Purpose of the present invention can be achieved through the following technical solutions:
A kind of ADSL subscriber terminal equipment test and maintenance system, it is characterized in that, this system comprises central controller, the digital subscriber line access multiplex machine frame, the circuit emulation attenuator, the user terminal and the computer testing platform that need test and maintenance, central controller is connected with an end of digital subscriber line access multiplex machine frame, the other end of digital subscriber line access multiplex machine frame is connected with the circuit emulation attenuator, the circuit emulation attenuator is connected with the user terminal that needs test and maintenance through interface, needs the user terminal of test and maintenance to connect the computer testing platform by another interface.
Described central controller is configured, the supervision of connection status and flow, sends data the user.
Described digital subscriber line access multiplex machine frame comprises working power, user's plate, control board and passes plate up and down.
Described user's plate, control board and pass plate up and down and all be connected on the working power, user's plate bottom connects control board, and the left side of control board connects and passes plate up and down.
Described computer testing platform is configured, launches or receive data, monitor traffic situation or line status to user terminal.
Compared with prior art, the present invention's maintenance, response of adapting to numerous producers product in time, do not influence public network.Concrete advantage is as follows:
(1) test and maintenance system can adapt to fairly large test and maintenance and sets up, and can enlarge as required;
(2) the test structure mode can be according to actual requirements definition;
(3) compare with the special test platform of factory, the present invention is cheap;
(4) outside independence and the public network, can not exert an influence to public network;
(5), monitor the attenuation state value, data-bag lost amount, the quality of judgement user terminal by the setting and the control of computer to the user job data;
(6) maintenance of the numerous producers of adaptation product, response in time.
