The office line trunk 40 and the three-way conference trunk 41 accommodated in the time division switch 30, the central processing unit 31 that controls all sequence control in the private branch exchange, and the central processing unit 31 through the input / output interfaces 50 and 51, respectively. The charging device 60 and the maintenance terminal 70 are connected, and the storage device 32 is connected to the central processing unit 31.
The office line trunk 40 is connected to a public line network 80.

The three-party conference trunk 41 is a time division switch 3
It is a generally known three-party conference trunk connected to 0 ingress port and 0 egress port. In the present embodiment, a two-way call between the calling extension terminal 10 and the office line trunk 40 is a supervisor extension. Used by the terminal 11 to monitor.

The billing device 60 uses the detailed billing data for each extension terminal at the time of originating a station line (extension number of the originating extension terminal, the station extension number dialed by the originating extension terminal at the time of originating the station line, the call start time and the call end time, etc.). ) Is the input / output interface 50
It is a general billing device recorded through.

In the storage device 32, a maintenance person charges the billing device 60.
The detailed billing data for a predetermined period (for example, one month) read out from the above is checked, and one that is considered to be a private station line outgoing call is selected from this and this station line outgoing number data is input / output interface 51, central processing unit 31. Through maintenance terminal 7

And are stored.

Next, the operation of this embodiment will be described with reference to FIGS.
And it demonstrates with reference to FIG.

First, the maintenance person checks the detailed billing data read out from the billing device 60 for a predetermined period, and the number of digits of the station-line calling number data of the call to be monitored because there is a suspicion of a private station-line outgoing call. When the number data of each digit and the extension number of the supervisor extension terminal 11 used by the supervisor for monitoring are input from the maintenance terminal 70, these data are sent to the central processing unit 31 through the input / output interface 51.

The central processing unit 31 stores this data in an empty memory area (here, memory area # 1) in the table of the storage unit 32. Therefore, in the memory area # 1, the digit number data DGT1 of the station line transmission number data input by the maintenance person from the maintenance terminal 70, the number data a1, ..., Q1 of each digit, and the central processing unit 31 are input. The accommodation position data LEN1 on the time divisional switch 30 converted from the extension number of the supervisor extension terminal 11 is stored.

In this state, the extension subscriber sends the originating extension terminal 1
When dialing the station line transmission from 0, this station line transmission number (so-called 0 transmission number) is stored in a register (not shown) through the line circuit 20 and the time division switch 30 as is generally known. (Step S301).

Next, the central processing unit 31 receives this station line transmission number from the register and clears the memory area number counter in the table of the storage unit 32 (S302), and the digit indicated by the digit number data DGT1 of the memory area # 1. The number data of each digit up to the number (9 digits) is compared with the station line transmission number from the register (S303).

As a result of this comparison, if they do not match (S30
No in 4), the count value of the memory area number is incremented by 1 (S305), and if the count value is not ≧ n (NO in S306), the process returns to S303 until each memory area # 2 reaches the memory area #n. Repeat digit number comparison.

If there is no match even if the count value reaches n (YES in S306), a generally known station line originating connection is performed.

That is, the transmitting extension terminal 10 has the line circuit 2
0, call path 100 of the set time division switch 30
(Dashed line shown), public line network 8 through the trunk 40
You can talk with 0 recipients.

When the extension subscriber dials the 9-digit station line originating number "043256789" from the originating extension terminal 10, this station line originating number coincides with the station line originating number data in the memory area # 1. (YES in S304),
The central processing unit 31 sets the monitor path (S30).
8).

That is, the central processing unit 31 is the public line network 8
After sending the dial signal to the 0 side, the accommodation position data LEN1 in the memory area # 1 is read from the storage device 32, and the monitor path 103 (illustrated by the solid line) in the time division switch 30 is closed based on this, in general. A call signal is sent to the supervisor extension terminal 11 through the line circuit 21 by a known method.

When the supervisor responds, the central processing unit 31 sets the call path 101 and the call path 102 (shown by solid lines) in the time division switch 30.

As a result, the transmitting extension terminal 10 can communicate with the called party through the line circuit 20, the communication path 101, the three-party conference trunk 41, the communication path 102, the office line trunk 40 and the public line network 80, and at the same time supervising. The person can monitor the above-mentioned call by the supervisor extension terminal 11 through the three-way conference trunk 41, the monitor path 103 and the line circuit 21.

In this embodiment, all digits of the office line calling number are compared, but if a private station line outgoing call to a specific outbound area is monitored, the digits up to the area code will be compared. The monitor path may be set when the both match only by comparing the number data.

Further, although one supervisor extension terminal is shown in this embodiment, a plurality of supervisor extension terminals are provided and the accommodation position data on each time division switch 30 is registered in the table of the storage device 32. You may.

As described above, according to this embodiment, the supervisor can automatically monitor the local line outgoing call from the outgoing extension terminal. Therefore, when the call is a private local line outgoing call, , It is possible to take precautions against private station line calls, such as alerting the caller after the end of the call or charging the call charge.

[0033]

As described above, according to the present invention, from the detailed billing data of the predetermined period read by the maintenance person from the billing device, the supervisory line number data of the station line outgoing call to be monitored is displayed. This is selected and input from the maintenance terminal and stored, and the calling number data dialed by the caller from the extension terminal to compare with the calling line data read from the storage means are compared. Preventing when the monitored call is a private local line outgoing call by calling the supervisor extension terminal when the comparison result matches and monitoring the call through the three-way conference trunk when the supervisor answers It has the effect that it can be constructed.
