However, these functional telephones have traditionally been designed to send dial signals at the same time as displaying according to the operation of dial keys.The dial number displayed on the display confirms the dial number operated. After that, I could not send the dial signal,
If the dial key is operated incorrectly, the wrong dial signal is sent out as it is, and the dial number displayed on the display is meaningless for confirmation of the dial operation.

In addition, in the recent key telephone device, when the accommodated telephone line is fully busy, an operation called queuing registration can be performed to automatically call the registered key telephone in response to the occurrence of an empty line. In preparation for this, the dialed number to be sent is stored and displayed in advance after this queuing registration, and the dialed number stored when the line was seized after being called in response to the occurrence of an empty line. Therefore, a function capable of automatically sending a dial signal is also required.

On the other hand, to the line terminal Ts to which the signal line Ls is connected, the power supplied from the main unit KSUs via the signal line Ls is stabilized, and the power is supplied to each part required as a + 12V, + 5V local power supply. The circuit PS is connected, and the transmission circuit SRt is also connected. Through this, the control unit CNTt transmits operation data to the main device KSU and receives control data from the main device KSU. .

Also. Although it is similar to the control unit CNTm of the main unit KSU, the control unit CNTt smaller than this is provided with the outputs of the dial key DK, various function keys FK, and the fax switch HS ² , and these operations are performed. The operation data corresponding to the above is transmitted as described above, and based on the received control data, the loop closing circuit LC, the switch circuits SW ₁ and SW ₂ , the oscillator OSC, the indicator light PL including a plurality of light emitting diodes, and the character display. The display DP using the device is controlled, and the lines L _{1 to} Ln are caught or held by turning on or blinking the indicator light PL, and the loudspeaking state is displayed by the speaker SP.

The dial number, the time and the like are displayed according to the operation of K.

In this case, the indicator DP uses a fluorescent display tube in this case, and in order to obtain the power required for this, the local power of + 12V is converted into -20V, -25V, and AC4.2V by the converter CNV, and these Is supplied to the display device DP.

Therefore, the operation status of the telephones TEL _{1 to} TELn is
All are transmitted as operation data to the main unit KSU, and the control data is transmitted according to the judgment of the control unit CNTm according to this, and this control data is held in the memory of the control unit CNTt and is used as this. Then, the control unit CNTt controls each unit.

In this case, the data transmission / reception between the main unit KSU and the telephones TEL _{1 to} TELn is performed by the line voltage change of the signal lines LS _{1 to} LSn, and each data is transmitted by the code by the pulse-like change. It is supposed to be shown.

FIG. 3 is a flow chart of the control status by the control unit CNTm of the main unit KSU, and the telephones "TEL _{1 to} TEL".
After transmitting / receiving data to / from the telephones TEL _{1 to} TELn by the "n transfer processing" 101 and storing the received data in the memory,
After setting "N = O" 102 to the counter configured in the processor of the control unit CNTm, "Reception data processing" 1
The operation data received from the telephone TEL ₁ in the memory is decoded by 11 and it is determined whether or not the information generated therein or based on the data therein is the data related to the display of the display DP "display data". Yes? “Judging by 112,
If this is YES, the telephone "TEL _N has a display?" 113 is judged based on the data in the memory,
In response to this YES, the display data is “Display clear?” 11
If 4 is judged and YES, the corresponding "dial buffer area / clear" 121 in the memory and the same "transmission buffer area / display clear set" 122 are executed to clear the display on the display DP. Prepare to send.

Then, if step 114 is NO, dial key D
Judgment "dial display data?" 131 according to the operation of K, and when this is NO, the output change of the fax switch HS ² due to off-hook or on-hook, or the line key, the hold key, the reception loud key in the function key FK Etc. have been operated, and “other display processing” 132 is performed in order to transmit control data for instructing display according to these. However, if YES in step 131,
By checking the memory, whether or not the telephone TEL ₁ has closed the DC loop for any of the lines, and is connected for dialing or making a call is determined by the "acquiring line?" 141. Judgment is made, and if YES is determined, the specific key defined for the dial number memo in the function key FK or the "#" or "*" key in the dial key DK defined for the same purpose is operated. Whether or not it has been checked by "Memo key operation?" 142 according to the contents of the memory, and if this is YES, the corresponding "Dial buffer area / display data set" 143 in the memory is used to operate the dial key DK. Therefore, after storing the dialed number, this dialed number is displayed on the display DP, so that the corresponding "sending buffer area" in the memory is displayed. -Perform display data set "144" and prepare to transmit this as control data.

If step 142 is NO, it means a normal dial transmission in the line capture state, and "dial transmission" 145.
Controls the dial sending circuit DS of the capturing line to send a dial signal.

If step 112 is NO, the line immediately moves to "line capture?" 151 to judge this from the contents of the memory.
Check the corresponding "Dial buffer area / contents?" 152 according to the YES of this, and then the YES of this
"Send dial according to the contents of the dial buffer area" 161 is performed, and the dial circuit DS of the capture line is controlled according to the dial number in the dial buffer area to send the dial signal and then the dial buffer. Perform Area Clear 162.

