When a to 3d are activated, the control units 34a to 34d start executing the business programs 60a to 60d. When the processing of the business programs 60a to 60d is started, the control units 34a to 34d stand by for the arrival of a message from the external connection line adapter 1. On the other hand, when the external line adapter 1 is activated, the control unit of the external connection line adapter 1 is
0 and the execution of API 51 are started. The control unit of the external connection line adapter 1 that has started the processing of the SCD 50 starts detecting the incoming call of the connected external analog line.

In this state, when there is an incoming call from the external analog line to the external connection line adapter 1, the control unit of the external connection line adapter 1 inputs the information sent from the line at the time of the incoming call. The information to be entered includes information indicating the service type of the line (that is, whether the other party of the call is anonymous, whether it is in the target area of the calling number notification service, and whether it is a public telephone). Information indicating whether or not) is included. Further, when the other party is in the area covered by the outgoing telephone number notification service and is not anonymous, information indicating the other party's telephone number is also included.

Next, the control unit of the external connection line adapter 1 follows the processing of the SCD 50 and extracts the information indicating the service type of the line and the information indicating the telephone number of the other party, which is input from the external analog line. Generate a calling phone number notification that includes. When the outgoing telephone number notification is generated, the control unit of the external connection line adapter 1 continues to use the API 51
In accordance with the processing of (1), a notification file including the contents of this calling telephone number notification is generated.

Specifically, first, the control unit of the external connection line adapter 1 newly creates a notification file "notification 1.TXT". Next, the control unit of the external connection line adapter 1 accesses the timer of the external connection line adapter 1 and acquires the current time. Then, the obtained time information is recorded in the first 14 bytes of the newly created notification file “notification 1.TXT”. Next, in the 15th byte, if the information indicating the service type of the line indicates that the other party of the call is anonymous, is in a non-target area of the outgoing telephone number notification service, or is a public telephone, Characters "P", "O" or "C" indicating that the service type of the line applies to these
To record. Then, when the notification of the outgoing telephone number includes the information of the telephone number of the other party, the telephone number of the other party is recorded in 20 bytes after the 16th byte. Since there is no information to be recorded after the area for storing the information of the other party's telephone number, no information is recorded after the 36th byte.

When the generation of the notification file "Notification1.TXT" is completed, the control unit of the external connection line adapter 1 determines the directory "\ NET \ KAISEN1" in the storage unit of the external connection line adapter.
The notification file "notification 1.TXT" is recorded in and the notification file is output to the modem 2. The notification file “notification 1.TXT” output to the modem 2 is transmitted to the computers 3a to 3d via the modems 2a to 2d.

Further, the control unit of the external connection line adapter 1 adds a record indicating the history of inputting the calling telephone number notification to the end of the log file. In the first 2 bytes of the record, the function code "3" for calling telephone number notification
1 "is recorded, and in the next 1 byte, the number of the line that received the call, that is," 1 "is recorded. In the subsequent 14 bytes, the external connection line adapter is set as the time when the outgoing telephone number notification was generated. The time last acquired by the control unit of 1 from the timer of the external connection line adapter 1 is recorded.The following 1 byte is left blank or the characters "P", "
Any of "O", "C", and "A" is recorded. When the other party's telephone number is included in the notification file "Notification 1.TXT", the telephone number is shown in the following 20 bytes. Information is recorded, and nothing is recorded in 57 bytes after the end of this 20-byte area.

Further, the notification file, the response file, the transfer file and the log file may be text files, and the data structure is not limited to the above.
Further, the types and data structures of electronic messages exchanged between the SCD 50 and the API 51 are not limited to those described above.

Further, the computers 3a to 3d may generate the response file in response to the state change between the on-hook / off-hook of the telephones 5a to 5d.
Alternatively, the telephones 5a to 5d may be provided with push buttons and the like, and the computers 3a to 3d may generate the transfer file in response to an operation of pushing the push buttons.

(Second Embodiment) In the originating telephone number notification system according to the present invention, the API 51 further generates a transmission table and a reception table for storing records of transmission and reception of a response file, and these Electronic messages may be exchanged with each of the computers 3a to 3d using each table. The calling telephone number notification system according to the second embodiment will be described below.

The physical configuration and logical configuration of this calling telephone number notification system are the same as those in the first embodiment. The API 51 generates a transmission table and a reception table in addition to the notification file and log file generated in the first embodiment.

The data structure of the transmission table and the reception table is, for example, as shown in FIG. As shown in the figure, the transmission table is composed of a plurality of records, and each record includes information for identifying each of the computers 3a to 3d,
The response file transmitted by each of the computers 3a to 3d is stored. The reception table is also composed of a plurality of records, and each record stores information for identifying each of the computers 3a to 3d and a response file received by each of the computers 3a to 3d.

