Description

The present invention relates to a telephone exchange device with an information storage device.

  A facility equipped with a large number of terminal devices such as telephones generally uses a private branch exchange (hereinafter referred to as PBX). Recently, in order to more conveniently transmit information, an electronic mail apparatus is attached to the PBX.

  An electronic mail apparatus (hereinafter simply referred to as a mail apparatus) is an apparatus that accumulates information such as voice information converted into an electronic signal and can send it to a desired destination as necessary. is there. By attaching a mail device to the PBX and operating the mail device from a terminal device such as a telephone via the private branch exchange, an information registration operation (an operation for accumulating information in the case of voice information) Various recording devices), information retrieval operation (reproduction operation in the case of voice information), information erasure operation (operation to erase unnecessary information), etc. Can be used.

  Representative examples of these various uses include, for example, proxy reception and broadcast communication. In the proxy reception, when there is no communication partner, the contents to be transmitted are temporarily stored in the mail device, and later, the partner is called from the mail device, or the partner calls the mail device. , It conveys the accumulated content. In addition, in the case of broadcast communication, the contents to be transmitted to a plurality of destinations are stored in a mail device, and those communication destinations are called from this mail device, or those destinations call the mail device, so that all of them It is intended to communicate to.

  As a method for enabling the mail device to be operated from a terminal device such as a telephone, a service number (service code) is determined in advance for each of various services (various operations) of the mail device, and this service number is a push button signal. If it is sent to the mail apparatus (hereinafter referred to as a PB signal), the mail apparatus responds to it.

  Accordingly, in the conventional general operation method when using the mail device, the user operates the push button of the terminal device (that is, sends a PB signal) to call the mail device, and then further pushes the push button. To send the service number as a PB signal.

  However, in the conventional private branch exchange with an electronic mail device as described above, when the mail device is highly functional and the type of service is increased, the number of digits of the service number is correspondingly increased, Therefore, there is a problem that it is difficult for the user to memorize all the numbers necessary for one operation. Therefore, there has been a contradiction that an increase in functionality of the mail device leads to a decrease in operability.

  In addition, the use of the mail device is mainly unilateral recording from the caller to the mail device, and when the outside caller is not used to using the mail device, there is a problem that the mail device is not used. there were.

  In addition, if the user on the information receiving side is informed that the information addressed to him / her is registered in the mail device, he / she feels great trouble calling the mail device to retrieve the information. If there is no registration information addressed to you, but you have to repeatedly call the mail device and there is actually no registration information, the user's mental burden is heavy. . For this reason, there is a tendency to neglect confirmation of the presence / absence of information, resulting in an increase in non-delivery of information, resulting in a problem that the mail apparatus is not fully utilized.

The present invention has been made to solve the above problems, and an object of the present invention is to use an e-mail function with a simple operation and without requiring an operation of an external caller. In addition, a telephone exchange device with an information storage device is provided that enables recording of a call content as it is and allows an outside caller to easily record a message on an e-mail device, and thus has excellent convenience. It is in.

In order to achieve the above object, the present invention connects a terminal device having a call recording key and a call end key and a station line, and stores voice information related to a call between the terminal device and the station line as an information storage device. In the telephone exchange device that enables recording, the call recording means that enables the information storage device to record voice information related to a call between the terminal device and the office line in response to the call recording key operation of the terminal device. When the terminal that the call recording key operation the call recording key operation sound information has been performed in a state in which recording by the information storage apparatus according to the call between the terminal device and the office line made were made In accordance with the end call key operation of the device, the station line is released , and the terminal device on which the call recording key operation is performed and a connection means for connecting only between the information storage device In addition, the terminal device Comprising a plurality of keys that can be allocated to any function, the telephone exchange apparatus, information for assigning a call recording function on the first key of the plurality of keys, call end to the second key of the plurality of keys Storage means for storing information to which a function is assigned, whereby the first key is assigned to the call recording key and the second key is assigned to the call end key, respectively. is there.

  With such a configuration, the contents of the call can be recorded in the mail device by the operation of the internal responder without the operation of the caller, and the caller can communicate the message by conversation with the responder. As described above, the message can be registered without a sense of incompatibility compared with the method of registering the message in the mail device, and the operability when using the mail device is remarkably improved.

  The present invention can use the e-mail function with a simple operation and does not require the operation of an external caller, and can record the call content as it is, so that even an external caller can easily record. A message can be recorded in the electronic mail apparatus, and therefore, an excellent effect is achieved that information can be easily and reliably transmitted through the mail apparatus.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(These terminals are generally represented by reference numeral 300 in the following description).
1- (1) Private branch exchange (PBX)
A private branch exchange (PBX) 100 includes a speech path unit 102, and a central processing unit (CC) 106 is connected to the speech path unit 102 via a bus 104. The central processing unit 106 not only controls the entire PBX 100 but also exerts influence on the mail device 200 and each terminal 300, which will be described in detail later.

  The bus 104 is further connected to a storage device (MM) 108 for storing various control data, processing states, processing programs, and the like, and an external input device 110 configured as a maintenance panel (MP) is connected to the bus 104. It is connected via a device (IOC) 112. The storage device 108 stores not only data relating to the operation of the PBX 100 itself but also data relating to the mail device 200 and each terminal 300, which will be described in detail later.

  The PBX 100 further includes a plurality of line circuits 114 for extension connection, an attendant control device 116, an office line trunk 118, a mail interface circuit (MIF) 120, a conference trunk (CFT) used for three-party calls, etc. 122 and the like, all of which are connected to the speech path unit 102.

The PBX 100 is connected to the public network 404 via the office line trunk 118, and an external telephone connected to the public network 404 is schematically shown at 406 in the figure. Further, a relay stand 402 is connected to the PBX 100 via a relay stand control device 116.
1- (2) Electronic Mail Device The electronic mail device (hereinafter referred to as mail device) 200 uses a so-called voice mail device (VMS) in the system of this embodiment.

  The mail apparatus 200 includes an information storage unit 202 and a controller 204. The information storage unit 202 is connected to one of the line circuits 114 of the PBX 100, and the controller 204 is connected to the MIF 120 of the PBX 100. ing. A general fee management device or the like can be used as the controller 204, and a general billing adapter can be used as the MIF 120 to which the controller 204 is connected.

A plurality of mailboxes are set in the mail device 200. In particular, in the present embodiment, only information transmitted from a specific information source terminal to a specific information destination terminal used for information registration (recording) in a specific terminal is used. Various dedicated mailboxes such as dedicated mailboxes to be stored are set. Each of these dedicated mailboxes can register multiple messages, and can selectively delete specific ones of registered messages or forward them to other mailboxes It has become. The type of the dedicated mailbox and its details will be explained in each relevant part of the explanation below.
1- (3) Terminal Device Each terminal 300 is configured by juxtaposing a general multifunction telephone (hereinafter referred to as MFT) 302 and an operation / display device 304 formed as a separate unit. is there. The MFT 302 and the operation / display device 304 constituting one terminal are not connected to each other in the terminal, and they are connected to separate line circuits 104 of the PBX 100.

  The MFT 302 is used as a normal telephone as it is when the mail service is not used. When the mail service is used, the MFT 302 registers voice information and listens to reproduction information via the handset. The mail device is operated by the operation / display device 304. Therefore, the existing multi-function telephone can be used as it is without adding any special function to the MFT 302, which is advantageous in terms of reducing the cost of the system.

Since the MFT 302 and the operation / display device 304 are connected to the normal line circuit 114 of the PBX 100, a large number of terminals can be easily connected to the PBX 100. FIG. Only is shown. In a detailed description of the terminal and a specific example of operation, which will be described later, the terminal 300-1 including the MFT 302-1 and the operation / display device 304-1 is used by an officer L of a certain company. -2 and the operation / display device 304-2 are used by the manager A of the company, and a terminal 300-3 composed of the MFT 302-3 and the operation / display device 304-3. The explanation is made assuming that it is intended for use by the company's secretary.
2. Operation / Display (DSS)
As shown in FIGS. 2 to 4, the operation / display device 304 provided for each terminal 300 is combined with a large number of keys (push buttons) arranged in parallel on the upper surface of the case, and each of these keys. And a visual indicator (indicator lamp) 308 such as a light emitting diode. In addition, when each of these keys is pressed, the operation / display device 304 generates a PB signal corresponding to the key and representing a different code (that is, an identification code of the key) for each key. A PB signal generation circuit for sending to the PBX 100 is provided. In addition, each indicator lamp 308 can control ignition, extinguishing, blinking, and the like from the outside of the operation / display device 304.

  This type of function is equivalent to the function of a direct station selection device (DSS) widely used in ordinary telephone exchanges. Therefore, in this embodiment, DSS is used for the operation / display device 304. Therefore, hereinafter, the operation / display device 304 is referred to as DSS 304.

  According to the present embodiment, since a terminal can be configured by combining a general multi-function telephone as described above and a normal direct station selection device, in terms of further reducing the cost of the system. It is advantageous.

The use operation of the mail apparatus 200 is performed by operating the DSS 304 of each terminal 300. In this case, the central processing unit 106 of the PBX 100 determines the necessary line based on the PB signal of the key identification signal transmitted from the DSS 304. Connection, control of the mail apparatus 200, control of the indicator lamp of the DSS 304, and the like. This will be described in detail later.
2- (1) Function Assignment of DSS Key Next, three specific examples of function assignment of each key of the DSS 304 (hereinafter referred to as DSS key) will be described with reference to the DSS panel diagrams of FIGS.

