Abstract

PURPOSE:To allow an exchange to rewrite automatically a data corresponding to a terminal equipment by sending a terminal equipment identification number from the terminal equipment to the exchange when a multi-function key telephone set is moved from a place to other. CONSTITUTION:In reconnecting the multi-function key telephone set connected to a telephone line 109A to a telephone line 109B (movement of the location of a terminal equipment A to the location of a terminal equipment B), the exchange recognizes that the telephone set is removed from the port of PN=1 and connected to the port of PN=2. An identification number sending request is sent from the exchange to the port of PN=2 and a CPU 125 in the telephone set sends the identification number stored in a RAM 156 to the exchange as a control data. The identification number is received by a CPU 37 at the exchange side and the data corresponding to the terminal equipment stored in a memory 41 is rewritten.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention automatically rewrites data (customer data, etc.) corresponding to the terminal when connecting a multi-function button telephone terminal, etc. in an electronic exchange. Concerning exchange maintenance free system.

[Technical background of the invention and its problems]

In conventional electronic switching systems, when a new terminal is connected to an exchange, data about the terminal such as which port (terminal) and what type of terminal (DP, PB, multi-function button telephone, etc.) is connected to the exchange is sent to the exchange. TT
I had to type from Y (70).
・Also, when moving the terminal due to office relocation, etc.,
In the same way as when connecting a new terminal, from the TTY connected to the exchange, the number (PN) of the boat to be connected, the type of terminal, and in the case of a multi-function button telephone, the functions assigned to each key. I had to re-enter data related to nine terminals, including speed dials, auto dials, etc.

This is OK.If you unplug the cord and connect another cord to use the terminal you have been using in one place in another place, data corresponding to the terminal will be sent from TTY (70). It did not work properly without rewriting the . In the case of multi-function key phones, even if the terminal types match, the functions assigned to each key will change.
In the end it didn't work properly.

[Purpose of the invention]

The present invention eliminates the above drawbacks and provides an exchange maintenance-free system that automatically rewrites data (customer data, etc.) corresponding to the terminal in the electronic exchange when a multi-function button telephone terminal is newly connected or moved. The purpose is to provide.

[Summary of the invention]

In the present invention, the terminal identification number is stored or fixedly held in the multi-function button telephone, and when the terminal is newly connected to a certain boat, the terminal sends the identification number to the exchange, and The switchboard recognizes that a multifunction key telephone has been newly connected to the boat, and sets data corresponding to the terminal of this boat.

In addition, when a multi-function key telephone is moved from one place to another (from one boat to another), the terminal sends a terminal identification number to the exchange, so that the exchange can identify where the terminal was moved from. The system recognizes the terminal and automatically rewrites the data corresponding to the terminal, such as the functions assigned to each key (speed dial, auto dial, etc.).

〔Effect of the invention〕

Based on the above, when connecting a new multi-function telephone to an exchange, simply connect the cord to the terminal, and the terminal will no longer be used.
Additionally, even if you move a multi-function phone, you can simply replace the cord and use it in its original state (the functions assigned to each key do not change, etc.). A free maintenance method has been realized that reduces the hassle of typing.

In this embodiment, messages are also input from this data terminal (45).

Next, a transmission method between the telephone terminal (11) and the line card (15) will be explained.

As mentioned above, this embodiment uses a two-wire bidirectional burst transmission method.

In Jin's system, signals are sent and received between the telephone terminal (11) and the switching system (line card (15)) like a ping-pong game. As shown in FIG. 3, signals in a predetermined format are transmitted in bursts from the line card (15) to the telephone terminal (11). In contrast, signals are transmitted in bursts from the telephone terminal (11) to the line card (15). This is done within 125V sec.

With such a configuration, the signal from the telephone line (109) is obtained as digital data, and the digital data is subjected to diphase encoding and sent out to the telephone line (109)K.

