Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a data exchange system between telephone exchanges.

The present invention is utilized in a circuit for transmitting and receiving ticket data exchanged between exchange boards.

〔overview〕

The present invention is a ticket data transfer method for tickets exchanged between exchanges including switchboards, in which a special number is issued to enable a central processing unit of a called party to be sent to a central processing unit of a called party via an interoffice line at a calling party's switchboard. By simulating a pseudo switchboard that can be operated, it is real-time, does not require a dedicated line, and requires less memory capacity.

[Conventional technology]

If there is a switchboard in each telephone exchange between generally correlated telephone exchanges (for example, between international exchanges in the same country, or between a parent office and a slave office), the ticket content of the call that goes through the switchboard. The terminals search for each other, or take the ticket received at the slave station and take it back to the master station, which then processes the call connection.

In this case, the conventional method of exchanging ticket information that is independently managed by each station has been the Haggi method.

Normally, tickets are stored in the memory of the exchange system, but the contents are dumped onto a magnetic tape or disk at regular intervals, and this medium is exchanged between both stations, allowing each station to transfer information from the other station to their respective systems. There is a way to incorporate it.

However, this method has poor real-time performance and cannot always maintain the latest information.

In order to solve this lack of real-time performance, there is a method in which dedicated data equipment and data lines are installed between exchanges, ticket information is constantly exchanged, and ticket information of the other station is stored in the memory within the own station. is taken.

- [Problem to be solved by the invention] However, the above-mentioned method has poor real-time performance, or even if this point is improved, it reduces the processing capacity of the system and puts pressure on the effective use of memory. However, there were disadvantages such as the need to install an expensive dedicated line.

It is an object of the present invention to solve this drawback and provide a ticket data transfer system for an exchange that is real-time and does not require a dedicated line.

[Means for solving problems]

The present invention provides a ticket data transfer method for a switchboard in which a switchboard is installed in a plurality of switchboards, and ticket information for the switchboard is exchanged between the switchboards of the plurality of switchboards. means for transmitting a special number at the terminating station, capturing the pseudo switchboard using the special number from the terminating station, and connecting the switchboard at the originating station and the pseudo switchboard at the terminating station via an inter-office line; Inside the switching board of the originating station, there is a means for switching an internal control circuit from the central processing unit side of the originating station to a communication circuit for the switching board, and a means for switching the internal control circuit from the central processing unit side of the originating station to a communication circuit for the switching board, and a means for switching the key information from the operator of the switching board for the originating station to the internal control circuit and the above. A means for transferring the received key information to the pseudo switchboard of the receiving station via the communication circuit for the switchboard and the above-mentioned inter-office line, and the pseudo switchboard transfers the received key information to the receiving station as if the operator at the own station operated the key. means for transmitting the response information to the central processing unit of the receiving station;
The present invention is characterized by comprising means for transferring the response information from the pseudo switching board to the switching board of the originating station via the inter-office line, and displaying the response information on the switching board of the originating station in accordance with the response information.

In other words, the present invention provides a ticket data transfer system for switchboards in which a plurality of exchanges mutually exchange ticket data, which is captured by a special number transmitted by the calling party, and centrally communicated to the called party in response to the key information sent by the calling party. A pseudo switchboard that transfers the response information of the processing device to the calling party is simulated,
This pseudo switchboard, the central processing unit on the called side, and the switchboard on the calling side are connected via an inter-office line.

[Effect]

In a pseudo switchboard that is simulated on the called side by instructions from the calling side, if the calling side's switchboard and the called side's central processing unit are connected via an interoffice line, the calling side This makes it easy to grasp the ticket data of the called party in real time.

〔Example〕

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

FIG. 1 is a system diagram of the relay method of the above embodiment,
Station A and station B have the same configuration.

FIG. 2 is an internal block diagram of the switchboard.

Here, an example in which an operator of station A searches for ticket information of station B will be described.

