, and an operation display section 47 consisting of a numeric keypad, a plurality of function keys, and a display capable of displaying multi-digit characters for an operator to operate the multi-function telephone terminal FTz.

When data is being exchanged using the modem 44, the network control device 44 prevents the output signal (audio signal) from the handset 42 from being output to the line (extension line).
1, and the network control device 41 is switched so that no data is input to the modem 44 when a call is being made by the handset 1-42.

In this case, the function keys of the operation display section 47 include a telephone directory key for calling the electronic telephone directory device BK, and a key for inputting a temporary telephone number, which will be described later, or setting presence/absence data in the electronic telephone directory device BK, for example. Electronic telephone directory device BK
Equipped with telephone directory operation keys, etc. for operating. Note that the telephone directory key is one of the speed dials, and extension numbers of groups corresponding to the communication control units CF1 to CFn are registered.

Now, the electronic telephone directory device BK manages personal destination information CD in the format shown in FIG.

This personal address information CD includes the person's personal name DN, the person's affiliation DO, telephone number (extension number in this case) TN, usable facsimile machine [7F Temporary telephone number TT that indicates the extension number (or external number) of the destination, presence/absence data SN1 that indicates whether you are at your seat or not, presence/absence data SN1 that indicates the time when you can receive the call, ringtone time AB, personal name MN, and, One (1) for each user consisting of the affiliated MO and using the extension of the private branch exchange PBX.
1 set) is formed and stored in the magnetic storage device 3. Note that data is read from the magnetic storage device 3 to the memory 2 as appropriate by cpul.

Here, the personal name DN and affiliation DO of the personal destination information CD.
is the character (kanji, kana,
(numbers, alphabets, symbols, etc.), and the personal name MN and affiliation MO are obtained by converting the alphabetic letters that form the basis of the name and department/division into numbers in the order shown below. Hereinafter, the former will be referred to as direct expression, and the latter will be referred to as indirect expression.

The indirect expression code information can be used as a button dial (for example, a multi-function telephone terminal F
An alphabet is assigned to each number on the numeric keypad (Tz to FTn), and the number string is coded when the alphabets forming the name in Roman letters are selected in that order.

In other words, for example, the surname "Furukawa" is rFURUKA.
It is written in Roman letters as WAJ, so if you follow the alphabet and number assignment method described above, it will be r38785292.
It is converted into a numeric string J, and this is stored as the personal name MN.

The personal name MN and affiliation MO in this indirect expression are fr
i-talk terminals DPz-DPn and PBt-PBn, multi-function telephone terminals FT1-FTn, and facsimile machine F
Xx-FXn is used as search information when using the functions of this electronic telephone directory device 8. In addition, the personal name DN and affiliation DO in direct expression are stored in the data processing device Pc.
t~PCn is this electronic telephone directory device! It is used as search information when using BK functions.

Of this personal address information CD, data other than the temporary telephone number TT and presence/absence data SN are stored on the administrator's terminal device V.
It is directly created (registered) in the electronic telephone directory device BK from T and cannot be updated or deleted unless a special password set in the system is input. Further, at the time of registration, the temporary telephone number TT field is set to an invalid state (for example, all digits are FF (hexadecimal)), and the presence/absence data SN is set to the "present" state. Note that the password may be set for each individual, and in that case, the user can arbitrarily update the personal destination information CD for himself/herself.

Furthermore, similar to the temporary telephone number TT for the telephone number TN, a temporary FAX number can also be set for the FAX number FN.

Note that the assignment relationship between letters and numbers for indirect expression is not limited to the above-mentioned relationship, and, for example, a row of 5 o sounds may be assigned to numbers. Further, as far as the personal name MN is concerned, an identification number assigned to each individual can be used.

With the above configuration, for example, from one of the multi-function telephone terminals FTz-FTn (in this case, from the multi-function telephone terminal FTI)
When making a call to a desired destination, the operator first inputs the destination's personal name in indirect expression using the numeric keys of the multifunction telephone terminal FTz, and then turns on the fti address book key.

As a result, the multifunction telephone terminal FTz is connected to the private branch exchange P
Bx and sends out the extension number corresponding to the group of 1 communication control unit CF1-CFn. In response, the private branch exchange device PBX selects one of the vacant communication control units CFx-CFn.
The multifunction telephone terminal FTL is connected to the communication control units CF1 to CFn.

When the connection with the communication control units CFx-CFn is completed, the multifunction telephone terminal FT1 switches the network control device 41 to the modem 44 side, and sends the indirect expression personal name inputted by the operator to a connection request command (predetermined code information). ) and then sent to the electronic telephone directory device 18K via the modem 44.