Next, the operating clock of the telephone terminal (11) will be explained. In this embodiment, the operating clock is obtained from the frame detection circuit (167) and timing control circuit (169) shown in FIG. That is, the frame detection circuit (1
67), a frame synchronization bit is detected from the received signal, and a clock signal is generated in synchronization with this detection timing.

This generates a timing signal Tl-T in response to the above frame detection from a clock signal from a clock generator (not shown) (provided between the timing generation circuit (169)).

The timing signal T1 is a clock signal of 8KHz, the timing signal T2 is a clock signal of 64KHz, the timing signal T3 is a clock signal of 256K''Hz, and the timing signal T4 is a clock signal of 2MHz.Also, as mentioned above, for the transmission frame register (133), Data is written from the codec & filter (127), l10 (145), and 12-bit shift register (149), and data is read from the parity addition circuit (135), so it is necessary to shift the phase between writing and reading. Of course there is. Receive frame register (143)
The same applies to Ic.

Next, the line card (15) will be explained according to FIG. This line card (15) includes a hybrid circuit (201), a transmitting/receiving circuit (203), and a receiving frame register (205).

Hybrid circuit (201) and transmitter/receiver circuit (203)
The configuration is the same as the specific configuration shown in FIG. In other words, the signal of the telephone line (109) is decoded and NRZ
Convert the NRZ signal to a diphase signal (D
This is used to convert it into a P-flaw signal. Here, the NRZ signal is
It can be considered the same as digital data. The signal that has been decoded has a frame synchronization bit (F) detected in the synchronization signal detection circuit (204), and based on this signal, the NRZ signal is sent to the reception frame register (204).
205) Ic Rotosur. In this case, the data of the 2-bit inverted 9-bit diagram from the beginning (counting from the frame synchronization bit (F)) is stored in the audio signal area. The 10th bit data is stored in the data area. The 11th bit data is stored in the control signal area.

Next, the data in the audio signal area and data area are transferred to registers (207) and (209). For these registers (207), (209), a multiprefter (213) and a counter (215), ! - and a comparator (217).

The registers (207) and (209) send stored data to the multiplexer based on the clock signal. This four clock signal is generated by the clock generator (26) shown in FIG.
) from the clock signal line (219). This clock signal is also supplied to a counter (215) and counted there. The counter (215) is initialized by the PCM frame synchronization signal.

This PCM7 frame synchronization signal is a frame signal! (22
1) Sent from l10 (33) via l. Although it is omitted in FIG. 2, it can be considered that it is provided together with the 20M Highway (17) or the like.

Therefore, the counter (215) counts the clock signals from the beginning of the PCM frame, and the comparator (215) counts the clock signals from the beginning of the PCM frame.
In step 17), a match with a predetermined value is detected. This predetermined value is a unique address determined for each line card, and may also be a time slot number assigned to each line card (or telephone terminal (11)) as described later. be. In addition, if multiple telephone terminals (11) are set to the line card (15), if the unique address and the number of counting clock signals match in the comparator (217), this result is sent to the multiplexer. (213) and a demultiplexer (223) to be described later. The multiplexer (213) receives this and registers (207), (
209) and multiplexes the contents of PCM Highway (17).
Send to. This PCM highway (17) is connected to the time switch circuit (19) as described above.

On the other hand, the control signal stored in the control signal area of the reception frame register (205) is stored in the 12-bit shift register (211). Once 12 bits have been accumulated, one control signal is sent via path (225) t-,
Sent to CPU (227)K. The CPU (227) decodes the stored contents of the memory (229) through certain processing and, if necessary, sends the contents to the data highway (233) via the l10 (231). The data sent to the data highway (233) is
(37), and undergoes predetermined processing.

The above is the transmission from the telephone terminal (11) to the exchange side. Next, the transmission from the exchange side to the telephone terminal (11) will be explained. PCM audio data sent via the PCM highway (17) is time-division multiplexed.

This data is loaded into the line card (15) at the demultiplexer (223). As aforementioned,
Each line card (15) is assigned a unique address, which is also the number of the time slot assigned to each line card (15).

