03), the data is subjected to diphase encoding.
And the telephone line through the hybrid circuit (201)
(109). Next, about message communication
Will be explained. In this embodiment, the message is
It is separated as a variable part, and the former is represented by an identifier.
You. Further, in this embodiment, the message communication is mainly described above.
There is one feature in that the identification is performed by the identifier. Identifier and message
Pair with fixed part of message (hereinafter referred to as fixed message)
The response is, for example, as shown in Table 1 (hereinafter referred to as the identifier table).
It is set especially. [0061] [Table 1] In the fixed messages in Table 1, the underlined part is the message.
The variable part of the page. The fixed part of the message like this
Divided into minutes and variable parts in daily life and work
Notice that the required messages are patterned
It is a thing. The variable part is not always necessary. This
Identifier-fixed message correspondence should be at least
It is stored and stored in all of the Ray telephone terminals (11).
There are two ways to store this. One is the case of storing in ROM.
The other is a case where the data is stored in the RAM. First implementation
In the example, an example in which the above correspondence is stored in the ROM will be described.
I do. Since the ROM is a read-only memory,
The above correspondence is stored in advance and prepared for each terminal (11).
There is a need. In this case, the exchange side must
It is not necessary to have, but here is the end
The same storage contents as the ROM at the end (11) are stored in the memory (4
1) Or store it on a floppy disk (39)
Good. The initial input will be described later. Next, message communication will be described. This
There are two modes for message communication in this embodiment.
You. Set message request mode and send message
Request mode. Message setting request mode is
End (11) The operator is absent, etc.
If you cannot respond to 1), set a message in advance.
When a call is made from another terminal (11), the caller
The above message is transferred to the server. The message transmission mode is set to the other terminal (1
When the called party does not answer when calling for 1)
And sends a message to the called party. First, the message setting request mode
explain. To perform this mode, first, the telephone terminal (1)
The key (65) of 1) is operated. This key (65)
Message setting / selection key. At first this key (6
When 5) is pressed, the CPU (125) of the telephone terminal performs this operation.
The state is set to the detection person and the message setting mode. This mode
In the ID, the CPU (125)
The content of "1" is called and displayed on the LCD (51). This
Here, “Gaishutsu, Cho” corresponding to the identifier “1”
Is displayed. This is not the message we need now
Operator presses the message setting / selection key (65)
Push. Then, the content of the identifier “2” is displayed. Less than
Repeat the same operation, the content of the identifier "5" is displayed
Then, the operator presses the confirmation key. As a confirmation key,
The dial pad (102) may be used.
Action keys (67)-(79), (95)-(10
You can choose one from 1) and set it
No. Also functions as one of soft keys (53) to (63)
May be assigned. This completes the fixed message setting.
Done. Next, the variable message "03:00" is input.
Power. This sets the dial pad (102) to "0"
Press "3" "0" "0". The CPU (125)
"0" "3" "0" "0" is displayed on the LCD (51)
03 in the underlined area in the displayed message
00 is displayed. Then, "Kaichuchu 03:00 Ma
Is displayed. At this time, the CPU (125)
In the AM (156), the identifier “5” and the variable message “03”
00 ”is stored as“ 50300 ”. at the same time,
This "50300" is sent to the exchange as data.
I do. This will be described in more detail. Of this data
The transmission is performed in the same manner as the transmission of the control signal of the telephone terminal (11).
Do it. In this embodiment, a ping-pong transmission method is adopted.
Therefore, the control signal video in the format shown in FIG.
Will be used. Also, the data used here
Is a unit of 12 bits. First, the CPU (12
5) sends a message setting request to the exchange. This setting
FIG. 14 shows an example of the request. Here, 12 bits are simple
C0 is a frame synchronization bit, C1
 , C2 indicate the meaning represented by the 12-bit data.
Bits C3 to C10 indicate data C11 to be transmitted, and
This bit is a parity check bit (even in this example). Such 12-bit data is transferred to the CPU
(125) to 12-bit shift register (149)
(Shown in FIG. 8) and sent to the exchange according to the procedure described above.
Will be issued. Next, the message identifier number, variable data
Data (time in message, date, etc.)
Is sent. On the exchange side, the above data
Received by line card (15) and sent to CPU (37)
You. The CPU (37) issues a message setting request.
After receiving and recognizing, the message identification number, variable data
Data in the message registration area of the memory (41).
