If the individual number number data is given from a specific key telephone, the total capacity of the individual area is calculated accordingly, and only when the total capacity is less than the specified value corresponding to the capacity of the speed dial memory, the individual number number data is calculated. The capacity of the individual area is allocated according to the area, and the remaining part is allocated as a common area. [Example] Hereinafter, details of the present invention will be explained with reference to figures showing examples. FIG. 1 is a block diagram showing the entire configuration. The main unit (hereinafter referred to as KSU) 1 has external lines 2 ₁ to 1, such as a central office line from a central office or a telephone line from a private branch exchange.

Further, the KSU 1 is provided with a control unit including a processor (hereinafter referred to as CPU) 14 such as a microprocessor, a fixed memory (hereinafter referred to as ROM) 15, and a variable memory (hereinafter referred to as RAM) 16.
The CPU 14 executes the program in the ROM 15,
Control is performed while accessing predetermined data to RAM 16, and LIF 11 ₁ to 11 _o

Control decisions are made according to the operation data from ST4 ₁ to 4 _n , and the LIFs _{11 1} to 11 _o and TSW 12 are controlled, and the control data of ST4 ₁ to 4 _n is controlled by transmitting control data via TIF 13 ₁ to 13 _n . It has become a matter of control. In addition, AC commercial power source used as main power source

In the event of an AC power outage, power is supplied from B18 and backup is performed. In contrast, in ST4 ₁ to ST4 _n , a communication circuit (hereinafter referred to as TKC) 31 is connected to a communication line 32, and a signal line 33 is connected to the CPU 14 and the communication line 32 via a transmission circuit (hereinafter referred to as SRC) 34. ROM1
5. Similar to the RAM 16, but a smaller control unit (hereinafter referred to as CNT) 35 is connected, and a digital display (hereinafter referred to as DGP) and a tone generator in a display circuit (hereinafter referred to as DP) 36, Controls the amplifier and according to control data via SRC34

In response to the operation of each key inside and the operation of the switch HS, operation data indicating these conditions is transmitted via the SRC 34. Note that the SRC 34 has a power separation function, extracts the power supplied from the KSU 1 side via the signal line 33, stabilizes it, and supplies it as a local power V to each part that requires it. Therefore, when off-hook is performed in any ST4, the operation data of this is transferred to the CPU 14.
The key operations in KB37 are also the same, and the CPU 14 outputs TSW1 according to the operation of the outside line key or extension key and the operation of the dial key.

