Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an electronic switching system with improved operability of a relay stand.

(Prior art) Electronic private branch exchange used in telephone networks. PBXs (hereinafter referred to as electronic exchanges) are constructed using microcomputers, and are increasingly multifunctional and high-performance through software control.

Therefore, electronic exchanges can perform various services in addition to the original telephone exchange operation.

On the other hand, terminal devices such as extension telephones and relay boards connected to such electronic exchanges are also microcomputerized and have become multifunctional and highly intelligent.

The relay stand has a handset, a response switch, an extension key for connecting an extension line, a display lamp (for example, an LED element), and the like. Response switches are provided for each of the six types of calls, extension keys are provided for the extension calls, and display lamps are provided for at least each switch.

When a relay board is connected to an electronic exchange, when a call is received from an outside line to the electronic exchange, the electronic exchange causes the relay stand to send a ringer ringing signal.

As a result, the relay console rings "Rinno J", so when the operator picks up the relay console's handset and presses the response switch to respond, the exchange receives the signal from the response switch and sends the incoming outside line to the relay console. to receive a call. This enables a conversation between the called party and the operator. After confirming the called party's desired destination, the operator looks at the extension key and display lamp corresponding to the called party's extension on the attendant console. Check the current status of that extension.

As a result, if the extension that the other party wants to call is available and the extension key is pressed, the exchange will send a ringer ringing signal to that top line, and the linker will ring on the top line that receives this signal. Ru. When this extension answers, the exchange connects this extension to the relay console to enable a call. In the course of this series of operations, the exchange puts the incoming outside line that was in conversation with the relay stand on hold when the extension key is operated.

In response to the response from the extension, the operator on the relay board side notifies the other party's extension, which has become available for communication, that the call will be handled by the extension. Thereafter, when the operator operates the relay stand to go on-hook, the exchange connects the held incoming outside line and the extension line, allowing both parties to talk.

As mentioned above, the relay console has many key switches, and each key can be assigned a specific function. The assigned specific functions can be managed and executed by software, but the functions assigned to each key are managed by software 1 on the exchange side. In other words, each key on the attendant console is assigned a code that is specific to each key.
When a certain key is operated, the relay stand generates a signal with the assigned code for that key and transmits it to the exchange.

When a certain key is used for connecting extension A, when a code corresponding to that key is received, the exchange side recognizes that the operation is to transfer to extension A, and the exchange side executes the necessary control. On the relay stand side, a logical number is determined for each lamp or ringer, and by transmitting logical number information and on/off information, the lamp or ringer corresponding to the information is driven and controlled.

Therefore, although the relay console can freely assign functions to each key, the functions realized by operating the relay console are left to the exchange side.

Areas such as an electronic exchange control program, fixed data, key assignment data for the relay console, and work area are secured in the memory within the exchange, and the key assignment data for the relay console is used to recognize key operations on the relay console.

Attendant key assignment data means that when the attendant detects a key press, it sends the key code information of the depressed key to the control unit of the electronic exchange. This is a key data table used to determine the type of key pressed from the control unit or its key code information.

Here, if we consider the conventional electronic exchange system, the 16th
It was constructed as shown in the figure. That is, in the figure, 1

Further, the control signal transmission line interface circuit 4 is an interface for transmitting and receiving control signals of the electronic exchange control unit 10, and this interface is connected to the relay board via the line L. Reference numeral 5 denotes a relay console control unit in the relay console 50, which includes a control signal transmission circuit interface circuit 6, a memory 7, a CPU 9, an LED control circuit 10, a key switch control circuit IC voice control circuit 12, and a handset control circuit l3. There is.

The control signal transmission line interface circuit 6 is an interface for exchanging control signals with the electronic exchange control unit 1, and this interface is connected to the electronic exchange control unit 1 via a line L. The CPIJ 9 is a terminal control unit that plays a central role in controlling the relay stand, and is hereinafter referred to as a terminal CPU. Further, the terminal CPU 9 executes operations as a relay console control unit based on the memory 7 configured with ROM and RAM.

The ROM of the memory 2 in the electronic exchange control unit 1 stores an initial program loader (IPL), etc. for reading control programs for the basic functions of the electronic exchange and special services during initialization processing.
The RAM is used for storage of various programs to implement basic functions and special service functions read by the IPL, for storing data necessary for program execution, and as a working area for programs. Ru.

The CPU 3 executes programs stored in the ROM and RAM to realize the function of an electronic exchange. In addition, I
A PL program is an initialization process that is automatically executed when the electronic exchange performs a predetermined reset operation, such as a power-on reset or reset operation, or when a relay console is connected and starts operation. This is a program loading program that performs the process of loading necessary programs from the outside. The terminal CPU 9 of the relay console also has an IPL program, and when the relay console starts operating, it automatically starts processing at the initial stage.

The call type response key 15a is a type of function key, and is a key switch that can respond depending on the type of call.When there are multiple calls received at the same time, the response switch selects the call with the highest priority. It is a key switch that can respond to

FIG. 17 is a diagram showing a memory map in the memory 2 in the electronic exchange control unit 1, in which 2a is an electronic exchange control program area, 2b is a fixed data area, 2c is a relay stand key assignment data area, and 2d is a work area. It is.

Note that the relay key assignment data area 2c in the fixed data area 2b is for transmitting the key number information of the pressed key to the electronic exchange control unit 1 when the relay detects a key press. This is an area that stores a key data table used by the electronic exchange 1 3 exchange control unit 1 to determine the type of key pressed based on the key number information.