Remember. Of the message registration area of this memory (41)
The configuration will be described. In this embodiment, ports are supported.
Message creation area in consideration of customer data
Is configured. FIG. 12 shows this specific example. The port is, for example, the line card shown in FIG.
(15) indicates an output terminal on the terminal (11) side. Port number
In this case, the unique address
A number with two bits may be used. Customer Day
Are the type, status, telephone number, and key of the telephone terminal (11).
Attribute such as function assignment. Type of terminal (11)
Use a regular dial phone, touch phone, display
Phone with data terminal, phone with data terminal (for example, computer
N). What is the state of the telephone terminal (11)? State transition diagram
Is the concept of the level used in FIG.
As shown, terminal (11) from the point of view of exchange control
It is a state of. In this embodiment, the state "7"
The feature is that the message set is being set.
You. [0074] [Table 2] Set for customer data corresponding to such ports
Remember the middle message. The messages in this set
It consists of a fixed data section consisting of a separate element and a variable data section.
Here, the identifier is “5” and the variable data part is “0300”.
You. When the inside of the exchange is set as described above,
Terminal (11) other than the terminal (11) that sent the message
From the message sending terminal (11)
I do. The CPU (37) in the exchange is connected to the terminal (11)
And search for customer data corresponding to the port.
You. By this search, the state of the called terminal is checked. Condition
If the state is "0", the line connection is performed.
"5" is state "7" and message is being set
The CPU (37) recognizes this. Thereafter, a message during setting is called, and
Control data to the calling terminal as data "50300"
Is sent out. The sending procedure at this time depends on the message setting.
The same procedure as that for sending from the terminal (11) to the exchange at the scheduled time
Therefore, the CPU (37) in the exchange is shown in FIG.
Calling end via line card (15) etc. in format
Send the above control data to the end. Line card (15) and
Ping-pong transmission method between telephone terminals (11) as described above
Is used. The CPU (1) of the terminal receiving the message transfer
In 25), after recognizing the control data, using the identifier
The contents of the identifier table are called from the memory (157). here
Now, we call “Kaikyuchu: Made” corresponding to “5”.
Will be issued. However, when storing the identifier table
Changes the character corresponding to "Kaichu: Made"
It may be stored as it is, or the character generator
You can prepare it separately and just store the character code.
No. Next, the CPU (125) executes the calling
Display a fixed message and variable data on the LCD (57)
You. In this way, the calling terminal is provided with “Kaichuchu 0
3:00 Made "is displayed and the message is
This means that the message has been sent and displayed. Simultaneous with such display
Displays the number of the called terminal, the operator of the called terminal, etc.
You may do it. Next, the message transmission request mode will be described.
I will tell. This is very urgent even when the called terminal is busy.
This is the mode you need to get in touch. Secretary for example
Wants to get in touch with his boss
You. In such a case, the calling terminal is
A busy tone is transmitted from the communication circuit (23). like this
Receiving a busy tone, the CPU of the telephone terminal (11)
(125) is a key (53) to (63)
Power on, automatic call back, recall, message transfer, interrupt
Assign each function only. At the same time, the LCD (51)
CPO (key) is added to the part corresponding to keys (53) to (63).
Camp-on), ACB (automatic call back), RCL (recall)
And LMG (message transfer) and OUR (interrupt)
indicate. Next, the operator presses the key (59). this
The soft key (59), in this state,
By pressing this key (59),
Forward the message created by the following process to the called party
Will be. First, the message is set by the CPU (12
Displayed for 5). And the message settings mentioned above
As in the request mode, the identifier table is called and the identifier
It is displayed from the content of "1". And key (65)
And a message by operating the dial pad (102)
The fixed part of is determined. Here, the identifier “6” is selected.
Shall be. In this example, no variable data is needed.
Message according to the procedure and format shown in
Is first sent to the exchange. Exchange CPU (37)
When the message transmission request is recognized, the message shown in FIG.
The data in the format
It is transmitted as control data of (11). In this way, the called terminal can communicate.
Messages are forwarded even when busy (and in any state)
Possible, and transfer volume is large because of the use of identifiers
Can be reduced. In the above embodiment, the identifier table is stored in the ROM.
Although the example of storing is explained, naturally the RAM (Ran
dom Access Memory)
Can also be. Moreover, in this case, it is clear from the following description.
Has the effect of In the following description, the floppy disk inside the exchange will be described.
