmission dial number storage area in the t9 device, a storage means for storing the extension number of a terminal, and a storage means for storing the extension number of the calling terminal. a retransmission dial number registration means for reading the extension number of the calling terminal from the storage means and storing it in a retransmission dial number storage area when a predetermined operation is performed on the receiving terminal;
When a predetermined operation is performed on the called terminal, dialed number retransmission means is provided which reads the extension number of the calling terminal from the retransmission dialed number registration means and makes a call based on that number.

Therefore, according to the electronic exchange using the dial number retransmission system of the present invention, the called party who receives an incoming call can make a call to the calling party with a simple operation after disconnecting the line.
