Therefore, when the user requests the use of the Internet using the extension telephone 31, the user can know from the response (voice output) from the extension telephone 31 whether or not the Internet can be used. it can.

If all the contacts of the switch 17 are used for the request for the use of the Internet, the switch 17 cannot perform the connection process according to the request. Such an unusable state of the switching switch 17 is notified to the control operation unit 18A and the decoder unit 18C. In this case, the voice response unit 18B transmits a response to the use request and Then, a response to the effect that the Internet cannot be used is transmitted to the user via the extension telephone 31.

When the requester is notified that the Internet is not available, the voice response unit 18B further provides guidance (guidance) for setting when the Internet is unavailable to the extension telephone 3. It can be configured to communicate to the claimant through 1.

In this way, the user can make settings in the unusable state according to the response (guidance: guidance) from the voice response unit 18B. The setting in the unusable state is, for example, when the switch 17 changes from the unusable state to the usable state (the state of the switch 17 enables the connection processing according to the usage request). This is a setting that informs (notifies) the user when the Internet is available (ie, when the Internet becomes available). The notification to the user can be performed, for example, by calling the applicable extension telephone 31 with an availability notification (for example, ringing the corresponding extension telephone 31).

In this way, the user cannot use the Internet immediately In such a case, if the setting is made in an unusable state, then, when the Internet becomes available, the user knows that when the Internet becomes available, and issues a use request again, so that the Internet can be used. Can be used. According to the transmission control device 10 of the present invention, in a building such as a hotel or office where the PBX (a) is installed, the transmission control device 10 is connected to the PBX (a) and the subscriber line (extension line and office line). When the connection is established between both parties, the Internet can be used from an extension by simple connection work.

Just connect the transmission controller 10. For this reason, the Internet use environment can be prepared with only simple connection work.

Also, in each room, a configuration is adopted in which a voice signal and a data signal are branched using a splitter 33 and an ADSL modem 34 with respect to a telephone line (extension) already wired. For this reason, it is not necessary to construct a premise LAN using a router or the like, or to perform extensive wiring work.

The user connects the Internet device 32 to the modular jack for Internet connection among the modular jacks wired in each room, and the extension telephone number for Internet connection. Then, make a call according to the voice announcement instruction output from the extension 31 and the like. In this way, the Internet can be used from the user's room.

At this time, the Internet connection time can be set (if not set, the default time). If the connection time is set, excessive charges due to forgetting to disconnect the connection can be prevented.

Also, since only the data signal is connected to the extension via the transmission control device 10 according to the present invention and the office line, and the voice signal is connected to the extension via the PBX (a), the user is connected to the Internet. Even when using a telephone, the extension can be used as before. By using the transmission control device 10 according to the present invention, all data signals pass through the transmission control device 10 and only audio signals pass through the PBX (a). There is no need to add or change important functions or to develop a new exchange to replace the PBX (a). Further, as described above, the cost can be reduced in terms of adding new equipment and wiring work.

《Operation example 1》

As an operation example 1, an operation example in which a user in each room operates the transmission control device 10 using the extension telephone 31 and uses the Internet will be described. 4 and 5 are flowcharts showing the operation of the transmission control device 10 according to the operation example 1. '

When a user in a room wants to use the Internet in the room, the user connects the Internet device 32 to the ADSL modem 34 in advance by a setting method specified by the ISP. Subsequently, the user dials the extension telephone number for Internet connection using the extension telephone 31 (S00). The dialed signal is received by the transmission control device 10 via the extension control voice line 19 as a request signal for use of the Internet (a signal for requesting Internet connection), and is transmitted to the decoder 18. C is notified (Fig. 3; <1>).

Upon receiving the request signal, the decoder section 18C uses the current state of use of the Internet (here, the switching switch 17) constantly notified from the control operation section 18A to use the Internet. It determines whether or not connection to the network is possible (line availability), and notifies the voice response unit 18B of the determination result (SO1, S02).

The switching switch 17 constantly informs the control operation section 18 A of its use status. (FIG. 3; <13>), the control operation section 18A constantly notifies the use section notification from the switch 17 to the decoder section 18C (FIG. 3; <5). 〉). Accordingly, when receiving the request signal, the decoder section 18C determines whether or not a connection indicating whether the switching switch 17 has been disabled is received, thereby determining whether connection is possible. Can do o

The voice response unit 18B outputs a voice announcement voice signal indicating whether or not connection to the Internet is possible from the voice signal interface 21 to the extension control voice line 19 (FIG. 3). <3>). As a result, the voice announcement is transmitted to the extension telephone 31 that has output the request signal, and is output from the extension telephone 31. In this way, the user is notified of the connection availability.

Here, if the connection determination result indicates that the connection is possible (S02; possible), the voice response unit indicates that the connection to the Internet is possible and various settings for the use of the Internet. (For example, the user is notified of a voice signal indicating a voice announcement regarding a billing method (time charge, fixed charge (for XX yen), etc.)) (S03).

