Referring to FIG. 4, monitor connection control unit 12
Receives the call monitor instruction from the monitor instruction telephone 40 and instructs the call path switch 11 to connect the input trunk 15a of the trunk number 100 and the output trunk 16a of the trunk number 200 to the three-way call trunk 13. . In response to this command, the communication path switch 11 connects the input trunk 15a and the output trunk 16a to the three-way communication trunk 13. Thereby, the call monitor telephone 30
Can monitor the voice of the specified trunk line.

Referring to FIG. 5, monitor indicating telephone 40 is shown.
Dials the trunk number 100 and the trunk number 200 for an instruction to suspend the call monitor, then dials the three-way call trunk number 300, and dials a disconnect command indicating an instruction to disconnect. Here, the disconnection command is a predetermined command that instructs the monitor connection control unit 12 to control disconnection of the communication path switch 11. The monitor connection control unit 12
When an instruction to suspend the call monitor is received, a command is issued to the call path switch 11 to disconnect the input trunk 15a of the trunk number 100, the output trunk 16a of the trunk number 200, and the three-way call trunk 13. In response to this command, the communication path switch 11 sets the input trunk 15a.
And the output trunk 16a are disconnected from the three-way call trunk 13.

Referring to FIG. 6, in order to monitor the call on another trunk line from the state of the call monitor suspension shown in FIG. 5, monitor indicating telephone 40 transmits another input trunk and output trunk as a re-monitor instruction. The trunk number, here the trunk number 101 of the input trunk 15b and the trunk number 201 of the output trunk 16b, are dialed, and the connection command is dialed. Monitor connection controller 12
Receives the re-monitoring instruction from the monitor instruction telephone 40 and instructs the communication path switch 11 to connect the input trunk 15b of the trunk number 101 and the output trunk 16b of the trunk number 201 to the three-way telephone trunk 13.
In response to this command, the communication path switch 11 connects the input trunk 15b and the output trunk 16b to the three-party communication trunk 1
Connect to 3. As a result, the call monitor telephone 30 can monitor the call voice of another trunk line.

Referring to FIG. 7, when terminating the call monitor, the monitor instruction telephone 40 and the call monitor telephone 30 are disconnected.

Next, the operation for monitoring a call on the subscriber line will be described in detail with reference to FIGS.

Referring to FIG. 8, call monitor telephone 30
Is the monitor service code and the three-way call trunk number 30
Dial 0.

The monitor connection control unit 12 of the exchange 10 receives the monitor service code and the three-party call trunk number 300 from the call monitor telephone 30 and recognizes that the request is a call monitor request, and recognizes the request for a call monitor. The call monitor telephone 30 which captures the three-party call trunk 13
Command to the communication path switch 11 to connect with the communication path switch. In response to this command, the call path switch 11 connects the call monitor telephone 30 and the three-way call trunk 13.

Referring to FIG. 9, next, monitor indicating telephone 40 dials the monitor service code in order to instruct a call monitor, and then the subscriber telephone number of the telephone to monitor the call, here, , Telephone 20a
The subscriber number 400 of the input trunk 15a is dialed and the trunk number 100 of the input trunk 15a is further dialed.
The user dials the call trunk number 300, and finally dials the connection command.

Referring to FIG. 10, monitor connection control unit 12
Receives the call monitor instruction from the monitor instruction telephone 40, and connects the telephone 20a and the input trunk 15a to each other.
Switch 11 so that it connects to call trunk 13
Command. Upon receiving this command, the communication path switch 11 connects the telephone 20a and the input trunk 15a to the three-way communication trunk 13. As a result, the voice of the designated telephone 20a can be monitored from the telephone monitor telephone 30.

Referring to FIG. 11, monitor indicating telephone 40
Dials the subscriber telephone number 400 and the trunk number 100 for an indication to suspend the call monitor, then dials the three-way call trunk number 300 and dials the disconnect command. Monitor connection control unit 1
When receiving an instruction to suspend the call monitor, the telephone 2a of the subscriber telephone number 400 and the trunk number 1
Instruct the communication path switch 11 to disconnect the input trunk 15a of 00 and the three-way communication trunk 13. The communication path switch 11 receives this command, and
0a and the input trunk 15a are disconnected from the three-way call trunk 13.

Referring to FIG. 12, in order to monitor the call of another call telephone from the state of the call monitor suspension shown in FIG. 11, monitor monitor telephone 40 transmits a subscriber telephone of another telephone as a re-monitor instruction. A connection command is dialed with a number, here, the subscriber telephone number 401 of the telephone 20b. The monitor connection control unit 12 receives the re-monitoring instruction from the monitor instruction telephone 40, and
Is instructed to connect to the three-way communication trunk 13. In response to this command, the communication path switch 11 connects the telephone 20b to the three-way communication trunk 13. As a result, it is possible to monitor the call voice of another call telephone 20b from the call monitor telephone 30.

Referring to FIG. 13, when ending the call monitor, monitor instruction telephone 40 and call monitor telephone 30
And disconnect.

The call monitoring of the trunk line can be monitored from the state of the call monitor temporary stop of the call telephone shown in FIG. For this reason, in FIG. 12, the monitor instruction telephone 40 can monitor the call of the corresponding trunk line by designating the trunk number instead of the subscriber telephone number of the telephone telephone of the re-monitor instruction.

Further, it is possible to monitor the telephone call of the telephone from the state of the temporary stop of the telephone call monitor shown in FIG. Therefore, in FIG. 6, the monitor instruction telephone 40 can monitor the call of the corresponding telephone by designating the subscriber telephone number of the telephone in place of the trunk number of the re-monitoring instruction.

Referring to FIG. 14, an exchange according to a second embodiment of the present invention is the first embodiment of the present invention except that monitor connection control unit 12 has password recognition unit 12a. Same as a switch. Therefore, only the description related to the password recognition unit 12a will be given. The password recognizing unit 12a stores a predetermined password, and accepts a call monitor instruction when the password coincides with a password from the monitor instruction telephone 40 or the telephone call monitor telephone 30. Thereby, the call monitor can be restricted, and the confidentiality of the call monitor can be ensured.

[0037]

As described above, since a telephone call is monitored only on a telephone line, a dedicated terminal is not required when conducting a test call monitor, and there is no restriction on the equipment of the dedicated terminal, so that a large number of tests can be performed at one time. Become.

Further, according to the present invention, since the telephone call on the line is monitored by only two telephones, there is no need to set up a dedicated terminal, so that there is no restriction on the place and the tester need only prepare the telephone. When you want to conduct a test, you can monitor the call test from anywhere.