  In order to easily understand the meaning of the function assignment of the DSS key, the following three points will be described in advance regarding the configuration of the present embodiment.

  The first point is that the function assignment of the DSS key is performed in the form of data setting in the storage device 108 of the PBX 100. As described above, the original function associated with each DSS key itself is that a PB signal representing the identification code of the key is transmitted to the PBX 100 by pressing the key. Then, the central processing unit 106 that has received this key identification code reads the function of the pressed DSS key (hereinafter referred to as the activation key) with reference to the storage device 108, and sends an operation corresponding to the read function by e-mail. The PBX 100 and the mail apparatus 200 are controlled so that the apparatus 200 can perform them. Therefore, a dedicated storage location for writing the function of each key of DSS of all terminals in this system is set in the storage device 108 (this will be described in more detail later). . The actual processing is performed by the central processing unit 106 as described above, but in the description of the function assignment of the DSS key described below, each key will be described in relation to the function obtained as a result of the depression.

  The second point is that DSS keys can be grouped according to their function. That is, (1) a mail operation key for designating various operations (recording, playback, erasure, etc.) to be performed by the mail device, (2) designation of a mail destination terminal when registering mail information, and mail A terminal designation key for designating a mail source terminal when reproducing information, and (3) various other operations such as connection and disconnection between the MFT of the terminal and the mail device, for example. It is roughly divided into keys for causing the PBX 100 to perform. The terminal designation key is further subdivided into a single destination designation key during registration, a multiple destination designation key during registration, a source designation key during reproduction, and the like.

  Details of these groupings will be described later with reference to FIG.

  The third point is that, as described above, a dedicated mailbox that is used to store only mail information from a specific source terminal to a specific destination terminal is set in the mail device 200. That is. Since each of these dedicated mailboxes corresponds to a specific combination of a source terminal and a destination terminal, when there are m callable terminals and n receivable terminals, at least m × n A dedicated box is set. Therefore, as an example, if a terminal designation key for designating another terminal Y as a mail destination is set on the DSS panel of a certain terminal X, the terminal X to the terminal Y are set in the mail apparatus 200. A dedicated box for information transmission is set, and a key for designating the terminal X as a transmission source exists in the DSS of the terminal Y. In the mail device 200, a mailbox corresponding to the priority of the mail information and a mailbox for recording and storage used for purposes other than information transmission are also set, which will be described in detail as needed. .

  The specific example of the function assignment of the keys in FIGS. 2 to 4 assumes a case where the system of the present embodiment is introduced into a company to which a considerable number of officers and general managers belong, for example. In this company, the progress of instructions from officers L to V, who tend to be absent from their own room, to directors A to K, and reports from directors A to K to those officers L to V smoothly Therefore, the system of the present embodiment is adopted in order to leave a message entered from outside when the officers L to V are absent as a message.

  In particular, FIG. 2 is a DSS panel diagram showing the function setting of the key of DSS 304-1 placed on the desk of officer L, and FIG. 3 is a DSS board diagram showing the function setting of the key of DSS 304-2 placed on the desk of Director A. FIG. 4 is a board diagram showing the function settings of the keys of the DSS 304-3 placed on the desk of the secretary who is mainly working on the outside line to the officers L to V.

All three types of DSS use the same hardware. That is, the DSS has 48 pushbutton-shaped keys on the upper surface of the case, and an indicator lamp 308 is combined with each of these keys. Characters are written on the upper surface of the keys to which the functions are assigned, and keys without characters are not treated as being registered in the storage device 108.
2- (2) First Example of Function Assignment of DSS Keys In FIG. 2, the DSS 304-1 on the desk of officer L is assigned function to 46 of its 48 keys. The keys can be divided into four groups and one special key according to their function, and these groups are shown surrounded by virtual lines 310, 312, 314, 316. “Mail call key” 318.

  In FIG. 2, the third group 314 from the top is the above-mentioned mail operation key, while the other groups 310, 312, and 316 are the above-mentioned terminal designation keys. A multiple destination designation key, group 312 is a single destination designation key during registration, and group 316 is a source designation key during reproduction.

  First, a “mail call key” 318 and seven mail operation keys (“record”, “confirm”, “delete”, “continue”, “play”, “save”, “end”) included in the group 314. Each key) will be described.

  The “mail call key” 318 is a key for calling the mail apparatus 200 from the terminal 300, that is, a key for connecting the MFT 302 of the terminal and the mail apparatus 200, and is first pressed when using e-mail. Key to be played.

  “Recording key” 320 is a key to be pressed when registering (recording) mail information in the mail apparatus. The “confirmation key” 322 is a key that is pressed when reproducing and confirming information registered in the mail apparatus. The “erase key” 324 is a key that is pressed when erasing information registered in the mail device. “Continue key” 326 is a key to be pressed when another service is to be performed after the mail apparatus is operated to perform a certain service. A “reproduction key” 328 is a key that is pressed when reproducing and receiving mail information addressed to itself registered in the mail apparatus from another terminal. The “save key” 330 is a key that is pressed when the received mail information is transferred to the save mailbox and saved. The “end key” 332 is a key that is pressed when the use of the mail apparatus is ended.

  When any of the above seven mail operation keys is pressed, the central processing unit 106 responds to this by igniting the indicator light of the activation key and executing the function assigned to the activation key. The control signal is sent to the mail apparatus 200 in the form of a PB signal.

  Next, twelve registered multiple destination designation keys included in the group 310 will be described. These keys are used when the officer L sends the same mail information to a plurality of general managers. Among these, 11 keys excluding the “multi-destination key” 334 at the lower right in the virtual line block 310 are terminal designation keys corresponding to each of the 11 managers A to K who can be mail destinations. is there. The officer L presses the “multiple destination key” 334 after recording the message, that is, registering the mail information. Further, for example, if the registered mail address contains the department manager A, the user presses the key 310A labeled "department manager A", and further, all the department managers who are the mail recipients. The terminal designation keys corresponding to each of the above are pressed one after another.

  In response to any of the plurality of destination designation keys pressed during registration, the central processing unit 106 ignites the indicator light of the activation key in response to the activation and displays a predetermined key corresponding to the activation key. A PB signal is sent to the mail device 200.

  In particular, when the “multi-destination key” 334 is pressed, the central processing unit 106 uses the mailbox used for information registration (ie, message recording) performed by the officer L immediately before that (ie, recording of the officer L). A control command for transferring the contents of the dedicated mailbox) to another mailbox is sent to the mail apparatus 200 by a PB signal. Subsequently, each time the terminal designation key corresponding to each department manager is pressed, the central processing unit 106 identifies an identification number (box number) of a dedicated mailbox that stores only information addressed from the officer L to the department manager corresponding to the activation key. ) Is transmitted as a transfer destination box number by a PB signal. The mail device 200 transfers information according to the box number.

  Next, eleven registration-specific single destination designation keys included in the group 312 will be described. These keys are used when the officer L sends mail information to a specific general manager. Each of these 11 keys is a terminal designation key corresponding to each of 11 department managers who can be mail destinations. After recording the message, the officer L selects and presses the key corresponding to the head of the destination of the message. For example, if it is a department manager A, the key 312A marked with "section manager A" on the upper surface is pressed.

  In response to any of the eleven registration single destination designation keys described above being activated, the central processing unit 106 responds to this by illuminating the indicator light of the activation key and responding to the activation key. The predetermined PB signal is sent to the mail apparatus 200.

  The PB signal that is sent when the single address designation key at the time of registration is pressed will be described as follows, in particular, compared with the signal when the multiple address designation key is pressed at the time of registration.

  That is, for example, in the case of “director A key” 312A in the single destination designation key at the time of registration, the PB signal is transmitted when the “multiple destination key” 334 in the multiple destination designation key at the time of registration is pressed. And a signal sent when the “director A key” 310A among the multiple destination designation keys at the time of registration is pressed down is equal to a continuous signal. Therefore, regarding the PB signal to be sent, the operation of pressing one key 312A and the operation of pressing two keys 334 and 310A in succession are the same, but the function allocation example of FIG. The purpose of the single address designation key at the time of registration is to simplify the operation for using the mail apparatus as much as possible. Since the destination of the mail information is often single, it is actually greatly welcomed to be able to specify the destination with one touch.

  Next, the 15 playback source designation keys included in the group 316 will be described. These keys are the mail information registered in the other terminal (in this case, one of the terminals of the general manager A to the general manager K, or the terminal of the secretary described above) with the officer L as the destination. This is used to specify from which sender the registered mail information is to be reproduced when the “reproduction key” 328 is operated for reproduction and receipt. Of the 15 keys, the top four keys 316-1 to 316-4 are registered in the secretary terminal by giving priority to information and registering the mail information (this priority will be described in detail later). Is for receiving. Among them, the key 316-1 marked “priority 1” corresponds to a dedicated mailbox for the officer L and for storing only the highest priority mail information. Used to specify and replay mail information in it. Similarly, the other three keys 316-2 to 316-4 are associated with the mailboxes with the second to lowest (fourth) priority. The remaining 11 of the 15 keys are keys corresponding to the respective dedicated mailboxes that store only the mail information addressed to the officer L from each of the 11 general managers A to K. Used to specify each mailbox.

