The operation of the PBX / computer interlocking system thus configured will be described with reference to FIG. FIG. 2 is a flowchart showing the operation of the PBX / computer interlocking system of FIG. Here,
For the sake of simplicity, the following is assumed (premises 1 to 5).

As a first premise, the CTI server 2 is notified in advance of the addresses of all the PCs in the own network 6. For example, Microsoft's Windows 95, which is widely used as a PC OS in recent years, uses TCP / IP as a protocol, and periodically broadcasts the address of its own PC to each other. PC (host) I
The P address is stored. Thus, it is assumed that the IP address of another PC in the own network 6 is registered in the PC address storage unit 22 in the CTI server 2 in advance.

As a premise 2, the CTI server 2 has a PBX 1
When connecting to the PBX, dedicated software for communicating with the PBX 1 is introduced, and necessary settings are made. At this time,
The space of the extension number of the connected PBX 1 is also set. For example, in the present embodiment, the space of the extension number of the connected PBX 1 is from 101 to 699. Accordingly, it is assumed that the extension number of the PBX 1 connected in advance is registered in the extension number storage unit 23.

As a premise 3, the CTI server 2 has a PBX 1
Can be requested to generate a ringer signal that is not used during normal operation. The ringer signal is a signal of 20 Hz, and has a specification in which a signal continuation period (ringing period) and a stop period are periodically repeated. For example, in Japan, the ringing period is 2 seconds, and the pause period is 1 second. In the present embodiment, a ringer signal (20
Hz) repeats a pattern of a ringing period of 0.5 seconds and a pause period of 0.5 seconds, and such a signal pattern is not used in normal operation. Further, the network connection / disconnection control signal receiving unit 51 in the pair detection concentrator 5 receives the signal of the pattern (predetermined signal), turns off the network connection / disconnection switch, and receives the predetermined signal. If not, the switch is connected.

As a premise 4, in the present embodiment, it is assumed that an Ethernet network is used as the network 6, and TCP / IP is used as a communication protocol. Therefore, the PC on the network 6
The following description will be made on the assumption that the address of “.

As premise 5, in the present embodiment, a certain I
A command called PING is used to check whether communication with a PC having a P address is possible. Ping is often used over TCP / IP protocols. When a ping is issued for a certain address, the PC having that address immediately returns a response if the ping is received. As a result, if there is no response after waiting for a certain time or more, it is understood that the PC having the address is not connected to the network 6.

Next, the operation of the PBX / computer interlocking system of FIG. 1 will be described with reference to FIG.

In FIG. 2, first, the control section 28 refers to the extension number storage section 23 and extracts the extension number at the head (S1). Here, it is assumed that the extension number 101 has been extracted. Next, the control unit 28 refers to the PC address storage unit 22 and extracts the network address of the leading PC (S2). Here, the description will be made assuming that the IP address 179.23.13.1 is extracted as the address. Next, the control unit 28 issues an instruction to “output a network disconnection request” to the CTI request transmission unit 21 for the extension number currently extracted (S3). Here, since a “network disconnection request” is instructed for the 101st extension number,
The I request sending unit 21 outputs a “network disconnection request” via the CTI link 7, and the CTI request receiving unit 11 receives this. Then, the CTI request receiving unit 11 outputs a signal for “disconnecting the network” to the telephone line corresponding to the extension number 101 so as to output a signal for disconnecting the network.
An instruction is given to the disconnection control signal generator 12a. The network connection / disconnection control signal generator 12a outputs a ringer signal (20) that repeats a pattern of a ringing period of 0.5 seconds and a pause period of 0.5 seconds.
Hz). The network connection / disconnection control signal receiving unit 51a detects the ringer signal and instructs the network connection / disconnection switch 52 to disconnect the network. Then, the network connection / disconnection switch 52a corresponding to extension number 101 is disconnected.

Next, the control unit 28 sends “1” to the currently extracted IP address 179.23.13.1.
In order to check “whether or not communication with a PC of 79.23.13.1 is possible,” the determination packet transmitting unit 25 is instructed to execute ping (PING) (S4). Then, the determination packet transmitting unit 25 outputs 179.23.1.
3. Ping the IP address of 3.1.