On the other hand, if NO in step 151, the process immediately shifts to "other processing" 171 to perform control processing according to operation data, such as calling processing between extensions, and then step 1
The counter of 02 is incremented by "N = N + 1" 172, and the steps 111 and thereafter are repeated while "N = n?" 173 is NO, and if the step 173 is YES, "line processing" 181
Check the contents of the memory with, and perform the control corresponding to the queuing registration that responds to the occurrence of an empty line, and then monitor the "next transmission timing?" 182 with the timer in the processor. Repeat steps 101 and beyond.

Therefore, the line capture state is monitored by checking the memory contents by the processor, and if the line non-capture state is set according to the result, step 141 becomes NO,
The dial number corresponding to the operation of the dial key DK is stored in step 143 and is given to the telephone TEL by step 144 and step 101, and this is displayed on the display DP, and if the line is caught, the step is set. If YES in 151, the dial signal corresponding to the dial number stored in step 161 is sent to the line in the captured state via YES in step 152.

Therefore, before dialing the line, the dial key DK is operated, and in response to this, the dial number is confirmed on the display of the display unit DP, the line is captured, and the dial signal is transmitted according to the confirmed dial number. In addition, it becomes easy to prevent erroneous transmission due to an erroneous operation, and if the same operation is performed after the queuing registration, the dial transmission is similarly performed according to the line capture after the idle line is generated.

Also, after operating the specific key during a call after line capture,
If the dial key DK is operated according to the dial number to be recorded, YES is obtained in steps 141 and 142, and the dial number is stored in step 143.
This is given to the telephone TEL by the steps 144 and 101, and the display is made by the display DP, and once the line acquisition is released and the line acquisition is performed again, the steps 151 and 152 are followed by YES to the step.
A dial signal corresponding to the dial number stored by 161 is sent to the line in the captured state.

Therefore, the dial number notified by the call with the guide board or the like is stored by operating the specific key and the dial key DK and is displayed by the display device DP, and is stored when the line is captured again. Since the automatic dialing is performed, the need to record the dial number on a memo sheet is eliminated, which is very convenient for handling.

FIG. 4 shows the control unit CNTt of the telephones TEL _{1 to} TELn.
11A is a main routine routine, and FIG. 11B is an interrupt routine. Data transmission / reception with the main unit KSU is performed by a "transmission process" 201, and a step 11
After performing the "reception data processing" 202 as in the case of 1, the "display data is present?" 211 is determined in the same manner as in the step 112, and the "display clear?" 212 is determined in the same manner as in the step 114 in response to YES. On the other hand, if this is YES, "memory / display data clear" 221 is carried out to clear the display data in the memory and set all the display on the display DP to "0".・ Display data is stored in the memory by "Display data set" 222.
As a result, the dial number is displayed on the display device DP, and then the "other processing" 231 causes the indicator light PL to be turned on, the lamp to be turned off, the speaker SP to ring, etc., and the steps from step 201 onward are repeated. .

Further, the interrupt routine of (B) is repeated, for example, in a cycle of 5 msec, the output of each operation unit is taken in by "operation output detection" 301, and "output" is made by comparison with the corresponding previous data in the memory. Is there any change? "Judging 302, this is YE
If S, the "memory / transmission data set" 313
The data corresponding to the dial key DK, the function key FK, the fax switch HS ^2, etc. which have changed the output are stored in the memory, and the step 201 prepares to transmit the data as operation data.

Therefore, while the operation status of each operation unit is sequentially transmitted as operation data by the step 201, if the received control data includes dial number display data, this is displayed by the display device DP.

Note that line capture is performed on the premise that there is an empty line in the lines L _{1 to} Ln by the line key operation and the off-hook operation in the function key FK, or the line key operation and the similar reception loudspeaker key operation. Cancellation is performed by on-hook or re-operation of the listening loudspeaker key,
The queuing registration is performed by operating a specific number on the dial key DK or operating the queuing registration key in the function key FK on or off.

When the line can be automatically captured, it is performed by operating the off-hook or receiving voice amplification key, operating the off-hook and dial key DK with a specific number, or operating the specific key in the function key FK.

However, the configurations shown in FIGS. 1 and 2 may be arbitrarily selected according to the conditions, and the dial number may be stored in the control unit CNT _t , and the dial circuit DS may be connected to the telephones TEL _{1 to} TELn. Even if it is provided, it is the same,
In FIGS. 3 and 4, the steps can be interchanged or unnecessary steps can be omitted depending on the situation.

Further, the same applies not only to the key telephone device but also to a single function telephone with a display. As a monitoring means, a fax switch contact, a contact of a DC loop closing relay, etc. may be used. Not only a memory but also a register or the like may be applied as the transmission means, and as the transmission means, in addition to the processor and the dial circuit DS, a transmission control circuit configured by combining various logic circuits may be used, and various modifications are made. Is free.

〔The invention's effect〕

As is apparent from the above description, according to the present invention, since the stored dial number is displayed on the display and the dial signal according to the stored dial number is automatically transmitted in response to the line capture, the dial key In addition to preventing erroneous call originating from erroneous operation, the dial call operation becomes easy and reliable, and a remarkable effect can be obtained in various function telephones.