FIG. 18 is a diagram showing a memory map in the memory 7 in the relay console control section 5, where 7a is a terminal control program area, 7b is a key assignment data area for the relay console, and 7c is a work area. Note that the key assignment data area 7b is an area in which the relay console control unit 5 transmits the key number information of the pressed key to the electronic exchange control unit 1 when a key press is detected.
This is an area that stores data indicating the key number to be transmitted and its type.

Next, the operation of the conventional system will be explained with reference to the operation transition diagram in FIG. 19 and the flowcharts in FIGS. 20 and 21. When the relay console control unit 5 receives power supply from the stopped state, the terminal CPU 9 sends the IPL program to the line L via the transmission path interface circuit 6 (FIG. 19 (T3)
). When this "operation start report" signal 14- is received via the control signal transmission line interface circuit 4 (T4), the CPU 3 of the electronic exchange control section i issues a "terminal processing start" message to the relay console control section 5. The signal is sent (FIG. 19 (T5)) and the process moves to the exchange (FIG. 19 (T8)). The "terminal processing start" signal is sent via the control signal transmission line interface circuit 4, line L, and control signal transmission line interface circuit 6, and the relay stand control unit 5 that receives this signal starts terminal processing (19th Figure (T7)
).

Next, to explain the incoming call response processing operation of the relay board and the electronic exchange, the electronic exchange control unit 1 makes a "ringing sound" when there is an incoming call.
By sending a signal to the relay console control unit 5, a call is received at the relay console.

On the other hand, upon receiving the "ring ringing" signal, the relay stand control unit 5 controls the speaker 18 to emit a ringing tone via the audio control circuit 9. Upon hearing this, the operator at the relay console presses the response switch on the relay console to answer the incoming call. Then, this suisochi's work is transmitted to the terminal CPU 9 via the key switch control circuit 1l, and the terminal C
PU 9 is a response switch] 5? A press is detected (S1). Upon this detection, the terminal CPU 9 activates the terminal control program area 7a of the memory 7.
The number and type of the pressed key are determined by referring to the key assignment data area 7b (S2).If this antagonist is the call Φ type response key 15 (S3), then the pressed call @ type response key It is determined via the LED control circuit 10 whether or not the 15 LEDs 14 are lit (S4).

That is, call type response or fib self. 1,1■14 When the light is on, the assigned function is active, and when the light is off, the function is stopped, so this is controlled by the terminal CPU 9. L according to control
ED control circuit {0 controls lighting. Therefore, the L
If ED 1.4 is not lit, it is determined that the key press is invalid, and the process ends without doing anything (S7). The LED
If 14 is lit, it is determined that pressing the key immediately is valid,
At the same time as transmitting the "key number" signal to the electronic exchange control unit 1, the voice control circuit]2 is operated, and the speaker 18 is activated.
A key confirmation sound is emitted (S5S8).

If the pressed key is not the call type response key lh, pressing the key is always valid, so the electronic exchange control unit 1 sends out a "key number" signal and at the same time activates the voice control circuit l2. , a key confirmation sound is emitted from the speaker 18 (S5, SS).

On the other hand, when the electronic exchange control unit 1 receives the "key number" signal (S21), it refers to the key data table in the attendant key assignment data area 2c in the memory 2 and determines what key it is (S22). ), enters the process of that key (S23
). For example, if there is a response to an incoming call, a ``stop ringer'' signal is immediately sent to the relay console control section 5, and at the same time, a ``call start'' signal is sent to the relay console control section 5, and the process proceeds to call processing.

When the relay stand control unit 4 receives the "stop ringer" signal, it operates the audio control circuit 9 to stop the ringer.

Further, by receiving the "call start" signal, the voice control circuit 9 is operated to perform a call processing operation, and the call processing is performed and the call is started.

In this way, when responding to an incoming call and connecting to the desired extension of the other party, the user operates the key corresponding to the extension. As a result, the exchange calls 17 lines corresponding to the corresponding key, and when the other party answers, the operator at the relay stand can resume the call by pressing the key to exit the call.

By the way, in conventional devices, depending on the type of key, special processing may be required on the terminal side when the key is pressed, and for this reason, key assignments had to be fixed. Therefore, within the system, the key assignments are fixed, and if the key assignments are to be changed in accordance with the user's request to make it easier for the user to use, the programs in the memories 2 and 7 must be changed.

(Problem to be Solved by the Invention) In an electronic exchange in which a relay stand is connected as a terminal in this way, when various keys of the relay stand are operated, the code information of the key is sent to the electronic exchange side. The electronic exchange side performs control based on the received key code, such as executing the function assigned to the operated key, receiving it as data, and performing an exchange operation.

18 Therefore, when a key on the relay console is pressed, key recognition processing is performed on both the relay console side and the electronic exchange side in order to know the function of that key. In conventional devices, depending on the type of key, special processing may be required on the terminal side when the key is pressed, and for this reason, key assignments had to be fixed. Therefore, the key assignments are fixed within the system, and if the user wishes to change the key assignments to make it easier for the user to use, it is necessary to change the memory programs on the relay stand side and the exchange side.

For this reason, the flexibility of software control is not utilized at all, and there is a drawback that there is extremely little freedom in changing the key function assignments.

Upon receiving this, the terminal stores it in the second storage means, and also sends the stored information corresponding to the expansion unit to the expansion unit. This is stored in the first storage means in the expansion unit. Thereafter, when any one of the multiple keys of the expansion unit is operated, the key notification assigned to that key is read from the first storage means and sent to the terminal, and the terminal Send this to the exchange.