When notified of the voice announcement indicating that connection is possible, the user inputs an answer as to whether or not to make a connection, and, in accordance with the voice announcement, performs a procedure such as connection time according to a predetermined procedure. Various settings are made (S04). The input of the answer and the setting is performed by operating the extension telephone 31. When the answer and the setting are input to the extension 31, tone signals relating to these are output from the extension 31 to the extension. The tone signal is input to the decoder 18C of the controller 18 through the extension control audio line 19 (FIG. 3; <1>).

Upon receiving the tone signal, the decoder section 18C decodes and analyzes the tone signal, and determines whether various settings necessary for using the Internet have been completed (S06). ).

If the settings have not been completed (S06; incomplete), use the remaining settings. An instruction for notifying the user of a voice announcement to be made by the user is given to the voice response unit 18B (FIG. 3; <2>) ₀

In this way, the loop processing of S03 to S06 is repeatedly performed until the setting is completed. Here, when receiving the connection time set by the user, the decoding unit 18C notifies the time monitoring / charging unit 18D of the connection time (FIG. 3). <7>). However, if the connection time has not been set, the decoding unit 18C notifies the time monitoring / charging unit 18D of the preset default time as the connection time. I do.

When the setting is completed (S06; completion), the decoding unit 18C gives a request to connect the extension related to the use request to the central office to the control operation unit 18A (Fig. 3; <6 〉;). The control operation section 18A controls the switching switch 17 to connect the extension concerned to the request and the local line (SO7, FIG. 3; <14>).

When the extension and the office line are connected, the ADSL modem 34 is connected to the ADSL modem 51 and the ISP router 50 on the office side, and the linkup LED of the ADSL modem 34 is turned on. Also, a connection start signal is transmitted from the control operation unit 18A to the time monitoring / charging unit 18D, and time monitoring and charging are performed (S08, FIG. 3; <9>). Time monitoring. The charging unit 18D has a timer, and starts counting time using the timer. The state of such control operation is output to the operation panel 20 (FIG. 3; <5>,

<8>). However, whether to always output the status to the operation panel 20 can be selected.

When the connection between the extension and the office line is completed, the completion of the connection is notified from the control operation section 18A to the decoder section 18C (FIG. 3; <5>). Then, the decoder section 18C instructs the voice response section 18B to notify the completion of the connection (S09; FIG. 3; <2)).

The voice response unit 18B notifies the user of the voice announcement of connection completion (S10, Fig. 3; <3>). As described above, the Internet device 32 is connected to the Internet. This allows the user to: A desired operation can be performed on the Internet device 32 to use the Internet. Note that the voice signal is transmitted via the PBX (a) without passing through the switching switch 17, so that the extension / external call using the extension telephone can be performed as usual.

If the decoder 18B determines in step S02 that the connection to the Internet is not possible (S02: not possible), the voice responder 18B determines that the voice announcement has not been made. The user to make a setting to select whether to end the Internet 1, use procedure, or to receive a notification when the connection is possible. Notify (Sll, Fig. 3; <3>).

According to the voice announcement output from the extension telephone 31, the user sets the procedure end or the notification reception by operating the extension telephone button (S 12). By operating a button, a tone signal and / or a dial signal indicating the end of the procedure or the reception of a notification are transmitted from the extension telephone 31 to the extension via the PBX (a) and the extension control voice line 19 and the transmission control device 10 (FIG. 3; <1>).

Then, the decoder section 18C decodes and analyzes the input tone / dial signal, and determines whether it is the procedure end or the notification reception (whether or not to wait for an empty state) (S1). 3, S14). At this time, if the analysis result indicates that the procedure has been completed (S14; NO), the processing ends.

On the other hand, if the analysis result indicates that the notification has been received (S14; YES), the decoder unit 18C transmits the notification from the control operation unit 18A to the usable state. Make a call to indicate that the telephone is ready to use, and make a self-configuration, and give a notification instruction to the voice response unit 18B that the notification reception setting is completed (Fig. 3; <2>). .

The voice response unit 18B notifies the extension telephone 31 of the user of a voice announcement indicating the completion of the notification reception setting (FIG. 3; <3>). When the user is notified of the completion of the notification reception setting, the user temporarily disconnects the line of the extension telephone 31 (S16). Wait for the available status notification to arrive. One.

As described above, the user waits until the switch switch 17 is in the unusable state and cannot use the Internet immediately. A setting for notifying the user of the fact (setting to wait for notification of availability) can be made to the transmission control device 10.

The decoder section 18C is provided with a contact waiting queue, and is configured to be able to register settings of waiting for contact from a plurality of users in the contact waiting queue in the order of reception.

