Keypad 10, to decode the signal resulting from
It is connected to the ROMs 121 and 122 and the RAM 13 and specifies an address to access the code 1, 2, and No1 data. The switch 19 is used to selectively access any of the function codes 1 and 2 or No. 1 data.
1, 122 and the RAM 13.

When the input voltage is lower than the detected special voltage, the low power detector 14 is connected to the switch 19 to operate the first memory 12 (ROM 121 or 122) which outputs the function code 1 or 2. I have. The data loss detector 15 is connected to the switch 19 to detect when the No. 1 data has been lost.

The flag generator, that is, the data empty flack generator 16 is an empty flag when the RAM 13 does not store No. 1 data.
A flag such as an occupation flag for storing one data is provided. The switch 19 is connected so that the RAM 13 outputs No1 data, or the ROM 121 or 122 controls the output of code 1 or 2.

The bus 18 has a RAM 13 and a ROM 121 for transmitting / receiving No1 data or code 1 or 2.
And 122. Tone pulse generator 17
Are connected to the bus 18 so as to receive and output what the bus 18 transmits.

The invention is characterized in that the codes 1, 2 and No1 data are activated by a function key, ie the M1 key, and are distributed on the address line AD1. This function is performed by pressing a service or a key (hereinafter, referred to as an SV key of the keypad 10).

The detailed description of the preferred embodiment of the invention can be divided into four parts each. Rule 1 When the telephone accessing the function code is newly applied power so that the telephone set is empty data, that is, no data is stored in the RAM 13, and the input voltage is stored in the RAM 13.
When the user presses the M1 key when the stored data is reduced to the critical voltage so as to lose the data, the RAM 13 which outputs the data corresponding to AD1 is output to work, and the central office via the bus 18 is output. The switch 19 operates the ROM 121 or 122 so that the switch 19 sends out the code 1 or 2 corresponding to AD1 so as to send out to the tone pulse generator 17 which outputs the same to the tone pulse generator 17. The decision to send one of codes 1 and 2 depends on whether or not code 1 was sent, for example, if code 1 was not sent, code 1 would be sent, and if code 1 had already been sent, Code 2 is sent out. Rule 2 If the data stored in the RAM 13 is lost or has an abnormal change due to the effects of static electricity and special adverse effects such as pressing of the M1 key, the switch 19 is set to the AD state.
ROM 121 or 122 is operated to send code 1 or 2 corresponding to 1 to bus 18. Rule 3 If the data in RAM 13 is empty and M1 key is pressed,
The switch 19 activates the ROM 121 or 122 to send the code 1 or 2 corresponding to 1 to the bus 18. As another method, when there is data stored in the RAM 13 by a normal method, that is, when there is No1 data corresponding to the address AD1 and the M1 key is pressed, the RAM 13 is operated so that the switch 19 sends out No1 data. Rule 4 One key of the keypad 10 is a service key, i.e., an SV key, which is a key that forms another function.
Other keys, such as one key, can be combined and used. When the SV key is pressed, the function code stored in the ROM 121 or 122 is forcibly output.

For example, when the SV key and the M1 key are continuously pressed, the switch 19 or the ROM 121 or 122 is operated, and the code 1 or 2 is output. When only the M1 key is pressed and the data No. 1 is stored in the RAM 13 as usual, the data No. 1 is output.

The above four rules will be described in more detail with reference to the block diagram shown in FIG.

When the telephone voltage is reduced to a critical value that could cause the data stored in ROM 13 to be lost, low power detector 14 notifies switch 19 to set the output in ROM 12. An LPD signal is provided. The data loss detector 15 detects whether the data stored in the RAM 13 is lost. If there is a loss, a RAM-LOSS signal is provided to notify the switch 19 that the data loss detector 15 causes the ROM 12 to output.

The flux generator 16 is provided with a flux indicating the storage status of the RAM 13. When there is data stored in the RAM 13, the RAM 13 generates a RAMW signal to notify the generator 16 of the flux so that a special flux such as a RAM-EMP flux as “0” or “1” is set. Is done.

According to the RAM-EMP provided here, the flux generator 16 is supplied with a RAM-EMP signal for informing the switch 19 of the storage state of the RAM 13. When the switch 19 is informed that there is empty data stored in the RAM 13, the ROM 12 or R
The output is determined by the AM 13. The user has a function key,
That is, when the M1 key is pressed, a dial signal is sent to the address decoder 11 by this. When the dial signal is sent to the address decoder 11, the address decoder 11 causes each address line corresponding to each data, that is, each R, so that AD1 is designated.
The AM 13 and the ROM 12 are connected.