  The indicator lamp 308 combined with each of the above-mentioned playback source designation keys is blinked under the control of the central controller 106 when information is registered in the mailbox corresponding to the key. ing. In addition, when any one of these 15 source designation keys is pressed and activated, the central processing unit 106 responds to it by igniting the indicator light of the activation key and corresponding to the activation key. A predetermined PB signal is sent to the mail device 200.

  The officer L can recognize that there is mail information to be received and the sender of the mail information by the blinking of the indicator lamp of the sender designation key at the time of reproduction. In order to receive the mail information, the MFT 302-1 of the terminal is off-hooked, and the “mail call key” 318 of the DSS 304-1 of the terminal is pressed to connect the MFT 302 and the mail device 200. Let Next, by pressing the playback source designation key with the indicator light blinking, the mail information from the sender corresponding to the key registered in the mailbox corresponding to the key is reproduced. Ready (in this case, the indicator light of the pressed key changes from flashing to ignition). Then, by depressing the “playback key” 328, the mail information in the mailbox is reproduced and can be listened to with the handset of the MFT 302-1. At that time, if a plurality of pieces of mail information are registered in the mailbox, each time the “playback key” 328 is pressed, the pieces of mail information are reproduced one by one.

The description of the function assignment of the DSS key for the DSS 304-1 of the officer L's terminal 300-1 in FIG. As described above, since the function assignment of the DSS key is set by the data in the storage device 108, the change of the function assignment is arbitrary and easy.
2- (3) Second Example of DSS Key Function Assignment The function assignment in DSS 304-2 used by Director A shown in FIG. 3 is basically the same as that in DSS 304-1 of officer L in FIG. There are only minor differences. Therefore, in DSS 304-2 in FIG. 3, the same or corresponding parts as DSS 304-1 in FIG. 2 are denoted by the same reference numerals, and detailed description thereof is omitted. Will be described.

  In DSS 304-2 in FIG. 3, the recipients who exchange the mail information are officer L to officer V. Therefore, the keys corresponding to the keys A to K in DSS 304-1 in FIG. Here, the officers L to V are written. However, this is not an essential difference, only the name of the other party is different.

  In addition, a “mail call key” 318, a group 310 of multiple address designation keys at the time of registration, a group 312 of single address designation keys at the time of registration, and a group 314 of mail operation keys are also the manager of this DSS, The communication counterpart is the same as that of FIG.

  The substantial difference is that the “priority keys” 316-1 to 316-4 provided in the DSS 304-1 in FIG. It is not done. This is because the secretary uses only the officer to relay the message from the outside line with the mail device, so those keys are not required for the terminal for the manager.

The usage of each DSS 304-2 key is the same as that described with reference to FIG.
2- (4) Third Example of DSS Key Function Allocation The DSS 304-3 key function allocation used by the secretary shown in FIG. 4 is considerably different from the DSS of FIG. 2 and FIG. This is because in the case of a secretary, there is a special situation in which the DSS 304-3 is used to register messages from the outside line to the officers L to V in the mail device.

  In FIG. 4, the DSS 304-3 placed on the secretary's desk is assigned a function to 23 of its 48 keys, and these 23 keys are divided into 3 groups and 3 special keys according to their functions. And can be divided into The first of these groups is a group of destination designation keys at the time of registration, and is represented by being surrounded by a virtual line 338 in the drawing. The second group is a group of priority assignment keys, which are represented by being surrounded by a virtual line 340. The third group is a group of mail operation keys, and this group is represented by being surrounded by a virtual line 314 corresponding to FIG. 2 and FIG. The three special keys are “mail call key” 318, “automatic recording key” 342, and “end call key” 344.

  First, the group 314 includes five mail operation keys (“recording key” 320, “confirmation key” 322, “erase key” 324, “playback key” 328, and “end key” 332). Each of these keys performs the same function as the key of the same name provided in the DSS 304-1 in FIG. Further, unlike the DSS of FIG. 2, the secretary DSS 304-3 is not provided with a “continuation key” and a “save key”.

  The group 338 of address designation keys at the time of registration includes eleven keys. These keys have the destination name written on the upper surface of the key 338, and the single address designation at the time of registration of the DSS 304-2 of the executive A in FIG. It is the same as that of the key. This is also the same in terms of function, and is a key that can designate a dedicated mailbox corresponding to the destination. However, the registration designation destination designation key 338 in the secretary DSS 304-3 is displayed after the key is pressed. Subsequently, the designated mailbox is determined only when one of the four priority assignment keys 340 is pressed.

  In other words, email information addressed to one of the officers that the secretary has taken over is stored in a dedicated mailbox that is set up for a specific combination of the destination officer and the priority of the email information. This information priority is given to the mail information by the secretary who relays the information, after judging the contents and properties of the information individually and pressing any priority assignment key. It is like that.

  The priority assigning key group 340 includes four keys 340-1 to 340-4, and by pressing the key 340-1 marked “Priority 1” among them, the key 340-1 is preceded. The highest priority is given to the registered mail information. Similarly, the other three keys 340-2 to 340-4 are used to give priority from the second to the lowest (fourth) to the mail information.

  When any of the mail operation key, registration destination designation key, and priority assignment key described above is pressed, the central processing unit 106 displays the pressed key in response thereto. While lighting the lamp, a predetermined signal corresponding to the pressed key is sent to the mail apparatus 200 in the form of a PB signal.

  Of the three special keys provided in the secretary DSS 304-3, the “mail call key” 318 has the same function as the key of the same name described with respect to the DSS 304-1 for the officer L in FIG. , Used to call the mail device 200 and connect to the secretary terminal MFT302-3. The “automatic recording key” 342 is also a key for calling the mail apparatus 200. However, this key 342 is used when the secretary is talking to the other party using the MFT 302-3 and is in the state of talking. This key is used to set a three-way communication state between the secretary, the other party, and the mail device 200 for recording and recording. When this “automatic recording key” 342 is pressed, the central processing unit 106 responds to this by igniting the indicator lamp 308 of this key 342 and sending a predetermined signal to the mail apparatus 200 in the form of a PB signal. . The indicator lamp 308 of the “automatic recording key” 342 is kept in an ignition state while the three-party call state continues. The “end call key” 344 is a key used to release the office line (call partner) from the three-party call state when the three-party call recording service is terminated. When this “end key” 344 is pressed, the central processing unit 106 responds by igniting the indicator lamp 308 of this key 344 and a predetermined signal corresponding to this key 344 in the form of a PB signal. Send to mail device 200.

This is the end of the description of the function assignment of the DSS key of the secretary DSS 304-3. Note that the secretary DSS 304-3 can be changed in various ways and easily as in other DSSs.
3. Registration Data in Storage Device Next, data registered or stored in the storage device 108 of the PBX 100 will be described.

  The storage device 108 stores all the data necessary for the operation of the central controller 106. However, here, the data relating to the operation as a normal private branch exchange is not described, and the present invention is not particularly limited. Only relevant data will be described.

  5 to 9 are diagrams showing various data registration memory areas in the storage device 108. Before describing various data settings with reference to these drawings, the terms “key number” and “DSS number” will be described.

  As described above, each DSS 304 has 48 keys. A number assigned to each key in order to distinguish and identify these 48 keys in one DSS is a “key number”. For example, a serial number from 1 to 48 may be used. In addition, in order to distinguish and identify all the DSSs 304 used in the system, the numbers assigned to the respective DSSs are “DSS numbers”, which are also consecutive numbers corresponding to the total number of DSSs. good.

If a DSS key in the system is pressed (ie, activated) and a PB signal corresponding to that key is sent to the PBX 100, the central processing unit 106 is based on the received contents of the PBX signal. The key number of the activation key can be determined, and the DSS number of the DSS (activation DSS) where the key is pressed is identified by identifying the line circuit 114 from which the PB signal has arrived. be able to. By combining “DSS number” and “key number”, all DSS keys in the system can be specified individually, so the activation key is specified from the DSS number and key number determined in this way. can do. 3- (1) Key Information and Key Type FIG. 5 shows a memory area 510 for registering key information of each DSS key for each individual key in the system. The area is referred to as “DSSDATA”. In this DSSDATA 510, key information of each key is sequentially stored, and key information for one key is stored in a group of four consecutive storage positions as shown in the figure, and Necessary key information is searched using the DSS number and the key number.

  Of the four storage positions corresponding to one key, the type of the key is registered in the first half of the first storage position, and the portion consisting of the latter half of the storage position and the following three storage positions has Depending on the function, either accommodation position information (512) representing a specific accommodation position in the PBX 100 or dial information (514) representing a PB signal to be transmitted is registered as data contents.

  As shown in FIG. 5, the types of keys to be registered are divided into eight types.

  Type 0 is an unregistered key, and its contents are not registered.

  Type 1 is an extension call key (however, the key corresponding to this type is not set in the function assignment example of the DSS key shown in FIGS. 2 to 4), and is registered as the content of the call This is information on the accommodation position of the power extension.

  Type 2 is an auto-dial key (the key of this type is not set in the function allocation example of the DSS key described above), and what is registered as information is information indicating the dial number of the called party is there.

  The type 3 is a mail call key (318 in FIGS. 2 to 4), and information registered therein is information on the accommodation position of the extension that accommodates the mail device 200.