In FIG. 1, in the switchboard 1 of office A, a key is first pressed to make a call according to the normal procedure, and this key information is transferred to the central processing unit 2. The central processing unit 2 that controls the switchboard uses this key information to connect the switchboard 1 and the digital switch 5 via the switchboard digital trunk 3.

The feature of Zero Hatsumeki is that in the above situation, when the operator of station A inputs a special number from the switchboard 1, the central processing unit 2 selects the outgoing route to station B based on this information. , the digital trunk 6 is captured and a call is made to the B station.When the B station receives the call from the digital trunk 61 and receives the above special number, the digital switch 5
1 via the digital trunk 61 and the central processing unit 21
The purpose is to simulate a pseudo switchboard 41 in which ticket information stored in the central processing unit 21 of the B station is received by the central processing unit 2 of the A station by key operation of the switchboard 1 of the A station at tIM. .

When this connection is completed, station B returns a response signal to station A.

When the A station receives a response signal from the digital trunk 6, the central processing unit 2 transfers this response signal to the exchange board.

In this embodiment, in FIG. 2 showing a block diagram of the internal structure of the switchboard, the switchboard 1 of the A station operates a relay in response to the response signal of the B station.

As a result, the communication lines that have been connected, that is, the headset 87, amplifier circuit 86, and digital/analog conversion circuit 85, are switched to the switchboard internal $lI control circuit 82, and the switchboard internal control circuit 82 is The bus is disconnected from the central processing unit 2 side. At the same time, the switchboard internal control circuit 82 displays on the display 84 that the connection has been completed. When the operator of station A confirms this display, he starts key operations on the keyboard 83 using the same procedure as when accessing the central processing unit 2 of his own station. When the switchboard internal control circuit 82 receives these key information from the keyboard 83, it sends out data via the switching circuit 81. This data is transferred to the pseudo exchange 41 via the exchange digital trunk 3, the digital switch 5, the digital trunk 6, the digital inter-office line 7, the B station digital trunk 61, and the digital switch 51.
will be forwarded to.

This pseudo exchange table 41 transfers information to the central processing bag W21 just like a membrane exchange table. The central processing unit 21 returns the ticket information corresponding to the key information to the pseudo switchboard 41 in the same operation as the processing for the general switchboard. Pseudo switchboard 4
1 goes through the opposite route to the one where the key information was received and goes to switchboard 1.
The data is transferred to the switchboard internal control circuit 82. The switchboard internal control circuit 82 displays information on the display 84 in accordance with the responded ticket information.

When the operator of station A finishes searching for the ticket information of station B in this way, he presses the search end key.

The switchboard internal control circuit 82 returns the switching circuit 81 to its original state using the search end key and transfers this ticket information to the central processing unit 2. When this is completed, the central processing unit 2 sends a call termination signal to the B station via the digital trunk 6, and the digital trunk 6 and the digital switch 5 are restored.

Further, the digital trunk 61 of the B station transfers the fact that the call termination signal has been received to the central processing unit 21. Central processing unit 21
11.1 causes the digital trunk 61, digital switch 51, and pseudo switchboard 41 to return to normal mode in response to this call termination signal.

When the operator of station B searches for tickets for station A,
You can do it in the opposite way to the above.

The above is an explanation of the operation of searching for a ticket for the switchboard of another station, and it is possible to write ticket information to another station using the same procedure.

In the explanation of this embodiment, an example was explained in which a digital exchange and a switchboard are directly connected by a digital circuit, but if a modem for data transfer is prepared inside the switchboard and the pseudo switchboard, the main The invention can also be implemented in an analog switch.

〔Effect of the invention〕

As explained above, according to the present invention, the central processing unit only adds software processing that is on the line of general call processing, such as connection processing using special numbers, and eliminates the hardware and software that should be added specifically for switchboard control. Since this is not necessary, tickets for other stations can be searched without any processing capacity problems, so there is real-time performance and the system's memory usage is reasonable. Furthermore, since the interoffice line is used for sending and receiving data, there is no need for a dedicated data line.
