Abstract

PURPOSE:To improve the economical performance and the flexibility for addition and change of new test function, by centralizing and installing a channel test device and a channel test controller at a centralized maintenance station. CONSTITUTION:The information needed to set a test channel selected by a time division channel 61 of a station 60 to be centralized and among the information fed to a maintainer interface device 51 by a maintainer and needed for test is transferred to a call process controller 62. At the same time, the information needed to set a channel test device 52 at a test state and the information needed to connect a designated station, i.e., a station 60 to the device 52 among stations 60... after the actuation of a switch 53 are transmitted to each corresponding device from a channel test controller 54. The device 52 is connected to the channel 61 via the switch 53 and a digital transmission line D and forms a selected test channel to perform various types of tests.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a maintenance-intensive system that allows communication path testing around a plurality of digital switching tanks accommodating subscribers to be carried out economically and with flexibility.

FIG. 1 is a relay system diagram of a conventional maintenance centralized system, in which 10 is a maintenance centralized station 20. . . , n are digital switching stations each accommodating a subscriber or a trunk line (not shown), in this case a centralized station, which is connected to the maintenance centralized station 10 via, for example, a digital transmission line. The maintenance central station 10 has a maintenance person interface device 11 having a display device such as a lamp drawing (not shown) and an input device such as a power key date, and centralizes the information necessary for the test inputted from the maintenance person interface device 11. Station 20. . . , to a designated concentrated station among the concentrated stations 20,
. . . a distribution selection device 12 that selectively connects the test result information returned from n to the maintenance person interface device 11;
and a transmitting/receiving device 13.14 for inter-office transfer of information between the maintenance central station 1o and the concentrated stations 20°, . . . , n.

Also, the concentrated station 20. . . . , each of n is the time division communication path 2

In the conventional maintenance intensive method configured as described above,
The communication path is tested as follows. When the information necessary for the maintenance test is input to the maintenance operator interface device 1 at the maintenance central station, the information selected for testing the time-sharing communication path 2 from among the input information is inputted to the maintenance operator interface device 1. The information necessary to set up the test communication path is distributed to the concentrated station designated by the distribution selection device 12-1, here, the concentrated station 20, and transferred to the transmitting/receiving device 13 digital transmission path D1.

The information necessary to set the distribution selection device 12-
2 to the concentrated station 20 specified by the transmitting/receiving device 1.
4. The signal is transmitted to the channel test control device 24 of the concentrated station 20 via the digital transmission path D2 and the transmitting/receiving device 26. As described above, when the information necessary for the test inputted by the maintenance person is given to the concentrated station 20, the control devices 23 and 24 control the selected time division communication path 2, respectively, based on the given information. The test communication path is completed and the communication path test device 22 is controlled. Through the above control, the call path test control device 24 monitors the test status of the test call path selected in the time-division call path 21 via the call path test device 22, and upon completion, sends a signal to that effect to the call processing control device 23. The test results obtained through monitoring are collected and transmitted to the transmitting/receiving device 26 and the digital transmission line D2.
, the transmitting/receiving device 14, and the distribution selection device 12-2, the test result is transmitted to the maintenance person interface 11, and the test result is displayed on the display device of the maintenance person interface 11.

It has a built-in switch, and distributing it to each concentrated station would be uneconomical for the maintenance centralized system as a whole.
In addition, since the test system is prone to change due to changes in the functions of the main body of the exchange, the call path test equipment 2
2 and the communication path test control device 24 have problems such as extremely poor flexibility with respect to the addition and modification of new test functions.The present invention has been made in view of these points. And,
