KR960027661A - Automatic test method for ISDN subscriber circuit - Google Patents

Abstract

The present invention relates to a test method for subscriber circuits among subscriber matching functions between a TDX-1B electronic switch and an integrated information communication network (hereinafter referred to as ISDN). A first step of judging whether a problem such as reception has occurred, a second step of separating the subscriber circuit from the line matching means if it is determined that the test of the subscriber circuit is necessary in the first step, and Providing an automatic test method for an ISDN subscriber circuit comprising a third process of connecting a separate subscriber circuit with an inspection means and a fourth process of inspecting the subscriber circuit connected in the third process for each subscriber matching function. The exchange can automatically notify the operator of the fault condition of the subscriber line without reporting the fault of the subscriber. In the same basic communication system, the service quality can be improved and the maintenance function of the exchange can be enhanced in terms of communication continuity.

Claims (5)

A test method for subscriber circuits among subscriber matching functions between a TDX-1B electronic switch and an integrated telecommunication network, comprising: a first judgment for determining whether a problem such as self-detection or an operator's test necessity or a problem report is received; Process; A second step of separating the subscriber circuit from the line matching means when it is determined that the test of the subscriber circuit is necessary in the first step; A third step of connecting the subscriber circuit separated in the second step with an inspection means; And a fourth process of inspecting the subscriber circuit connected in the third process for each subscriber matching function. 2. The automatic test method for an ISDN subscriber circuit according to claim 1, wherein the fourth process comprises a check process of a basic access subscriber circuit, a check process of a primary access subscriber circuit, and a primary group access check process. An active test method for basic access subscriber circuits of subscriber circuits among subscriber matching functions between a TDX-1B electronic switch and an integrated telecommunication network. Generating a unique number; A second step of separating the corresponding subscriber circuit generated in the first step from the subscriber line; A third step of requesting a test after connecting the subscriber line separated in the second step to an inspection means; And a fourth step of deciding whether an active state is recognized within a predetermined time by starting activation in the inspection means and deeming it to be normal when recognized. A B1 channel loopback test method of a basic access subscriber circuit to a subscriber circuit among subscriber matching functions between a TDX-1B electronic switch and an integrated telecommunication network, wherein the B1 channel of the corresponding subscriber subscriber line loops back to the network side upon request of a test. Step 1; A second step of transmitting simulated random data or a predetermined pattern through a specific channel of DLC (2.048 Mbps) when the loopback to the network side is formed in the first step; A third step of comparing the transmitted / receive data and determining whether it is normal when the data transmitted in the second step is looped back through the two-wire route through the switching circuit; And the fourth step of notifying the operator of the corresponding subscriber circuit number if it is determined that there is an error by comparing the transmission / reception data of the B1 channel in the third step. Way. In B1 channel loopback test method of basic access subscriber circuit of subscriber circuit among subscriber matching function between TDX-1B electronic switch and Telecommunication network, trunk line with transmission and reception separated can monitor line status even during service. A first step of transmitting a loopback command to the PMUX using the conserved channel without leaving the process; And a second step of extending the loopback point to the basic access subscriber circuit in the PMUX. ※ Note: The disclosure is based on the initial application.
