Abstract

PURPOSE:To lower cost required for remote maintenance by eliminating necessity to provide a special line for the remote maintenance by making the contents of maintenance information and a sub address correspond to each other, and transmitting the maintenance information by the line for data communication. CONSTITUTION:In terminal equipment 1, the maintenance information 5 is generated by a maintenance information generation circuit 4 at every definite time, and it is, put on code information 7 by converting it into code information by a maintenance information-code conversion circuit 6, and a call origination circuit 10 originates a call after adding the code information to address information 9 from an address storage circuit 8 as the sub address. In the terminal equipment 2 of an opposite party, when the call from the terminal equipment 1 terminates through an ISDN 3 and a D channel, it recognizes the maintenance information of the terminal equipment 1 by discriminating the sub address of the incoming information.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a remote maintenance system, and in particular to an integrated service digital network (hereinafter referred to as ISD).
N) relates to a remote maintenance method for a terminal device connected to the 2B+D method or the 23B+D method.

0002

2. Description of the Related Art Conventionally, this type of remote maintenance system has been a system in which a line for remote maintenance is provided separately in addition to a line for data communication.

0003

SUMMARY OF THE INVENTION The above-described conventional remote maintenance system has the drawback of high costs because it requires a separate line for remote maintenance in addition to the line for data communication.

0004

[Means for Solving the Problem] The remote maintenance method of the present invention is applicable to the 2B+D method or 23B method of the ISDN network.
A generation means for a terminal device connectable to the +D system to generate its own maintenance information, and a conversion means for converting the maintenance information from the generation means into a specific code determined in advance between the partner terminal device and the other terminal device to which the maintenance information is transmitted. a storage means for storing the address of the partner terminal device; and a code indicating the maintenance information converted by the conversion means is added as a subaddress to the address of the partner terminal device stored by the storage means at regular intervals. and calling means for making a call to the other party's terminal device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. The terminal device 1 and the partner terminal device 2 are terminal devices that can be connected to the ISDN 3. The maintenance information generation circuit 4 generates maintenance information 5 for the terminal device 1 itself. Maintenance information-code conversion circuit 6 is maintenance information 5
is converted into code information 7 corresponding to the content of predetermined maintenance information. Address storage circuit 8 stores address information 9 of partner terminal device 2 . The calling circuit 10 adds the code information 7 as a subaddress to the address information 9 and makes a call to the destination terminal device 2 at regular intervals.

Next, the operation of this embodiment will be explained. In the terminal device 1, the maintenance information generation circuit 4 generates maintenance information 5 at regular intervals, and the maintenance information-code conversion circuit 6 converts this into code information and puts it on the code information 7, and the calling circuit 10 generates the address. Code information 7 is added as a subaddress to address information 9 from storage circuit 8, and a call is made. When a call from the terminal device 1 arrives through the D channel via the ISDN 3, the destination terminal device 2 can recognize the maintenance information of the terminal device 1 by identifying the subaddress in the incoming call information.

[0008]

[Effects of the Invention] As explained above, the present invention associates the contents of maintenance information with sub-addresses and transmits maintenance information over a data communication line, so a separate line for remote maintenance is provided. This eliminates the need for remote maintenance, which has the effect of reducing the cost required for remote maintenance.

Claims (1)

[Claims] 1. Generation means for a terminal device connectable to a basic access (hereinafter referred to as 2B+D) method or a primary access (hereinafter referred to as 23B+D) method of an integrated service digital network to generate maintenance information for the terminal device itself; a conversion means for converting the maintenance information from the generation means into a specific code determined in advance with the partner terminal device to which the maintenance information is transmitted; a storage means for storing the address of the partner terminal device; The present invention is characterized by comprising a calling means that adds a code indicating the maintenance information converted by the converting means to the stored address of the destination terminal device as a subaddress and makes a call to the destination terminal device.