  Type 4 is a PB signal that designates an operation to be executed in the mail apparatus 200 from the central processing unit 106 to the mail apparatus 200 or a mailbox to be operated by pressing the key. Among the various keys that will be sent out, these are the remaining keys excluding the playback source designation key. In this case, prior to sending the PB signal, the indicator lamp associated with the pressed key is lit. Specifically, the keys corresponding to this type include a destination designation key for recording (including a single destination designation key for recording and a plurality of destination designation keys for recording), a “recording key” and a “playback key”. And various mail operation keys.

  Type 5 is a playback source designation key that is excluded in type 4. When this key is pressed, an indicator lamp combined with the pressed key is lit, and the central processing unit 106 is directed to the mail device 200. Then, a PB signal representing the box number of the mail box to be reproduced is sent. This key is distinguished from type 4 because the indicator lamp associated with this key must be blinked except when it is ignited when information is registered in the mailbox corresponding to the key. Because there is.

  Type 6 is an “automatic recording key” 342 (FIG. 4).

  The type 7 is “end call key” 344 (FIG. 4).

In addition, the keys registered in the types 4 to 7 are all registered as dial information representing the PB signal sent from the central processing unit 106 to the mail device 200. In particular, the recording destination designation is performed. For the key (type 4) and the reproduction source designation key (type 5), the dial information of the registered content represents the box number of the mailbox corresponding to the key.
3- (2) Flag indicating presence / absence of registration in box FIG. 6 shows whether or not mail information is currently registered in each mailbox set in the voice mail apparatus (VMS) 200. A memory area 520 for setting a flag to be displayed is shown, and this memory area is represented by “VMSFLG”. Within VMSFLG 520, each of all DSSs 304 used in the system is assigned 48 bits corresponding to the individual keys of that DSS. If the memory is in units of bytes, as shown in FIG. 6, 6 consecutive bytes can be allocated as a group to one DSS. In addition, it is convenient for searching if the allocation areas to the respective DSSs are arranged sequentially.

As described above, each information transmission mailbox set in the mail apparatus 200 has a unique destination, and the DSS of the destination terminal has a playback time corresponding to the mailbox. One source designation key is provided. Therefore, the presence / absence of registration information in a specific mailbox is represented by a flag of a bit in VMSFLG corresponding to the reproduction source designation key corresponding to the box provided in the DSS of the destination terminal of the box. It is. Then, when checking the corresponding flag, the corresponding allocation area is searched using the DSS number.
3- (3) Temporarily stored data Apart from data registered at the time of system setup, there is also data temporarily stored according to the operation of the system. FIGS. 7 to 9 show such data. The storage position of is shown.

  FIG. 7 shows that a “handover dial information” storage location 532 is provided in the work area (TEMBC) 530 for call processing.

  FIG. 8 shows an example of “starting DSS storage location information (starting DSS storage location in the PBX 100”) in a trunk memory (TRM) 540, which is a storage area of information for each individual trunk, which has been conventionally used in private branch exchanges. Information)) temporarily and a storage location 544 for temporarily storing “activation DSS key number information (key number of activation DSS key)”. Show.

  FIG. 9 shows that transmission dial information is temporarily stored in a register sender memory (RSM) 550 which is a dial processing memory conventionally used in a private branch exchange.

When the above information is registered, transferred, or read out will be described in detail in the following subroutine description.
4). Subroutine The operation of the system of the embodiment described above will be described below. The central processing unit 106 plays a central function in the operation of the system, and among the processes executed by the central processing unit 106, there are five subroutines that are executed particularly frequently. First, referring to FIG. 10, FIG. 11, FIG. 12 and FIG. 13, FIG. 14 and FIG. 15, and FIG. 16 and FIG. 17, and FIG. 18 and FIG. explain.
4- (1) Key Information Extraction Subroutine FIG. 10 is a flowchart of the process of the central processing unit 106 showing a “key information extraction subroutine”.

  When a certain DSS key provided in a certain DSS 304 in the system is pressed, the DSS is activated or the DSS key is activated. In this way, when a certain DSS 304 is activated, the line circuit 114 connected to that activation DSS 304 detects the depression of the DSS key, and the central processing unit 106 is notified that the key has been depressed and the key The key number is notified. Upon receiving this notification, the central processing unit 106 enters a “key information extraction subroutine”.

  Receiving the notification, the central processing unit 106 extracts the DSS number of the activation DSS with reference to the registration information about the line circuit 114 that has transmitted the notification, and the key number of the pressed DSS key from the notified content. Is extracted (step 580). Subsequently, DSSDATA 510 (FIG. 5) is searched based on the extracted DSS number and key number (step 582), and the key information of the pressed DSS key registered therein (ie, the key) is searched. The type and the registered content (accommodating location information or dial information) are extracted (step 584). When the above is completed, the processing by the central processing unit 106 exits from this subroutine and returns.

This “key information extraction subroutine” is a subroutine that is executed whenever any key of any DSS in the system is pressed.
4- (2) PB Sending Subroutine FIG. 11 is a flowchart of the processing of the central processing unit 106 showing the “PB sending subroutine”.

  The above-mentioned “key information extraction subroutine” is executed in response to the depression of the DSS key, and the activation DSS key is a key corresponding to one of types 4 or 5 from the key information obtained thereby. If found, the processing of the central processing unit 106 enters either the “PB sending subroutine” or the “PB sending key pressing subroutine during PB sending” described below.

  When a key corresponding to either type 4 or 5 is pressed, a PB signal is always sent from the central processing unit 106 to the mail device 200. Therefore, a type 4 DSS key and a type 5 DSS key are sent. In the following, the key type name “PB transmission key” will be used.

  Which of the above two subroutines is entered is determined as follows. That is, before a PB signal transmission from the central processing unit 106 to the mail apparatus 200 started in response to a certain PB transmission key is pressed, that is, during the transmission of the PB signal, another one is sent. When the PB transmission key is pressed, the process enters the “PB transmission key pressing subroutine during PB transmission”. On the other hand, when the PB transmission key is not transmitted, a certain PB transmission key is pressed. The process enters the “PB sending subroutine”.

  These two types of subroutines have the same purpose. That is, when any of the PB send keys is pressed, the indicator lamp associated with the pressed PB send key is lit and a predetermined PB signal corresponding to the pressed key is set to the center. It is intended to be sent from the processing device 106 to the mail device 200.

  Therefore, the central processing unit 106 determines that the activation DSS key is PB from the key type of the key information of the activation DSS key extracted in the “key information extraction subroutine” executed in response to activation of a certain DSS key. If the transmission key is identified, and if the PB signal is not being transmitted at that time, the "PB transmission subroutine" is entered.

  As shown in FIG. 11, when this subroutine is entered, the central processing unit 106 dial information (PB transmission key is a type 4 or type 5 key) which is the registered content of the key information extracted immediately before. Therefore, the dial information includes the box number of the mailbox corresponding to the key), and is transferred to the takeover dial information area 532 of the TEMBC 530 (FIG. 7) (step 586).

  Subsequently, the central processing unit 106 obtains the activation DSS accommodation position information and the activation DSS key number information from the activation DSS accommodation position information area 542 of the TRM 540 (FIG. 8) corresponding to the MFT provided in the same terminal as the activation DSS. Are saved in the activation DSS key number information area 544 (step 588).

Subsequently, the central processing unit 106 ignites the indicator lamp of the activation key based on the activation DSS accommodation position information and activation DSS key number information saved in the TRM 540 (step 590), and then the takeover dial of the TEMBC 530 first. The transfer dial information transferred and registered in the information area 532 is transferred to the transmission dial information area 552 of the register sender memory (RSM) 550 (FIG. 9) (step 592), and transferred to and stored in the RSM 550. The contents of the transmitted dial information are transmitted to the mail apparatus (VMS) 200 by a PB signal (step 594). When the above is completed, the processing exits from this “PB sending subroutine” and returns.
4- (3) PB Sending Key Pressing Subroutine During PB Sending FIGS. 12 and 13 are flowcharts of the processing of the central processing unit 106 showing the “PB sending key pressing subroutine during PB sending”.

  For example, in the second operation example of the system operation examples to be described later, after pressing the recording destination designation key, an operation of pressing the priority assignment key is performed continuously. In such a case, When the subsequent key is pressed, the PB signal is still being sent from the central processing unit 106 to the mail device 200 in accordance with the pressing of the previous key. The “PB sending key pressing subroutine during PB sending” is to cope with such a situation appropriately.

  If another DSS key is activated while sending a PB signal to the mail device 200 in response to the activation of a certain DSS key, the central processing unit 106 responds to this subsequent activation key with a “key”. "Information extraction subroutine" is executed. If it is identified from the key type in the key information of the subsequent activation DSS key extracted thereby that the subsequent activation DSS key is a PB transmission key, the “PB transmission key pressing subroutine during PB transmission” is performed. Enter.

  As shown in FIGS. 12 and 13, when this subroutine is entered, the central processing unit 106 calculates the total number of digits of the dial information which is the registration content of the key information of the subsequent activation DSS key extracted immediately before. (Step 802), and it is determined whether or not the dial information of the subsequent activation DSS key can be stored in addition to the dial information already registered in the transmission dial information area of the RSM 550 (FIG. 9). (Step 804) When the addition is possible, the dial information of the subsequent activation DSS key is transferred to the takeover dial information area of the TEMBC 530 (FIG. 7) (Step 806).