As a result, in the electronic telephone directory device 8, since the first communication control units CFl to CFn are used, it is possible to determine whether the other party is a multifunction telephone terminal FT1 to FTn or a facsimile device flFX.
1 to FXn, identifies the connection request command code included in the received data, and determines the data following it as an indirect expression of the personal name.

Then, a personal destination information CD in which a personal name MN in indirect expression that is the same as the transferred personal name in indirect expression is registered is searched from the magnetic storage device 3, and the personal destination information CD is read into the memory 2. Next, the read personal address information C
It is determined whether D's presence/absence data SN is set to the presence state, and if it is set to the presence state, it is further determined that the call can be received during the time slot indicated in the call-receivable time AB. judge whether

If the destination can receive calls, a personal destination information CD
It is determined whether valid data is stored in the temporary telephone number TT of the temporary telephone number TT, and if the temporary telephone number TT is valid, the temporary telephone number Ding T is stored, and if the temporary telephone number TT is invalid, the telephone number is stored. TN is read, and a command is given to the private branch exchange device 1PBX to connect the multifunction telephone terminal FT1 to the read temporary telephone number TT or telephone number TN. At the same time, the multifunction telephone terminal FTz is commanded to switch to the handset 42 side.

As a result, the private branch exchange device PBX is connected to the multi-function telephone terminal FT.
At the same time as the connection between I and the electronic telephone directory device BK is cut off, the multifunction telephone terminal FTr is temporarily put on hold, and the multifunction telephone terminal FTI is temporarily connected to a terminal device corresponding to the telephone number TT or the telephone number TN. In addition, multi-function telephone terminal FT
I is an electronic telephone directory device! Network control device according to instructions from BK! 41 to the handset 42 side,
This allows you to talk to a designated person.

Also, if the destination is unable to receive calls.

After the electronic telephone directory device BK notifies the multi-function telephone terminal FT1 that the call cannot be received, the electronic telephone directory device BK then
The line of the communication control unit CFt connected to the TI is disconnected. Also, at this time, the multifunction telephone terminal FTI displays on its display that the call cannot be received and disconnects the line.

In this case, the personal address information CD is searched only by the indirect expression of the personal name, but the operator is also required to input the indirect expression of the affiliation and search the personal address information CD by the indirect expression of the personal name and the affiliation. You can also do it like this.

In this way, it is possible to call the electronic telephone directory B from the multi-function telephone terminal FTI and connect it to the destination.

Further, as an operating procedure, it is also possible to first turn on the telephone directory key, connect to the electronic telephone directory device BK, and then input the name of the individual of the destination in indirect expression. In this case, electronic telephone directory device B
In K, since the multi-function telephone terminal FTI does not send predetermined data after connection, it can be determined that the operator has directly connected.

In addition, when using the functions of the electronic telephone directory device BK from any one of the telephone terminals DPI to DPn and PBt to PBn (for example, the telephone terminal FBI), the operator first selects the communication control unit CPt to CPn group from the telephone terminal FBI. Operate the extension number corresponding to the private branch exchange t! P.B.
Send to X. In response, the private branch exchange device PBK searches for one of the vacant communication control units CP1 to CPn and connects the telephone terminal PBt to the communication control units CP1 to CPn.

When the connection with the communication control units CPx-CPn is completed and the ringback tone is no longer heard, the operator inputs the name of the destination person in indirect expression.

Since the electronic telephone directory device BK is connected via one communication control unit CPx-CPn, one originating terminal device is the telephone terminal DP.
It is determined that it is either I to Pn or PBt to PBn, and the same process as described above is executed.

As a result, if the destination is in a state where calls can be received, the telephone terminal FBI is connected to the destination by the private branch exchange PBX.

Additionally, if the destination is unable to receive calls, the electronic phonebook device iBK sends a voice message such as "Unable to connect to the destination" to the voice synthesizer of the communication control units CP1-CPn connected to the telephone terminal FBI. 13 to notify the operator that the call cannot be received and disconnect one line. In this case, the usability will be further improved if a voice response is given to the operator explaining the reason why the call cannot be received.

Also, when using the functions of the electronic telephone directory device BK from facsimile devices FX1-FXn or data processing devices PCI-PCn, the same operations and processes as described above are performed, and either the destination is connected or a notification that the call cannot be received is notified. The line is disconnected. However, if a call can be received when a call is made from a facsimile machine F) h to FXn, the FAX number FN
Connect to the extension. At this time, if a temporary telephone number is set in the personal destination information CD and that temporary FAX number is valid, you may connect to the extension of that temporary FAX number, or the contents of the presence/absence data SN The fax number FN can be connected to the fax number FN regardless of the fax number FN, and information specifically specifying such a connection can be included.

Next, a case will be described in which the operator updates the personal destination information CD regarding himself/herself stored in the electronic telephone directory [BK].