-An identifier from the data terminal (45) to the disk (39)-
At the same time as entering the correspondence for the message,
1) shows the correspondence between the identifier and the message in the initial state.
It is assumed that it has not been stored. Hardware configuration is
It is assumed that this is the same as the above embodiment. First, knowledge of the floppy disk (39)
The input of the correspondence between the identifier and the message will be described.
The data terminal (45) is a maintenance terminal,
When writing a message from (45),
Enter the activation code. For example, Authorization
When the action code is “0003”, the following processing is performed.
When "0002" is set, customer data
And when it is "0001", writing a message
I'll decide. Here, the authorization
Enter the code "0001"
Is an identifier number and a (fixed) message.
7) Recognize. Therefore, this content is
Disk (39) or RAM (41)
Remember in the part. This storage is limited to Table 1.
Not. Thus, the identifier number and the message
Once the correspondence is determined, this stored content is
The process of transferring to (11) is performed. However, it is called transfer
The concept is that information about messages in the switch
It has nothing to do with what is expected. Sand
In the exchange, the above contents may be stored in the ROM.
It is natural. Now, the stored contents (identifier number and message)
Transfer), when the exchange is powered on, a new
When connecting to a terminal, changing messages, adding new items, etc.
Is preferred. First, transfer at power-on
explain. When the exchange is powered on,
To be stored on the floppy disk (39)
Exchange program, required data (see message above)
Data may be included. ) Load and note
(41). Next, the initial pro
Program starts and processing by this program is complete.
After completion, I / O processing and exchange processing by supervisor
Management, background processing, failure processing, etc.
Is executed. Next, the initial program will be described.
You. This program is as shown in FIG.
First, initialize the entire hardware, especially
Start from the process of clearing the data area memory.
You. This is because of the exchange program and the necessary data
Loading alone does not guarantee the initial contents of the data area.
Because it is not. The data area is the line shown below
This is a storage area for data on the mounting status of the card, etc.
And clear the data before storing the correct data.
That is, the memory is being initialized. Next, the line card (15) and the trunk card
The mounting state of the card (21) and the like is checked. For this
An inquiry signal is sent from the CPU (37) to the control signal line (data
Line card (15), tiger
To the link card (21). In contrast, each license
CPU (227) such as a card (15) is mounted
Is sent back to the CPU (37). This reply
Is, for example, the fixed number given to each line card (15).
A unique number may be used.
As a reference value of the comparator (217) shown in FIG.
The lower two bits of the unique address used are omitted
May be used. The reason for discarding the lower 2 bits is that
The unique address originally corresponds to the telephone terminal (11) (port).
In this embodiment, one is set
Four terminals (11) connect to the line card (15)
Other than the lower 2 bits of the unique address
Identifies the line card (15), and the lower 2 bits
Up to the telephone terminal (21). This
However, the terminal (1) connected to the line card (15)
1) If the number changes, the expression of the unique address will change
Thus, the expression of the unique number here also changes. like this
When the CPU (37) receives the response,
Check the implementation of the code (15). Thus, the CPU (37)
Get a map about the implementation of. Next, the telephone terminal (1
The check of the connection state of 1) will be described. The CPU (37) of the exchange sends an inquiry signal
Is transmitted to each terminal (11) as a control signal. this
The format of the inquiry signal in the embodiment is in accordance with FIG.
It's natural. On the other hand, C of the telephone terminal (11)
When the PU (125) receives the inquiry signal, for example,
For example, it sends its own unique number as a reply to the exchange. (This
This will be further described later. ) The CPU (37) receives this response and mounts the terminal (11).
Make a map of the state. Inquiry signal and this
FIG. 18 shows an example of a response to this. In this way
Card (15) and terminal (11)
Is checked and the CPU (37) completes the implementation map.
Can be. Next, the CPU (37) operates the telephone terminal (11).
To initialize. With this initialization,
The talk terminal (11) can transmit and receive. Then, CPU
(37) is read from the floppy disk (39)
The message stored in the memory (41).
All the data are read and sent to the terminal (11). This data transfer is controlled by the terminal (11).
This is performed as transfer of control data. Data format at this time
The plot is shown in FIG. The CPU (37) in the exchange first
Issue a message store request instruction consisting of bits. this
Is received by the CPU (227) in the line card (15).
And temporarily stored in the register (239). this
Then, the control signal bits in the ping-pong transmission format are
To the terminal (11) via the telephone line (109).