According to this, if the exchange stores the assigned key information and function information for each key on the relay console in advance, the stored assigned key information will be sent from the exchange when the relay console is connected to the exchange. , this is memorized at the relay stand. When a key on the relay console is operated, the relay console obtains the assigned key information of the operated key based on the information stored in the memory 70,
Since this is sent to the exchange, the exchange learns the function corresponding to this assigned key information by referring to the assigned key information and function information for each key on the relay stand that has been stored in advance in the memory 20, and then learns the function. Execute. This kind of operation becomes possible.

Next, the operation of this system having the above configuration will be explained with reference to the operation transition diagram shown in FIG. Relay console control unit 5 that was in a stopped state
When power is supplied to a and it starts booting, the terminal CPU
9 starts the IPL (Initial Program Load) program (Fig. 5 38) and sends it to the line L via the base circuit 6 (Fig. 5 (Tl3)
)).

The contents of the "operation start request" signal include, for example, the code, the number of function keys, the odd-sized rice selection, and the like. This “operation start report” signal is sent to the control signal transmission line interface circuit 4.
(T14), the CPU 3 of the electronic exchange control section 1a stores the memory 20 in advance for the relay control section 5a.
Sends the "key assignment data" prepared in
(TI5)), the relay console control unit 5a receives this and enters the key assignment τ in the work area 70c in the memory 70.
j data area 70b (Fig. 5 (T1B))
.

When this is finished, the relay console control section 5a will control the electronic exchange control section 1.
Sentence to a. JL sends out a "Key assignment data reception report" signal (Figure 4 (Tl7)). Electronic exchange control section 1a
When it receives this "key assignment data reception report" signal, it sends a "terminal processing start" signal to the relay stand (see Figure 5).
T.I. 8)), the process moves to the exchange processing (FIG. 5, 39 (T19)). The "terminal processing star 1." signal is sent via the control signal transmission line interface circuit 4, line L, and control signal transmission line interface circuit 6, and the relay stand control unit 5a that receives this signal starts terminal processing ( Figure 5 (
'I'20)).

The above is a general description of the operation, and the details of the operation can be explained in more detail as shown in FIG. 6.

When a terminal is connected, an operating electronic exchange (hereinafter referred to as PBX) side recognizes that the terminal has been connected, and thereafter starts service for the terminal. To this end, the PBX side checks whether TI3 (r operation start report) signal is received between normal operations (ST
I, ST2).

If T]3 is not received, the process moves to ST8 and normal processing operations are performed again. In ST2, if TI3 is received, the process moves to Si'3 and TI5 (key assignment data) is transmitted. After that, T17 (r key assignment 1 data reception report)
Waits for reception of Tl7 signal), but if Tl7 is not received, ST
Step 7 starts the timer and waits for reception of T17 until the specified time has elapsed.

40 When the timer expires, the process moves to ST8 and normal processing operations are performed again.

T.I. 7 is received, the connection of the relay console is registered in the memory 20 in the PBX (ST5). 8
After sending the , the normal processing operation starts again (ST8)
.

Attendant stand (ATT BiNl) ANT. (hereinafter referred to as ATT)
The operation is as follows. When the power is turned on to the ATT which has been in a resting state, the ATT is activated at this point.

To turn on the power, if the ATT has a power switch,
This is when the modular connector 44 and the line L are connected and the switch is turned on. Also, if the ATT does not have a power switch, the modular connector 44
This is when the line L and line L are connected.

When the power is turned on, the power supply 42 converts the DC voltage supplied from the PBX side via the line L into the voltage required within the ATT and supplies it to each element within the ATT, so the ATT starts up. Become (STII).

When the ATT is activated, the terminal CPU 9 of the ATT 41 initializes itself (STl2), and then sends out Tl3 (r operation start report" signal) (ST43). and,]
Waiting for reception of ゛15 (“Key allocation i/j data”) (
STI4).

When TI5 is received, terminal CPU 9 stores it in memory 70. Next, it sends TI7 (r key assignment {1 data reception report'' signal) (STIB), waits for reception of T18 (terminal processing start signal), and enters normal processing.

If TI8 cannot be received, ATT after a predetermined time has elapsed.
is automatically reset and restarts from initialization operation.

This will enable the PBX to execute the process of engraving on the relay console, and the relay console will be able to use its function as a relay console.

Next, the incoming call response processing operations of the relay board and the electronic exchange will be explained. When the electronic exchange control unit 1a receives a call, it rings a ringer.
By sending a signal to the relay console controller 5a, a call is received at the relay console.

On the other hand, when the relay stand control unit 5a receives the "ring ringing" signal, it controls the speaker 18 to emit a ringing tone via the audio control circuit 9.

42 Hearing this, the attendant operator presses the answer switch or call type response key 15a on the attendant stand to answer the incoming call.
Press. The operations of these key switches are transmitted to the terminal CPU 9 via the key switch control circuit {1,
PU 9 detects pressing of a key switch.

Upon this detection, the terminal CPU 9 executes the key assignment data area 70b in the terminal control program area 70a of the memory 70.
to find the code and type of the key pressed. If it is the call type response key 15a, the terminal CPU
9 is the LED of the pressed call type response key 15a; 14
Control the lighting of a.

The call type response key is a key switch that can respond depending on the type of call, and the response switch is a key switch that can always respond to the call with the highest priority when calls arrive at the same time.