As mentioned above, the comparator (217) checks whether the clock value counted from the start of the PCM frame matches the unique address, and when they match, the demultiplexer (223) is also notified of this result. The demultiplexer (223) receives this and separates the received PCM signal into voice and data, and registers (235) and (23) respectively.
7) Transfer to. The registers (235) and (237) operate by receiving a clock signal from the clock signal line (219).

The data sent via the data highway (233) is data necessary for exchange control, and is distinguished from the data transmitted via the PCM highway (17) described above. Data sent via the data highway (23) t- is sent to the CP via l10 (231).
It is sent to U (227) and further stored in the register (239).

Next, the contents of registers (235), (237), and (239) are transferred to the transmit frame register (241).

This transmit frame register (241) is divided into three areas: a receive frame register (205),
Or, the reception frame register (1) at the telephone terminal (11)
33) etc. This transmit frame register (2
The contents of 41) are sent to the transmitting/receiving circuit (2α3). In this circuit (203), the data is subjected to diphase encoding and sent to the telephone line (109) via the hybrid circuit (201).

Next, message communication will be explained. In this embodiment, a message is separated into a fixed part and a variable part, and the former is represented by two identifiers. Furthermore, one feature of this embodiment is that message communication is mainly performed using the above-mentioned identifier.

The correspondence between an identifier and a fixed part of a message (hereinafter referred to as a fixed message) is set, for example, as shown in Table 1 (hereinafter referred to as an identifier).

Among the fixed messages in Table 1 and Table 15, the underlined parts are the variable parts of the message. The reason for dividing the message into a fixed part and a variable part is to focus on the fact that messages necessary in daily life and work are patterned. Variable parts are not always necessary.

This identifier-fixed message correspondence is maintained and stored in at least all of the displayed telephone terminals (11). There are two ways to remember this. One is to store in ROM, and the other is to store in RAM. In the first embodiment, an example will be described in which the above correspondence is stored in the ROM.

Since the ROM is a read-only memory, it is necessary to store the above correspondence in advance and prepare it in each terminal (11). In this case, it is not necessarily necessary for the exchange side to have this support in advance, but here the terminal (11
) The same storage contents as the ROM in the memory (41) or
Store it on the floppy disk (39). The initial input will be described later.

Next, message communication will be explained. There are two modes of message communication in this embodiment. These are a message setting request mode and a message sending request mode.

In the message setting request mode, when the operator of the telephone terminal (11) is absent and cannot answer the telephone (11) from now on, a message is set in advance and the other terminal (11)
When a call is made from 1), the above message is transferred to this caller. In the message sending mode, when a call is made to another terminal (11) and the called party does not respond, a message is sent to the called party.

First, the message setting request mode will be explained. To use this mode, first, press the key (
65) t-operate.

This key (65) is a message setting/selection key. When you first press this key (65) t-, the telephone terminal's CPU (
125) sets this operating state to the detected person and message setting mode.

In this mode, the CPU (125) calls the contents of the identifier "1" from the identifier and displays it on the LCD (51). Here, "Gaishiera, Chivyki" corresponding to the identifier "1" is displayed. This is not the message you need right now, so the operator must press the message setting/selection key (
65). Then, the contents of the identifier "2" are displayed. Thereafter, the same operation 1 is repeated, and when the contents of the identifier "5" are displayed, the operator presses the confirmation key. As the confirmation key, you may use on the dial pad (102), or you can use the funk syllan keys (67) to (79') S(
95) to (101) may be selected and set appropriately. Also, soft keys (53) to (63)
A function may be assigned to one of the following. The fixed message settings are now complete.

Next, the variable message r03:OOJ is input. This changes the dial pad (102) to rOJr3JrOJr
Press OJ. CpU (125) is this r OJ r
3 J r OJ rOJ in the underlined area of the message displayed on the LCD (51) oa:
o.

is displayed. Then, “Kaigicheu 03:00 Made”
is displayed.

