Each is connected to the speech path switch 12 via the outside line interface 11 (11 _{1 to} 11 _n ). On the other hand, the communication path switch 12 and the lines 3 ₁ to 3 from the respective slaves 4 ₁ to 4 _m
m is the telephone interface 13 (13 ₁ to 1)
3 _m ), and the switching connection is made by the cross point of the analog switch or the relay contact in the speech path switch 12. The outside line interfaces 11 _{1 to} 11 _n have functions of detecting an incoming call, forming a DC loop for an outside line, holding and dialing with a pulse signal or a composite voice frequency signal, and the communication path switch 12 has outside lines 2 ₁ to 2 _{n. n} and the slaves 4 ₁ to 4 _m, and further has a switching connection function between the slaves 4 ₁ to 4 _m . In addition, telephone interfaces 13 _{1 to} 13
_{The m} supplies the call power supply to the slave units 4 ₁ to 4 _m via the call line 32 and transmits / receives the data signal and supplies the control power supply via the signal line 33.

These controls are performed by the well-known processor unit (CPU) 14 and fixed memory (ROM) 1 in the main device 1.
5 and the variable memory (RAM) 16 in the control unit, the program in the ROM 15 as described later, C
This is performed by the PU 14 executing predetermined data while accessing the RAM 16. Further, this control unit is configured with two timers (not shown), and these timers include a charging table corresponding to the NCC line route when the NCC line route is selected and a charging table corresponding to the NTT line route. The call time per unit charge read from is set respectively, and when each call time elapses, each timer expires.

On the other hand, in each of the cordless handsets 4 ₁ to 4 _m , the communication line 32
The call circuit 31 is connected to the signal line 33
A control unit 35, which is similar to the control circuit of the main device 1 but is composed of a smaller processor unit, a fixed memory, and a variable memory, is connected to the control unit 35 via the transmission circuit 34. In response to a control signal sent from the main device 1, in response to sending of an incoming call ringing sound, operation of each button in the keyboard 37, and operation of the hook switch HS,
The operation data indicating these situations is transmitted to the main device 1 via the transmission circuit 34. Further, the display 36 displays various information such as a differential charge display as described later.

The transmission circuit 34 has a power source separating function, and the signal line 3
The power supplied from the main device 1 side is extracted via 3 to stabilize the power, and then the power is supplied to each required part as a local power supply.

This button telephone device has an outside line incoming call regulation function for displaying an incoming call to a specific outside line on a button telephone set without incoming call regulation, and a transfer operation of the button telephone which responded to the outside line incoming, so that it can be sent to any button telephone. An external line transfer function for performing external line transfer is provided.

In such a configuration, the operation of this embodiment will be described below with reference to the flowcharts of FIGS. 1 (a) and 1 (b).

FIG. 1 shows a program for sending a dial signal by the CPU 14 of the main unit 1, and this program is a ROM.
It is stored in 15.

In the figure, the CPU 14 determines whether or not there is a call request from the subscriber from the keyboard 37 of the key telephone 4, that is, whether or not a dial signal is received (step 101), and the dial signal is not received. In this case, it is determined whether the call is an on-hook end call (step 10).
2). Then, in the case of the end of the call, a series of the end of the call process is performed (step 103), and when it is not the end of the process, the processes of step 101 and the subsequent steps are repeated.

When the CPU 14 receives the dial signal, it determines whether the dial signal is the first digit signal (step 1
04) If it is the signal of the first digit, it is further judged whether or not this dial signal is "0" (step 105). If it is "0", this signal is temporarily stored in the RAM 16 as an out-of-town dial signal. Save processing is performed (step 10
6) Then, the processing from step 101 onward is repeated again. If the dial signal is not the first digit signal in step 104, it is determined whether this signal is the fourth digit signal (step 107). If the dial signal is less than the fourth digit, the dial save process described above is performed (step 108), and the processes from step 101 onward are repeated again.

If the dial signal is the fourth digit in step 107, the area where the called party is located is determined from the entered four-digit long-distance dial number, and the NTT line route charging table and each NCC stored in the RAM 16 are determined. The charging table is searched for each line route, and the cheapest route is determined from among several types of line routes to this area (step 10).
9). Then, it is judged whether or not the line based on this search judgment result is the NCC (step 110), and if it is the NCC, the NCC line is selected (step 111), and the access dial to the NCC judged in step 109 is performed. A signal is sent (step 112), and the saved out-of-town dial signal is sent to the outside line 2 (step 11).
3).

On the other hand, if the input dial signal is not "0" in the judgment of step 105, it is judged that the call request from the key telephone 4 is for the local call, and the NTT line is immediately selected (step 114). ) The input local dial signal is sent to the outside line 2 (step 115).