Also, an extension telephone number for retrying when the extension telephone line is disconnected during operation of the transmission control device 10 by the user is prepared, so that even if the operation is interrupted, the user can start from the middle. It is possible to start over.

In a setting in which the user waits for contact, as shown in Fig. 5, the decoder section 18C monitors the notification from the control operation section 18A, and the state of the switch 17 is enabled. The process of determining whether or not it is (empty) is repeated (S17, S18).

When the decoder section 18C receives the notification of the usable state from the control operation section 18A (S18; present), the decoder section 18C sets the oldest one of the settings registered in the communication waiting queue to the oldest one. Identify and make a call to the corresponding extension telephone 31 and instruct the voice response unit 18B to output a voice signal (FIG. 3; <2>).

According to the instruction from the decoder section 18C, the voice response section 18B notifies the corresponding extension telephone 31 of a voice announcement indicating that the telephone is ready for use (FIG. 3; <3>). ).

As a result, the corresponding extension telephone 31 is called (ringing), and when the user answers the call (off-hook), the user is notified of the voice announcement indicating the available state (S04). . After that, the same processing as steps S55 to S10 is performed (S21 to S23), and the user You can use the net. If the user does not respond to the call for a predetermined time, the contact waiting process ends.

Next, when the user terminates the use of the Internet, the operation as shown in the flowcharts of FIGS. 6A and 6B and the operation of the transmission control device 10 are performed. Be done.

In FIG. 6A, when terminating the use of the Internet, the user dials from the extension telephone 31 to the transmission control device 10 and requests that the connection be released. That is, when the user dials the extension telephone number for terminating the Internet using the extension telephone 31 (S201), the corresponding PB signal is decoded through the extension control voice line 19 through the decoder. The signal is input to the section 18C, and the decoder section 18C gives a voice output instruction to the voice response section 18B (S202).

The voice response section 18B outputs a voice announcement at the end of the Internet according to an instruction from the decoder section 18C, and the voice announcement is transmitted to the extension telephone 31 (S203).

When the user inputs the setting for terminating the connection (disconnecting; releasing the call) in accordance with the voice announcement to the extension phone 31, a tone signal corresponding to this setting is transmitted to the decoder section 18C (S2). 0 4).

Upon receiving the disconnection setting, the decoder section 18C gives the control operation section 18A a control instruction of the switching switch 17 and the control operation section 18C issues the switching switch in accordance with the control instruction. Controls switches 17 to release the connection between the extension and the office line.

When the connection is released, the decoder section 18C clears the time monitoring and charging section 18D by notifying the monitoring signal (indicating disconnection) of the connection processing to the time monitoring and charging section 18D. Processing is instructed (S205).

The time monitoring and charging unit 18D stops measuring the connection time between the corresponding extension and the office line, calculates a charge according to the connection time, and determines the connection time and the charge on the operation panel interface 2. 2 to the operation panel 20 (S206, FIG. 3; <8>). The output device of operation panel 20 is Time monitoring · Displays the connection time and charge received from the charging unit 18D (S207).

On the other hand, the decoder unit 1 ₈ c, compared voice response unit 1 8 B, giving a sound output instruction (S 2 0 5). In response to the voice output instruction, the voice response unit 18B outputs a voice signal indicating that the disconnection process has been completed to the user's extension telephone 31 via the voice signal interface 21 ( S208). As a result, the user can hear the end of the disconnection processing from the extension telephone 31 (S209).

The user then pays for the Internet usage charges at the front of the hotel, for example, at checkout. At this time, various forms of payment such as cash payment and card payment can be applied.

At this point, if the Internet connection time exceeds the time or fee set by the user when connecting to the Internet, an interrupt process as shown in FIG. 6B is performed.

At the time of Internet connection, the time monitoring / charging unit 18D measures the connection time. Time monitoring · If the time measured by the charging unit 18D exceeds the connection time set by the user or the connection time according to the charge set by the user, the decoder unit 18C Detects this, and gives a voice output instruction to the voice response section 18B (S301).

According to the voice output instruction, the voice response unit 18B generates a voice signal (voice guidance) indicating that the set connection time or charge has been exceeded and that the user has to inquire whether to end or continue using the service. Is notified to the user by extension call (S302).

The user determines whether to end or continue using the service according to the voice guidance output from the extension phone 31 (S303, S304). At this time, when the user terminates the use of the Internet, the processing after step S205 shown in FIG. 7A is performed, and the user is disconnected. The settlement of the processing fee is performed. On the other hand, if the use is continued, the connection conditions are reset using the extension call, and the connection between the extension and the office line is maintained.

In the above example, the user is inquired about whether to end or continue using the Internet. Alternatively, when the decoder section 18C detects that the connection time or the charge has been exceeded, the control section 18A issues an instruction to release the connection, and the control section 18A switches the switch 17 May be controlled to release the connection between the extension and the office line.

《Operation example 2》
