In this diagram, each power supply unit for control and operation is shown for simplification, and for the sake of simplicity,
Since the internal configuration of KT-m is the same as that of the key telephone KT-1, illustration thereof is omitted.

The KEY included in the button telephone has a keyboard that includes line selection keys (hereinafter referred to as line keys), numeric keys, speed dial keys (hereinafter referred to as speed keys), redial keys, and key contacts such as * and #. There is. LED is a light emitting diode used as an indicator light to indicate the usage status of central office lines, extension lines, etc.
HS is a switch.

In addition, the control circuit (processor) of the main device ME
The CPU uses a program stored in advance in the read-only memory ROM and the button telephone KT-1...
...The control circuit (processor) KPU of the KT-m operates according to a program stored in advance in the read-only memory OM.

The sound source circuit TONE is a dial tone
Office line ring tone (ring tone from the office line in general incoming call mode), extension ring tone (other key telephone KT-j)
It has the function of generating a ringtone (from a ringer) and a hold tone.

The control circuit CPU includes an incoming call detection circuit INC-1,...
...By sequentially referring to INC-n, which central office line CO-i receives a call is constantly monitored. The clock circuit CLK measures the talking time of each key telephone KT-j, the ringing time (the time from when the ringtone starts ringing until when the call is answered), etc. In addition, in the general incoming call mode, when a call is received from the central office line, which of the key telephones KT-1 to KT-m is to play the central office line ringtone is specified in advance in the RAM. There is. Here, it is assumed that the key telephone KT-m is the key telephone.

While operating in general incoming call mode, central office line CO-1,...
...When there is an incoming call to any CO-n (CO-i),
Incoming call detection circuit INC of the corresponding station line circuit COT-i

Send to.

In response to this, the control circuit CPU disconnects the tone source circuit TONE from the communication path network SW, and forms a loop in the central office line circuit COT-i.
Next, the office line CO-i is connected to the speech circuit KSL of the button telephone KT-m designated for ringing via the office line circuit COT-i, the speech path network SW and the transformer T-1m.

In this way, the central office line CO-i and the key telephone
A communication path between KT and m is formed.

Now, the present invention, which allows re-dialing to be performed with a complete one-touch operation in such a button telephone device, will be described in detail below.

First, when making a call from the regular button telephone KT-1, lift the handset and turn the switch.
When you turn on the HS and then press the line key on the keyboard KEY (the reverse operation is also possible), the control circuit KPU of the button telephone KT-1 detects this and turns on the transmitter/receiver circuit KXR, transformer T6, and transformer on the main unit ME side. T-21, transmits the line selection information to the control circuit CPU on the main device ME side via the transmitter/receiver circuit XR.

In response, the control circuit CPU switches the station line circuit COT.
-1 to form a loop, and then the telephone call circuit KSL of the button telephone KT-1 was operated to make a call via the office line CO-1 through the office line circuit COT-1, the communication path network SW and the transformer H-11. , and have the control circuit KPU light up the light emitting diode LED corresponding to the station line CO-1 via the transmitter/receiver circuit XR on the main equipment ME side, the transformer T-21, and the transmitter/receiver circuit KXR on the KT-1 side. Send control commands.

In this way, the central office line CO-1 and the key telephone
A communication path for KT-1 will be established. Next, when the operator presses the dials x and y in sequence, dial pulses corresponding to the dials x and y are sent to the office line CO-1 to call the other party.

When using the abbreviated dialing function, by pressing the abbreviated key corresponding to the pre-registered number of the other party, it is possible to easily make a dialing call without having to press dials x and y each time.

If the other party answers, the call to the key telephone KT-1 will be made, but if the other party is busy or does not answer, the phone will switch off when you hang up the handset.
When the HS is turned off, the control circuit transmits the down-down information.
KPU, CPU detects each circuit KXR, XR, COT
-1, Clear SWC, SW, KSL, etc. and return to the initial state.

Next, there may be a case where you want to dial the other party again, such as when the other party does not respond, but according to the present invention, all the various information (hook information, dial information, etc.) operated by the operator earlier will not be cancelled. will be registered in the manner described below.

