Abstract

PURPOSE:To immediately conduct a system/subscriber test from a maintenance center by connecting a call line required for the system/subscriber line test to a general telephone network and connecting a trunk for call test and a sound source for test on an exchange-side to a fault device. CONSTITUTION:When the fault occurs in an output trunk 13, for example, it is detected in an operation device band subscriber circuits 4 and 5 are called. When a connection device 3 detects the incoming call, it transmits an incoming call message and incoming ringing to a telephone system for call test 2. A maintenance man inputs a response command to a maintenance operation terminal 1. Thus, the terminal 1, and the system 2 are connected to the maintenance operation device 26 and a channel switch 19. When the maintenance man supplies the test command for conducting the test of the output trunk 13 and connects the output trunk 13 to an input trunk for test 15, they are connected to a call test trunk 25. Thus, the maintenance man can recognize the presence or absence of tone from a tone source, a level and the like in the system for call test 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance and operation center connection system for connecting a plurality of exchanges to be tested and a maintenance and operation center for intensively testing these exchanges via a general telephone network.

[0002]

2. Description of the Related Art Conventionally, in a system in which an exchange to be tested and a maintenance operation center for testing this exchange are connected, transmission and reception of control information, status information, system and subscriber line test information between them. With regard to the above, first, the fault information is notified from the faulty exchange side to the maintenance and operation center side through the data line using the general telephone network. Thus, when it is necessary to conduct a call test using voice, the maintenance operation center side connects the data line for transmitting / receiving the test information and the call line for the call test again to the exchange side.

[0003]

As described above, in the conventional maintenance operation center connection system, when a failure occurs in the exchange, the exchange notifies the maintenance operation center of the failure information, and the maintenance operation center sends the failure information. After checking, if it is determined that it is necessary to conduct a call test using voice, the maintenance operation center must connect the data line for sending and receiving test information and the call line for call test again. There is a drawback that the system and subscriber test cannot be started immediately and it takes time.

[0004]

According to the maintenance operation center connection system of the present invention, a plurality of exchanges to be tested and a maintenance operation center for intensively performing tests of these exchanges are connected via a general telephone network. In the maintenance operation center connection method, the connection device on the exchange side holds a fault occurring in the exchange and makes a call via a data line and a telephone line,
The connection device on the side of the maintenance operation center detects this incoming call, connects the call via the data line to the maintenance terminal and displays the transferred fault data, and displays the call via the call line on the telephone device. After connecting and calling this telephone device, the connection device of the exchange is connected to the trunk for call test provided on the exchange side in response to the response from the maintenance and operation center side, and subsequently the test instruction of the operation input causes the exchange device to connect to the exchange. The control device is configured to connect the trunk and the test sound source via the device in question.

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

FIG. 1 is a diagram showing a system configuration for explaining an embodiment of the present invention. In FIG. 1, the maintenance operation center includes a maintenance operation terminal 1 and a telephone device 2 for call testing.
And the connection device 3, and the communication path switch 6 of the exchange on the maintenance operation center side via the subscriber circuits 4 and 5.
Is tangent to. The communication path switch 6 includes trunks 7, 8,
It is connected to the speech path switch 12 of the exchange under test via the general telephone network 9 and the trunks 10 and 11. A communication path switch 19 for switching a communication line for maintenance and operation and a maintenance operation device 26 for control for maintenance and operation
Is connected to the speech path switch 12 via the connection device 18 and the subscriber circuits 16 and 17, and the speech path switch 19 is connected to the speech path switch 12 via the trunks 21, 22, 23 and 24. The tone sound source 20 for the call test is connected to the call path switch 19. One of the outgoing trunks 13 which has become an obstacle is a test return relay 14
The test trunk 15 and the other end are connected to the communication path switch 12 via the.

A case where a failure occurs in the outgoing trunk 13 will be described below as an example. The failure of the outgoing trunk 13 is detected by the maintenance operation device 26, and the failure information is accumulated in the connection device 18. After the failure information is stored, the connection device 18 uses the subscriber circuits 16 and 17 to make a call to the subscriber circuits 4 and 5 via the data line and the communication line, respectively.

The connection device 3 detects an incoming call to the subscriber circuits 4 and 5, and sends an incoming message and an incoming ringing to the maintenance and operation terminal 1 and the telephone device 2 for call testing, respectively.
After confirming these incoming messages and incoming ringing, the maintenance person at the maintenance operation center inputs a response command at the maintenance operation terminal 1.

With this command, the connection device 3 responds to the above-mentioned incoming call, whereby the maintenance operation terminal 1 and the telephone device 2 for call test are connected device 3, subscriber circuits 4, 5
Trunk 7, 8 Call path switch 6, General telephone network 9, Trunk 10, 11, Subscriber circuit 16, 17, Connection device 1
8. The maintenance operation device 26 and the communication path switch 19 are connected via the communication test trunk 25.

After the completion of this connection, the maintenance person inputs a test command for testing the outgoing trunk 13 from the maintenance / operation terminal 1 to connect the outgoing trunk 13 to the incoming test trunk 15 via the test return relay 14. At the same time, the outgoing trunk 13 and the test incoming trunk 15 are called via the tone path 20 and the call path switch 12, and the trunks 23 and 24 via the call path switch 12, the trunks 21 and 22 and the call path switch 19 of the exchange under test, respectively. Connect to test trunk 25. By this connection, the maintenance staff of the maintenance operation center can confirm the presence or absence of the sound from the tone sound source, the level, etc. on the telephone device 2 for the call test.

[0011]

As described above, according to the present invention, when connecting the exchange to be tested and the maintenance and operation center, the fault information generated in the exchange is held, and this fault information is stored in the data line of the general telephone network. Use it to report to the maintenance operation center, connect the telephone line required for system and subscriber line testing to the maintenance operation center using the general telephone network, and use the trunk for the call test and the test provided on the exchange side. Since it is configured to connect with the sound source of the device via the corresponding device that has failed, the effect that the system and subscriber test can be immediately started from the maintenance operation center by using the set failure report line and communication path Have.