  Subsequently, the central processing unit 106 obtains the activation DSS accommodation position information and the activation DSS key number information regarding the subsequent activation DSS key in the TRM 540 (FIG. 8) corresponding to the MFT provided in the same terminal as the subsequent activation DSS. The activation DSS accommodation position information area 542 and the activation DSS key number information area 544 are saved (step 808).

  Subsequently, the central processing unit 106 ignites the indicator lamp of the subsequent activation DSS key based on the activation DSS accommodation position information and activation DSS key number information saved in the TRM 540 (step 810), and then Is added to the end of the transmission dial information registered in the transmission dial information area 552 of the register sender memory (RSM) 550 (FIG. 9). Then, the content of the transmission dial information of the RSM 550 is transmitted to the mail apparatus (VMS) 200 as a PB signal (step 814).

  If it is determined in step 804 that it is impossible to add further information to the transmission dial information of the RSM 550, the contents of the transmission dial information of the RSM 550 are once sent to the mail device 200 to the PB signal. PB signal transmission operation is performed (step 816), and the dial information corresponding to the number of dial digits that has been transmitted is deleted from the transmission dial information of the RSM 550 (step 818), and then again in step 804. Determine whether information can be added.

If transmission of all PB signals is completed, the process exits from this “PB transmission key pressing subroutine during PB transmission” and returns.
4- (4) PB Sending Completion Flashing / Fire Extinguishing Subroutine FIGS. 14 and 15 are flowcharts of the processing of the central processing unit 106 showing the “PB sending completion flashing / fire extinguishing subroutine”.

  As described above, when the type 4 or 5 DSS key is pressed to execute the “PB sending subroutine” or “PB sending key PB sending key pressing subroutine”, the indicator lamp combined with the starting DSS key is ignited. After that, an appropriate PB signal is sent to the mail apparatus 200. A subroutine for returning the previously ignited indicator lamp to the blinking state or the fire extinguishing state when the transmission of the PB signal is completed is the “flashing / fire extinguishing subroutine when PB sending is completed”.

  As shown in the figure, when the transmission of the PB signal from the central processing unit 106 to the mail device 200 is completed, the central processing unit 106 transfers the activation DSS accommodation location previously transferred to and stored in the TRM 540 (FIG. 8). Information is extracted (step 602), and a key number (search target key number) for specifying a key to be searched (search target key) in the work area of the storage device 108 is subsequently stored at a predetermined position. The minimum key number is set (step 604).

  The central processing unit 106 first searches DSSDATA (FIG. 5) for the key identified by the combination of the extracted activation DSS accommodation position information and the set search target key number, and checks the type of the key. The processing branches depending on whether or not the key is a processing target key (that is, a key of type 4 to type 5) whose indicator light is a target of flashing / fire extinguishing processing in this subroutine. (Step 606). If the search target key at that time is a key that does not belong to type 4 or 5 and is not a processing target key, the processing is skipped to step 616 described later, and the next key provided for the same activation DSS is skipped. In order to perform a search, the search target key number is incremented.

  On the other hand, if the search target key is a processing target key, it is further checked whether the search target key is a type 4 key or a type 5 key (step 608).

  As already described, the type 4 DSS key is a source designation key at the time of reproduction. Therefore, while the registration information exists in the dedicated mailbox corresponding to the key, the indicator lamp must be blinked. Therefore, if it is determined in step 608 that the search target key is type 4, the presence / absence of information in the corresponding mailbox is checked by checking the bit corresponding to that key in VMSFLG (FIG. 6). This is done by referring to the flag (step 610). If the information exists, the indicator light of the search target key blinks based on the activation DSS accommodation position information and the search target key number at that time. (Step 612).

  If it is determined in step 608 that the search target key belongs to type 5, the display light of the search target key is extinguished based on the activation DSS accommodation position information and the search target key number (step 614). .

  Further, in step 610, even if the search target key is a type 4 key, if it is determined that the registration information does not exist in the corresponding mailbox, the process similarly proceeds to step 614 to search for the search target key. The indicator light is extinguished.

From both step 612 and step 614, the process proceeds to step 616, where the central processing unit 106 increments the set search target key number. Subsequently, this incremented key number is the maximum DSS key number (for example, DSS has 48 keys as in this embodiment, and these keys are numbered consecutively from “1” to “48”. If it is, the maximum key number is “48”), and by searching for all keys provided in the activation DSS, the necessary processing is completed. (Step 618, if it is found that there is a key that has not been searched yet, the process returns to Step 606 to search for the next key, and all the keys are searched. If it is found that the necessary processing has been completed, the processing exits from this “flashing / fire extinguishing subroutine upon completion of PB transmission” and returns.
4- (5) Blinking / Release Fire Subroutine at Registration FIGS. 16 and 17 are flowcharts of the processing of the central processing unit 106 showing the “Blinking / Release Fire Subroutine at Registration”. FIG. 18 and FIG. 19 are sequence flow charts showing signal transmission of information registration / release notification, which is a condition for the processing of the central processing unit 106 to enter the “flashing at registration / fire-on-release subroutine”. is there.

  As described above, whether or not a message (information) is registered in each dedicated mailbox set in the mail device 200 is determined on the DSS on the message receiving side corresponding to the dedicated mailbox. It is displayed depending on whether the indicator of the transmission source designation key set during playback is flashing or extinguished. Therefore, when there is a change in the presence or absence of message registration, the state of the corresponding indicator lamp must be changed accordingly. Therefore, when a message is registered in a certain mailbox (when a message is registered), and when all the messages in a certain mailbox are retrieved and the box becomes empty (when a message is released) The subroutine for performing the indicator light control is this “flashing at registration / fire-out subroutine at release”.

  If either message registration or message cancellation is performed in the information storage unit 202, the controller 204 of the mail device 200 sends an “information registration / cancellation notification signal” to the central processing unit 106 via the interface circuit 120. To do. This signal notifies the registration / cancellation and the box number of the corresponding mailbox. When the central processing unit 106 receives this signal, it enters the “flashing at registration / fire-off subroutine at cancellation”. . The signal flow among the information storage unit 202 and controller 204 of the mail apparatus 200, the PBX 100, and the terminal 300 when the above notification is performed is shown in the sequence flow diagrams of FIGS.

  As shown in FIG. 16 and FIG. 17, when entering the “Blinking at registration / Fire extinguishing sub-routine”, the central processing unit 106 first determines whether registration or cancellation is performed from the received “information registration / release notification signal”. The mailbox number is read and the information is recorded in an appropriate storage location (step 634). These pieces of information are later referred to in steps 644 and 642, respectively.

  Subsequently, the central processing unit 106 sets the minimum DSS number at a predetermined position in the work area of the storage device 108 for setting a DSS number (search target DSS number) that specifies the search target DSS (step S100). 636) After that, the minimum key number is set at a predetermined position for setting the key number (search target key number) for designating the search target key (step 638).

  Next, the central processing unit 106 searches the DSSDATA 510 (FIG. 5) for the key (search target key) identified by the combination of the search target DSS number and the search target key number thus set, and checks the type of the key. Then, in this flashing at the time of registration / flashing at the time of cancellation, the process branches depending on whether or not the indicator lamp is a key to be processed (that is, a type 5 reproduction source designation key). (Step 640). If the search target key is not type 5, that is, a key that is not a processing target, the processing is skipped until step 650 described later, and the search is performed to search for the next key of the search target DSS. Increment the target key number.

  On the other hand, if it is determined in step 640 that the search target key is a processing target key, the mailbox number corresponding to the search target key is further read from DSSDATA 510 and the reception previously stored in step 634 is received. The mailbox number in the signal is checked against whether or not they match (step 642). If they do not match, the process is skipped to step 650.

  If the mailbox numbers match, the mailbox previously notified by the information registration / cancellation notification signal from the controller 204 of the mail device 200 is used as the search source designation key at the time of reproduction that is the search target at this time. It turns out that it was a corresponding mailbox. Therefore, after checking whether the previously received signal is a message registration notification or a message release notification (step 644), if it is a registration notification, it is set at this time. Based on the search target DSS number and the search target key number, the indicator light of the key flashes (step 646), and if it is a release notification, the key is based on those numbers. Is extinguished (step 648).

  If the indicator lamp is controlled as described above, the process proceeds to step 650. As described above, in this step, the central processing unit 106 increments the set search target key number. Subsequently, by checking whether or not the incremented key number has exceeded the DSS maximum key number (step 652), it is necessary to search for all the DSS keys that are the search target at that time. It is determined whether or not the process is finished. If it is determined that there is a key that has not been searched yet, the process returns to step 640 to search for the next key of the same DSS. On the other hand, if it is found that the necessary indicator lamp processing has been completed for all the keys of the DSS, the process proceeds to step 654, where the central processing unit 106 increments the set search target DSS number. Subsequently, by checking whether or not the incremented DSS number exceeds the maximum DSS number in this system (step 656), all the DSSs in the system are searched and necessary processing is completed. It is determined whether or not. If it is found that there is a DSS that has not been searched yet, the process returns to step 638, the search target key number is set to the minimum value again, and the DSS provided in the DSS of the next terminal is provided. If the key search is started and it is found that the necessary processing for the DSS of all the terminals in the system has been completed, the processing of the central processing unit 106 performs this “flashing on registration / fire on release” subroutine. Exit and return.