At this time, the CPU (125) stores the identifier "5" and the variable message r0300J in the RAM (156) as r5030.
Store it as 0J. At the same time, with r50300J
Send it as data to the e-switch.

This will be explained in more detail. This data is sent in the same manner as the control signal of the telephone terminal (11). In this example, since the ping-pong transmission method is adopted, the fourth
The control signal bits in the format shown in the figure will be used. Furthermore, the data itself used here is made up of 12 bits.

First, the CPU (125) sends a message setting request to the exchange. An example of this setting request is shown in FIG. Here, one unit is 12 bits, but CG is a frame synchronization bit, C1 and C2 are bits that indicate the meaning of this 12-bit data, and 03 to CIO are data to be sent. C11 is a parity check bit ( In this example, it is an even number). Such 12-bit data is processed by the CPU (1
25) to 12-bit shift register (149) (8th
(as shown in the figure) and is sent to the exchange according to the procedure described above. Next, the message identifier number, variable data (
(time, month, date, etc.) of the message, a message setting request is sent.

On the exchange side, the above data is sent to the line card (
15) and sends it to the CPU (37). CPU (3
7) After receiving and recognizing the message setting request,
Recognizes message identification numbers and variable data, memory (
41) is stored in the message registration area.

The configuration of the message registration area of this memory (41) will be explained.In this embodiment, the message registration area is configured to correspond to boats, and the message registration area is configured taking customer data into consideration.

A concrete example of this is shown in FIG. For example, the boat weighs 1g
This refers to the output terminal on the terminal (11) side of the line card (15) in Figure 2. When we say boat number, here we mean 2 pins for the aforementioned unique address)? Just use the added number.

The customer data includes attributes such as the type, status, telephone number, and key function assignment of the telephone terminal (11). Terminal (11)
Types of telephones include ordinary dial telephones, goophones, telephones with data terminals, and telephones with data terminals (for example, combiator telephones). The state of the telephone terminal (11) is a level concept used in state transition diagrams, and as shown in FIG. 13 and Table 2, the state of the telephone terminal (11) is
11). This embodiment is characterized in that a state "message setting in progress" is provided as state "7".

Table 2: Messages during setting are stored for customer data corresponding to such boats. The message in this set consists of a fixed data part consisting of an identifier and a variable data part.

Here, the identifier is "5" and the variable data section r0300J.

Assume that when the exchange is set up in this manner, a call is made to the message sending terminal (11) from a terminal (11) other than the terminal (11) that sent the message. The CPU (37) in the exchange receives the call from the terminal (11),
Search for boat-compatible customer data.

With this search, the state of the called terminal is 1kv! 4 pels.

If the status is "0", a line connection is made, but here the terminal "
'kcPU (37) recognizes that the 'kcPU (37) is in the state '7' and that the message is being set. Thereafter, the message being set is called and the data "50300" is sent as control data to the calling terminal.

The sending procedure at this time is the terminal (11) when setting the message.
The procedure is the same as the sending procedure from C to the exchange.
The PU (37) sends the control data to the calling terminal via the line card (15) or the like in the format shown in FIG. Line card (15) and telephone terminal (11)
As mentioned above, the ping-pong transmission method is used.

The CPU (125) of the terminal that received the message recognizes the control data and then uses the identifier to call up the contents of the identifier table from the memo IJ (157).

Here, “Kaigicheui” corresponds to “5”.

: You will be calling "Made". However, when storing the identifier table, the characters corresponding to "Kaigichew: Made" may be stored as they are, or the characters may be prepared for each character generator sound and only the character codes may be stored.

Next, the CPU (125) displays the called fixed message and variable data tLcD (57). In this way, the calling terminal displays the message ``Kai Gichi Tametsu 03:00 Made'', which means that the message has been transferred and displayed. At the same time as this display, the number of the called terminal,
The called terminal operator, etc. may also be displayed.

Next, the message sending request mode will be explained. This mode is necessary when you want to contact the called terminal as soon as possible even when the called terminal is busy. For example, when a secretary urgently contacts his boss to inform him of a visitor.