That is, the call type response key 15a has its own LED 14.
The terminal CPU 9 controls the assigned function so that when it is turned on, the assigned function is activated, and the function is stopped when it is turned off.According to this control 43, the LED control circuit {0 is turned on. It's in control.

Therefore, the LED I. If 4a is not lit, the key press is invalid, and the terminal CPU 9 ends without doing anything. If the LED 14a is lit, the key press is valid, and the terminal CP is activated by pressing the key.
The U 9 sends a "key code" signal for the key to the electronic exchange control section 1a, and at the same time operates the voice control circuit 12, causing the speaker 18 to emit a key confirmation sound.

If the pressed key is not the call type response key 15a, the key press is always valid, so when the terminal CPU 9 sends the "key code" signal of the pressed key to the electronic exchange control section 1a, ! i operates the audio control circuit {2, and the speaker 18 emits a key confirmation sound.

On the other hand, when the electronic exchange control unit 1a receives the "key code" signal, the CPU 3 refers to the key data table in the attendant key assignment data area 20c in the memory 20, determines what key it is, and determines the key code. Start key processing.

For example, if it is a response switch 44 for a normal response to an incoming call, it will immediately send a "stop ringer" signal to the relay console controller 5a, and at the same time, the relay console controller 5a
Then, it sends out a "call start" signal and moves on to call processing. When the relay stand control unit 5a receives the "stop ringer" signal, it operates the audio control circuit 9 to stop the ringer. Further, by receiving the "call start" signal, the voice control circuit 9 is operated to perform a call processing operation, and the call processing is performed and the call is started.

In this way, when responding to an incoming call and connecting to the desired extension of the other party, the user operates the key corresponding to the extension. As a result, the exchange calls the extension line corresponding to the key, and when the other party answers, the operator at the relay console presses a key to disconnect from the call, and the electronic exchange relays the line of the called party who answered at the relay console. The machine transfers the call to the extension and connects it to make the call possible.

The above-described control within the system is realized by the CPU 3 on the PBX side and the CPU 9 on the relay stand side executing control programs, respectively.

45 In conventional devices, the key assignments for response keys and function keys are fixed, and it is not possible to assign key functions to desired keys so as to create a key arrangement that is easy for the user to use.

In this system, the key assignment is performed from the exchange side when the relay console is initialized, and is stored and set in the memory of the relay console, so the system can have flexibility in key assignment. Therefore, in order to change the key assignment to make it easier for the user according to the user's request, it is only necessary to change the assignment data on the exchange side, and there is no need to change the terminal program including the relay console side as in the past. do not.

Next, a modification of the present invention will be shown. The configuration of FIG. 7 shows an example of a system in which an additional keyboard can be connected to a relay stand.

The relay console control section 5b shown in FIG. 7 is basically the same as the embodiment shown in FIG. 1, and has a 1/0 interface 71 and a , this one
A connector 72 connected to a /0 interface 71 is provided. I/O interface 46 interface 7] is connected to CI) U9, and
The CPU 9 is in charge of necessary control as a relay stand, and this CPU 9 can search the output signal of the 1/0 interface 7l and monitor the status, as well as code the output signal of the 1/0 interface 71. The I/O interface 7 has a function to send the data to the electronic exchange control unit 1a, and a function to send out designation information and on/off information specific to each lamp, which is assigned to each lamp of the terminal device connected to the I/O interface 7. It is shown.

The additional keyboard 81 includes a connection cable 82, an I/O interface 83, a controller 84, a RAM 85, and a
The OM 86 has a plurality of key switches 87a to 87n1 and display lamps (eg, LEDs) 88a to 88n provided corresponding to each of the key switches 87a to 87n. The I/O interface 83 is for exchanging signals with the outside, and this I/O interface 83 connects to the connector 72 of the relay console control unit 5b via the connection cable 82.
connected to.

The controller 1 roller 84 is in charge of controlling the additional keyboard +;
7 External signal exchange and each operated key switch 87a
87n, on/off control of the display lamps 88a to 88n, etc. can be performed.

The controller 84 performs necessary control according to the control program stored in the ROM 8B, and the RAM 85 is used as a working area and temporary storage of data necessary for the control.

The additional keyboard (additional unit l-) 81 is configured to be supplied via the connecting cable 82 by connecting the connecting cable 82 to the connector 72 of the relay console control section 5b. Therefore, in the relay console control unit 5b, the connector 72
The configuration is such that it can supply power to the terminal.

When the additional keyboard 81 receives power supply via the connection cable 82, the power is turned on and the IPL (Initia
l Program Load) Star 1・i.e.
A cold start is performed, initialization processing is performed, and then a setup operation start signal is sent to the I/O interface 83. Next, it waits for allocation data, and the 1/0 interface 8
48 When receiving the interrupt data from the outside via 3, it is sent to l? Saved at AM 85 and another 1/0
When a star 1 signal is received from the outside via the interface 83, each operated key switch 87a to 87n is recognized and the code of the recognized key switch is input to I? A [8
Based on the allocation data saved in step 5, on/off control of display lamps 88a to 88n corresponding to the operated key switches is performed. Such a control program is R
Stored in OMH.

On the expansion keyboard 81 side, each display lamp 88a to 88n
Specific designation information is defined in advance, and the exchange side transmits the necessary control content in the form of designation information and on/off information to the relay board by executing this information. Thereby, the relay console recognizes from the received information that it is a control command for the additional keyboard 81, and transfers the received designation information to the additional keyboard 81 side.

FIG. 8 is an external view of a relay stand to which one keyboard 8I can be connected, and is laid out as shown in the figure.