This is the end of the description of the five frequently used subroutines related to the processing executed by the central processing unit 106.
5). Specific Operation Example Next, the operation of the system in the following three cases will be described as an example of the specific operation of the system according to the embodiment described above.
(1) System operation examples when the officer L operates his / her terminal to register a message addressed to the manager A in the mail device (FIGS. 20, 21, 22, and 23). This operation example shows an example of a registration operation for exchanging mail information between ordinary terminals (officers or general managers' terminals) excluding the secretary's terminal.
(2) Example of system operation when a secretary who receives a call from the outside instead of the officer L registers the message to the officer L in the mail device when an outside call is made to the officer L who is not in the room ( 22 and 23, 24, 25, 26 and 27).
(3) System operation example when manager A reproduces and retrieves mail information from officer L registered for himself (FIGS. 28 and 29).
5- (1) First Operation Example FIGS. 20, 21, 22 and 23 show an example of system operation when the officer L registers a message addressed to the general manager A in the mail device. FIG. FIG. 21 is a sequence flow diagram of a connection procedure between the PBX 100, the mail device 200, and the terminal 300, and FIGS. 22 and 23 are diagrams in the system. It is a state chart showing the connection state between each element.

  Since the main processing executed by the central processing unit 106 when this system operation is performed is a combination of subroutines already described, the flowchart of the central processing unit 106 is omitted. In the following description, the description will be made in the form of a reference to those subroutines.

  In the following description, quotes with “M” at the beginning are those in FIG. 20, quotes with “P” at the beginning are those in FIG. 21, and quotes with “S” in the beginning are FIG. 22 and FIG.

  In order to register the message, the officer L first off-hooks the MFT 302-1 of his / her terminal 300-1 (M10, P100, S120), and then the DSS 304-1 placed next to the MFT 302-1. “Mail call key” (318 / FIG. 2) is pressed (M12, P104).

  Then, the line circuit 114 connected to the DSS 304 of the officer L detects this key press and notifies the central processing unit 106 of the key press and the key number. Upon receiving the notification, the central processing unit 106 executes the “key information extraction subroutine” described above, and the pressed key (in this case, the central processing unit 106 still determines that the pressed key is the “mail call key”). Key information (key type and registered contents thereof) is extracted.

  The central processing unit 106 identifies that the pressed key is the “mail call key” from the extracted key type information, and, according to the mail device accommodation position information that is the registered content of this key information, The mail device 200 is called (P106, S121).

  The mail apparatus 200 automatically responds to this call (P108), and this response is detected by the line circuit 114 connected to the information storage unit 202 of the mail apparatus 200, and the detection of the response is detected by the central processing unit. 106 is notified. Receiving the notification, the central processing unit 106 sets a communication path between the MFT 302-1 and the mail device 200 in which the officer L is off-hook (S122).

  If the telephone device L enters the communication state with the mail apparatus 200, the officer L depresses the “recording key” (320 / FIG. 2) of the DSS 304-1 (M14, P110).

  Then, the line circuit 114 connected to the DSS 304-1 of the officer L detects it and notifies the central processing unit 106 of the key press and the key number. Enter information extraction subroutine.

  The central processing unit 106 identifies from the key information obtained by executing this “key information extraction subroutine” that the type of the pressed key corresponds to the above-described type 4, and subsequently, the “PB transmission subroutine” Enter. In this case, by executing this “PB sending subroutine”, the indicator lamp 308 of the “recording key” 320 is lit, and the registered content of the key information of this “recording key” 320 is transferred from the central processing unit 106 to the mail device 200. It is transmitted as a PB signal (P112, P123). The registered contents of the “recording key” sent here are a service number for instructing the mail apparatus 200 to perform a recording operation, and a box number of a dedicated mailbox used when the officer L performs recording. This is dial information representing

  When the central processing unit 106 completes sending the PB signal to the mail device 200, the central processing unit 106 enters a “flashing / fire extinguishing subroutine upon completion of PB sending”. In this case, by executing this subroutine, the indicator lamp 308 of the “recording key” 320 is extinguished.

  The mail apparatus 200 that has received the box number of the dedicated mailbox for recording of the officer L by the PB signal opens the mailbox and starts the recording operation (S122). At the start, a recordable sound is sent from the mail device 200 to the PBX 100 (P114), and this recordable sound is further sent to the MFT 320-1 of the officer L terminal. When the officer L hears this recordable sound through the handset of the MFT 302-1, recording starts (M16).

  The officer L who has finished the recording designates the destination by pressing a key corresponding to the destination to which the recorded information is to be sent among the “destination designation key for recording” of the DSS 304-1. Here, since the information is sent to only the general manager A, the officer L presses the “director A key” 312A (FIG. 2) in the group 312 of the single address designation key at the time of recording (M18, P116).

  Then, the line circuit 114 connected to the DSS 304-1 of the officer L detects it and notifies the central processing unit 106 of the key press and the key number. Enter information extraction subroutine.

  The central processing unit 106 identifies from the key information obtained by executing this “key information extraction subroutine” that the type of the pressed key corresponds to the above-described type 4, and subsequently, the “PB transmission subroutine” Enter. In this case, by executing this “PB sending subroutine”, the indicator lamp 308 of the “manager A key” 312A is lit, and the registration information of the key information of this “manager A key” 312A is sent from the central processing unit 106 to the mail. A PB signal is sent to the apparatus 200 (P118, S123). The registration content corresponding to the “director A key” 312A sent at this time includes a service number indicating that the officer L should execute a transfer service for transferring information recorded in his / her own box to another box, and This is dial information indicating a box number of a dedicated box for sending a message from the officer L to the general manager A to be a transfer destination.

  The central processing unit 106 enters the “flashing / fire extinguishing subroutine when PB transmission is completed” when the above PB signal has been transmitted to the mail apparatus 200. In this case, the execution of this subroutine causes the indicator lamp 308 of the “director A key” 312A. Is destroyed.

  On the other hand, the mail apparatus 200 that has received this PB signal from the central processing unit 106 forwards the information in the dedicated box for the officer L to the dedicated box for registering information from the officer L to the general manager A according to the content of the signal. Later, it waits for reception of a service number designating a service to be executed next (S122).

  Next, the officer L presses the “end key” 332 of his / her DSS 304-1 (M20, P120), and on-hooks the MFT 302-1 (M22).

  Then, the line circuit 114 connected to the DSS 304-1 detects this key press and notifies the central processing unit 106 of the key press and the key number. Enter the key information extraction subroutine.

  The central processing unit 106 identifies that the type of the pressed key is the above-described type 4 from the key information obtained by executing this “key information extraction subroutine”, and enters the “PB transmission subroutine”. In this case, by executing this “PB sending subroutine”, the indicator lamp 308 of the “end key” 332 is lit, and the registered content of the key information of this “end key” 332 is transferred from the central processing unit 106 to the mail device 200. It is transmitted as a PB signal (P122, S123). The registered content corresponding to the “end key” sent at this time is dial information representing a kind of service number for notifying the mail device 200 of the end of the service.

  The central processing unit 106 enters the “flashing / fire extinguishing subroutine when PB transmission is completed” when the above PB signal has been transmitted to the mail apparatus 200. In this case, the execution of this subroutine causes the indicator lamp 308 of the “end key” 332 to be displayed. Is destroyed.

  On the other hand, the mail apparatus 200 that has received the PB signal corresponding to the “end key” from the central processing unit 106 automatically performs an on-hook operation and ends the call (P128). The on-hook of the mail device 200 is detected by the line circuit 114 connected to the information storage unit 202 of the mail device 200 and notified to the central processing unit 106. The communication path between the MFT 302-1 and the mail device 200 is released and the call is terminated.

  By the operation so far, the information from the officer L to the general manager A is registered in the mail device 200.

  Thereafter, the “flashing at registration / fire-off subroutine at the time of cancellation” (FIGS. 16, 17, 18 and 19 is executed. That is, first, the information storage unit in the mail device 200 is executed. The controller 202 notifies the controller 204 of information registration and the box number of the registered mailbox (in this case, a dedicated box from the officer L to the general manager A). 204 sends the “information registration / cancellation notification signal” to the central processing unit 106 via the interface circuit 120 to notify the central processing unit 106 of the registration of this information and its box number. The central processing unit 106 enters the “flashing at registration / fire-off subroutine at release.” In this operation example, the officer who registered the information The reproduction source designation key corresponding to the dedicated box from the manager to the department A is included in the group 316 of reproduction origin designation keys in the DSS 304-2 (FIG. 3) of the department A terminal that is the information receiving side. “Executive L Key” 316L In this case, therefore, by executing this “Blinking / Registration Fire Subroutine”, the DSL “Executive L Key” 316L indicator lamp 308 of the terminal of the general manager A is blinked. It becomes like this.

  Therefore, the manager A can easily know that the message from the officer L is registered by simply looking at the indicator lamp 308 of the “officer L key” 316L.

This is the end of the description of the system operation example when the officer L registers the message addressed to the general manager A in the mail apparatus.
5- (2) Second operation example FIGS. 22, 23, 24, 25, 26, and 27 show the case where an officer L calls an officer L who is not in the room. Instead, the secretary who receives the call shows an example of the system operation when the message to the officer L is registered in the mail device.