Data stored in RAM 13 and AD1
Is notified to the switch 19 by the flack generator 16 that the data corresponding to is not empty data, the low power detector 14 detects a normal voltage value without a voltage drop. R in which the data loss detector 15 stores the data No. 1
The normal storage state of the MA 13 is detected, and the data stored in the RAM 13 and the No. 1 data corresponding to AD1 are sent to the tone pulse generator 17 via the bus 18 and output in either tone or pulse mode. These are performed according to the operating conditions based on the above-described first to third rules.

In addition, the function code, code 1 or 2 As described in rule 4, when accessed, the user must take the step of pressing the service key, ie the SV key, followed by the function key. Ie, M1
You have to press a key.

Therefore, when all special service function codes, ie, ^* A7655431 #, try to access the central office to request a call diversion service, the user may add the initial code " ^* A" to the first SV and M1. The key, the M1 key for outputting the telephone number "7655431" and the SV and the M1 key for outputting the tail code "#" can be continuously pressed. Here " ^* A""76543"
21 "and"#"are defined before, and" ^* A "
D1 is stored as a code 1 in the ROM 121, and “7655431” is stored in the ROM 121 as R1 corresponding to AD1.
Which is stored as No1 data in MA13,
“#” Is stored in the ROM 121 as code 2 and AD
This corresponds to 1. The special service of call diversion is performed in this way. Pressed keys are SV, M
1, M1, SV and M1 keys. During these steps, only two keys are pressed, namely the SV and M1 keys.

Another example of the special service function is a reminder service. The clock value, that is, 1400 indicating the time of PM 2.00 is the address line AD2 of the RAM 13.
The initial code “ ^* B” stored as No. 2 data corresponding to the
The tail code "#" stored as the code 1A corresponding to the address line 21 and displayed as the prompting service is stored as the code 2A corresponding to the address line AD2 of the ROM 122. Code 1A, Code 2
A and No. 2 data are respectively stored in the address line AD2.
One of these codes and data is only accessed by pressing function key M2 to separate it only. The reminder service is SV, M2, M2, SV and M2 continuously.
This is done by pressing a key.

The user can achieve the same state by performing the above-mentioned operation without pressing the SV key. The user selects N corresponding to the address line AD1 of the RAM 13
It is possible to store empty data of No2 data corresponding to the telephone number “7655431” corresponding to the address line AD2 of the o1 data RAM 13.

The address decoder 11 decodes a signal generated from the key M1 and performs AD control so as to access one of data No. 1, code 1 and code 2.
Specify the address of 1. Also, the address decoder 11
Indicates that the signal generated from the M2 key is decoded, and
The address of AD2 is designated so as to access one code of two data, code 1A and code 2A.

Now, the initial code “ ^* A” is stored in the RAM
13 is stored as code 1, the tail code “#” is stored as code 2 in the RAM 13,
The data is stored in the AM 13 as No. 1 data, and the telephone number “7” is stored.
If “654321” is stored in the RAM 13 as No. 2 data, the user provides a call switching service “ ^* A7” ^.
M1 continuously to send all codes of 654321 # "
Key, M2 key and M1 key can be pressed. This simply means that two keys, the M1 key and M
The operation can be easily performed only by pressing the 2 key. The reason for this is based on the fact that No1 data is empty data. When the M1 key is pressed for the first time, code 1 or No
The function code 1, ie, "
^{* The} switch 19 activates the ROM 121 to send out A ". When the M2 key is pressed, the switch 19
The RAM 13 is reliably operated to send out two data, that is, "7655431".

Next, when the M1 key is pressed, the switch 19 is pressed.
To send code 2 or "#"
Work 2 This method can select another method to perform the same function. Of course, other methods are performed at the user's discretion and are not shown here.

The various methods considered and adopted by the user are determined by the user's convenience, habits, comprehension, and the like.

[0051]

According to the present invention, a RAM 13 for storing data is provided.
And a ROM 12 for storing two function codes respectively
Using 1 and 122, the data and the two function codes have the following benefits by having the same correspondence only at the address lines specified by the address decoder 11 that decodes the dial signal generated from the keypad 10.

The function codes stored in the ROM will not be lost or lost due to the separation between the telephone and the power source. In addition, the function codes are usually determined by the region and are not often changed.
According to the present invention, the trouble of repeatedly inputting the same function code after the power of the telephone is turned off or turned on can be eliminated.