FIG. 12 is a block diagram 49 showing the functional configuration of the terminal CPU 9 in the relay console control section 5b broken down into elements, and FIG. FIG. 2 is a block diagram showing the configuration broken down into elements.

As shown in FIG. 12, when initializing the relay console, that is, after the terminal CPU 9 performs an initialization operation, the terminal CPU 9 is placed in a standby state in which it accepts key information settings for each key on the relay console. When the key information to be set is received from the exchange, the first control function section 9a completes the setting reception by storing it in the memory 70, and the setting reception by the beat 1 control function section 9a is completed. After that, when the extension unit 81 is connected to the relay stand, the second control function section 9 sends the key information to be set for the J So installation unit to the connected J So installation unit 8l.
l), when any of the plurality of keys on the relay console is operated, the assigned key of the operated key {=I key information is stored in the memory 7
It is composed of a third control function unit 9C that causes the stored information of 0 to be sent to the exchanger by the buttocks, and when there is allocation key information obtained from the expansion unit 8{, this allocation key information is sent to the exchanger. .

50 The controller 84 in the expansion unit 81 is the 13th
As shown in the figure, the key information (key code data) to be set sent from the relay console is received and stored in the RAM 8.
When any of the plurality of keys in the expansion unit 81 is operated after the storage control function unit 84a and the storage control function unit 84a have finished controlling the storage of key information, this is detected and the operation is performed. Is the assigned key information of the assigned key? A key information transmission control function unit 84b that obtains the information stored in the AM 85 and transmits it to the relay stand side via the I/O 83.
and a lamp control function section 84c that controls on/off the corresponding LED determined by the LED drive control information among the LEDs 88a to 88n based on the LED drive control information sent from the relay stand side.

In the case of the system shown in FIG. 7, the CPU 3 of the exchange control unit 1a
As shown in FIG. 14, there is a registration control function unit 3a that registers in the memory 20 key information to be assigned to each key of the terminal including the relay stand and the expansion unit, and functions for each key information.
When the terminal device is connected, it is checked whether the terminal device is connected or not, and when it is recognized that the terminal device is connected, the registered key information to be assigned to each key set in advance for the terminal device is read out from the memory 20 and transferred to the terminal device. a transfer control function unit 3b that provides key information from a terminal, and a processing control function that, upon obtaining key information from a terminal, learns the function assigned to the key information from the information of functions for each key information registered in the memory 20, and executes the function. The structure includes a section 3C.

According to this, if the exchange stores the assigned key information and function information for each key of the terminal and expansion unit in advance, the stored assigned key information will be transferred from the exchange when the terminal is connected to the exchange. This is sent to the terminal and stored in the terminal.

When a key on a terminal is operated, the terminal obtains the assigned key information for the operated key based on the information stored in the terminal and sends this to the exchange, so the exchange corresponds to this assigned key information. The function is known by referring to the assignment key information and function information for each key of the terminal stored in advance in the exchange, and the function is executed.

On the other hand, when the extension unit is connected to the terminal, the terminal 52 transmits the stored assignment key information for the extension unit from the terminal to the extension unit. The expansion unit then stores this sent allocation key information. When a key on the expansion unit is operated, the expansion unit extracts the assigned key information for the operated key based on its own memory information and sends it to the terminal, which then transfers it to the exchange.

The exchange will perform the function corresponding to the received assigned key information.
The user refers to and learns the assigned key information and function information for each key of the terminal stored in advance in the exchange, and executes the function. This kind of operation becomes possible.

Next, the operation of this system having the above configuration will be explained.

The memory 20 of the electronic exchange control unit ta stores in advance the programs and data necessary for controlling the relay when the relay is connected, including when an extension unit is connected to the relay. When the electronic exchange control section 1a recognizes that the stand is connected to the electronic exchange, it reads out the data of the relay stand and extension unit stored in the memory 20 and sends it to the relay stand. Here, the data also includes information on the assignment of each key switch, etc. to the expansion unit as key assignment data.

The extension unit is now connected to the relay stand control section 5b which is in a stopped state. Then, when power is supplied to the relay stand control unit 5b that has been in a stopped state and it starts to start up, the terminal CPU
9 sends the IPL program to the line L via the control signal transmission line interface circuit 6 in order to give an operation start report signal to the star 1 and electronic exchange control section 1a. The contents of the operation start report signal include, for example, a code,
This includes the number of function keys, terminal type, etc.

The CPυ3 of the electronic exchange control unit 1a is configured to periodically check whether such an operation start report signal has been sent. Therefore, the CP of the electronic exchange control section 1a
When the U 3 receives the "operation start report" via the control signal transmission path interface circuit 4, it causes the relay console control unit 5b to send key assignment data prepared in advance in the memory 20.

The relay console control section 5b receives this and is controlled by the CPU 9 as follows. The relay console control unit 5b stores this received data in the key division f;j data area 70b in the work area 70c in the memory 70.

Once this is finished, the relay console control section 5b will switch to the Shiso unit 81.
Checks whether a setting operation start signal has been received from the electronic exchange control section 1a, and if so, sends an operation change signal to the electronic exchange control section 1a.
The expansion unit-related portion of the allocation data in the memory 70 is sent to the expansion unit.

Exchange of data, etc. between the relay console control unit 5b and the expansion unit 81 is performed through 1/0 (input/output interface) 71.
It goes through 83. After that, relay stand control unit 51)
causes the electronic exchange control section 1a to send a key assignment data reception report signal. When the electronic exchange control unit 1a receives the operation change signal, it changes the function to operate as if the extension unit 81 is connected to the relay stand,
When receiving the key assignment data reception report signal, it sends a terminal processing start signal to the relay stand side and moves on to exchange processing.