Can be In the terminal (11), the reception frame register (14
3) via a 12-bit shift register (147) or the like
Then, it is sent to the CPU (125). According to such a procedure, the message
Memory request, message identifier number, message one after another
It is sent to the terminal (11). CPU (12) of terminal (11)
5) stores the identifier and the message in the RAM (156).
I will remember. And I received a message storage end command
If this is the case, this process is terminated. Thus, the CPU (12) of the telephone terminal (11)
5) Store the sent data in RAM (156)
I do. As a result, the exchange and the telephone terminal (11) are
Will have the same identifier and message. This
This completes the initial program and replaces the normal
Starts. The CPU (37) determines the idle time of the replacement process.
Use and update the implementation map at regular intervals in principle
ing. That is, the connection of the new terminal (11) and the connection of the terminal (1)
1) Change the connection position (change the connection port), etc.
I have. This means that if you get the port
It means automatic change. Changes in customer data
Especially when the new terminal (11) is connected to the system controlled by the exchange.
If this is caused by the above initial program
In the same manner as described above, the identifier and the message are stored in the new terminal (1).
Transfer to 1). In the new terminal (11), the transferred data
The data is stored in the RAM, and is shared with the exchange and other terminals (11).
You will have one set of data. Here, is the terminal (11) connected?
The check as to whether or not there is no will be described in detail. The exchange is constant
Whether or not a terminal is connected to each port periodically
Make an inquiry to check if
ing. The terminal responds to this inquiry.
The switch confirms that a terminal is connected to that port.
Understand. FIG. 21 shows the operation of the exchange at the time of inquiry.
Shown in a row chart. Normal (when the terminal is connected
The switch does not respond to each port
And make inquiries one after another. Connect terminal to exchange
If it continues, there is no response from the point of view of the exchange.
A response is suddenly returned from the port that was used. this
In this case, the exchange repeats the inquiry to the same port three times.
If there is a response to all, the terminal
Recognize that connection has been established. Conversely, the terminal was disconnected from the exchange (the terminal was disconnected).
From the point of view of the exchange,
No response is suddenly returned from the port that was responding. This
In the case of, the exchange queries the same port three times in a row.
And if there is no response for all, the above port
Recognizes that the terminal connected to has been disconnected. Connect a new multi-function key telephone to the exchange
Will be described. As an example, a telephone line (10
9) Also connect a multi-function button (position of terminal A in FIG. 2)
And After the inquiry immediately after connection, the exchange
Recognizes that connection has been made and sends an ID number transmission request
You. On the other hand, the multi-function key telephone (11)
Under the control of U (125), the read-only memory (1
26) terminal identification code fixedly stored in
Control signal), the common bus (123),
Shift register (149), transmission frame register (13
3) Control signal area (C), parity addition circuit (13)
5), NRZ / DP conversion circuit (137), hybrid
Switch side via circuit (139) and telephone line (101)
To send to. On the exchange side, this terminal identification code is
Line card (15)
Data highway (23)
3), the processing system CPU (3) via the I / O (33).
Until 7), the terminal identification code and the port
The number (PN) of the client. The CPU (37) is newly added to the port
It recognizes that the active phone has been connected, and
Stores data (customer data, etc.) corresponding to the end
Set to (41). Also, I / O (3
3), data highway (233) line card (1
5) Multi-function button telephone (end) via telephone line (109)
Terminal A), an identification number for terminal identification (for each terminal)
Different). On the multi-function button telephone side, the identification number
Is a hybrid (139), DP / NRZ conversion circuit
(141), receive frame register (143), shift
Register (147), telephone via common bus (123)
When the terminal CPU (125) receives the data, the CPU (125)
Is a rewritable memory ((126) CE^TwoPROM
The identification number is stored. This
Memory contents are retained even if the phone is powered down.
Be held. This allows the terminal to connect the telephone line
Can be used. Move the current multi-function key phone to another location
The operation will be described. As an example, a telephone line
Call the multi-function button phone connected to (109A)
Change to the sea line (109B) (from terminal A to the end
End B). The telephone lines (109A) and (109B)
Terminal number (PN) 1 for each exchange,Connect to port 2
Shall be continued. Connect this telephone to the line (109
If you remove it from A), you will be contacted
The exchange recognizes that the telephone has been disconnected from the PN = 1 port
You. When this telephone is connected to the line (109B),
The telephone is connected to the PN = 2 port
WasThisAnd the exchange recognizes. From the exchange, PN = 2
Sends an identification number transmission request to the port. On the other hand, the CPU (125)
Controls the identification number stored in the RAM (126)
Send to the exchange as data. On the exchange side,
Issue the line card (15) and data highway (23
3), CPU (37) receives via I / O (33)
I do. The CPU (37) determines the port of PN = 2 from the identification number.