In such a case, a busy tone is sent to the calling terminal from the tone circuit (23) of the exchange. When such a busy tone is received, the CPU (1) of the telephone terminal (11)
25) assigns the functions of camp-on, automatic call back, re-call, message transfer, and interrupt to the keys (53) to (63). At the same time, CPO (camp on), ACB (automatic call back), RCL (recall),
Displays LMG (message transfer) and 0UR (interrupt).

Next, the operator presses key (59) t-. In this state, this soft key (59) is a message transfer key, and by pressing this key (59), a message created by the following process will be transferred to the called light. First, the message settings are CPU (125)
displayed for. Then, in the same way as in the message setting request mode described above, the 1 identifier table is called up, and if the identifier "1"
will be displayed starting from the content. The fixed portion of the message is determined by operating the keys (65) and dial pad (102). Here, it is assumed that the identifier "6" is selected. In this example, no variable data is needed;
A message is first sent to the exchange according to the procedure and format shown in Figure 5.

When the CPU (37) of the exchange recognizes the message sending request, it sends the data in the format shown in FIG. 15 as is to the called end as control data for the terminal (11).

By doing so, messages can be transferred even when the i-call terminal is in a call (or in any state), and since the identifier is used, the amount of transfer can be reduced significantly.

In the above-mentioned embodiment, an example was explained in which the identifier table is stored in tROM, but naturally the RAM (Random Acc
ess Memory). Moreover, in this case, at the same time that the identifier-message correspondence is input from the data terminal (45) to the bee disk (39) as described below, the identifier-message correspondence is stored in each telephone terminal (11) in the initial state. It is assumed that the hardware configuration is the same as that of the previous embodiment.

First, the input of the identifier-message correspondence to the 74P disk (39) will be explained. Data terminal (
45) is a maintenance terminal, and when transferring a message from this terminal (45), an authorization code is input. For example, when the authorization code is ro003J, the following processing is diagnostic, and r
For 0002J, set the customer data and ro.
When using oolJ, decide to write a message.

Here, the authorization code r OO01J
t-The CPU (37) recognizes that the subsequent data are an identifier number and a (fixed) message. Therefore, this content is stored in nine parts of the floppy disk (39) or the RAM of the memory (41). This stored content is not limited to Table 1. Once the correspondence between the identifier number and the message has been determined in this way, a process is performed to transfer the stored contents to each telephone terminal (11). The concept of forwarding and forwarding is not directly related to when information about messages within an exchange is prepared. That is, it goes without saying that the above contents may be stored in the ROM within the exchange.

Now, the above memory contents (correspondence between identifier numbers and messages) are transferred when the switch is turned on, when a new terminal is connected,
It is preferable to do this when changing a message or adding new items. First, transfer at power-on will be explained.

When the exchanger is powered on, it loads the exchange program stored on the floppy disk (39) and necessary data (which may also include data regarding the aforementioned messages), as shown in Figure 16. and memory (41
). Next, an initial program to be described later is started, and after the processing by this program is completed, the supervisor executes I10 processing, exchange processing, background processing, failure processing, etc. in priority order.

Next, the initial program will be explained. As shown in FIG. 17, this program starts with initializing the entire hardware, especially clearing the data area memory. This is because the initial state of the data area cannot be guaranteed only by loading the exchange program and necessary data. The data area is a storage area for data regarding the mounting state of line cards and the like as shown below, and by clearing the memory, the memo IJe is initialized before storing the correct data.

Next, line card (15),) rank card (21)
Check the implementation status of etc.

