In this case, the display DP uses a fluorescent display tube, and in order to obtain the necessary power, the +12V local power supply is converted to -20V by the converter CNV.

-25■, Oyohi, converted to AC4.2V and supplied to the display device DP.

Therefore, the telephones T E L t to T E L n
All operating conditions are sent to the main unit KSU as operation data, and control data is sent based on the judgment of the control unit CN Tm. The data is held in the memory of CNTt, and the control unit CNTt controls each part accordingly.

In addition, the main unit KSU and the telephone TETL+ -TEL
In this case, data transmission and reception between
Each data is indicated by a code generated by a pulse-like change in tl, which is performed by changing the line voltage of LSn.

Figure 3 is a flowchart of the control situation by the control unit CN T m of the main unit KSU, in which data is transmitted and received with the telephones N place I to place n transmission processing 〃1o1 stain removal device I to place n, and the received data After storing 0N=1 in the memory, it is stored in the counter configured in the processor of the control unit CNTm.
“After setting 102, N reception data processing〃111
Deciphers the operation data received from the telephone device I in a small memory and displays whether or not there is data related to the display on the display DP in the information generated based on the data in the data. Do you have data? “Judging by 112, this

The answering loudspeaker key or the like has been operated, and in order to send the control data that commands the display according to these, the turtle and other display processing 132 is performed, but if YE of step 131
Depending on S, the memory is checked to determine whether the telephone stack Capturing one line? Judging by 〃141,
Assuming YES to this question, whether or not a specific key determined for dialing number memo in the function key FK, or the "+" or "arrow" key in the dial key DK determined for the same purpose was operated. One memo key operation? "142 checks according to the contents of the memory, and if it is YES, the corresponding dial buffer area/display data cellar in the memory)" stores the dial number according to the operation of the dial key DK, and then In order to display this dial number on the display device DP, a corresponding 1 transmission buffer area/display data set 144 of the memory is performed, and preparations are made to transmit this as control data.

Note that if step 142 is NO, the normal dialing in the line capture state is not possible, and the 1-dial transmission is 1.
45 controls the dial output path DS of the captured line;
Sends a dial signal 0 Also, if step 112 is NO, do you want to immediately acquire one line? /1151 and determines this based on the contents of the memory, and depending on the YES response, the corresponding ant dial buffer area/content cloth b? p
Check 152 and send dial according to the contents of the bed dial buffer area assuming YES.
161, controls the dial circuit DS of the captured line according to the dial number in the dial buffer area, sends a dial signal, and then
Perform Clear 162.

On the other hand, in response to NOK in step 151, the process immediately moves to other processing 111, performs control processing according to the operation data, such as calling processing between extensions, and sets the counter in step 102 to 'N=N. -1-1" 172, repeat steps 111 and subsequent steps while %N=n?/'173 is No, and step 113 is YE.
If S and n, then N (g1 line processing) After checking the contents of the υ memory by j81 and controlling queuing registration in response to the occurrence of an idle line, a timer in the processor will start the next transmission. Timing? //182 is monitored, and in response to YES, steps 101 and subsequent steps are repeated.

Therefore, if the processor does not check the memory contents to monitor the multi-line acquisition state, and if the result is that the line is not acquired, step 141 will be NO, and the multi-line acquisition state will not be monitored in response to the operation of the dial key DK. The dialed number is stored in step 143 and given to the telephone stack (in step 144 and step 101), and this is displayed on the display DP, and if the line is in a state of capture, step 151 becomes YES; If YES is determined in step 152, a dial signal corresponding to the stored dial number is sent to the line in the captured state (in step 161).

Therefore, before capturing the line, operate the dial key DK, confirm the dial number corresponding to the dial on the display DP, capture the line, and send out a dial signal according to the confirmed dial number. This makes it easier to prevent erroneous calls due to erroneous operations, and if the same operation is performed after queuing registration, dialing will be performed in the same way when the line is captured after a vacant line occurs. , If a specific key is operated during a call after the line is captured, and then the dial key DK is operated in accordance with the dial number to be memorized, steps 141 and 142 become YES,
The dialed number is memorized in step 143, and is given to the telephone device in steps 144 and 101, and displayed on the display DPK. When the line is captured, a dial signal corresponding to the dial number stored in step 161 is sent to the captured line via YES in steps 151 and 152.

Therefore, the dial number notified by the call with the guide mill etc. is memorized by operating the specific key and the dial key DK, and is also displayed on the display DP, and if the line is captured again, it will be memorized. Since the call is made automatically using the dialed number, there is no need to record the dialed number on memo paper, etc., making it extremely convenient to use.

FIG. 4 shows the control unit CNT of the telephone equipment, ~TE Ln.
This is a 70-chart of the control situation according to t.

In this case, according to the memory/display data set 222,
The display data is stored in the memory, thereby display device DP
After displaying the dial number, the display lamp PL is turned on and off, the speaker SP is made to sound, etc., and steps 201 and subsequent steps are repeated.

The interrupt routine (9) is repeated, for example, at a cycle of 5 m (8), and the output of each operation unit is captured by the 1-operation output detection unit 301, and the output is detected by comparing it with the corresponding previous data in the memory. Is there an output change? 〃Judging 302,
If this is YES, 1 memory/transmission data set〃3
13, the dial key DK and function key FK caused an output change.

Data corresponding to the hook switch H8 etc. is stored in the memory, and preparations are made to transmit it as operation data in step 201. Therefore, while the operation status of each operation section is sequentially transmitted as operation data in step 2, If dial number display data is included in the received control data, this is displayed on the display DP.

Note that line capture is performed by operating the line key during function key FK and going off-hook, or by operating the line key and similar amplification key operation, assuming that there is an empty line in ~Ln, and releasing the line capture. is performed by re-operating the on-hook or loudspeaker key,
Queuing registration is performed on-hook or off-hook by operating a specific number on dial key DK or operating a queuing registration key among function keys FK.

If automatic line acquisition is possible, it is carried out by operating the off-hook or voice-receiving key, or by operating the off-hook and a specific number on the dial key DK, or by operating a specific key among the function keys FK.

However, the configurations shown in FIGS. 1 and 2 can be arbitrarily selected depending on the conditions, and the dialing number may be stored in the control unit CNTt, and the dialing circuit DS may be installed at the telephone set. The steps shown in FIGS. 3 and 4 can be replaced or changed, or unnecessary steps can be omitted depending on the situation.

Further, the same applies not only to button telephone devices but also to a single function telephone with a display, and as the monitoring means, a hook switch contact, a contact of a DC loop closing relay, etc. may be used. As the storage means, not only a memory but also a register etc. may be used as desired.As the sending means, a processor and a dial circuit DS, or a sending control circuit configured by a combination of various logic circuits may be used. Various modifications, such as good, are up to you.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, the memorized dial number is displayed on the display, and a dial signal according to the memorized dial number is automatically sent out in response to line capture. This prevents erroneous dialing due to erroneous operation of the dial keys, and makes dialing operations easy and reliable.
Significant effects can be obtained.
