ADSL (Asymmetrical Digital Subscriber Loop) subscriber terminal equipment testing and maintaining system

Abstract

The invention relates to an ADSL (Asymmetrical Digital Subscriber Loop) subscriber terminal equipment testing and maintaining system. The system comprises a central controller, a digital subscriber line access multiplexer frame, a line simulation attenuator, a subscriber terminal to be tested and maintained and a computer testing platform, wherein the central controller is connected with one end of the digital subscriber line access multiplexer frame, and the other end of the digital subscriber line access multiplexer frame is connected with the line simulation attenuator; the line simulationattenuator is connected with the subscriber terminal to be tested and maintained through an interface, and the subscriber terminal to be tested and maintained is connected with the computer testing platform through another interface. Compared with the prior art, the system is applicable to the maintenance of products of various manufacturers, can respond in time, does not influence the public network and is low in price.

Description

technical field [0001] The invention relates to a terminal equipment testing and maintenance system, in particular to an ADSL user terminal equipment testing and maintenance system. Background technique [0002] ADSL (Asymmetric Digital Subscriber Line) asymmetric digital subscriber line loop is the main business currently carried out by China Telecom, and it is also a mainstream way to realize broadband Internet access. On the user side, the ADSL user terminal is used to decode the line transmission signal, and then Transform it into an Ethernet transmission format, and connect with the computer we use through the TCP / IP protocol to realize broadband Internet access. [0003] There are several problems existing in the normal operation of the existing ADSL user terminal equipment: [0004] (1) The number of user terminals is large, reaching several million, requiring a large amount of maintenance; [0005] (2) The user terminal is used in the user's home, and the use envir...

AI Technical Summary

Problems solved by technology

[0004] (1) The number of user terminals is large, reaching several million, requiring a large amount of maintenance;

[0005] (2) The user terminal is used in the user's home, the use environment varies greatly, is greatly affected by people and the outside world, and is easily damaged, and the number of damage will increase sharply when there is a sudden climate change;

[0006] (3) There are many types of user terminal equipment, and there are many manufacturers, so it is impossible to correspond one by one;

[0007] (4) Since the user terminal equipment manufacturer is facing customers all over the country, the maintenance time is very long and the delivery cannot be delivered in time;

[0008] (5) The repairing party undertakes the repair work for the products in the early stage and out of the warranty period;

[0009] (6) In response to the lack of user terminal equipment, telecommunications companies continue to increase spare parts, resulting in rising costs for maintaining operations