When the upper command is input from the SCD 50, the API 51 does not return the electronic message of the upper command as it is and stores the content of the response file included in the upper command in the reception table according to the procedure described later. .

Next, the operation of the calling telephone number notification system will be described. The control unit 34 indicates that the response button is clicked in a state where each of the display units 32a to 32d is displaying that there is an incoming call and the calling telephone number.
Upon recognition by a to 34d, the control unit that recognizes the click of the response button among the control units 34a to 34d generates a response file "response 1.TXT".

The process by which the control units 34a to 34d generate the response file "response 1.TXT" and the data structure of the generated response file "response 1.TXT" are the same as those in the above-mentioned telephone response process. And the response file "Response 1.
The generation of TXT "is performed according to the processing of the business program 60a.

The control unit 34a sends a response file "response 1.TX
When T "is generated, the control unit 34a sends a response file" response "to the control unit of the external line adapter 1 via the modem 2a.

When the control section of the external connection line adapter 1 receives the response file "response 1.TXT", the control file is selected from the records of the reception table stored in the storage section of the external connection line adapter. It is stored in a record that includes information that identifies the computer 3a. And
The control unit of the external connection line adapter 1 waits for an incoming operation.

When the operation of the incoming call is detected, the control unit of the external connection line adapter 1 generates the electronic message of the incoming call notification according to the processing of the SCD 50. When you generate an incoming notification message,
The control unit of the external connection line adapter 1 continues to use the API 5
In accordance with the processing of No. 1, a telegram representing a higher-level command having the contents of the transmission table as the transfer target data is generated,
The process moves to 0.

The control unit of the external connection line adapter 1 is SC
In the process of D50, it is recognized that the electronic message generated in the process of API51 represents a higher-level command, the same electronic message as the electronic message is duplicated, and the process is returned to API51. When the processing returns to the API 51, the control unit of the external connection line adapter 1 inputs the duplicated electronic message of the upper command, and separates the transmission table portion from the electronic message.

Next, the control unit of the external connection line adapter 1 sequentially determines whether or not the response file is stored in each record of the separated transmission table, and the response file "response 1.TXT" is stored. And the computer indicated by the information contained in the record.
Then, the content of the response file “response 1.TXT” stored in the specified record is stored in the record in which the information indicating the computer other than the previously specified computer is stored in each record of the transmission table. .

When the response file is stored, the control unit of the external connection line adapter 1 controls the computers 3a to 3d.
Then, the reception table is sent back, the timer of the external connection line adapter 1 is accessed to obtain the information of the current time, and then a record indicating the history of the input of the upper command is added to the end of the log file. The contents and data structure of the added record are the same as in the first embodiment. However, 14 bytes after the 42nd byte from the beginning store 14 bytes from the 40th byte from the beginning of the response file "Response 1.TXT" stored in the transmission table.

When the addition of the record is completed, the control unit of the external connection line adapter 1 deletes the reception table stored in the storage unit of the external connection line adapter and shifts the processing to the SCD 50. The control unit of the external connection line adapter 1 is SCD5
When the processing is moved to 0, detection of disconnection of the first line is started.

On the other hand, each of the control units 34a to 34d of the computers 3a to 3d, which has received the reception table, searches the reception table and specifies the record having the information for specifying the computer including itself. That is, for example, the control unit 34a identifies a record in which information indicating the computer 3a is stored.

Next, each of the control units 34a to 34d determines whether or not the response file "response 1.TXT" is stored in the specified record. When it is determined that it is not stored (that is, it is the transmission source of the response file “response 1.TXT”), each of the control units 34a to 34d causes each display unit 32a to continue the current display. ~ 32d
Instruct. When it is determined that the information is stored (that is, the transmission source is not the transmission source of the response file "response 1.TXT"), the control units 34a to 34d cause the display units 32a to 32, respectively.
The d is instructed to stop displaying the incoming call and the calling telephone number is stopped to be displayed.

The display section of the computer other than the transmission source of the response file "response 1.TXT" stops the display indicating that there is an incoming call and the display of the outgoing telephone number, and the subsequent processing is the same as the reception described above. This is the same as the processing in the embodiment that does not use the table and the transmission table.

Further, for example, when the transfer button indicating the computer 3b is clicked after the computer 3a processes the telephone response and the user of the telephone 5a holds the first line, etc., the control unit 34a Recognizing the click of the transfer button, the transfer file "transfer 1.TXT" is generated according to the processing of the business program 60a. The content and data structure of the transfer file “transfer 1.TXT” are the same as those in the above-described embodiment that does not use the transmission table and the reception table.