The DP 36 controls the ST4 to emit an extension ring tone, and the call state is established when the other party responds. In addition, incoming calls from external lines 2 ₁ to 2 _o are sent to LIF 11 _{1 to 2} o.
11 _o , and the CPU 14 controls the DP 36 of each ST4 ₁ to 4 _n in response to this to emit an outside call incoming ring tone. Therefore, if any ST4 responds by off-hook, the CPU 1
4 controls the TSW 12 and completes the communication path. Note that, at the same time as these controls, the indicator lights in the KB 37 are also controlled, and the corresponding lights are turned on. In addition, a part of the RAM 16 is used as a speed dial memory, and in response to the general speed dial number _registration operation of ST4 ₁ to 4 _n ,
4 Storing the dial number in the individual area corresponding to _n ,
Then, the dial number is stored in a common area corresponding to all devices, and after registration, this also follows the general speed dialing operation.
The CPU 14 reads the corresponding dial number,
The LIF 11 is controlled to perform dialing using pulse signals or MF signals. However, although the total capacity of the common area and individual areas is fixed, the capacity of each area can be set variably.
The CPU 14 operates as a calculation and allocation means,
It is designed to allocate capacity for each area. FIG. 2 is a flowchart showing the allocation status of each area. When ST4 ₁ , for example, is set as a specific ST and the setting key as an input means provided in the KB 37 is operated, the reception data processing routine by the CPU 14 is started. , the content of the received data is "Setting key operation?" 101, Y (YES), and then a flag, which will be described later, determines "In setting mode?" 102, which is N (NO).
In response to this, a "setting mode flag is set" 103 indicating that the setting mode is in progress, and steps 101 and subsequent steps are repeated via other routines. Next, if step 101 is N, "In setting mode?" 11 is displayed according to the flag in step 103.
1, and if this is Y, the content of the received data is "Individual number number data?" 112 indicating the number of individual speed dial numbers to be assigned to each ST.If this is Y, then "Individual number number x - The data is stored in RAM storage" 113, but in response to N in step 111, "other received data processing" 114 is performed. Next, if steps 101 and 102 both become Y, x and ST
Multiply by several meters to find the total capacity X of the individual area,
"XM?" 122 checks whether or not X is less than the specified value M. If it is N, "error processing" 123 clears x in the RAM 16 and makes it invalid; In this case, after performing "individual area assignment of x for each ST" 131 and "common area assignment of M-X" 132, "set assigned flag" 133 and,
Corresponding to step 103, the “setting mode flag
Therefore, in ST4 ₁ , after operating the setting key, transmit data indicating x using the dial key, etc., and then operating the setting key again, the total capacity M and x of the speed dial memory will be filled. For example, in the case of M=100, x=10, m=4, X=x・m=10×4=40 M−X=100−40=60, and each individual area The capacity is allocated as the number of dial numbers 10, and the capacity of the common area is allocated as the number of dial numbers 60. Fig. 3 is a flowchart showing another embodiment, and as in steps 101 to 103, "Set key operation?" “201 is Y and “In setting mode?” If ``202'' is N, ``set mode flag'' 203 is executed, steps 201 and subsequent steps are repeated via other routines, and step 20 is executed.
If 1 is N and "In setting mode?" 211 is Y,
The content of the received data is “ST number data?” 212,
"Individual number data?" 213 is used to sequentially determine the data, and "other received data processing" 221 is performed in response to N in step 211.
When 2 is Y, “ST number i/RAM storage” 22
2, and in response to Y at step 213, storage is performed using "individual number x memory storage" 223. Next, if steps 201 and 202 each become Y, obtain X as in step 121 by " _n 〓 ⁱ⁼¹ x=X" 231, and obtain "X" as in step 122.
M? ” 232, and if it is N, performs “error processing” 233 in the same way as step 123, and according to Y in step 232, “Each ST
x _i individual area allocation” 241 and “M−X
common area allocation” 242, and step 1
33, 134 “allocated flag set”
243 and “setting mode flag reset” 2
Do 44. Therefore, in ST4 ₁ , after operating the setting key, enter a single digit i using the dial key etc.
By transmitting data indicating 2 digits and 2 digits x and further operating the setting key, each area will be allocated as shown in Fig. 2. For example, M = 100, x ₁ = 10, x ₂ = 15,
^If x ₈ = ₁₀ , _{x 4} = 20, _then
15, the same area of ST4 ₈ is 10, the same area of ST4 ₄ is
20, the common area will be allocated a capacity of 45 dial numbers each. FIG. 4 is a flowchart showing the allocation status when the power is turned on. "Allocated?" 301 is checked according to the flags in steps 133 and 243, and if this is N, "Standard common area allocation" 311 is checked. ,
Then, "standard individual area allocation" 312 is performed, and each value of x and MX is set to the standard capacity. Therefore, the capacity of each area can be determined without performing the setting operations shown in Figures 2 or 3.
Never lose the ability to make speed dial calls. However, if a request arises to increase or decrease the capacity of an individual area or a common area from the standard state, each capacity can be freely changed and set by the operation shown in FIG. 2 or 3, which is extremely convenient in terms of operation. In addition, if the abbreviated numbers used for abbreviated dialing operations for each ST and common similar abbreviated numbers have different numbers in the 10th place, as shown in the table below, the capacity of each area can be allocated variablely. In this case, it is preferable that the abbreviated number does not change.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, each capacity of the individual area corresponding to each ST and the common area corresponding to all devices can be freely set, so that each individual and common speed dial number can be set accordingly. The number can be increased or decreased, which is extremely convenient in terms of operation, and a remarkable effect can be obtained in various key telephone devices.
