In addition, the destination number selection button switch for automatic dialing and the numeric keypad for speed dialing were independent of the station line selection button switch.

Therefore, in the above-mentioned conventional electronic button telephones, if the maximum number of station lines that can be accommodated differs, the number of station line selection buttons of the telephone, the housing, shape, and dimensions will differ. It is necessary to manufacture and manage many types of telephones. Therefore, quality control of parts and finished products is extremely difficult, leading to increased costs. In addition, if the number of station lines to be mounted is less than the number of station lines that can be stored, an unused station line selection button switch is provided, which is inconvenient due to confusing operations, and unnecessary parts are installed. This also had the disadvantage that users ended up using more expensive telephones than necessary.

[Purpose of the invention]

The present invention has been made in view of the above points, and uses a case provided with the same number of station line selection button switches regardless of the number of installed station lines, and implements a station line number selection button switch. By using the surplus central office line selection button switch as a destination selection button switch for automatic dialing, we can reduce the number of telephone models, share the telephone housing, simplify manufacturing and management, and improve functionality. The purpose of the present invention is to provide a button telephone device with improved performance.

[Summary of the invention]

The gist of the present invention is that in a button telephone device consisting of a main device and a plurality of telephones each having a plurality of telephone line selection button switches, a central office line circuit provided in a telephone housing automatically switches uninstalled central office line selection button switches.

t8 completed. Note that telephone 2-2. ,．． 2-n is similarly configured.

In the above configuration, the case where a telephone call is made from the telephone set 2-1 will be explained based on the flowchart 1 of FIG. 3. The figure (,) shows the telephone side, and the figure (b) shows the main device side. In FIG. 3, the telephone 271 side has implementation data for the central office line, and has a function that can determine whether or not the central office line circuit corresponding to the central office line selection button switch pressed on the telephone 2-1 is installed. Flowchart 1 for the case is shown below.

First, when the caller picks up the handset and presses the central line selection button switch in which the return circuit of the key group 18 is mounted (step 31), the key press information detection unit 19 detects that the button switch is the central line selection button switch. Step 32) If it is determined that the station line selection button switch is pressed information, then it is determined whether or not this station line selection button switch is a station line selection button switch whose station line circuit is not implemented. (Step 33). If it is due to the installed station line selection button switch, the data conversion processing unit 2
0, the station line selection button switch press information is converted into retrace line selection code data (step 34), and this station line selection button switch code data is used for data transmission and reception (i circuit 21
．． 17 to the control processing unit 14 (step 3
5). The control processing unit 14 determines whether or not it is a central office line selection code (Step 36), then determines whether the relevant central office line is vacant (Step 37), and if vacant, converts the central office line selection code data into a central office line acquisition signal. In step 38), the outgoing central office line is acquired by the communication path switch 16. In step 37,
If it is not vacant, processing such as 1-incoming call processing and floor reservation processing is performed (step 40). Next, when the dial button switch is pressed, the press information is converted into a dial key code signal in step 34 through steps 31 and 32 as described above.

This dial key code signal is sent to the control processing section 14 through step 35 as described above. The control processing unit 14 determines in step 36 that this dial key code is not the return line selection code data, and further determines that it is not an automatic dial code in step 41, and sends this dial key code to the sender 12, and sends the dial key code to the station line circuit group 11. A dial message 1 is sent to the captured central office line (step 47). When the other party picks up, call.

The above is a normal dial call, but next, press the return line selection button switch, which does not have a central office line circuit installed.

This section explains how to make an auto-dial call.

When the central office line selection button switch in which the central office line circuit is not installed is pressed, the process goes through steps 32 and 33 to determine whether or not the telephone 2-1 is capturing the central office line (step 42), and if it is not, Since automatic dialing is not possible, the press information for the return line selection button switch is invalidated. In step 42, if the central office line is captured, the data conversion processing unit 20 converts this unimplemented central office line selection button switch information into an automatic dialing code signal.Step 43
), and sends it to the control 1J3A management department 14 via step 35. The control processing unit 14 determines in step 36 that the data is not central line selection code data, and further determines in step 41 that it is an automatic dial code. Subsequently, the control processing unit 14 accesses the memory 13 (Step 42), converts the automatic dialing code signal into dialing information, and converts the automatic dialing code signal into a dialing signal at the sender 12 (Step 45), which is captured via the office line circuit group 11. A dial signal is sent to the central office line (step 46). The above is a case where the telephone 2-1 side has the implementation data of the central office line and has a function that can determine whether the central office line selection button switch pressed on the telephone 2-1 is installed. Next, a case will be described in which there is no implementation data on the telephone side and the main device side 1 has the function of determining whether or not the pressed office line selection button switch is installed.

FIG. 4 is a flowchart showing the operation of the telephone device shown in FIG. 2, where (a) shows the telephone side and FIG. 4(b) shows the main device side.

When the station line selection button switch on which the station line circuit is mounted among the button switches in the key group 18 is pressed (step 51), this button switch press information is detected by the key press information detection unit 19, and data conversion is performed. The processing unit 20 converts it into code data (step 52). This code data is sent to the control processing section 14 of the main device 1 via the data transmission/reception circuit 21.17 (step 53). The control processing circuit 14 determines that the sent data is code data based on information on pressing the central office line selection button switch (step 54), and determines that the central office line selection button switch is not unmounted. Step 55), furthermore, it is determined whether the office line is vacant or not (Step 56), and if it is vacant, a retrace signal is sent to the communication path switch 6 (step 57), is captured (step 58). If the central office line is not vacant in step 56, incoming call processing and hold processing are performed (step 5).
9). Next, when the button switch is operated by dial operation, it is converted into code data via step 5I and step 52, and then passed through step 53 to the control processing section 14 of the main device.
sent to. The control processing unit 1.4 determines that the transmitted code data is not based on the retrace selection button switch press information (step 54), and further,
It is determined that this code data is from the dial button switch (step 6o), and it is sent to the sender j2, and the sender 12 converts it to dial number 48 (step 61), and dials the office line via the office line circuit group 11. A signal is sent (step 63).

If you wish to make an automatic dial call using a return line selection switch whose central office line circuit is not implemented, press the uninstalled central office line selection button switch and the code data will be sent to the control processing unit 14 through steps 51, 52, and 53. Sent out. The control processing unit 14 determines whether or not this is caused by pressing the central office line selection button switch (step 54), determines whether or not the central office line circuit is not installed (step 55), and further determines whether the telephone Although the station line is captured, it is difficult to judge step G.
4) When the central office line is captured, the memory 13 is accessed to convert this automatic dialing code data into dialing information.Step 65) Send it to the sender 12, and the sender 12 converts it into a dialing signal.Step 66) Office line circuit group 11
The signal is transmitted to the captured central office line via the station (step 63).

If the return line is not captured in step 64, the code data is invalidated.
