Embodiment Construction

[0028] Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

[0029] A device and method for simulating broadband subscriber line faults according to the present invention mainly includes: analyzing the types and characteristic parameters of broadband subscriber line faults on site, adopting a circuit simulation method to focus on a single circuit board for simulation, and at the same time through External control commands are used to switch fault types and parameters. In addition, it also provides the functions of user line length, fault location setting, terminal switch and separator control, and simulates the field and user line-related faults and line connection status to the greatest extent, so as to achieve a better simulation than manual simulation in the laboratory. Fully simulate the effect of on-site subscriber line-related failures.

[0030] The device for simulating broadband subscriber line failure...

Description

technical field [0001] The invention relates to the testing field, in particular to a device and method for simulating broadband subscriber line faults. Background technique [0002] In order to comply with the trend of rapid development of the Internet (Internet) and meet people's urgent demand for broadband data services, various telecom operators are building broadband data networks in an all-round way. The mainstream broadband access technology currently used is ADSL (Asymmetrical Digital Subscriber Loop) technology. With ADSL technology, voice and high-speed data services can be carried on ordinary twisted-pair lines at the same time, which greatly improves the twisted-pair It also makes the large-scale application of broadband services possible. After several years of development, the number of ADSL users has continued to increase, and the number of user declarations and complaints has also increased. In addition, users have put forward higher requirements for the ser...