For example, considering updating from the multi-function telephone terminal FTI as described above, the operator first turns on the telephone directory operation key and then turns on the telephone directory key.

Thereby, the multifunction telephone terminal FTz is connected to the electronic m-word width device B in the same manner as described above. and.

After confirming the connection with the electronic telephone directory device IIK, the multifunction telephone terminal FT1 connects the line to the modem 4 by the network control device 41.
4 side, electronic telephone directory device B via modem 44.
It sends a terminal command to K and thereafter operates as a terminal device for the electronic telephone directory device BK.

Electronic telephone directory device B
At the same time, the response data or echo back data from the electronic telephone directory device BK is displayed on the display. Note that when operating as a terminal device of the electronic telephone directory device BK in this manner, data exchange between the multifunction telephone terminal FTz and the electronic telephone directory device BK is performed via the modem 44.

When the terminal command is transferred from the multifunction telephone terminal FT1, the electronic telephone directory device BK first requests the operator to input the personal name in indirect expression, and when it is input, the input indirect expression Search the magnetic storage device 3 for the personal destination information CD in which the indirect expression personal name MN that is the same as the expressed personal name is registered, and store the personal destination information CD in the memory 2.
Read out.

At this time, it is also possible to request that the affiliation be input in indirect expression. Furthermore, when a password has been set for an individual, it is also possible to request the password to be input immediately after inputting the individual's name using indirect expression, and to display the operation menu only when the correct password is input. If the correct password is not entered at that time, the line may be disconnected at that point.

Then, for example, an operation menu such as "1. Change presence/absence 2. Temporary telephone number manual 3. Others 4. End" is displayed on the multifunction telephone terminal FTI, and the operator is prompted to select the desired operation.

Here, if the operator selects "1. Change presence/absence," the electronic telephone directory device BK first displays the currently set presence/absence data SN and asks the operator whether or not to change it. . On the other hand, when the operator inputs a change (for example, by turning on rlJ on the numeric keypad), the contents of the presence/absence data SH are changed and the result is displayed.

Furthermore, after confirming with the operator, the first operation menu is displayed. Also, at this time, presence/absence data SN is “
When the state is changed from "absent" to "present", the electronic telephone directory device t! Bk is the active temporary phone number T
Change T to invalid layer.

Also, if the operator r2. When "Temporary telephone number manual input" is selected, a temporary telephone number input mode is set, and the key data inputted by the operator using the operation keys is temporarily stored as a temporary telephone number, and the input data is echoed back. and.

When the operator notifies the completion of the temporary telephone number input, the data input so far is stored in the personal destination information CD as the temporary telephone number TT, and the first operation menu is displayed.

Normally, when the presence/absence data SN is changed from "present" to "r absent", this temporary telephone number is also input.

Note that the temporary telephone number may be a speed dial telephone number set in the multifunction telephone terminal FTL, or may be either an extension number or an external number.

Also, if you select "3. Others" in the operation menu.

A mode for changing the contents of other personal destination information CDs is selected, and the electronic telephone directory device BK first requests input of a password set in the system (or a password set for the individual).

If the correct password is entered here, electronic telephone directory device BK displays a submenu for selecting the item to be changed. When one item is selected from the submenu, the current settings for that item are displayed, the user is asked whether or not to change them, and if the item is to be changed, the process moves on to make the changes. When finished or if no changes are made, display the submenu.

This submenu includes an item for terminating the work in "3. Others", and upon completion, the first operation menu is displayed. Furthermore, if the correct password is not entered before the submenu is displayed, the display returns to the initial operation menu display state.

Then, when "4. End" is selected from the operation menu, the electronic telephone directory device BK ends this operation mode, returns the multifunction telephone terminal FTz to its original state, and disconnects the line at the same time. As a result, multi-function telephone terminal FT1
also disconnects the line and terminates operator operations.

Other operation menu contents include, for example, if the personal destination information CD includes a temporary fax number,
You can add an item to enter this temporary FAX number, and in that case, when the presence/absence data SN changes from the "absent" state to the "present" state, the temporary FAX number will be automatically
The number may be set to an invalid state. Further, as a matter of course, the operating procedure for updating the personal destination information CD is not limited to the one described above.

Similar processing is also performed when the contents of the personal destination information CD are updated by the facsimile machines FXz to FXn and the data processing devices 1lPct to F'Cn. Also.

When updating the contents of the personal destination information CD using the telephone terminals DPI to DPn and PBt to PBn, all the response data from the electronic telephone directory device BK is by voice, so the same operations as described above are performed. The system notifies the operator of the output and operation method using voice guidance, and prompts for input from the operator.

Although the deletion of the personal destination information CD can be done by each individual at their discretion, the deletion of the personal destination information CD can only be done by using the administrator terminal lVT as at the time of registration.
It may also be possible to erase the .