Then, it is subsequently determined whether or not a dial signal has been received from the key telephone 4 (step 116), and if received, the received dial signal is sent to the outside line 2 (step 117), and then received again. If not, it is immediately determined whether or not it is the next processing step, that is, the ending call (step 118). If the result of this determination is the end of the call, the end of call process is performed (step 119). If the end of the call is not completed, it is determined whether or not the called party answers (step 120), and the other party answers. If not, step 116
The process is returned to and the above process is repeated.

When the other party responds, the CPU 14 next determines whether or not the currently selected line is the NCC line (step 1).
21). If the NCC line is not selected, the call time per unit charge (10 yen) is extracted from the charge table for the NTT line (step 122), this call time is set in the charge timer for the NTT line, and this timer is started. (Step 123). Then, it is judged whether or not this timer times out (step 124),
If the time has not expired, it is determined whether or not the call has ended (step 125). If the call has not ended, the process returns to step 124, the timer state is determined again, and the above-described processing is repeated. Then, when the charging timer for the NTT line times out, the charging display (call charge) for the NTT line displayed on the display circuit 36 of the key telephone 4 is updated (step 126), and the charging for the NTT line again. The timer is started (step 127). Further, in step 125, it is judged whether or not it is the end of the call, and if it is not the end of the call, the above processing is continued, and if it is the end of the call, a series of end of call processing is performed (step 128).

On the other hand, if the NCC line is being selected in step 121, N
The call time per unit charge is taken out from the billing table for the CC line (step 129).
The call time per unit charge is taken out from the charge table for the line (step 130). Then, each talk time is set in two timers for the NCC line and the NTT line, and these timers are started (step 13
1) First, it is judged whether or not the charging timer for the NTT line is up (step 132). If this timer does not expire, it is determined whether the timer for the NCC line will expire next (step 133). If this timer has not expired, it will be determined whether the next call is over (step 133). 134), if it is not the end of the call, the process returns to step 132.

Then, when the timer for the NTT line times out, a unit charge of 10 is charged to the charging register for the NTT line.
Yen is added (step 135), the difference between the NTT line charge register and the NCC line charge register is calculated, and the difference charge resulting from this calculation is displayed on the display circuit 36 (step 136). Then, the charging timer for the NTT line is restarted (step 137), and the process proceeds to step 133. Then, in this processing step 133, the NCC
When the line charge timer expires, add 10 yen to the NCC line charge register (step 13
8) The difference between the charging register for the NTT line and the charging register for the NCC line is calculated, and the difference charge resulting from this calculation is displayed on the display circuit 36 (step 139). Then, the charging timer for the NCC line is restarted (step 140), and the process proceeds to step 134. Then, in this processing step 134, if it is not the end of the call, the processes in and after step 132 are repeated, and if it is determined that the end of the call is completed, the end of the call process is performed (step 141).

FIG. 3 is a flow chart showing the latter half of the operation of an embodiment of the invention according to the second claim of the present application, and the first half of this operation is the same as the flow chart shown in FIG. 1 (a) of the above-mentioned embodiment. This is exactly the same as the processing of steps 101 to 120 (processing up to connector A), and the flowchart of this portion is substituted in this figure. The configuration of this embodiment is similar to that of the block diagram shown in FIG.
The display circuit 36 is provided with a switch for switching between a call charge display and a difference table charge display.

In the flowchart of FIG. 3, N in step 121
After determining whether or not the CC line is being selected, the state of this changeover switch is read (step 151), and when the state of this switch is set to the differential charge display side of the switch, FIG. 1 (b) Steps 129 to 141 that are the same as the steps shown in FIG.
The difference charge from the C line is displayed. When the switch is set to the call charge display side, the call time per unit charge is taken out from the charge table for the NCC line (step 152), and this call time is set in the charge timer for the NCC line and this timer is set. Is started (step 153). Then, it is determined whether or not this timer times out (step 154), and if not, it is determined whether or not the call ends (step 15).
5) If it is not the end of the call, the process returns to step 154 to judge the state of the timer again and repeat the above-mentioned processing. This NC
When the charge timer for the C line times out, the charge display (call charge) for the NCC line displayed on the display circuit 36 of the key telephone 4 is updated (step 15).
6) Then, the charging timer for the NCC line is started again (step 157). Further, in step 155, it is determined whether or not the call is the end call, and if it is not the end call, the above process is continued, and if it is the end call, a series of end calls is performed (step 15).
6).

In the above-described embodiment corresponding to the first claim, when the NCC line is used, only the differential charge is displayed and the call charge is not displayed. However, in the embodiment corresponding to the second claim. Since the switch for switching between the call charge and the differential charge is provided, the call charge can be displayed even when the NCC line is selected.

Although the above-described two embodiments have been described with respect to the key telephone device, they may be independent telephones instead of the key telephone device, and the NCC line route may be from one company or from multiple companies. The same effect as that of the above embodiment is obtained.

〔The invention's effect〕
