Test and maintenance system for ADSL (Asymmetrical Digital Subscriber Loop) user access device in home network

Abstract

The invention relates to a test and maintenance system for an ADSL (Asymmetrical Digital Subscriber Loop) user access device in a home network. The test and maintenance system comprises a master test terminal, an auxiliary test device, a local side separator, a digital subscriber line access multiplexer, a public network and a to-be-tested user access device, wherein the public network is connected with the digital subscriber line access multiplexer, the digital subscriber line access multiplexer is connected with the to-be-tested user access device by the local side separator; and the master test terminal, the auxiliary test device and the to-be-tested user access device are sequentially connected. Compared with the prior art, the system provided by the invention has the advantages of having a fast response speed of user maintenance and reducing the number of spare parts.

Description

technical field [0001] The invention relates to a test and maintenance system for network terminal equipment, in particular to a test and maintenance system for ADSL user access equipment in a home network. Background technique [0002] ADSL technology is a new high-speed broadband technology that runs on the original ordinary telephone line. It uses an existing pair of telephone copper lines to provide users with asymmetrical transmission rates (bandwidth) for uplink and downlink. The asymmetry is mainly reflected in the asymmetry of the uplink rate (up to 640Kbps) and downlink rate (up to 8Mbps). On the user side, use the ADSL user terminal to decode the line transmission signal, and then transform it into an Ethernet transmission format, and connect it to the computer we use through the TCP / IP protocol to achieve broadband Internet access. [0003] With the increase in the application of ADSL user terminals, a large number of devices are damaged during use and need to be...

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) Due to the wide geographical range and large scale of the equipment provided by the equipment supplier, the maintenance time and response cycle is long, and the delivery cannot be made in time;