For this purpose, an inquiry signal is sent from the CPU (37) to the line card (1) using the control signal line (data highway).
5), and send it to the trunk card (21). On the other hand, the CPU (227) of each line card (15) etc.
A response indicating that it is implemented is sent back to the CPU (37). For this reply, for example, a unique number given to each line card (15) may be used. As a unique number, the comparator (217) shown in FIG.
It is sufficient if the lower two bits of the unique address used as the base value are omitted. Here, the lower two bits were discarded because this unique address was originally set for the telephone terminal (11) (port), and in this example, one line card (15) has four Since the terminal (11) is connected, the line card (15) is
is identified, and the telephone terminal including the lower two bits (21)
Up to f, it is identified. Naturally, if the number of terminals (11) connected to the line card (15) changes, the representation of the unique address will also change, so the representation of the unique number here will also change. By receiving such a response 'kcPU (37), the installation of the line card (15) etc. is confirmed. Thereby, the CPU (37) obtains a map regarding the mounting of the card.

Next, checking the connection state of the telephone terminal (11) will be explained. The CPU (37) of the exchange sends the inquiry signal as a control signal to each terminal (11). Naturally, the format of the inquiry signal in this embodiment follows FIG. On the other hand, C of the telephone terminal (11)
When P U (125) receives the inquiry signal,
For example, it sends its own unique number to the exchange as a response.

(This will be discussed further later.) CPU (37) if
In response to this response, a map is created regarding the mounting status of the terminal (11). FIG. 18 shows an example of an inquiry signal and a response thereto.

In this way, the mounting states of the cards (1, 5) and terminal (11) are checked, and the CPU (37) can complete the mounting map. Next, the CPU (37) initializes the telephone terminal (11). This initialization.

Otherwise, the telephone terminal (11) is capable of sending and receiving calls. Subsequently, the CPU (37) reads data regarding the message read from the floppy disk (39) and stored in the memory (41), and sends it to the terminal (11).

This data transfer is performed as control data transfer to the terminal (11).

The data at this time was 7 Ohmatsu)? It is shown in FIG. The CPU (37) in the exchange first issues a message storage request command consisting of 12 bits. This is the line card (1
5) is received by the CPU (227) in the register (
239). Thereafter, the control signal bits in the pin-bong transmission format are read and sent to the terminal (11) via the telephone line (109). At the terminal (11), the receive frame register (14
3) The data is processed through all the 12-bit shift registers (147) and sent to the CPU (125). Through such a procedure, the message storage request, the message identifier number, and the message are sent one after another to the terminal (11). Terminal (11
) CPU (125) sends the identifier and message to RA.
It is stored in M (156). When receiving a message storage termination command, this processing is terminated.

In this way, the CPU (125) of the telephone terminal (11) stores the sent data in the t-RAM (,156). As a result, the exchange and the telephone terminal (11) have exactly the same identifier and message. This completes the initial program and starts the normal exchange program.

The CPU (37) basically updates the mounting map at regular intervals, using the free time of the exchange process. That is, a new terminal (11) is connected, the connection position of the terminal (11) is changed (the connection boat is changed), and the like.

This is 1 if it is compatible with boats. This often involves automatic changes to customer data. If a change in customer data is caused, in particular, by the connection of a new terminal (11) to the system controlled by the exchange, the identifier and message are transferred to the new terminal (11) in the same manner as the initial program described above.
). The new terminal (11) stores the transferred data in its eRAM and has the same data as the exchange and other terminals (11).

Here, checking whether the terminal (11) is connected will be explained in detail.

The exchange makes inquiries to each boat at regular intervals to check whether the terminal is connected or not.

When the terminal responds to this inquiry, the exchange recognizes that the terminal is connected to that boat.

FIG. 21 is a flowchart showing the operation of the exchange at the time of inquiry.

During normal times (other than when a terminal is connected or unplugged), the exchange queries each boat in turn. When a terminal is connected to an exchange, from the perspective of the exchange, a response suddenly returns from a boat that had not responded before. In this case, there are 3 exchangers on the same boat.
The inquiry is repeated several times, and if there is a response to all the inquiries, it is recognized that a terminal is connected to the boat.

Conversely, when a terminal is unplugged from the exchange (the terminal is disconnected), from the perspective of the exchange, the boat that had been returning normal responses suddenly stops responding. In this case, the exchange sends inquiries to the same boat three times in a row, and if there is no response to all of them, it recognizes that the terminal connected to the boat has been disconnected.

