Abstract

PURPOSE:To decrease the number of subscriber line test devices, by incorporating various subscriber line test devices in a telephone exchange. CONSTITUTION:In dialing a telephone number of subscriber test at the subscriber line test from a subscriber telephone set 1, a relay contact 2 is closed, numeric information from the subscriber telephone set 1 is received at a subscriber line test master device 7 via a subscriber test slave device 9, the test is executed via the test slave device 9 and the result is transferred to the telephone set 1. The relay contact 2 is closed with a program of a central controller 10 at the test of automatic subscriber line, the test is performed by the control of program, the result is transferred to the central controller 10. At the test from a subscriber test board 8, the subscriber line test slave device 9 performs the test with the designation of the test items and the result is transferred to the test board 8.

Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to a subscriber line testing method for Shimabashi Kaiso.

In particular, the subscriber line test 1 inspection method in a time-division 'Nariko exchange' has traditionally been used for equipment used for subscriber line tests operated by subscriber telephones, and for automatic subscriber line tests carried out by the exchange under software program control. A device for exchanging information with a subscriber line test stand and a device for performing subscriber line tests by exchanging information with a subscriber line test stand were housed separately in the IJ link. Therefore, especially in small-capacity exchanges or in exchanges (master stations) that have multiple remote stations (>1 slave stations) that consist only of concentrator switches, each test device must be installed in each of the master and slave stations. First, it had the disadvantage of increasing the number of facilities.

The present invention integrates a subscriber line testing device with similar functions and an automatic subscriber line testing device into a subscriber line testing device from a subscriber line testing stand, and controls the subscriber line testing device that the conventional subscriber line testing device had. The procedure solves the above-mentioned drawbacks of controlling the system by an interface device with a subscriber line test stand accommodated in the network, and provides a subscriber line testing method that reduces the number of subscriber line test equipment. be.

According to the present invention, a device housed in a test link and used for a subscriber line test operated by a subscriber telephone, and a device used for an automatic subscriber line test carried out under software control can be operated from a subscriber line test stand. A communication path is connected between the control device and the test device, which is integrated with the test device that performs the subscriber line test under the control of the control device, and has an interface function with the subscriber line test stand accommodated in the network and a test procedure control function. Thus, a subscriber line testing method for a telephone exchange is obtained, which is characterized in that the test is carried out under the control of the control device.

Next, examples of the present invention will be described.

FIG. 1 is a relay system diagram showing an embodiment of the present invention.

5 is a line concentration switch, and 6 is a time division switch.

7 is a subscriber line master device as a control device having an interface function with a subscriber line test stand 8 accommodated in the network and a test procedure control function, 8 is a subscriber line test stand, and 9 is a test link. equipment housed in the system and used for subscriber line tests operated by subscriber telephones, equipment used for automatic subscriber line tests conducted under software control, and equipment used for subscriber line tests controlled by subscriber line test stands. The subscriber line equipment incorporating the implementing equipment, 10, is the central control unit →.

When testing the subscriber line from the subscriber telephone, when the telephone number for the subscriber line test is turned, the relay contact 2 is activated, and the subscriber telephone 1 is connected to the subscriber line test subdevice 9 from the subscriber telephone iso 1. The sent test item designation numerical information is sent to the subscriber test device 9t-
The subscriber line test device 7 receives the test data via the subscriber line test device 7, controls the subscriber line test slave device 9 according to the numerical information, executes the test, and sends the result to the subscriber line slave device.

During the automatic subscriber line test, the relay contact 2 is operated under the control of the program stored in the central controller 1o, and a call path is connected between the subscriber line test child bag 9 and the subscriber line test parent device 7. Ru. The test is started under the control of the program, and the test procedure is controlled by the new subscriber line #, 7, and the results are sent from the subscriber line test child device 9 to the central control device 10 via the subscriber line master device 7. be transferred.

When testing from the subscriber line test stand 8, the communication path between the subscriber line test master device 7 and the subscriber line test child device 9 is connected,
The subscriber line test child device 9 conducts a test based on the designation of test items from the subscriber line test stand 8, and transfers the results to the subscriber line test stand 8 via the subscriber line test master device 117.

As explained above, the present invention integrates various types of subscriber line testing equipment to produce small-capacity switching equipment,
