Abstract

PURPOSE:To cope with a fault by a remote control even when a maintenance person doesn't directly go to a site, to speedily cope with the fault at the time of the occurrence of the fault at a user side, and to reduce a cost than the remote maintenance system to be always monitored. CONSTITUTION:An incoming sub-address judging part 2 divides incoming sub- address information elements received from a network side, compares the received data with the unique sub-address data of a number storage part 1, and communicates the result to a state monitoring part 4. A maintaining state closure testing part 3 turns the device into a maintaining state by the output of the state monitoring part 4, operates a diagnostic test, outputs the tested result to a tested result communicating part 5, releases the maintaining state, and returns the device to an activating state enabling a normal communication. The tested result communicating part 5 communicates the result of the diagnostic test operated by the maintaining state closure testing part 3 through a B channel or D channel.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite ISDN device having a telephone function and a data communication function compatible with an ISDN network, and more particularly to a composite ISDN device with a spot maintenance function having a function of setting a maintenance state by remote control. .

[0002]

2. Description of the Related Art In a conventional composite ISDN device, when performing remote maintenance, functions that are not incorporated in a remote maintenance management system have been disabled from the time the device was started up.

[0003]

SUMMARY OF THE INVENTION This conventional composite IS
In the DN device, the remote maintenance system could not investigate the cause of the failure that occurred in the device that was not built into the remote maintenance system from the beginning and could not recover from the failure. Also, when repairing a fault, maintenance personnel can directly use the composite type I
There has been a problem that it is necessary to go to the site where the SDN device is installed.

[0004]

[Means for Solving the Problems] Composite ISDN of the present invention
The device is a composite ISDN device that has both a telephone function and a data communication function that can be connected to an ISDN network, and a maintenance status blockage test unit that creates a loopback test or a hardware test status of this device and outputs a diagnostic test result. A number storage section storing a preset unique sub-address and sub-address data in an incoming message received from the ISDN network are separated and compared with the sub-address number stored in the number storage section for judgment. The maintenance status blocking test section is driven by the incoming sub-address determination section and the output from the incoming sub address determination section to maintain the maintenance status, or the maintenance status blocking test section is stopped to release the maintenance status and return to the normal service status. The state monitoring unit that returns or returns, and the state monitoring unit that receives the diagnosis result of the maintenance state blocking test unit A test result notifying unit for notifying a maintenance center of a diagnostic test result via a B channel or a D channel according to an instruction, and when the preset unique sub-address number is called from the remote maintenance center. It is characterized by being in a maintenance state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the composite ISDN device of the present invention.

A unique sub-address number is preset in the number storage unit 1 and is connected to the incoming sub-address determination unit 2. The incoming sub-address determination unit 2 is connected to the number storage unit 1 and the status monitoring unit 4, separates the incoming sub-address information element in the incoming message received from the network side when receiving an incoming call, and stores it in the received data and the number storage unit 1. The status monitoring unit 4 is notified of the result of comparison and judgment with the unique sub-address data that has been stored. The maintenance status blockage testing unit 3 is connected to the status monitoring unit 4 and the test result notifying unit 5, and the composite IS
The DN device is put into the maintenance state and a diagnostic test is performed to output the test result to the test result notifying unit 5, or the maintenance state is released to return to the normal communication-enabled operating state. State monitoring unit 4
Is connected to the incoming sub-address judging unit 2, the maintenance status blocking test unit 3 and the test result notifying unit 5, and judges the status of the present composite ISDN device by the input from the incoming sub address judging unit 2 and closes the result to the maintenance status blocking. It outputs to the test unit 3 and also outputs to the test result notification unit 5 so as to transmit the diagnostic test result. The test result notifying unit 5 is connected to the maintenance status blocking test unit 3, the status monitoring unit 4, and the network, and outputs the diagnostic test result performed by the maintenance status blocking test unit 3 to the B channel or D channel.
Notify via channel.

Next, the operation of this embodiment will be described. If the user is performing normal communication and a failure occurs for some reason, the maintenance center is informed of the failure. At the maintenance center that receives the call, a unique sub-address number that is set in advance is added to the subscriber number of the user who has been contacted in order to activate the spot maintenance function for the device in which the failure has occurred, and the incoming call is made. Upon receipt of the incoming call, the composite ISDN device checks the sub-address, and if it matches the registered unique number, it activates the maintenance status blocking test unit 3 to enter the maintenance status and disconnects the incoming call from the maintenance center. For an incoming call from a third party in this state, the state monitoring unit 4 rejects the incoming call and creates a temporary blocked state. Then, the maintenance status blockage test unit 3 performs self-diagnosis of the present composite ISDN device and sends the result to the test result notification unit 5. Then, when an incoming call arrives from the maintenance center to a preset unique sub-address, the state monitoring unit 4 activates the test result notifying unit 5 to notify the maintenance center of the result, and further releases the maintenance state. The instruction is sent to the maintenance status blocking test unit 3. By releasing the maintenance state, it becomes possible to respond to a normal incoming call and communicate.

[0008]

As described above, according to the present invention, even if the present invention is not incorporated in the remote maintenance system from the beginning, by incorporating it in the maintenance system when a failure occurs, remote maintenance of the device becomes possible, and maintenance personnel can Disability can be handled remotely without having to go directly to the site. In addition, even if it is not built into the remote maintenance system for constant monitoring, where users pay regular maintenance costs, it is possible to quickly respond to failures when a failure occurs, and the cost can be reduced compared to the remote maintenance system for constant monitoring. Have.