Next, the response packet receiving unit 26 informs the control unit 28 of the result of the ping executed in step 4.
If there is a response, the process proceeds to step 10 (S5). If there is no response, the process proceeds to step 6 (S
5). Here, the description is continued assuming that there is no response. Since the network connection / disconnection switch 52 of the pair detection concentrator 5 connected to the extension 101 in steps 3 and 4 is in the disconnected state, there is no response. Address 17
The PC having 9.23.13.1 is connected by the pair detection concentrator 5, that is, the extension telephone of extension 101 and the PC having the IP address 179.23.13.1 are a pair. You can see that.

Next, the control unit 28 receives the notification that there is no response from the response packet receiving unit 26, and communicates with the extension telephone having the extension number 101 and the IP address 179.23.1.
It is determined that the PC having 3.1 is a pair, and the extension-PC
The extension number 101 and the I
The P address 179.23.13.1 is stored in association with the P address (S6). Next, the control unit 28 outputs a network connection request to the CTI request sending unit 21. Then, the CTI request sending unit 21 sends the PB
It instructs X1 to stop the network disconnection signal for extension number 101 (S7). Then, PBX1
Then, the CTI request receiving unit 11 receives an instruction to stop the network disconnection signal, and instructs the network connection / disconnection signal control unit 12a to output a ringer signal (a ring pattern of 0.5 seconds and a pause of 0.5 seconds). 20 Hz). Then, the network connection / disconnection signal control unit 12a stops outputting the signal which has been repeatedly generated for the extension number 101 up to now. Then, since the network connection / disconnection control signal receiving unit 51a does not detect the signal, it issues an instruction to the network connection / disconnection switch 52a to enter the connection state. As a result, the network connection / disconnection switch 52a sets the network in a connected state. Next, the control unit 28 refers to the extension number storage unit 23, and determines whether or not the extension number to be checked for the correspondence is still left (S20).
8). If there are, go to step 9. If there are no remaining PCs, the PCs corresponding to all extensions
Since the address has been checked, the process ends. Here, the description is continued assuming that the extension number to be checked still remains.

Next, at step 9, the control unit 28 extracts the extension number to be examined next and proceeds to step 2.
Here, the description is continued assuming that the extension number 102 has been extracted. Thereafter, step 2 is also performed for extension number 102.
The same processing as in steps # 5 to # 5 is performed. Next, a process performed when a response is received in step 5 will be described. In this case, extension 10
Despite the network disconnection for 2nd, 1
Since the PC having the address of 79.23.13.1 responded, the P paired with the extension telephone at extension 102 is set.
It can be seen that C is not the PC having the address. Therefore, the process proceeds to step 10 to retrieve the next address candidate.

Next, the control unit 28 refers to the PC address storage unit 22, and determines whether or not ping has been performed for all IP addresses (S10). If the execution has not been completed for all, the process proceeds to step 11.
If the execution has been completed for all, the process proceeds to step 12. Here, it is assumed that ping has not yet been performed for all IP addresses. Next, the control unit 28 refers to the PC address storage unit 22 to fetch the next address to be pinged (S11), and proceeds to step 4. Here, 179.23.13.2 is extracted and P with the address of 179.23.13.2 is obtained.
The description is continued assuming that the extension number of the extension telephone paired with C is 102. This time, 179.2
Steps 4 to 7 are executed for the address of 3.13.2.

As described above, the IP address of the PC corresponding to each extension number is sequentially determined, and the extension-PC address correspondence table storage unit 24 is filled.

Next, a case in which ping has been performed for all IP addresses in step 10 will be described. It is assumed here that the extension number of interest is 103. In this case, the process proceeds to step 12. In step 12, since it is known that there is no PC paired with the extension telephone having the extension number 103, the fact is written in the extension-PC address correspondence table storage unit 24.

As described above, it is determined whether there are PCs corresponding to all extension numbers, and if there is a corresponding PC, its IP address is written in the extension-PC address correspondence table storage unit 24. I will go.

FIG. 3 is a table showing the contents of the completed extension-PC address correspondence table storage unit 24.

In the present embodiment, ping is executed for all IP addresses while paying attention to a certain extension number, and the correspondence relationship is determined. A method of deciding the corresponding party while repeatedly connecting / disconnecting the network to the extension number is also conceivable. In the present embodiment, a certain extension telephone and the network connected to the line are temporarily disconnected,
Ping was performed in this state, and the method of specifying the PC that did not respond as the corresponding PC was shown. Contrary to this method, all the extension telephones and the connected network were once temporarily disconnected, It is also conceivable to set a connection state one by one and check the PCs that respond by ping.

As described above, according to the present embodiment, PB
