FIG. 1 is a block diagram showing an embodiment of a telephone charge management device in a private branch exchange of the present invention. In the figure, a terminal 3 is connected to an exchange circuit 1 via an extension circuit 2, a station line 5 is connected via a subscriber circuit 4, and a connection line 7 (for example, a dedicated line) is connected via a dedicated line circuit 6. Or a private line) is connected. Further, the extension circuit 2, the subscriber circuit 4, and the leased line circuit 6 are connected to the control unit 8, and the storage unit 9, the call charge management unit 10 and the maintenance terminal 11 are also connected.

FIG. 2 shows an outline of a first private branch exchange 21 and a second private branch exchange 22 which are constructed similarly to the private branch exchange shown in FIG. Connected through. Now, by dialing the terminal 3 in the first private branch exchange 21, for example, a 4-digit relay number aaaa for relaying the second private branch exchange 22 and the second private branch exchange 22 with the central line 5 When the special number b indicating the use of the telephone number and the other party's number xx ... x are sequentially instructed, the control unit 8 in the first private branch exchange 21 is dedicated to the extension circuit 2 and the dedicated extension circuit 2 in accordance with the relay number. The line circuit 6 is connected via the exchange circuit 1, and a selection signal indicating the special number and the partner's number is sent to the connection line 7 via the dedicated line circuit 6. When the control unit 8 in the second private branch exchange 22 inputs this selection signal through the leased line circuit 6, the leased line circuit 6 and the subscriber circuit 4 are connected via the exchange circuit 1 in accordance with the special number. At the same time, a selection signal indicating the other party's number is sent to the central line 5 via the subscriber circuit 4. Therefore, the call is transmitted to the central office line 5 from the first private branch exchange 21 through the second private branch exchange 22.
At the time of this call, the control unit 8 in the first private branch exchange 21 performs the processing shown in the flowchart of FIG. 3, and the terminal 3 is charged as a local line.

First, the control unit 8 in the first private branch exchange 21 determines which of the extension, the office line 5 and the connection line 7 has been called (step 40). When the call is made to the station line 5, the call charge management unit 10 calculates the call charge and the calculation result is stored in the storage unit 9 (step 50). Then, since the call is to the connection line 7 here, the terminal 3
The above-mentioned number aaaabxx ... x consisting of the relay number, the special number, and the other party's number dialed at is stored in the storage unit 9 (step 41).

Next, since the number of digits of the relay number for relaying another private branch exchange is preset to, for example, 2 digits or 4 digits, the control unit 8 stores the table in the storage unit 9 as shown in FIG. 2 out of 2 and 4 indicating the number of digits of the relay number stored in A in advance is read (step 42), and the above-mentioned connection is projected from the head of the number aaaabxx ... x read from the storage unit 9. The digits are deleted and the number aabxx ... x is reconstructed (step 43). After that, the control unit 8 reads the special number b indicating the transmission to the office line which is stored in advance in the table B of the storage unit 9 as shown in FIG. 4 (step 44), and is reconfigured with this special number b. The first number a of the numbers aabxx ... x is compared to determine whether they match (step 45). Here, since the numbers a and b of both do not match, the control unit 8 returns to the processing of step 42,
4 indicating the number of digits of the relay number is read from the table A shown in FIG. Further, the number aaaabxx ... x stored in the storage unit 9 is read out, four digits are deleted from the head of this number, and the number bxx ... x is reconstructed (step 43). Thereafter, the control unit 8 reads out the special number b from the table B shown in FIG. 4 of the storage unit 9 (step 44), and stores this special number b and the first number b of the reconfigured numbers bxx ... x. By comparison, it is determined that both numbers b and b match (step 45). If such a match is found, the other party's number is, for example, 4 digits or more and 10 digits or less.
... Determines whether x is 4 digits or more and 10 digits or less.
Here, when the control unit 8 determines that the number xx ... x is between 4 digits and 10 digits, the call charge management unit 10 calculates the call charge corresponding to the number xx ... x, and The calculation result is stored in the storage unit 9 as related to the terminal 3 (step 50). Further, the control unit 8 has a number xx ... x with four digits or more 10
If it is determined that the number is not within the digits, or if the number reconstructed by deleting the four digits from the beginning of the number stored in the storage unit 9 at the time of calling does not match the special number, Instead, this number is deleted from the beginning by four digits and the reconstructed number is stored in the storage unit 9, and the processing from step 41 described above is repeated until there are no numbers stored in the storage unit 9. This is the second private branch exchange 22
A relay number for relaying the second private branch exchange 22 when not only relaying another private branch exchange.
Subsequent to aaaa, a relay number (for example, a two-digit or four-digit number) for relaying another private branch exchange is dialed on the terminal device 3. Therefore, these relay numbers can be deleted to determine the special number. is there.

Thus, according to this embodiment, the first private branch exchange 21
When the call is made to the central office line 5 through the second private branch telephone exchange 22 from, the first private telephone exchange 21 is charged as a central office line.

It should be noted that the present invention is not limited to the case where a plurality of private branch telephone exchanges are installed in a unit charge area, and even when each private branch telephone exchange is installed in a different charge area, a clear charge system for relaying is provided. If predetermined, the call charge can be accurately managed based on the relay number and the other party's number.

[Effects of the Invention] As described above, according to the telephone charge management device in the private branch exchange of the present invention, when the call is made to the central office line by relaying to another private branch telephone exchange, it is treated as the central office line. Since the charges can be made, it is possible to accurately manage the call charges related to the transmission of the office line to the terminals of one private branch exchange.