First, the redial registration function will be explained with reference to the flowchart of FIG. Here, registration will be explained using an example of registration using a speed dial function instead of registration by pressing dials x and y, but the present invention is not limited to this.

In Fig. 3, the CPU in the main device ME monitors whether the line key of a certain button telephone has been turned on (step S1), and if it determines that it has been turned on, the CPU in the main unit ME will write the line key in the redial registration area in the RAM. The selected line key is registered (step S2).
Next, it is determined whether or not the file has been loaded (step S3).
This is converted into a press of a dial key and registered in the re-dial registration area (step S4).

Here, we converted the hook-up to an on-hook/dial key press because the hook-up operation always recognizes human operation, so if you include the hook-up operation in the redialing operation, you can re-dial with just one touch operation. This is because it becomes impossible to perform a dialing operation.

Next, a function is performed to capture the line corresponding to the line key turned on in step S1 (step S5). Subsequently, the CPU determines whether or not the abbreviation key has been pressed (step S6), and if the answer is yes, the abbreviation key press is registered in the re-dial registration area in the RAM (step S7). Next, when the operator presses the dials x and y in sequence, the dials x and y are displayed in the registration area.
is registered (steps S8 and S9).

Thereafter, data corresponding to the contents of the dials x and y is dialed (step S10), and a response is received from the other party. Next, I wonder if the episode has come to an end or not.
In other words, it is determined whether or not a downturn has occurred (step S11), and if it is determined to be yes,
The series of redial registration processing ends.

As described above, according to this embodiment, redial registration can be performed with the image of an abbreviated dialing operation, and execution of redial registration is easy.

Figure 4 shows that the main device ME is operated by the above functions.
A conceptual diagram of registration contents corresponding to one key telephone KT registered in the redial registration area of RAM is shown. From this figure, in the redial registration area,
Press the central line key corresponding to the address, on-hook
It can be seen that the data of dial key presses, speed dial key presses, dial x key presses, and dial y key presses are stored as encoded values.

In addition, in the redial registration function mentioned above,
In order to prevent redial area registration due to erroneous or fake operations, monitor the time from the start of redial registration to the acquisition of the line in step S5 using a timer, etc., and when the time exceeds a predetermined time, a false It can be made to be determined that it is a manipulation.

Next, the functions at the time of redialing will be explained in detail with reference to FIG.

The CPU in the main device ME monitors whether the re-dial key is pressed by the operator when it is idle (steps S20, S2).
1) If it is determined that the redial key has been pressed, an operation is started to read the registered contents from the redial registration area of the button telephone KT corresponding to the redial key (step S22). Next, dialing operations are automatically performed in the order performed in redial registration as follows.

That is, first, a line key is pressed or a process equivalent thereto is executed (step S23). next,
An on-hook dial key is pressed, or an equivalent process is executed (step S24). It is clear from the above description that the function of the pickup is thereby performed.

Subsequently, pressing the abbreviated key, pressing the dial x, pressing the dial y, or processing equivalent to these is sequentially executed (steps S25, S26, S27). When these processes are completed, the abbreviated dialing operation has been completed, so the control device in the main device ME automatically dials data corresponding to dials x and y (step S28).
Then, it is determined whether or not there is a response from the other party (step S29), and the process ends when a response is received or when there is no response for a predetermined period of time (step S30).

As is clear from FIG. 5, according to this embodiment, the same dial number as the previously dialed number can be automatically re-dialled with a single press of the re-dial key.

In the above embodiment, the redial registration area is provided in the RAM in the main device ME, but the present invention is not limited to this, and the redial registration area is provided in the storage device of the control circuit of each key telephone KT. , transmitting and receiving circuit KXR, transformer T6, transformer T-
₂ m and the transmission/reception circuit KR on the main device ME side to the control circuit CPU on the main device ME side.

(Effects of the Invention) As is clear from the above description, the following effects are achieved according to the present invention.

(1) Since the redialing operation can be performed with just one touch by pressing the redialing key, there is no need to bother with the redialing operation.

(2) Since re-dial registration can be performed with the image of an abbreviated dialing operation or an equivalent dialing operation, even a person operating a terminal telephone for the first time can easily handle it.
