Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a remote maintenance system for a communication device.

[0002]

2. Description of the Related Art In recent years, key telephone apparatuses have made remarkable progress. And the needs of the user of the key telephone device have been diversified. To meet that need,
Manufacturers are competing to achieve higher functionality by setting data.

[0003] By the way, in such a high-function button telephone device having a large number of data settings, it is very difficult for a user without specialized knowledge to change the data settings. Therefore, when the user changes the data of the key telephone apparatus, the actual situation is that the user has only to request a technician of a specialty store having specialized knowledge.

[0004] However, it is very inefficient for a technician at a construction shop to go to each user for some data change. Therefore, remote maintenance was devised. This allows the data setting of the key telephone device to be changed by remote control using a telephone line, even if a technician of a specialty store does not go out.

[0005] In a conventional remote maintenance system, the following processing is performed.

First, a call is made from a remote maintenance center to a key telephone device for which remote maintenance is to be performed. As a result, the key telephone device that receives the call rings the ring tone. The user of the key telephone apparatus responds to the incoming call and recognizes that the remote maintenance is the intended incoming call. At the same time, the user of the key telephone device operates according to the guidance of the remote maintenance center so that the key telephone device enters the remote maintenance mode.

[0007]

However, the above-mentioned prior art has the following drawbacks.

First, the user of the key telephone apparatus which receives the remote maintenance does not know whether or not the call is from the remote maintenance center when the call is received.
You have to respond. Also, when you respond,
Operations must be performed according to the guidance of the remote maintenance center.

Secondly, the remote maintenance communication deviates from the original use purpose for the user of the key telephone apparatus because the communication line is monopolized for a purpose other than the telephone, and the communication is preferably performed if possible. If the traffic is performed during low business hours or when the user is absent, the intended use of the key telephone device can be avoided.

However, the conventional system for performing remote maintenance cannot perform remote maintenance when the key telephone device user is absent or cannot answer the telephone.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a remote maintenance system for a communication device that can perform remote maintenance without bothering a user.

[0012]

Means for Solving the Problems The invention according to the present application comprises a means for capturing an office line, a means for recognizing a dial number of a caller, a means for storing a dial number of a remote maintenance center, and a remote maintenance signal. And a switching unit for connecting the transmitting and receiving unit of the remote maintenance signal with the transmitting / receiving unit of the remote maintenance center. When receiving an incoming call, the dial number of the caller is recognized, and the dial number of the caller is stored in the remote maintenance center. When a dialed number is matched, the line is captured without ringing,
The remote maintenance is automatically performed by connecting the remote maintenance center and a remote maintenance signal transmission / reception unit.

FIG. 2 is a flowchart showing a remote maintenance operation in the present embodiment. Hereinafter, a procedure for performing remote maintenance from an outside line will be described with reference to FIG.

Conventionally, a service called caller ID notification has been provided only in the ISDN network. However, a caller ID notification service using a modem is being put to practical use in the PSTN network. Therefore, in this embodiment, an operation for performing remote maintenance in the case of the PSTN network will be described.

First, an incoming call is entered from the remote maintenance center to the key telephone device using the outside line network 111 (S101).

The key telephone apparatus which receives the incoming call detects this in the external line interface 101,
The central processing unit 107 instructs the time switch 102 to connect to the modem unit 105. Modem unit 105
Sends the caller ID data sent from the outside line network 111 to the central processing unit 107 (S102).

The central processing unit 107 receiving the data
Confirms whether it matches the telephone number of the remote maintenance center registered in the RAM 108 in advance (S103).

If the telephone number does not match the telephone number of the remote maintenance center, the central processing unit 107
Unlike the incoming call for the purpose of the remote maintenance from the remote maintenance center, it is determined that the incoming call is a normal incoming call.

The central processing unit 107 transmits to the telephone 110 via the DLIC 109 for controlling the transmission of the telephone that the external line network 111 has called. The telephone 110 receives the data of the content of the incoming call, and activates the speaker amplifier to make a ring tone sound.

After confirming that the speaker amplifier of the telephone 110 has been activated, the central processing unit 107 operates the time switch 102 to connect the sound source 106 storing the ring tone to the DLIC 109 (S110). As a result, a ring tone sounds, and the process proceeds during communication (S111).

Also, in S103, if the data of the caller telephone number sent from the outside line network 111 matches the telephone number of the remote maintenance center, the central processing unit 107 does not send a ring tone to the telephone 110. . Then, the central processing unit 107 instructs the time switch 102 to connect the receiving line of the external line interface 101 to the remote maintenance signal receiving unit 103. In addition, an instruction is given to connect the transmission unit of the external line interface 101 to the remote maintenance signal transmission unit 104 (S104).

Thus, remote maintenance is started between the remote maintenance center and the key telephone device (S105). At this time, the central processing unit 107
An external line lamp corresponding to an external line used for remote maintenance is turned on the telephone 110 via the LIC 109, and it is made clear to the user of the key telephone apparatus that the external line is being used.

Thereafter, when the remote maintenance is completed (S106), the line is automatically released (S106).
107). At this time, the central processing unit 107 outputs the DLIC10
The external line lamp corresponding to the external line that has been lit via 9 is turned off. Thus, the operation of the remote maintenance is completed.

[0026]

As described above, the remote maintenance system in the communication device of the present invention recognizes the dial number of the caller and generates a ring tone when the dial number matches the dial number of the remote maintenance center stored in advance. By capturing the office line without ringing and switching connection between the remote maintenance center and the remote maintenance signal transmitter / receiver, the user of the communication device needs to respond to the incoming call for performing the remote maintenance. Not
Also, there is no need to perform complicated operations. Furthermore, there is an effect that remote maintenance can be performed even when the user of the communication device is absent or when a call cannot be made.