The terminal processing start signal is sent through the control signal transmission line interface circuit 4, the line L, the control signal transmission line interface 55, and the loop 1 of the interface circuit 6, and upon receiving this signal, the relay stand control unit 5b starts terminal processing. When the power is turned on, the controller 84 of the 19-set unit 81 operates, sends a setting operation start signal to the relay console control section 5b, and sends the allocation data received from the relay console control section 5b to the RAM 8.
5, the expansion unit 81 becomes ready to operate.

The above is a general description of the operation, but a more detailed explanation of the operation is as shown in FIG. 9. When a terminal is connected to an operating PBX, the PBX recognizes that the terminal has been connected, and thereafter starts service for that terminal.

To this end, the PBX side (electronic exchange control unit Ia side) checks whether T13 (operation start report signal) is received during normal operations (ST]., ST2).

If T13 is not received, the PBX side moves to ST8 and performs normal processing operations again. In ST2, 1
If ``13'' is received, the PBX side moves to Si'3,
Transmit T15 (key allocation fmaj data: also includes allocation {j number information etc. for specifying each LED, speaker, etc.) 56.

The transmission contents of T15 here include ATT's (key assignment data) as well as assignment numbers ↑+'l information for specifying each key switch and each LED of the expansion unit, etc., and these information. connect the maintenance terminal to the PBX,
As a result, it is assumed that an input is sent to the PBX in advance.

In the previous embodiment shown in FIG.
We wait for the reception of I7 (key assignment data reception report signal), but in the example shown in Figure 9, since an additional keyboard can be connected to the relay stand, steps ST31 and ST32, which are the operation change signal check routine, are newly added. It has been added.

Therefore, when ST3 is executed, the PBX receives the operation change signal T2.
3 is received (ST31), and if not, it is checked whether T17 (key assignment data reception report signal) is received (ST4). As a result of the check in ST3L, if the operation change signal T23 is received, the operation change process is performed (ST32) and the execution of ST4 begins.

The operation change process is the setting of whether or not to perform 57 control related to the state unit, and if T23 is not received, it is recognized that only the relay stand (ATT) is connected and control is performed within that range. When T23 is received, it is recognized that the ATT with extension unit l-{=I is connected, and the setting is made to control the ATT side including the extension unit.

In ST4, the presence or absence of reception of T17 is checked,
As a result, if Tl7 is not received, move to s]゛7,
Tl7 until the predetermined time elapses after starting the timer.
Wait for reception.

When the timer is up, move to sT8 and r
After registering ``No ATT connection'' (111), normal processing operations are performed. T.I. If you receive 7, press A.
The fact that the TT has been connected is registered in the memory 20 in the PBX (ST5), and after sending out T18, the normal processing operation begins again (ST8).

The operation on the ATT side is as follows. A was in a stopped state
When the power of the TT (relay control section 5b in the figure) is turned on, the ATT is activated for the first time at this point.

5 8 To turn on the power, if the ATT has a power switch,
This is when the modular connector 44 and the line L are connected and the switch is turned on. Also, if the ATT does not have a power switch, the modular connector 44
This is when the line L and line L are connected.

When the power is turned on, the power supply 42 converts the DC voltage supplied from the PBX side via the line L into the voltage required within the ATT and supplies it to each element within the ATT, so the ATT cannot be started. Become (STII).

When the ATT is activated, the terminal CPυ9 of the ATT initializes itself (STII), and then sends out T13 (operation start report signal) (ST13). And Tl5 (
The device waits for reception of key assignment data (ST14). Tl
5 is received, the terminal CPυ9 stores it in the memory 70 (STI5).

In the previous embodiment shown in FIG. 6, after this, the ATT side sends T17 (key assignment data reception report signal) (ST
IB), waiting for reception of T18 (terminal processing start signal) before entering normal processing. However, in the example shown in FIG. 59, since it is possible to connect an additional unit (such as a J-equipped keyboard) to the relay stand, processing routines ST41 to ST45 for this purpose are newly provided.

That is, STI. When the process in step 5 is completed, it next checks whether or not a setting start signal has been received from the first unit (ST41), and if not, it sends T17 (key assignment data reception report signal) (STI6). Waiting for reception of T18 (terminal processing start signal), normal processing begins.

In ST4 1, if a setting start signal is received, an operation change signal is sent to the PBX side (ST42), and then allocation data is sent to the expansion unit (ST4).
3), sends Tl7 (key assignment data reception report signal) (STIG) and waits for reception of T18 (terminal processing start signal). When the ATT receives Tl8 sent from the PBX, it sends a start signal to the expansion unit (ST44), and then begins normal processing.

Of course, it is also possible to execute the check in ST41 every time g9 and execute the processing from ST41 onwards at any time when the extension unit is connected, so that the extension unit can be used at a desired time.

On the expansion unit side, by connecting the cable to ATT, the power is turned on, IPL starts, and after initialization, a setting operation start signal is generated (ST51,
ST52).

Next, the expansion unit side waits to receive allocation data from the ATT side, and when it receives the allocation data, it saves this data in the memory (RAM 85). When the expansion unit side receives a start signal from the ATT side, it becomes ready to start operation (ST54), and when a key switch on the expansion unit is operated, the code corresponding to the key switch is assigned to the assignment stored in the memory. Based on the data, it sends it to the ATT side or performs on/off drive control operations for the corresponding LED based on the on/off signal for the specified LED sent from the ATT side.

