Abstract

PURPOSE:To eliminate the need for usual communication with a private line and for the arrangement of a clerk to a multimedia multiplexer MPX side by forming a communication line via a public telephone line with a remote control supervisor(RCS) corresponding to the occurrence of a fault, and performing control and supervision via the communication line. CONSTITUTION:When the fault occurs in an MPX 1, its interface panel (I/F) 4 reacts according to the fault, and a command is issued to line terminating equipment(LTE) 5, and complimentary and outgoing operations for a public telephone line network(PTN) 6 are performed, and the call of the RCS 3 is performed via the PTN 6. Then, a communication line between the MPX 1 and the RCS 3 is formed, and the occurrence of the fault is informed to the RCS 3. Such information is received with an I/F 8, and the capturing state of the PTN 6 is cancelled, and a state forming the communication line between the MPX 1 and the RCS 3 can be recovered. Next, capturing and outgoing operations for the PTN 6 are performed corresponding to the information at an RCS 3 side, and the call of the MPX 1 is performed, and the control and the supervision for the MPX 1 are performed via the communication line of the PTN 6. In such a way, the control and the supervision from a remote place can be performed without necessitating the private line usually.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an in-house network that uses multiple communication formats.
This invention relates to a system for controlling and monitoring a multimedia multiplexing device to be constructed from a remote location.

[Conventional technology]

When building an in-house network that uses multiple communication formats, each business site is connected via a private line or a line borrowed from a telecommunications carrier, and a multimedia multiplexer (hereinafter referred to as MPX) is used to connect the The control and monitoring of this MPX is performed by a remote control monitoring device (hereinafter referred to as RCS) installed at a specific workplace.

For this reason, there is a method in which the MPX and RC8 are always in contact with each other via a dedicated line, and control and monitoring is performed via this, or there is no constant contact between the MPX and the RCS. ■When a problem occurs on the side, the person in charge of the relevant department
A telephone contact is made to the CS side, and in response, a communication path is formed from the RCS side via a public telephone line, and the M
A method of controlling and supervising the PX is used.

[Problem to be solved by the invention]

However, the method of always contacting via a dedicated line has the drawback that the usage fee for the dedicated line is expensive, while the method of contacting by telephone in response to a failure
This requires the placement of a staff member on the X side, creating a drawback that hinders labor saving.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention is constituted by the following means.

In other words, in the above-mentioned remote control monitoring system, when a failure occurs in the MPX, the MPX automatically notifies the RCS via the public telephone line, and responds accordingly.
The CS forms a communication path via a public telephone line, and controls and monitors the MPX via this communication path.

[Effect]

Therefore, if a failure occurs in the MpX, this will be automatically reported to the RCS via the public telephone line, and in response, the RCS will form a communication path via the public telephone line, and control and It will be monitored.

[Example] Hereinafter, the present invention will be explained in detail with reference to a block diagram showing an example.

In the figure, MPX1 is building an in-company network via a leased or self-employed line 2, and RCS3 is installed at a remote location, and there is no contact between the two at all times. .

On the other hand, when a failure occurs in MPXI, its interface board (hereinafter referred to as I/F) 4 responds and connects the line terminal equipment (hereinafter referred to as LTE) 5, which consists of a modem and a communication network control device, etc. The public telephone network (hereinafter referred to as
PTN) 6 to perform acquisition and transmission operations,
Make a call to RCS3 via TN6.

Then, LTE7 on the RCS3 side performs a response operation, and M
In order to formalize the communication path between PX1 and RC83, MPX1's! /F4 notifies RCS3 of the occurrence of a failure using a code.

This notification is received by I/F8 of RCS3 via LTE7, and in response! /F8 sends a response signal, so this is sent to MPXI's! /LTK when F4 receives
5 to terminate the notification and release the capture state of the PTN 6. As a result, the communication path formation state between the MPX 1 and the RCS 3 is restored.

Next, on the RCSa side! /According to the report received by F8, x7vB gives a command to LTET, and PTN6
The MPX 1 performs acquisition and transmission operations, and calls the MPX1.

When LTE5 performs a response operation in response, PTN6
Since a communication path is formed between the two via the PTN 6 communication path, the RCSS side maintains this state from now on and controls and monitors the MPX 1 via the communication path of the PTN 6.

In addition, in order to maintain security, it is desirable to use a personal identification number such as a password in response to an incoming call using LTE5 and LTE7, and to enter a complete response state after receiving this code.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, when a failure occurs in the multimedia multiplexing device, only a notification is automatically sent to the remote control supervisory device via the public telephone line, and Accordingly, the remote control and monitoring equipment has established a communication path via the public telephone line, and has been controlled and supervised through this, eliminating the need for constant communication between the two equipment through a dedicated line. This eliminates the need for personnel to be assigned to the multimedia multiplexing device, resulting in labor savings and improved economic efficiency, and significant effects can be obtained in remote control and monitoring of the multimedia multiplexing device.