The control unit 34a transfers the transfer file "transfer 1.TX.
When T "is generated, the control unit 34a transfers the transfer file" transfer to the control unit of the external line adapter 1 via the modem 2a.
1. Send TXT ”.

When the control section of the external connection line adapter 1 receives the transfer file "transfer1.TXT", the control file of the transfer table stored in the storage section of the external connection line adapter is transferred to the computer. 3a is stored in the record having the information. Then, the control unit of the external connection line adapter 1 generates a telegram representing a higher-order command whose contents of the transmission table are the data to be transferred, and S
Transfer processing to CD50.

The control unit of the external connection line adapter 1 is SC
In the process of D50, it is recognized that the electronic message generated in the process of API51 represents a higher-level command, the same electronic message as the electronic message is duplicated, and the process is returned to API51. When the processing returns to the API 51, the control unit of the external connection line adapter 1 inputs the duplicated electronic message of the upper command, and separates the transmission table portion from the electronic message.

Next, the control unit of the external connection line adapter 1 sequentially determines whether or not the transfer file is stored in each record of the separated transmission table, and the transfer file "transfer 1.TXT" is stored. Identify the record Then, the contents of the transfer file “transfer 1.TXT” stored in the specified record are analyzed to determine the transfer destination computer (that is, the computer 3b). When the computer 3b that is the transfer destination is determined, the control unit of the external connection line adapter 1 transfers the transfer file to the record having the information including the information indicating the computer 3b that is the transfer destination among the records in the reception table. Transfer 1.TXT ”
To store.

After the transfer file is stored, the control unit of the external connection line adapter 1 is controlled by the computers 3a to 3d.
Then, the reception table is sent back, the timer of the external connection line adapter 1 is accessed to obtain the information of the current time, and then a record indicating the history of the input of the upper command is added to the end of the log file. The contents and data structure of the added record are the same as in the first embodiment. However, 14 bytes after the 42nd byte from the beginning store the contents of the 14th byte from the 40th byte from the beginning of the transfer file "transfer 1.TXT" stored in the transmission table.

When the addition of the record is completed, the control unit of the external connection line adapter 1 deletes the reception table stored in the storage unit of the external connection line adapter and shifts the processing to the SCD 50. The control unit of the external connection line adapter 1 is SCD5
When the processing is moved to 0, detection of disconnection of the first line is started.

On the other hand, each of the control units 34a to 34d of the computers 3a to 3d, which has received the reception table, searches the reception table and specifies the record having the information for specifying the computer including itself. That is, for example, the control unit 34a identifies a record in which information indicating the computer 3a is stored.

Next, each of the control units 34a to 34d determines whether or not the transfer file "transfer 1.TXT" is stored in the specified record. When it is determined that the data is not stored (that is, it is not the transfer destination), each control unit 3
4a to 34d instruct each of the display units 32a to 32d to continue the stop of the display. When it is determined that it is stored (that is, the transfer destination is itself), the control unit 34
a to 34d instruct the display units 32a to 32d to display that the call has been transferred, and also to display the calling telephone number.

The display unit 32b of the transfer destination computer (that is, the computer 3b) starts displaying the transfer of the telephone and displaying the calling telephone number. And the processing is the same as the processing in the embodiment that does not use the transmission table.

Although the embodiments of the present invention have been described above, in each of the above embodiments, the notification file, the response file, and the transfer file are in the text format.
There is no need to convert information by a modem or a protocol that depends on the configuration of the communication control program. As a result,
SCD50, API51, business programs 60a-60
It is easy to generate and change d and the like. Therefore, it is desirable that the information exchanged between the other external connection line adapter 1 and the computers 3a to 3d be in text format. However, for example, a binary format, a format including analog information such as voice, or the like may be used.

In the above description, the telephone line includes both a wired line and a wireless line, a normal analog line and a digital line such as ISDN, and may be a private line or a public line, or a voice line. And any data line. That is, the present invention can be applied to various situations that require a communication response.

The calling telephone number notification system of the present invention can be realized by using a normal computer system instead of a dedicated system. For example, a medium (floppy disk, CD-ROM, etc.) in which a program for executing the above-described operation is stored in a personal computer.
By installing the program from, it is possible to configure a calling telephone number notification system that executes the above-described processing.

The medium for supplying the program to the computer may be a communication medium (a medium that temporarily and fluidly holds the program, such as a communication line, a communication network, a communication system). For example, the program may be posted on a bulletin board (BBS) of a communication network and distributed via the network. Then, the above process can be executed by activating this program and executing it under the control of the OS in the same manner as other application programs.