This enables the PBX to execute processing for the relay console, and the relay console can use its function as a relay console.

61 Next, the incoming call response processing operations of the relay board and the electronic exchange will be explained. When the electronic exchange control unit 1a receives a call, it sends a ringer ringing signal to the relay console control unit 5b, thereby causing the call to arrive at the relay console.

On the other hand, upon receiving the ringer ringing signal, the relay stand control unit 5b controls the speaker 18 to emit a ringing tone via the audio control circuit 9. Hearing this, the operator at the relay console presses the answer switch or call type response key on the relay console in order to respond to the incoming call.

This key switch operation is transmitted to the terminal CPU 9 via the key switch control circuit 11, and the terminal CPU 9 detects the depression of the key switch.

As a result of this detection, the terminal CPtJ 9 updates the key assignment data area 70 in the terminal control program area 70a of the memory 70.
Refer to b and find the number and type of the pressed key. If it is the call type response key 15a, the terminal CPU
9 is the LED of the pressed call type response key 15a; 14
Control the lighting of a.

That is, the call type response key 15a is set to its own L E D1.
When the LED 4a is turned on, the assigned function 62 is active, and when the lamp is turned off, the function is stopped.According to this control, the LED control circuit 10 controls the lighting. are doing.

Therefore, if the LED 14a is not lit, the key press is invalid, and the terminal CPU 9 ends without doing anything.

If the relevant LEI) +4a is lit, the key press is valid, and the terminal CPU 9 sends a "key code" signal for that key to the electronic exchange control section 1a, and at the same time activates the voice control circuit 12. The key confirmation sound is emitted from the speaker 18. If the pressed key is not the call type response key 15a, the key press is always valid, so the terminal CPU 9 sends the "key code" signal of the pressed key J111 to the electronic exchange control section 1a, and at the same time The voice control circuit 12 is operated to cause the speaker 18 to emit a key confirmation sound.

On the other hand, when the electronic exchange control unit 1a receives the key code signal, it refers to the key data table in the attendant key assignment data area 20c in the memory 20, determines what key it is, and processes the key. enter. For example, if the response key for an incoming call is call 7: (, then a "stop ringer" signal is immediately sent to the attendant controller 5b, and at the same time a "start call" signal is sent to the attendant controller 5b, and the call is made. Move on to processing.

When the relay stand control unit 5b receives the "stop ringer" signal, it operates the audio control circuit 9 to stop the ringer. Further, by receiving the "call start" signal, the voice control circuit 9 is operated to perform a call processing operation, and the call processing is performed and the call is started.

In this way, when responding to an incoming call and connecting to the desired extension of the other party, the user operates the key corresponding to the extension. As a result, the exchange calls the extension line corresponding to the key, and when the other party answers, the operator at the relay console presses a key to disconnect from the call, and the electronic exchange relays the line of the called party who answered at the relay console. The machine transfers the call to the extension and connects it to make the call possible. When the extension unit 81 is connected, the extension assigned by each key switch of this extension unit 81 and the code corresponding to that key switch are displayed on the relay stand when the extended function 64 key is operated. and then further sent from the repeater to the exchange.

On the exchange side, based on the code sent from the relay board,
Sends a ringer signal to the target extension, transfers an incoming call, or performs a function according to the defined function content of the function key. The on/off control of the LED of the expansion unit 81 is as follows:
The relay board judges the designation information and on/off information unique to each LED sent from the exchange side as information for the extension unit 81, and transfers it to the extension unit 81.・Roller 84 is RAM 85
target LED based on the allocation data stored in
on/off control.

The following is an explanation of another embodiment of the present invention, and the above-mentioned control is performed by the CPU 3 on the PBX side and the CPU 3 on the ATT side.
9, and in the expansion unit 81, the controller 84
However, it is implemented based on the control program.

In the embodiment shown in FIG. 9, when the ATT is connected to the exchange (PBX) 65, an ATT operation start report is sent to the PBX (ST2), and when an extension unit is connected to the ATT side, this connection is Although the operation change signal is sent (ST42) to report the above information, it is also possible to do this all at once.

An example of this is shown in FIG. 15 as flowchart 1. This figure summarizes the main points of the operation on the ATT side, and a step-by-step explanation is as follows.

When the ATT, which has been in a stopped state, is powered on, the ATT starts up for the first time at this point. Power h; (ON is ATT
If there is a power switch on the
4 and the line L are connected and the switch is turned on, or when the ATT does not have a power switch, the modular connector 44 and the line L are connected.

When the power is turned on, the power supply 42 converts the DC voltage supplied from the PBX side via the line L into the voltage required within the ATT and supplies it to each element within the ATT, so the ATT cannot be started. Become (STIR).

When ATT is started, ATT's terminal CPIJ 9 is 6
6 Initializes itself and then waits to receive the WAKE-UP signal from the expansion unit (ST4)
1). The wake-up signal indicates that the extension unit is connected to the ATT and is ready for operation.
This is a signal to notify the TT.

This signal corresponds to the setting operation start signal in FIG. 9, and the setting operation start signal may be used as is.

The wait for reception of this wake-up signal continues for a predetermined period of time after the ATT is activated, until this signal is received. If a wake-up signal is received within this time, the ATT CPU registers "extension unit present" in the memory (ST82), and generates a wake-up signal with the information "extension unit present" as a wake-up signal from the ATT to the PBX. Send (S
T13b).