A case will be explained in which all new multifunction button telephones are connected to the exchange. - As an example, assume that a multi-function button is connected to the telephone line (109) (the position of the terminal person in Fig. 2). Upon inquiry immediately after connection, the exchange recognizes that the terminal is connected and sends an identification number transmission request.

On the other hand, the multi-function button telephone (11) has a CPU (
125) under the control of the read-only memo IJ (1
26) Terminal identification code (specific to the model) ``l!: Control signal, which is fixedly stored in the common bus (123
), shift register (149), control signal area (C) of transmission frame register (133), parity addition circuit (
135), the NRZ/DP conversion circuit (137), the hybrid circuit (139), and the telephone line (101). ), the processing system CPU (37)t transmits the terminal identification code and the number (PN) of the boat that received it via the data highway (233) and I10 (33). CPU (
37) recognizes that a new multi-function phone has been connected to the above boat, and with these two alerts, the data corresponding to the terminal (
customer data, etc.) is set in the memory (41). In addition, l10 (33) and data highway (
233) Sends an identification number (different for each terminal) for terminal identification to the multifunction key telephone (location of the terminal person) via the line card (15) and telephone line (109). On the multi-function button phone side, enter the above identification number into the hybrid (1
39), when the telephone terminal CPU (125) receives it via the DP/NRZ conversion circuit (141), reception frame register (143), shift register (147), and common bus (123), the cpU (125) can be rewritten. The above-mentioned identification number is stored in a memory (126) which may be constructed from a CE PROM. The contents of this memory are retained even if the phone is powered down. This makes the terminal ready for use simply by connecting the telephone line.

This section explains how to move a multi-function button phone in use to another location.

As an example, assume a case where a multi-function button telephone that is connected to the telephone line (109A) is transferred to the telephone line (109B) (moved from the terminal's location to the terminal B's location). It is assumed that the telephone lines (109A) and (109B) are each connected to a boat with terminal number (PN) 1.2 of the exchange. Line this phone (109A)
When the telephone is removed from the boat with PN=1, the exchange recognizes that the telephone has been removed from the boat with PN=1 due to the above-mentioned inquiry. When this telephone is connected to the line (109B), the exchange recognizes by inquiry that the telephone is connected to the boat with PN=2. The exchange sends an identification number transmission request to the boat with PN=2. In response, the CPU (125) in the telephone sends the identification number stored in the RAM (126) to the exchange as control data.

On the exchange side, the above identification number is sent to the line card (15),
The cpU (37) receives it via the data highway (233), l10 (33)t'. The CPU (37) recognizes that the terminal connected to the boat with identification number ep N -2 is the multifunction key telephone that was previously connected to the boat with PN=1.

Therefore, data (customer data, etc.) corresponding to the terminal stored in the memory (41) is rewritten. P.N.
=10 information, and transfer it to the information of 9 contents 't, PN=2 as it is.

As a result, the device can be used even after moving in the same state as before the change, just by connecting the telephone line.

Naturally, the functions of each key are the same.

When connecting a standard telephone other than a multifunction button telephone to the exchange in this embodiment, the exchange will know that a terminal has been connected to a certain boat by the above inquiry.
An identification number transmission request is sent, but since there is no response, the exchange recognizes the terminal as a terminal other than a multi-function key telephone. At this time, if data corresponding to the terminal has already been set, the next boat is queried. If data corresponding to the terminal is not set, a request to input data corresponding to the terminal (telephone) is sent to the maintenance terminal (45), and the system waits for input.

Next, the case where new message registration, deletion, modification, etc. are performed on the exchange side will be explained.

This is executed in I10 processing as processing by the exchange. First, key in "oRG" from the terminal (45).

Then, by I10 processing, rcODE? J is displayed. In response, type rooolJ from the terminal (45). This is an automatic 2-easesion code for message input. Subsequently, by I10 treatment, rMODE?
J is displayed. This specifies whether the message input is for new registration, modification, or deletion.
This is because the processing requires it. On the other hand, the terminal (4
5), rNEWJ, “CHGJ, rDE
Just key in LJ.