  As already described, FIG. 22 and FIG. 23 are state charts showing the connection state between each element in the system. FIG. 24 is an operation procedure diagram showing an operation performed by the operator (secretary) and a DSS key to be pressed, FIG. 25 is a sequence flow diagram of a connection procedure between the PBX 100, the mail device 200, and the terminal 300, and FIG. 27 and FIG. 27, when this system operation is performed, the central processing unit 106 executes from when the “automatic recording key” is pressed until the three-party call is terminated and the control of the indicator light is performed. It is a flowchart of a process.

  In the following description, quotes with “M” at the beginning are those in FIG. 24, quotes with “P” at the beginning are those in FIG. 25, and quotes with “S” in the beginning are The reference numerals in FIGS. 22 and 23, and the reference numerals beginning with numerals in parentheses are those in FIGS.

  In order to perform the system operation of the second specific example, first, there is an incoming call from the telephone 406 connected to the public network 404, which is detected by the office trunk 118 and notified to the central processing unit 106. The device 106 notifies the relay console 402 of the incoming call from the station line through the relay console control device 116, and when the relay console 402 receives the notification, the operator of the relay console 402 and the caller of the telephone 406 communicate with each other. A call is made between the two. Then, the operator of the relay stand 402 transfers this incoming call to the MFT 302-3 of the secretary terminal 300-3.

  With the above procedure, a local line call between the secretary MFT 302-3 and the telephone 406, indicated by M30 in FIG. The secretary then operates the DSS 304-3 (FIG. 4) of his / her terminal as follows to register the contents of the local line call in the mail apparatus 200 as message information to the officer L.

  That is, first, the secretary presses the “automatic recording key” 342 of the DSS 304-3 of his / her terminal (M32, P130) while talking on his / her MFT 302-3 (S124).

  Then, the line circuit 114 connected to the DSS 304-3 detects this, and notifies the central processing unit 106 of the key press and the key number. ”Is entered (690).

  The central processing unit 106 identifies that the pressed key is the “automatic recording key” 342 from the key type of the key information obtained by executing this “key information extraction subroutine”. The registration contents corresponding to the “automatic recording key” obtained together with the key type at this time are the extension number of the mail device 200, a kind of service number for instructing the mail device 200 to start recording, and the secretary terminal. The dial information represents the box number of the dedicated mailbox that is used only when information registration is performed by the above operation.

  The central processing unit 106 extracts the extension number of the mail device 200 from the information (692).

  Subsequently, the central processing unit 106 transmits the dial information other than the extension number of the mail device 200 to the takeover dial information area of the TEMBC 530 (FIG. 7) among the dial information representing the registration contents of the “automatic recording key”. Then, the activation DSS accommodation position information and the activation DSS key number information are transferred to the activation DSS accommodation position information area 542 and the activation DSS key of the TRM 540 (FIG. 8) corresponding to the secretary MFT302-3. Save in the number information area 544 (696).

  Next, based on the activation DSS accommodation position information and activation DSS key number information saved in the TRM 540, the central processing unit 106 displays the indicator 308 of the “automatic recording key” 342 of the secretary DSS 304-3 as the activation key. Is fired (698), the conference trunk (CFT) 122 for carrying out a three-party call is captured (700, P132), and the mail device 200 is based on the previously extracted extension number of the mail device 200. (702, P134, S125).

  The mail device 200 that receives the call automatically responds (P136), and the line circuit 114 that detects the response notifies the central processing unit 106 of the response (704).

  Upon receiving this notification, the central processing unit 106 transfers the takeover dial information previously transferred and registered to the TEMBC 530 (FIG. 7) to the transmission dial information area 552 of the RSM 550 (FIG. 9) (706). Then, the contents of the transmission dial information transferred to and registered in the RSM 550 are transmitted to the mail apparatus (VMS) 200 as a PB signal (708, P138, S126).

  When the central processing unit 106 completes the transmission of the PB signal, the CFT 122 is used for the three parties including the secretary MFT 302-3, the telephone 406 of the other party, and the mail device 200. Is set (710, S127).

  On the other hand, the mail device 200 opens the secretary's dedicated mailbox in accordance with the received PB signal, and starts a recording operation in a three-party call state. The secretary makes a three-way recording (M34), and when it is finished, presses the "end key" 344 (FIG. 4) of the DSS 304-3 (M36).

  Then, the line circuit 114 connected to the DSS 304-3 detects it and notifies the central processing unit 106 of the key press and the key number (712, P140). The “key information extraction subroutine” is entered (714).

  The central processing unit 106 identifies that the pressed key is the “end call key” 344 from the key type of the key information obtained by executing this “key information extraction subroutine”. Then, the indicator lamp 308 of the “end key” 344 of the DSS 304-3 is lit, and the CFT 122 is opened (P142) and the local trunk 118 (according to the contents of the key information of this “end key”) (accordingly) The telephone 406 is released (P144), thereby setting a communication path between the secretary MFT 302-3 and the mail device 200 (716, S122).

  Next, the central processing unit 106 enters a “flashing / fire extinguishing subroutine when PB transmission is completed” (718). In this case, by executing this subroutine, the indicator lamp 308 of the “automatic recording key” 342 that is ignited at the start of recording and the indicator lamp 308 of the “end call key” 344 that has just been ignited are both displayed. Fire extinguished. FIG. 26 and FIG. 27 show the flowcharts so far. The following processing is mainly a combination of subroutines, and thus the flowchart is omitted.

  When the above processing is completed, the secretary terminal MFT302-3 and the mail device 200 are in a two-party call state. In this state, the secretary records the three parties that have been recorded first as necessary. Recording of additional information such as supplementary comments regarding the inter-recording information is started (M38).

  When the secretary finishes this additional recording, he / she selects and presses the recording destination key corresponding to the destination to which the above three-party recording information and additional recording information are to be sent, and then makes his own judgment. Press the priority assignment key corresponding to the priority of the information. Here, it is assumed that the destination of the recording information is the officer L, and the secretary has determined that the highest priority should be given. Therefore, in this case, when the additional recording is completed, the secretary uses the “officer L key” 338L (FIG. 4) in the recording destination designation key group 338 set in the DSS 304-3 of his / her terminal. Pressed (M40), and subsequently, the "priority 1 key" 340-1 in the priority assignment key group 340 is pressed (M42).

  As described above, if the secretary presses one of the recording destination designation keys and one of the priority assignment keys set in his / her DSS 304-3 in succession and continuously presses the mailbox, Information transfer between them and control of the indicator light of the DSS key associated therewith are performed, and these processes are performed in the single address designation key 312 at the time of recording set in the officer DSS or the manager DSS described above. This is the same as when the button is pressed after recording the information.

  That is, if the secretary presses the “officer L key” 338L of the DSS 304-3 (P146), the line processing unit 114 connected to the DSS 304-3 detects it, and the central processing unit 106 “keys”. Enter the “information extraction subroutine”, and then enter the “PB transmission subroutine” according to the key information obtained by executing this “key information extraction subroutine”.

  In this case, by executing this “PB sending subroutine”, the indicator lamp 308 of the pressed “executive L key” 338L is ignited, and the registered content of the key information of this “executive L key” 338L is the central processing unit. The PB signal is sent from 106 to the mail apparatus 200 (P148). The registered contents of the key information corresponding to the “officer L key” sent at this time are the secretary's dedicated mailbox (that is, the three-party recording and additional recording described above used when the secretary performs recording). The mailbox of the dedicated mailbox used to send the information from the secretary to the specific officer who should be the forwarding destination, and the service number of the forwarding service that forwards the information in the used mailbox) to another box This is dial information representing a number.

  However, there are four dedicated mailboxes for one specific officer from the secretary, one for each of the four priority levels, and the box number for these four mailboxes is the last digit. Only are different from each other. The transfer destination box number registered in the key information of “Officer L Key” 338L illustrated above is the number of the part common to the four boxes corresponding to the officer L, excluding the last one digit number. It is. Then, the last one digit number necessary for determining one specific transfer destination box is registered as key information in each priority assignment key.

  Further, since the secretary continuously presses the “priority 1 key” 340-1 after pressing the “officer L key” 338L (P150), when the subsequent “priority 1 key” is pressed, The transmission of the PB signal from the central processing unit 106 to the mail apparatus 200 started in response to pressing of the “L key” has not yet been completed, and it is normal that the PB signal is being transmitted. If the PB signal is actually being sent, the processing of the central processing unit 106 enters the “PB send key PB send key pressing subroutine”. Otherwise, the process enters the “PB send subroutine”.

  As described above, when any of these subroutines is executed, the functions achieved as a result are the same. In other words, the pressed “priority 1 key” 340-1 indicator light is lit, and the registered content of the key information of this “priority 1 key” 340-1 is sent from the central processing unit 106 to the mail device 200 by a PB signal. It is sent out (P152). As described above, the registered content of the “priority 1 key” sent at this time is the last one digit of the box number of the information transfer destination box, so that the mail device 200 can execute the transfer service. You will receive all the information you need.

  The central processing unit 106 enters the “flashing / fire extinguishing subroutine when PB transmission is completed” when transmission of all the PB signals to the mail apparatus 200 is completed. In this case, the execution of this subroutine displays the “officer L key” 338L. Both the lamp 308 and the indicator lamp 308 of the “priority 1 key” 340-1 are extinguished.

  On the other hand, the mail apparatus 200 that has received all of the above PB signals from the central processing unit 106 sends the information registered in the secretary's dedicated box according to the contents of the signals to the officer L and has the highest priority. Transfer the information to a dedicated box for registering information.