On the other hand, if the wake-up signal from the expansion unit is not received by the time the wake-up signal reception wait time elapses in the STI31, the ATT CPU will write "
67 (STG3), and transmits a wake-up signal having information of "No J-installed unit" as a wake-up signal from the ATT to the PBX (ST13a).

Next, it waits for key assignment i/j data reception (ST14).
If the key allocation (=1 data) is received, the ATT CPU stores it in the memory (STl5), and then the ATT CPU
U checks the presence or absence of the extension unit l based on the registration information of the presence or absence of the extension unit stored in the memory (ST[i4
). As a result, if there is no expansion unit, a key assignment data reception report is sent to the PBx (STI8), as in the case of FIG.
18.

If the result of checking the presence or absence of an extension unit (STG4) is "Extension unit I/Yes", transmit key assignment data for the extension unit (ST43), and wait for a predetermined period of time for a reception report of key assignment information from the extension unit (STG4). STB5.9T
BG), upon receiving this reception report, transmit the reception report of the key assignment data to the PBX as in the case of Figure 9 (S
Tl[i), hereinafter referred to as STl7, ST44. S'rl
Follow ll.

6 8 If the reception report of key assignment information is not received from the expansion unit within a predetermined time, it moves to ST (i3) and displays the ATT CP.
U registers ``No expansion unit j'' in the memory (STB3
), the ATT transmits a wake-up signal having information indicating "no expansion unit" as a wake-up signal from the ATT to the PBX (ST13a). After that, follow the steps after ST14 in order.

From the above explanation, the following becomes clear.

In conventional devices, the answer switches, call type answer keys, and function keys have fixed key assignments, making it impossible to assign key functions to desired keys in order to create a key arrangement that is easy for the user to use. It was also not possible to add a key switch.

In contrast, in this system, relay boards and expansion units have as a basic function the function of sending out the code of the operated key based on key assignment information, and lamps and buzzers have the function of sending out the code of the operated key based on the key assignment information. In addition to receiving the on/off information, the relay board and the extension unit control the relay board, and when the extension unit is connected, the relay board notifies the switch side, and the switch board puts it under control based on the received information. The system recognizes the object, gives key code assignment information to the controlled object, and executes control operations based on the key code assignment information. Then, when initializing the relay console, key assignment information for the relay console and expansion units is given from the exchange side, and the necessary information for each (attendant console and expansion unit) is stored and configured in each memory, so the system This allows flexibility in key assignments.

Therefore, if you want to change the key assignment or add more keys to make it easier for the user according to your request, you only need to change the assignment data on the exchange side or change the processing program. As such, there is no need to change the terminal programs, including those on the relay stand side.

Therefore, according to the present invention, if information for key setting of the communication terminal connected to the exchange is prepared on the exchange side, it is possible to set the function of the key of the communication terminal during initialization of the communication terminal. 70 matches the user's needs (by simply providing the terminal's key allocation {=I information on the exchange side, it will be possible to arrange the function keys in a way that is easy to use according to the usage pattern of the user) .

Therefore, according to this author, it is possible to easily change the assignment of function keys on communication terminals such as relay stations, and to make it possible to customize the function keys according to the usage pattern of the user. Exchange systems can be provided.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can of course be modified and applied as appropriate without changing the gist of the invention. For example, in the above embodiments, as a terminal For example, a relay stand or other terminal-C can be used.

In addition, in this example, by sending the key assignment data to the relay console, the relay console holds this key assignment data f and j, and the key assignment data determined based on the key assignment data is determined by the key operation on the relay console. The key code was sent from the relay stand to the switchboard. Then, the exchanger executes the exchange control operation determined by 71 on the received key code, and sends the I/O corresponding to the previously operated key to the relay stand. E Point D
The system sends control commands to turn the lights on or off.

In response to this control command, the relay stand side performs on/off operations of the corresponding LEDs.

In this case, the switching equipment must also send LED control commands to the relay stand, which increases the load on the switching equipment. Therefore, during busy times when calls are frequently being made and received, the switching equipment may experience problems such as slowing down its original switching operations, so it is desirable to reduce the load on the switching equipment as much as possible.

To do this, the relay console side must send the key code of the operated key to the exchange, and the relay console side must execute the LE code that must be executed after that key operation.
For specific controls such as on/off of D, etc. that can only be performed on the relay side (of course, this is limited to control operations that can be carried out voluntarily on the relay side), do not wait for commands from the exchange side72 Therefore, it is better to have the measures implemented on the relay stand side.

For example, if pressing a certain key involves a fixed action such as turning on the LED of that key, the relay console's CPU should have a program that causes the CPU to perform such action. And it can be easily achieved.

In addition, since this is a matter of course, when the switch receives a key code from the relay console, the relay console only performs operations such as turning on and off the LED, which the relay console itself has to do automatically. As for the specific control described above, it is assumed that the exchange does not send control commands. As a result, the burden of control is placed on the relay stand side, and the control load on the exchange can be reduced, and delays in operation during congestion can be reduced.

[Effects of the Invention] Second, as described above, according to the present invention, if information for setting keys of communication terminals is prepared on the exchange side, the keys of communication terminals can be set at initialization Bl of communication terminals. Function settings can be made, and by simply preparing the key assignment information of the communication terminal that matches the user's needs on the exchange side, the function keys can be arranged for ease of use according to the user's usage pattern. It becomes like this.

Therefore, according to the present invention, it is possible to easily change the function keys of a communication terminal such as a relay stand, etc., thereby providing operability that enables customization according to the usage pattern of the user. can provide a good electronic exchange system.