The terminal connected to the port connects to the port of PN = 1 until now
It recognizes that it is a multi-function button telephone that has been used. There
Corresponding to the terminal stored in the memory (41)
(Customer data, etc.) is rewritten. Contents stored as information of PN = 1
To the information of PN = 2 as it is.
As a result, only the operation of connecting the telephone line is the same as before the change
It can be used even after moving in the state. Of course each key machine
Noh assignment is the same. Use a standard telephone other than the multi-function key telephone.
When connecting to the exchange in the embodiment of
The switch connects the terminal to a certain port.
And sends an identification number transmission request.
Therefore, the exchange uses the above terminals for terminals other than the multi-function key telephone.
We recognize that it is the end. At this time, the data corresponding to the terminal is already
If it is set, the next port is queried. Also
However, if the data corresponding to the terminal is not set,
For the maintenance terminal (45), the data corresponding to the terminal (telephone)
Sends a data input request and waits for input. Next, new registration, deletion, change of message, etc.
Is performed on the exchange side. This is a replacement
The processing is executed by I / O processing. First, the terminal
Key-in "ORG" from (45). Then I /
“CODE?” Is displayed by the O processing. Against this
And hit "0001" from the terminal (45). This is
This is an authorization code for message input.
Subsequently, “MODE?” Is displayed by the I / O processing.
You. This means that the message input is new registration or change
Or I / O processing requests to specify whether to delete
It is doing. On the other hand, from the terminal (45),
Key in “NEW”, “CHG” and “DEL”
Just do it. After key-in, "NUMBER?" And "ME
SSAGE? "
Therefore, an identifier and a message may be input. In this way, in the I / O processing, the message
When new registration, change or deletion of a message is completed,
To the background job, and
In the meantime, a message, an identifier (or just a change)
Is sent to the telephone terminal (11). Next, a telephone without a display,
That is, a standard telephone is connected to the switching system in this embodiment.
The message transfer in the case will be described. Here,
Message to voice and transfer it to a standard telephone.
I do. The overall configuration at this time is as shown in FIG.
, A voice synthesis circuit (301) is provided on the exchange (13) side.
The feature is that it is. This speech synthesis circuit (301) is shown in FIG.
As shown, the CPU (303) and the ROM (30)

Perform processing according to the stored program. Also, ROM
(305) contains a word dictionary for speech synthesis and a rule dictionary for synthesis.
Parameter data and the above-mentioned identifier and message
I also remember the correspondence. Of course, this correspondence is based on the RAM (307)
May be stored in the RAM.
There are several ways to set the content as described above.
You. If the message transfer is performed by the exchange,
The status of the transfer destination terminal is obtained from the customer data as shown in
You. As a result, if the transfer destination is a standard telephone, the exchange (1
3) The CPU (37) assigns an identifier (further with variable data).
May be added. ) To the above-mentioned speech synthesis circuit (30).
Send to 1). This is via the data highway (233).
Do it. CPU (303) is I / O (311), common
When an identifier is received via the bus (309), speech synthesis is performed.
Start processing. For example, now, as an identifier + variable data
It is assumed that “50300” has been sent to the CPU (303).
First, the message corresponding to “5” is sent to R
Read from OM (305). And "Kaichuchu 0
3:00 Made ”. This is described below
In this way, voice synthesis is performed and PCM voice data
To data. FIG. 24 shows the processing flow of speech synthesis.
You. For each word in the above message data
Is given a reading and an accent by referring to a word dictionary. This
In the example, the reading “Sanji” for “03:00”
Only is given. Next, accents and poses as phrases
Is given, and the conversion into spoken language is performed. Then, the sound
Based on the voice parameters, regular speech synthesis is performed, and 8KH
PCM data of z-interval "Kaigichu Sanjimade"
can get. This data is transmitted via the PCM highway (17).
Then, it is sent to the line card (15). The PCM data is stored in a line card.
Is converted to an analog audio signal,
1), and message transfer is performed. At this time,
A sound or guidance message indicating that the message is registered
It may be added before the sage. Also, the message transmission