  The secretary who has finished the key operation for information transfer subsequently presses the “end key” 332 of the DSS 304-3 (M44, P154), and on-hooks the MFT 302-3 (M46, P158).

  The processing executed by the central processing unit 106 in response to pressing of the “end key” 332 is as already described in the first operation example. That is, the indicator light 308 of the “end key” 332 is ignited, and the dial information indicating a kind of service number that informs the mail device 200 of the end of the service, which is the registered content of the key information of the “end key” 332, is sent to the mail. A PB signal is sent to the apparatus 200 (P156), and the indicator lamp 308 of the “end key” 332 is extinguished.

  On the other hand, the mail apparatus 200 that has received the PB signal corresponding to the “end key” from the central processing unit 106 automatically performs an on-hook operation and ends the call (P162). Further, the line circuit 114 connected to the information storage unit 202 of the mail device 200 detects the on-hook of the mail device 200 and notifies the central processing device 106, and the central processing device 106 that has received the notification is the secretary MFT 302. -3 and the mail device 200 are released to terminate the call.

  Through the operations so far, information for the officer L is registered in the mail device 200.

  Subsequently, as in the case of the first operation example described above, the registration of this information and its box number are notified from the controller 204 of the mail device 200 to the central processing unit 106, and the central processing unit 106 that has received the notification A group of reproduction source designation keys set in DSS 304-1 of officer L, which is a reproduction source designation key corresponding to the dedicated box with the highest priority for officer L that has been registered. The indicator lamp 308 of “priority 1 key” 316-1 in 316 is blinked.

This is the end of the description of the system operation example when the secretary who has received a call from the outside on behalf of the absent officer L registers the message to the officer L in the mail device.
5- (3) Third Operation Example FIGS. 28 and 29 show a system operation example when the manager A reproduces and retrieves mail information from the officer L registered for himself / herself, and FIG. 28 shows the operator. FIG. 25 is a sequence flow diagram of a connection procedure between the PBX 100, the mail device 200, and the terminal 300. FIG.

  Since the main processing executed by the central processing unit 106 when this system operation is performed is a combination of the subroutines already described, the flowchart regarding the processing of the central processing unit 106 is omitted here.

  In the following description, the reference signs with “M” at the head are those in FIG. 28, and the reference signs with “P” at the head are those in FIG.

  In the operation described below, the procedure when the central processing unit 106 ignites the pressed indicator light of the DSS key and the procedure when the ignited indicator light is extinguished again are the first to second steps described above. This is the same as that described in the operation example. Therefore, in the description of the third operation example, detailed description of those processing procedures is omitted for the sake of brevity.

  The PB signal transmission procedure when the pressed DSS key is a request for transmitting a PB signal from the central processing unit 106 to the mail apparatus 200 has also been described in the above other operation examples. The procedure is basically the same, and the main difference is the content of the PB signal to be transmitted and the operation of the mail apparatus 200 performed in response to the content. Therefore, in the following description, the difference will be mainly described.

  The listening operation (information receiving operation) shown as the third operation example is performed by the director A looking at the board surface of his / her DSS 304-2 (FIG. 3) to set the group 316 of the transmission source designation key during reproduction. This is a case where it is recognized that the information light is sent from the officer L by recognizing that the indicator lamp 308 of the “officer L key” 316L is blinking.

  In order to reproduce and listen to the information, the director A off-hooks the MFT 302-2 of his / her terminal (M50, P170), and subsequently, also sends the “mail call key” 318 of the DSS 304-2 of his / her terminal. Press (M52, P174).

  Then, the line circuit 114 connected to the DSS 304-2 detects pressing of this key, and thereafter, the central processing unit 106 calls the mail device 200 (P176) as in the first operation example (P176). A communication path between A's MFT 302-2 and the mail device 200 is set.

  When the manager A is in a conversation state with the mail apparatus 200 via the MFT 302-2, the “officer L key” in which the indicator lamp 308 is flashing on the surface of the DSS 304-2 as described above. 316L is pressed (M54, P180).

  Then, in response to this, the central processing unit 106 ignites the indicator lamp 308 of the “officer L key” 316L, and sends the registered content of the key information of this “officer L key” to the mail device 200 by a PB signal. (P182). The PB signal transmitted in this case is dial information representing a box number of a dedicated mailbox for registering information from the officer L to the general manager A.

  On the other hand, the mail device 200 sends a voice signal notifying the number of messages registered at that time in the mailbox designated by the PB signal to the PBX 100 (PIF84). The signal is sent from PBX 100 to Manager A's MFT 302-2, who listens to it.

  Next, the department manager A presses the “reproduction key” 328 in the mail operation key group 314 of his / her DSS 304-2 (M56, P186).

  Then, in response to this, the central processing unit 106 ignites the indicator lamp 308 of the “reproduction key” 328 and sends the registered content of the key information of this “reproduction key” to the mail apparatus 200 as a PB signal (P188). ). The PB signal sent in this case is dial information representing a service number that instructs the mail apparatus 200 to perform a reproduction operation.

  When the central processing unit 106 completes sending the PB signal to the mail device 200, the central processing unit 106 executes a “flashing / fire extinguishing subroutine upon completion of PB transmission” to perform control processing of the indicator lamp on the panel surface of the DSS 320-2. . In this case, the execution of this subroutine extinguishes the indicator lamp 308 of the “regeneration key” 328 that was lit just before, and the indicator lamp 308 of the “officer L key” 316L that was previously lit is flashing. It is returned to.

  The mail apparatus 200 that has received the PB signal corresponding to the “playback key” from the central processing unit 106 starts the playback operation of the registration information in the dedicated box addressed to the general manager A from the officer L. If multiple pieces of information are registered in this box (that is, if the officer L has registered a message to the general manager A more than once), the first registered message is played first. Is done. The director A listens to the reproduced information through the MFT 302-2 (M58).

  After listening to the playback information, if the “playback key” 328 is pressed again (M60), the second registered message can be played back and listened to. By repeatedly pressing the “playback key” 328, the registration information in this box can be played back one after another in the order of registration in the endless format.

  The director A may press the “save key” 330 of the DSS 340-2 when he / she wants to save the listened information. Then, a PB signal representing a service number for instructing a transfer service and a box number of a dedicated mail box for saving the general manager A is sent to the mail apparatus 200. As a result, the information is transferred and stored in the storage box of the manager A.

  In order for the general manager A to always accept a message from the officer L addressed to himself / herself, the fact that the message from the officer L has been newly registered can be easily recognized from the DSS indicator light. In order to do this, it is better to empty the mailbox after playing back and listening to the registration information. To do this, after listening to the information, the necessity of storing the information was judged, and if necessary, it was deleted from the registered box by transferring it to the storage box, and it was judged that it was not necessary. Then, by pressing the “erase key” 324, the information is simply erased from the registered box. This erasing operation is performed by sending a PB signal instructing the operation from the central processing unit 106 to the mail device 200, as in the case of other mail operation keys.

  If the above operation is performed for all the registration information in the dedicated box addressed to the general manager A from the officer L, this box becomes empty. If Director A knows that the box has been emptied when information is no longer reproduced even when the “replay key” 328 is pressed, or by voice notification from the mail device 200, The “end key” 332 is pressed (M62, P192) to end the call, and the MFT 302-2 is hooked (M64, P196).

  In response to pressing of the “end key” 332, the central processing unit 106 sends a PB signal notifying the end of the service to the mail device 200 (P194). The mail device 200 that has received the PB signal automatically performs an on-hook operation and ends the call. The central processing unit 106 is notified of the on-hook of the mail device 200 (P200), and the central processing unit 106 that has received the notification releases the communication path between the manager A's MFT 302-2 and the mail device 200.

  As a result of the above operation, one of the mailboxes of the mail apparatus 200 is newly emptied (that is, the information is canceled), and thereafter, the processing of the central processing unit 106 proceeds to the “flashing at registration / fired at cancellation” subroutine. Will enter.

  To do so, first, in the mail apparatus 200, there is a mailbox whose information has been released from the information storage unit 202 to the controller 204, and the box (here, a dedicated box from the officer L to the general manager A). The box number is notified. This notification is transmitted from the controller 204 to the central processing unit 106 via the interface circuit 120 by the “information registration / cancellation notification signal”. Upon receiving this notification, the central processing unit 106 “blinks / cancels upon registration / cancellation” Enter "Time-lapse fire subroutine". In this operation example, the playback source designation key corresponding to the box whose information has been canceled is the “officer L key” 316L (set in the DSS 304-2 of the department manager A terminal that is the information receiving side. FIG. 3). Therefore, in this case, the “flashing at registration / fire-off subroutine at release” is executed, so that the indicator lamp 308 of the “officer L key” 316L is extinguished.

  By this processing, the manager A can easily know when the information for himself / herself is newly registered from the officer L by seeing the indicator lamp 308 of the “officer L key” 316L blinking. be able to.

  This is the end of the description of the system operation example when the manager A reproduces and retrieves the message from the officer L registered for himself / herself.

  In the system of the embodiment described above, the terminal is equipped with a multi-function telephone and the mail device is a voice mail device. However, the system to which the present invention is applicable is of that type. It is not limited. That is, for example, the present invention can be applied to various systems such as a system in which a terminal is equipped with a facsimile apparatus and the like and a mail apparatus is a facsimile mail apparatus.

Industrial applicability