After key-in, rNUMBER? J and rMESSAGE
? You will be asked J, so just follow this and enter the identifier and message.

In this way, in I10 processing, when the new registration, modification, deletion, etc. of the message is completed, this fact is notified to the package ground zipper, and during the conversion process, the message, identifier (only the changed part is fine) ) is a telephone terminal (
11).

Next, message transfer when a telephone without a display, that is, a standard telephone, is connected to the switching system in this embodiment will be explained. Here, it is assumed that the message is converted into voice and transferred to a standard telephone.

The overall configuration at this time, as shown in FIG. 22, is characterized in that a speech synthesis circuit (301) is provided on the exchange (13) side.

As shown in FIG. 23, this speech synthesis circuit (301) includes a CPU (303), a ROM (305), and an RA.
It is fully equipped with M (307) and l10 (311). C
The PU (303) performs processing according to a program stored in the ROM (305). Also, ROM (305)
It also stores a word dictionary for speech synthesis, parameter data for rule synthesis, and the correspondence between the above-mentioned identifiers and messages. Of course, this correspondence is RAM (307)
It may be stored in When storing the data in the RAM, there are several methods of setting the contents as described above.

When a message transfer is performed by an exchange, the status of the transfer destination terminal is obtained from customer data as described above. As a result, if the transfer destination is a standard telephone, the CPU of the exchange (13)
(37) sends the identifier (in some cases variable data may be further added) to the above-mentioned speech synthesis circuit (301). This is done via the data highway (233).

CPU (303) is l10 (311), common bus (30
9) After receiving the identifier via t-, the speech synthesis process is started. For example, now r50 as identifier + variable data
Assume that 300J is sent to the CPU (303). first,
On the other hand, the message corresponding to "5" is stored in ROM (
305). And “Kaigicheu 03:0
Convert to "0 made" form. As described below,
Performs voice synthesis and converts to PCM voice data at 8KHz intervals.

FIG. 24 shows a processing flow of speech synthesis. The pronunciation and accent are assigned to the above message data by referring to a word dictionary for each word. In this example, r
03: The reading "Sanji" is given to OOJ.

Next, accents and pauses as phrases are given,
Conversion to spoken language takes place.

Subsequently, regular speech synthesis is performed based on the speech parameters, and PCM data "Kaigichu Sanjimade" at 8 KHz intervals is obtained.

This data is sent to the line card (15) via the PCM highway (17). This PCM data is
At the line card, it is converted to an analog voice signal and sent to a standard telephone (321) for message forwarding.

At this time, a sound or a message indicating that the message is a registered message may be added in front of the message.

Alternatively, recovery may be performed until the user hangs up the handset at the standard message sending money telephone (321).

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments. For example, messages may be distributed to all two cards such as the CPU memory of an exchange, a trunk card, etc., and stored in the memory of each card, and the transmission method, format, etc. between an exchange and a telephone terminal may also be determined according to the present invention. It is not limited to. CRTs and LEDs are also used in telephone terminals.

An LCD or any other type of display may be used, and the key arrangement and key operations are not limited to those in this embodiment. Even when selecting a message, the identifier may be directly selected using a dial pad, for example, and is not limited to this method. It is clear that a data terminal that can be connected to a telephone terminal, such as a tablet, is not necessary.

Furthermore, it is clear that the message examples and control signal codes are not limited to those of this embodiment.

Furthermore, the setting of identifiers for messages is not limited to the embodiments. In the example, messages that are frequently used within the company are considered to be fixed messages, and these are identified using identifiers.However, the type of message to be assigned an identifier can be arbitrarily determined by the system. It is. Further, as the identifier, numbers may be given as in the embodiment, or symbols may be used. Alternatively, a memory address may be used as the identifier.

Furthermore, messages do not necessarily need to be common to all telephone terminals, and messages that can be used by telephone terminals may be limited.
