Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a communication system between a data processing device and an exchange,
Specifically, the present invention relates to a transmission/reception method for control signals such as connection/disconnection of communication lines.

[Prior Art] Conventionally, a subscriber line signaling system or a line individual signaling system has been used for communication between a data processing device and an exchange. On the other hand, in addition to the individual line signaling system, a common line signaling system is generally used for transmitting and receiving signals between exchanges. In the individual line signaling system, control signals etc. are transferred using an information line for data transmission and reception, but in the common line signaling system, control signals etc. are transferred using a signal line (common line) that is separate from the information line. . For this reason, the J (line signaling system) has advantages such as being able to transfer control signals using a common line while transmitting and receiving data on an information line, and being able to define a wide variety of signals that are not available in individual line signals. When applying the common channel signaling method, which has these advantages, to communication between data processing equipment and switching equipment, major hardware and software modifications are required because the data processing equipment does not support the common channel signaling method. It was said that

FIG. 4 shows a conventional system configuration using a line-individual signaling system, where 1 is a data terminal, 2 is an exchange, 3 is a data processing device, and 4 is an information line. FIG. 5 shows the communication example shown in FIG. 4, and is a sequence when a call is made from the data terminal 1 to the data processing device 3. When the data terminal 1 sends a dial pulse and receives an exchange @2, the exchange 2 sends a ringing tone to the data processing device 3. For this calling agency, the information line control unit 1.0 in the data processing bag @3
detects a call and changes the state of the information line 4 to data transmission/reception, and then the transmission and reception of information between the data terminal I and the application computer block 9 is started. With this configuration, control signals cannot be transmitted and received between the data processing device 3 and the exchange 2 during data communication.

[Purpose of the invention]

The present invention enables communication using the common channel signaling method without making changes to the information line control unit or application program of the data processing device by adding an adapter device to the data processing device that uses the individual line signaling method. It is in.

〔Example〕

FIG. 1 shows a system configuration of an embodiment of the present invention. 1st
In the figure, a data terminal 1 and an exchange 2 are connected through an information line 4, and an exchange 2 and a data processing device 3 are connected through an information line 4 and a common signal line 5.

The data processing device 3 has a matching device 6, a common line signal line control unit 7, a matching unit 8, an application program 9, an information line, and a control unit 10, and the common line signal line 5 is connected to the common line signal line control unit 7. , the information line 4 is connected to an information line control section 10 via a matching device 6. The information line control section lo is the same as the information line control section in FIG. 4, and can control line individual signals. The matching device 6 is also connected to the matching section 8, and can receive signals from the common signal line control section 7 via the matching section 8.

The matching device 6 transfers this signal to the information line control section 10, so that the information line control section 10 can treat the common signal line as if it were an individual signal line.

The operation shown in FIG. 1 will be explained below based on the communication examples shown in FIGS. 2 and 3. FIG. 2 shows a sequence when a data terminal makes a call, and FIG. 3 shows a sequence when a data processing device makes a call. In addition, in FIGS. 2 and 3, broken line arrows mean signals related to the common line signal line.

Data terminal calling sequence: When the data terminal 1 sends a dial pulse and the exchange 2 receives it, the exchange 2 sends a connection request signal to the data processing device 3 through the common signal line 5. In the data processing device 3, when a connection request signal is sent through the common signal line 5, a calling request is sent to the matching unit 8 via the common signal line control unit 7. Based on this, the matching section 8 instructs the matching device 6 to send a ringing tone to the information line control section 10 (ringing tone pseudo instruction). When notified of the ringing tone, the information line control unit 10 shifts the information line 4 to a state in which data can be transmitted and received, in the same way as when it is notified by the line individual signal. Thereafter, a call notification is sent from the information line control section 10 to the matching section 8 and further to the application program 9. After the calling process is completed, communication between the data terminal and the application program 9 becomes possible.

Data processing device calling sequence: A calling request is made from the application program 9 to the matching unit 8.
, the matching section 8 instructs the common line signal line control section 7 to issue a call request. The common line signal line control section 7 sends a connection request signal to the exchange 2 using the common line signal line 5.

As a result, the exchange 2 returns a response signal to the coplanar signal line control unit 7 using the common line signal line 5, and the common line signal line control unit 7 notifies the matching unit 8 of this. Thereafter, the matching unit 8 queues up to the information line control unit 10 and requests connection using the same method as the line individual signaling system.

In response to this, the information line control unit 10 sends a calling signal and a dial number to the information line 4 as individual line signals. Since it is not necessary to send a pulse, the matching device 6 suppresses the sending, and the information line control unit 10/\ notifies that the sending of the calling signal and the dial pulse has been completed normally (dial pulse sending pseudo ).After that, the information line control unit 10 sends the data transmission book to the information line 1, and sends the response to the matching device 6 information port j1!2 control unit 1
0 is sent to the matching unit 8, and the matching unit 8 passes the calling 'i°C completion 3 to the application UJgram 9 (11). As shown in step 2, communication between application block 9 and data terminal 1 becomes possible.

In this way, the conventional data processing device includes a matching device 6, a common line signal line control unit 7. By adding the matching section 8, the information line control section 10. Application program 9
It becomes possible to communicate using the common line signaling method without making any changes to the system.

Note that the above-mentioned processing of the common line signal line control unit 7, matching unit 8, and information line control unit 10 can be easily achieved by, for example, applying a control method using a program (communication control program, matching program). be.

〔Effect of the invention〕

As explained above, according to the present invention, by adding an adapter to a data processing device using a line individual signaling system,
By absorbing the difference between the information line control method of the individual line signaling system and the common line signaling system, the common line signal line can be applied while using the information line control method of the conventional data processing equipment. It has the advantage that the processing device and the exchange can be directly connected through the common line signal line, and that control signals and the like can be sent and received through the common line signal line even when data is being sent and received over the information line.
